AMENDED MEMORANDUM DECISION AND ORDER RE: JULY 3, 2000, CROSS-MOTIONS FOR SUMMARY JUDGMENT AND FOR RECONSIDERATION

WANGER, District Judge.

This decision and order amends the decision and order filed March 2, 2001 (Doc. 346).

This matter, is before the Court on the cross-motions for summary judgment submitted by Plaintiff and the Boston Ranch Parties1 (who are Defendants, Counter-claimants, and Third-Party Plaintiffs) as to the disposition of $9,679,000 held by the Court in escrow', see Doc. 328 ¶ 1 (government’s statement of undisputed facts in support of motion for summary judgment).2 Oral argument was held on Monday, August 28, 2000.

I. THE CLAIMS

The dispute underlying this action concerns: (1) the price per acre-foot the United States Department of the Interior (“Interior”), Bureau of Reclamation (“Bureau”),3 is permitted to charge water-users who take water from the San Luis Unit of the United States Central Valley Project (“CVP”); and (2) a drainage-charge component. Interior argues 43 U.S.C. § 390ww(h), enacted in 1987, which requires the Secretary of the Interior to collect the “full cost” for providing all federal (including CVP) water, establishes the price. See Doc. 1. The water-users are members of Westlands Water District (“Westlands”),4 interpled into this action by defendant Westlands, and contend that the price was fixed at $8.00 per acre-foot by a 1963 water-service contract between Westlands and the Bureau (“1963 Contract”), authorized by the Reclamation Act of 1902, 32 Stat. 388, former 43 U.S.C. §§ 371-616 (1902), which authorizes Interior and the Bureau to contract with water districts (not individual water-users) for water service from a federal reclamation project. See, e.g., 43 U.S.C. § 485h(e) (2000).

The United States brought this action against Westlands on February 27, 1989, after Westlands refused to pay “full cost” for CVP water furnished under the 1963 Contract. It sought: (1) a declaratory judgment that Westlands violated 43 U.S.C. § 890ww(h) “as a result of its failure to pay full cost to the United States for federal reclamation project irrigation

water delivered to certain lands located within Westlands Water District which are encumbered by extended recordable contracts,” Doc. 1 ¶ 1; and (2) “a money judgment for the difference between the applicable full cost rate and the rate paid by the Westlands Water District for federal reclamation project irrigation water delivered to such lands encumbered by extended recordable contracts,” id. Westlands collects water charges by assessments on its member water-users, and remits payment to the United States according to ¶¶ 6(a) & (b) of the 1963 Contract.

The water-users object to paying more than the “Contract” price for water services by counterclaims and a third-party complaint against the federal parties, alleging nine causes of action for declaratory relief, see Doc. 48, and seeking a refund of any payments made for drainage service after 1986. These claims advance legal theories that 43 U.S.C. § 390ww(h)’s full-cost provision does not apply to the water-users.

In their November 4,1991, opposition to the government’s Motion for Order to Enter Final Judgment, the water-users raised many issues, including whether the term “service” in the 1963 Contract and recordable contracts includes “providing drainage service to recipients.” Doc. 141 17:28-18:3 (quoting Barcellos & Wolfsen, Inc. v. Westlands Water Dist., 899 F.2d 814, 823 n. 14 (9th Cir.1990) (hereinafter “Barcellos”))', see also id. at 38:17-39:10 (“The Original Westlands Landowners Are Not Precluded By The Prior Decision From Litigating The No-Drainage Issue.”).

An April 16, 1993, decision on the government’s motion for final judgment notes: “the drainage provided by the United States to Westlands has been greatly attacked. To the Court’s knowledge, no case had considered the effect upon the respective rights and duties of the parties under the various agreements.” Doc. 178 at 15:17-22. By April, 1993, only two triable issues of fact remained: (1) “appropriate issues relating to drainage,” id. at 15:23-24; and (2) “any issues pertaining to the calculation of the sum owed to the United States, and the calculation of the interest to be paid [to whomever the fund belongs],” id. at 16:3-4.

The current cross-summary judgment motions were filed July 3, 2000. See Docs. 324-26. The water-users seek summary judgment:

See Doc. 324 at vii:9-14 (water-users’ memorandum in support of partial or summary adjudication of issues). On April 3, 1997, summary judgment was granted against the water-users and for the United States on the second issue (contractual price of water). See Doc. 278 at 25:18-27:13. The water-users now move for reconsideration of that decision “in light of the Ninth Circuit’s recent Sumner Peck decision [and] for other changes of circumstances.” Doc. 324 at vii:16-17.

The government seeks summary judgment, alleging the water-users “are not entitled to any of the funds” because:

2. Regardless whether the counterclaims have a basis in law, there is no independent jurisdiction for the water-users’ assertion against the United States, given the Orff decision.

See Doc. 327 at 2:3-14 (government’s opening brief).

II. FACTUAL AND PROCEDURAL BACKGROUND

This suit arises from the Bureau’s administration of the San Luis Unit, a division of the CVP. The CVP is the nation’s largest federal reclamation project, spanning “the length of California’s Central Valley, from Shasta Dam, in the north, to the Frianb-Kern Canal, in the south.” Firebaugh Canal Co., 203 F.3d at 570. It “is a multipurpose federal reclamation project consisting of dams, hydroelectric power plants, transmission lines, and irrigation canals.” City of Santa Clara v. Watkins, 984 F.2d 1008, 1010 (9th Cir.1993). “The grand design of the Project was to conserve and put to maximum beneficial use the waters of the Central Valley of California,” Dugan v. Rank, 372 U.S. 609, 612, 83 S.Ct. 999, 10 L.Ed.2d 15 (1963), which comprises approximately one-third of California’s territory, see id.5

Construction of the San Luis Unit was authorized by the San Luis Act.6 The “principal purpose” of the San Luis Unit is to furnish irrigation to land in Merced, Fresno, and Kings counties, California. See Firebaugh Canal, 203 F.3d at 570. Westlands is the largest contractor for water from the San Luis Unit. See id. at 572. In 1963, Westlands entered into the 1963 Contract with the Bureau to purchase CVP water from the San Luis Unit at a subsidized maximum rate of $8.00 per acre-foot. See Barcellos, 899 F.2d at 816; Doc. 141 exhibit B 12:13-16. This rate included a $0.50 drainage service component. See Doc. 141 exhibit B 12:14-15. The 1963 Contract is impacted by additional considerations:

First, Section (a) of the San Luis Act requires the Government to provide drainage service to Westlands. “Any water project that brings fresh water to an agricultural area must take the salty water remaining after the crops have beén irrigated away from the service area.” Firebaugh Canal, 203 F.3d at 571.

Second, “[t]he 1963 Contract prohibits the District from furnishing Project water to an owner who wishes to use the water to irrigate his ‘excess lands,’ or lands in excess of 160 acres, unless the owner agrees in a separate, recordable contract with Interior to certain significant restraints on his rights to the excess lands.” Barcellos, 899 F.2d at 816 (footnote omitted). Between 1969 and 1974, each of the Third-Party Defendants (Boston Ranch Company,7 S. Stamoules & Co., South Boston Co., and Westhaven Farming Co.8) ex

ecuted a recordable contract with the United States to divest themselves of then-excess lands. See id. These recordable contracts are identical in every aspect, except for the party’s name and description of the property.

Id. at 824. These recordable contracts also have a provision, Article 13, that extends the ten-years period of ownership whenever “water or service from the Project may not be available to the land involved through no fault of the District or the Landowner.”

This suit concerns three issues:

A. *1902: Reclamation Act of1902.*9

Any discussion of federal water in California begins in 1902: “The Reclamation Act of 1902 provided the framework for modern day reclamation law.” Martin J. Jackley, Reclamation Law and the Bell Fourche Irrigation District: A Desperate Fight for a Way of Life in Times of Change, 40 S.D. L. REV. 478, 479 (1995) (footnote omitted). “The final westward migration of the late 1800s resulted in an enormous demand by the settlers for irrigation systems.” Peterson v. United States Dep’t of Interior, 899 F.2d 799, 802 (9th Cir.1990) (citing Paul S. Taylor, The Excess Land Law: Execution of a Public Policy, 64 YALE L.J. 477, 481-85 (1955)). “Responding to the pressing demand for federal assistance in funding water reclamation projects, Congress passed the Reclamation Act of 1902.” Id. (citing 1902 Act).

The 1902 Act had two purposes: “encourage family farming on modest-sized parcels [160 acres];” and “to increase agricultural output by subsidizing the irrigation of formerly arid and unproductive lands.” Barcellos, 899 F.2d at 824 (citing Ivanhoe Irrig. Dist., 357 U.S. at 275, 78 S.Ct. 1174; United States v. Tulare Lake Canal Co., 535 F.2d 1093 (9th Cir.1976)).10 “Congress adjusted the balance by amending the Act to authorize Interior to allow larger operators to receive water in exchange for their promise to divest themselves of excess lands.” • Id. (citing 43 U.S.C. § 423e).

Under the 1902 Act, there was very limited regulation of excess lands, because prior to the 1982 RRA, Interior did not regulate leasing of excess lands receiving subsidized water. See 32 Stat. 389 (1902) (making landowner eligible for federal project water if he owned less than 160 acres, but not limiting such water delivery to non-leased lands). The Omnibus Adjust

ment Act of 1926,11 the first major amendment to the 1902 Act, partially rectified this problem by introducing the “recordable contract” idea, which required water recipients who owned lands in excess of 160 acres to enter into a contract with Interior in which they agreed to sell their excess lands within ten years at a price not reflecting the availability of project water. See id. at 483.

“Westlands entered into a water service contract with the United States in 1963 under which the United States, through the Bureau of Reclamation, agreed to make available for Westlands’ purchase 900,000 acre-feet of water from the San Luis Unit of the Central Valley Project CCVP’).” Barcellos & Wolfsen, Inc. v. Westlands Water Dist., 849 F.Supp. 717, 720 (E.D.Cal.1993), aff'd, O’Neill v. United States, 50 F.3d 677 (9th Cir.1995). By this Contract, Interior agreed to provide CVP water to the District for 40 years. Two main provisions of the 1963 Contract are germane to this suit:

C. *1976: D.C. District Court Injunction*

On August 9, 1976, the District of Columbia district court issued an injunction preventing approval of any new contracts for excess land sales until the initiation of public rule-making proceedings. See Nat. Land for People v. Bureau of Reclamation, 417 F.Supp. 449 (D.D.C.1976).13 That injunction remained in effect until 1982.

As a result, Interior halted all land sales under recordable contracts nationwide, and did not approve land sales from 1976 through 1984. As ten years of ownership of water users’ excess lands began to expire, a problem surfaced: although under the injunction, the water-users were unable to complete sale of them excess lands, they nevertheless continued to receive subsidized water for these excess lands for more than ten years.

D. *1978: The Interior Department Increases the Water Price*

In 1978, the Solicitor of the Interior Department “issued a legal opinion stating that the $8.00 rate specified in the 1963 Contract was inadequate to recover the escalating costs of the Project and was therefore contrary to the federal reclamation laws, see 43 U.S.C. § 461, and not binding.” Barcellos, 899 F.2d at 817 (citing 1978 “Krulitz opinion”14). As a result of this opinion, “the Interior Department began to charge the District between

$13.30 and $16.40 per acre[-]foot for all Project water.” Id.

E. *1979: The Water-Users and West-lands sue to enforce the 1963 Contract’s luater-pricing provision*

In 1979, the water-users sued Westlands in state court, “seeking among other things to have the $8.00 rate enforced.” Id. Westlands joined the United States as a party, and the action was later removed to the United States District Court for the Eastern District of California. See id.15

F. *1982: Congress passes the Reclamation Reform Act of 1982 (“RRA”): “Full-Cost” water*

In 1982, Congress attempted to address the problems caused by the district court injunction against selling excess lands and the Krulitz opinion recommending full-cost rates for all water, by passing the RRA, 43 U.S.C. §§ 390aa to zz-1,16 which:

(1) required that water delivered to excess lands be paid for at full-cost; (RRA § 205(a));

(2) extended the time for landowners to dispose of their excess lands for which there were recordable contracts, by not counting the six-year effective period of the district court injunction (1976-1982) against the ten-year period for disposal of excess lands under Article 13 of the recordable contracts (RRA § 209(e)); and

(3) confined eligibility to receive subsidized water for excess lands under the recordable contracts to a total of ten years, regardless whether Article 13 extended the ownership term; but suspended termination of the right to such subsidized water (and a corresponding duty to pay “full cost”) until eighteen (18) months after the date when the Secretary began again to approve land sales (RRA § 205(c)).

Section 209(d) superseded the 1976 district court injunction, explicitly requiring Interior to establish rules for disposing of the excess lands under recordable contracts, and extended recordable contracts for a time period equal to the unexpired portion of the ten-year term when the district court injunction took effect. See 43 U.S.C. § 390ii (2000).

Section 204 of the RRA also increased the allowable amount of “non-excess” lands from 160 to 960 acres, see 43 U.S.C. § 390dd (1986), and applied this acreage limitation to all irrigated lands, whether owned or leased, see id. at § bb(6) (1986), closing the loophole that previously existed under the 1902 Act.

In the 1982 RRA, Congress also added the so-called “hammer clause,” section 203(b), codified at 43 U.S.C. § 390cc (2000), in conference committee,17 which gave districts with water contracts predating the effective date of the RRA a choice to either voluntarily and irrevocably elect to amend their contracts to comply with the RRA’s “full-cost” provisions for excess lands (and enjoy § 204’s increased 960-acre limitation for non-excess lands), or remain under the 1902 Act, with its 160-acre limitation. See 43 U.S.C. §§ 390ee(a) & (b) (2000).18

Interior resumed approval of excess land sales in July, 1984. See Doc. 1 ¶ 20; Doc. *48* ¶ 25.

G. *1986: The 1986 Barcellos Consent Judgment Re-Establishes the 1968 Contract Water Price*

Interior rescinded the 1978 Krulitz opinion on June 17, 1986 (“Tarr reeission”). See Barcellos, 899 F.2d at 819. On July 24, 1986, the parties reached a global (water rate, drainage, and excess lands) settlement memorialized by a stipulated judgment in the 1979 action (the “1986 Barcellos Judgment”), which was entered December 30, 1986. See id.19 First, the parties stipulated:

Doc. 141 exhibit E at 12 ¶ 4.1.20 The 1986 Barcellos Judgment prescribes three distinct water prices, depending on the type of land to which the water was delivered (original Westlands area, lands electing to come under the 1982 RRA’s “discretionary” provisions, and former Westplains lands21):

the higher of (a) $7.50 per acre foot or (b) the appropriate rate as of the date of delivery established pursuant to the 1982 Act [full-cost];”

Doc. 141 exhibit E at 13-14 (1986 Judgment). The water-users in this case initially chose not to be “hammered” into a 1982 RRA election; ie., did not irrevocably elect to amend their contracts to subject recordable contract lands in excess of 160 acres to the full cost provisions. See Doc. 48 ¶ 26.23 The water-users all owned original Westlands lands (Areas 1A or IB). See id. at ¶ 15. Under the 1986 Judgment, the water-users are governed by the 1963 Contract’s $8.00/acre-foot rate. The Judgment also provided for:

Barcellos, 899 F.2d at 819; see also Doc. 141 exhibit E ¶¶ 8-9, at 32-36.

Neither the 1986 Judgment nor the 1963 Contract has a provision that explicitly addresses the United States’ sovereign power to legislate. But see infra Part IV.F.3.C.

H. *1987: Congress Re-sets the water price at “Full Cost” for excess lands under recordable contract*

On December 22, 1987, less than one year after entry of the Barcellos Judgment, Congress amended federal reclamation law through the Omnibus Budget Reconciliation Act of 198724 by adding section 224(h), codified at 43 U.S.C. § 390ww(h) (2000). Section 224(h) requires the Secretary of the Interior to collect “Ml cost” for federal reclamation water delivered to excess lands under pre-RRA recordable contracts. See 43 U.S.C. § 390ww(h) (2000).25 It does this by applying section 20526 of the 1982 RRA to “all recordable contracts executed prior to October 12, 1982.”27 Section 205(a) mandates collecting the “full cost” rate for water as defined by the statute,28 a substantially higher amount

than the cost provided by the 1986 Barcel-los Judgment and the 1963 Contract. See Doc. 15 at 1-2. As of 1987, the full-cost rate was approximately $42.00 per acre-foot, see Barcellos, 899 F.2d at 819, a rate over five times the contractual rate, which includes operation, maintenance, and replacement charges, see 43 U.S.C. § 390bb(3)(A) (2000).

Aside from the “full cost” requirement, section 205(c) also limited the water-users to a total of ten years of subsidized water for their excess lands, regardless of any ownership extension period provided by Article 13 of the recordable contracts. See id. at § 390ee(c).

Shortly after ERA § 224(h) (43 U.S.C. § 390ww(h)) was enacted, Westlands brought a motion in Barcellos to specifically enforce the 1986 Barcellos Judgment, arguing that the Judgment constrained the United States to charge only the water-service rates specified in the 1986 Judgment and the 1963 Contract, $8.00 per acre-foot. See Barcellos, 899 F.2d at 819. Westlands argued that section 224(h) could not be applied to abrogate the 1986 Barcel-los Judgment; see id. at 820, because before the time section 224(h) was enacted, a judgment that ordered Interior to perform the terms of the 1963 Contract had already been entered. In the alternative, West-lands alleged if section 224(h) applied to the 1963 Contract and the 1986 Barcellos Judgment, then it impaired the obligation of the Judgment, a contract, violating due process and separation of powers. See id. The District Court denied Westlands relief. An appeal followed. See id.

I. *1989: The Instant Suit*

After the Barcellos appeal was filed, in 1989, the United States brought this action against Westlands Water District: First, for a declaratory judgment that Westlands violated RRA section 224(h)29 “as a result of its failure to pay full cost to the United States for federal reclamation project irrigation water delivered to certain lands located within Westlands Water District which are encumbered by extended recordable contracts,” Doc. 1 ¶ 1; and second, for a “money judgment for the difference between the applicable full cost rate and the rate paid by the Westlands Water District for federal reclamation project irrigation water delivered to such lands encumbered by extended recordable contracts,” id.

Westlands moved to stay the action pending the Barcellos appeal. See Doc. 5. The motion for stay was denied. See Doc. 15 at 4.

J. *1989: The Counter-claims, Request for Interpleader, and the Joinder of, inter alia, the Water-Users*

On July 10, 1989, Westlands answered the complaint and filed a “counterclaim for interpleader.” See Doc. 19. It requested that: (1) “the court order that Water Users be made party defendants to respond to the complaint and to [the instant] counterclaim;” (2) “the United States and

Water Users be required to interplead and settle among themselves their respective rights to the money collected by West-lands;” (3) “the court adjudge who is entitled to the sum collected by Westlands;” (4) “the court discharge Westlands from all liability except to the person(s) the court shall adjudge entitled to the sum of money;” and (5) ‘Westlands recover its costs and attorneys’ fees.” Id.

Because Westlands maintained that Section 390ww(h) did not apply to it, beginning July 28, 1989, Westlands began depositing with the Court assessment monies it collected from the water-users that they requested Westlands withhold from the United States. See Doc. 25. On September 15, 1989, the court held that West-lands had “the right to [interjplead the interested party.” Doc. 30 at 5.30

On November 3, 1989, Westlands filed a second amended counterclaim. See Doc. 38. It named, inter alia, water-users Boston Ranch Company, S. Stamoules & Company, South Boston Company, and Wes-thaven Farming Company. On January 26, 1990, the water-users, including the Boston Ranch parties, replied to the second amended counterclaim, see Doc. 47, and filed a counterclaim and third-party-complaint against the federal parties, see Doc. 48. The water-users alleged nine causes of action for declaratory relief, seeking to avoid application of Section 390ww(h)’s full-cost provision. See id.

K. *1990: Issuance of the Stay and the Barcellos Opinion*

On May 11, 1990, the parties stipulated to a stay pending the outcome of the Bar-cellos appeal. See Doc. 110.

The Barcellos appellate decision issued March 16, 1990, and was amended June 7, 1990, on denial of rehearing and rehearing en banc. See Barcellos, 899 F.2d at 814. In a divided opinion, the Ninth Circuit rejected the water users’ contentions that RRA section 224(h)31 did not apply to the 1963 Contract: “There is no fairly debatable construction of § 224(h) that would exempt the [water-users] from its provisions.” Id. at 821. The Ninth Circuit also rejected the claim that section 224(h), as applied to the water users, was unconstitutional. See id. “To prevail in their claim that § 224(h) deprived them of their contract right to water at $8.00 per acre foot for excess lands receiving water for more than ten years, the [water-users] must first, of course, demonstrate that they had such a contract right before the enactment of § 224(h).” Id. (citing Nat’l R.R. Passenger Corp. v. Atchison, Topeka & Santa Fe Ry. Co., 470 U.S. 451, 105 S.Ct. 1441, 84 L.Ed.2d 432 (1985)) (emphasis in original). Then, “[i]f they can demonstrate they had ‘such a right, they must then show a substantial impairment of that right.” Id. (citing Nat’l R.R. Passenger Corp., 470 U.S. at 451, 105 S.Ct. 1441). The Court of Appeals found the water-users: “never had a contractual right to receive more

than ten years of water for their excess lands, [and] Congress, in enacting § 224(h), did not deprive them of a property right within the meaning of the fifth amendment.” Id. at 825.32

On December- 3, 1990, the Supreme Court denied certiorari. See Boston Ranch Co. v. Dep’t of the Interior, 498 U.S. 998, 998, 111 S.Ct. 555, 112 L.Ed.2d 562 (1990). The res judicata effect of the 1990 Barcellos appellate decision on the issues presented by this suit must be decided.

L. *1991: The Government Moves for Entry of Judgment*

On July 30, 1991, the Government moved for entry of final judgment. See Doc. 127. It argued that the 1990 Barcel-los appellate decision disposed of all issues in this lawsuit. See id. at 6-7. The water-users argued that the failure to provide drainage, an issue not decided by Barcel-los, affects that calculus. See Doc. 141. On April 16, 1993, the motion for final judgment was denied, see Doc. 178, because two triable issues of fact were identified. First, were “appropriate issues relating to drainage.” Id. at 15:16-24:

Second, were “any issues pertaining to the calculation of the sum owed to the United States, and the calculation of the interest to be paid them.” Id. at 16:3-4.

“Drainage issues” were brought to the forefront in approximately June, 1986, when the United States ceased providing drainage to Westlands and the San Luis Unit. The San Luis Feasibility Report, prepared by the Secretary of the Interior in 1956, contemplated “a system of tile drains that would empty into an interceptor drain that would convey the water 197 miles to the Contra Costa Delta for disposal.” Firebaugh Canal Co., 203 F.3d at 571. Construction of part of this interceptor drain was initiated, and by 1975, the middle forty (40) percent of the drain, approximately 82 miles, was built. See Doc. 328 ¶ 14; Doc. 336 ¶ 14 (undisputed facts). In 1975, however, “the Secretary suspended construction of the interceptor drain, citing ‘questions’ and ‘concerns’ raised in the public arena.” Firebaugh Canal Co., 203 F.3d at 571.

Rather, a subsurface drainage collector system was constructed. See id. Drainage service utilizing this system commenced in 1978. See id. It operated until June, 1986, as follows:

Id. In mid-1983, however, “waterfowl nesting studies at Kesterson Reservoir revealed instances of embryo deformity and mortality.” Id.

ta. Like other metals, selenium can impair the growth of crops and is hazardous to human and animal life when present in high concentrations.

Id. at 571-72. As a result, “[ojn March 15, 1985, the Secretary of the Interior announced that it would close the Reservoir.” Id. at 572.

By June, 1986, “the drains at Westlands were plugged and the middle portion of the interceptor drain was closed.” Id. The United States continued to deliver water to Westlands after June, 1986, but without providing drainage service.33 Ultimately, the Government took the position that “subsequent changes in the law and environmental knowledge made compliance with the San Luis Act impossible, and thereby excused the United States from performing th[e] duty [to provide drainage].” Id. Affected landowners filed suit “seeking completion of the master drain to the Contra Costa Delta.” Id. at 571. Two suits were filed, Sumner Peck Ranch, Inc. v. Bureau of Reclamation, No. CV-F-91-048, and Firebaugh Canal Co. v. United States, No. CV-F-88-634, which “were partially consolidated to resolve the plaintiffs’ common allegation that the Secretary of Interior is required by law to construct facilities to drain agricultural drainage water from certain lands in Westlands Water District.” Id. Such a statutory duty was found, as was breach of the duty to provide drainage. Judgment was entered for the landowners on these issues on March 12, 1995. See Firebaugh Canal Co. v. United States, No. CV-F-88-634 (E.D.Cal. Mar. 12, 1995) (Doc. 442).

The Government appealed, reiterating its arguments that it had no drainage obligation under the San Luis Act, or alternatively, if it did have such an obligation, the obligation had been excused by factual or legal impossibility.

M. *1991: Released Funds*

On March 28, 1994, the Government moved to release all funds in the escrow account, except the funds claimed by claimants. See Doc. 216. All counsel agreed $1,733,201.00 could be released to the United States, see Doc. 236 at 6:9-11, and on December 7, 1994, the Government’s motion was granted to the extent of the agreed sum, see id. at 6:13-14; 7:1-5.

N. *1996: Cross-motions for Summary Judgment Re: Remaining Funds*

On August 23, 1996, the Government sought a final order to distribute the remainder of the escrow account funds to it. See Doc. 247. On August 26, 1996, the water-users filed a cross-motion for partial judgment on the pleadings, or, in the alternative, summary judgment against the United States. See Doc. 250. They advanced two theories: first, that the United States breached contracts with the water-users and Westlands. Specifically: Article 13 of their recordable contracts provides that the Secretary of Interior holds power of attorney over their excess lands for ten years after the recordable contracts were signed. This ten-year period is tolled when “water or ‘service’ ” from the CVP was not available. The water-users contend that the term “service” includes ade

quate “drainage service,” and that because little or no drainage service has ever been provided, the ten-year period has been tolled and never expired. They argue, if the ten-year period never expired, the original contract terms, including the $8.00 per acre-foot price, are still in effect, and section 224(h)34 is inapplicable to water delivered to their excess lands under the extended recordable contracts.

Assuming, arguendo, that Barcellos makes section 224(h)35 applicable to their contracts, the water-users contend the government’s failure to provide drainage service breached the 1963 Contract and their recordable contracts, entitling them to damages. See Doc. 250 at 17:3-8. They anticipate the Government’s assertion of the unmistakability and the sovereign acts defenses, preemptively arguing these defenses fail under United States v. Winstar Corp., 518 U.S. 839, 116 S.Ct. 2432, 135 L.Ed.2d 964 (1996) (hereinafter “Winstar ”).

Third, assuming, arguendo, that there was no breach of contract by the Government’s failure to provide drainage service, the water-users assert a non-contractual theory of recoveiy: restitution of all drainage-related payments, because they paid for drainage, but never received it. See id. at 23.

A memorandum decision and order on these cross-motions issued April 3, 1997. See Doc. 278. As to the first argument, the term “ ‘service’ must include ‘drainage service.’ ” Id. at 25:18-19. ' However, as Barcellos teaches: “It does not follow ... that Claimants had a right to subsidized water as long as they owned their excess land.” Id. at 25:23-24. The water-users’ interpretation that the self-extended recordable contracts made RRA § 224(h)36 inapplicable was “strained at best.” Id. at 26:26. This April, 1997, memorandum decision held that RRA section 224(h) “does not abridge any contract right because Claimants have no absolute contract right to the unqualified delivery of water at the $8.00 rate.” Id. at 27:10-12. Any Wins-tar analysis was found unnecessary, because “no enforceable contract right existed that § 224(h) could breach.” Id. at 27:12-13. On the first two issues, summary judgment was granted against the water-users and for the Government, holding that section 224(h) did not wrongfully impair the water-users’ contractual rights. See id. at 27:14^15. This holding was based on Barcellos. See id. at 24-27. For reasons stated below, reconsideration of these rulings is appropriate.

The Government did not address the water-users’ non-contractual theory of recovery. See id. at 26:21. Finding that the Firebaugh Canal Co. appeal would impact the water-users’ unjust enrichment theory, their cross-motion for summary judgment was denied without prejudice, pending the Ninth Circuit’s decision in Firebaugh Canal Co. See id. at 27:22-28:20. The Ninth Circuit decided Firebaugh Canal Co. on February 04, 2000.

P. *2000: Firebaugh Canal Co. v. United States*

In Firebaugh Canal Co., the Ninth Circuit rejected the Government’s position that it need not provide drainage to the San Luis Unit contractors, see Firebaugh, 203 F.Sd at 568:

seeking completion of the master drain to the Contra Costa Delta. See Sumner Peck Ranch, Inc. v. Bureau of Reclamation, 823 F.Supp. 715 [(E.D.Cal.1993)]; Firebaugh Canal Co. v. United States, No. CV-F-88-634.... In May of 1992, these lawsuits were partially consolidated to resolve the plaintiffs’ mutual allegation that the Secretary of Interior is required by law to construct facilities to drain agricultural drainage water from certain lands in Westlands Water District.

Id. at 572. The United States appealed the entire district court judgment that, inter alia:

Id. at 570 (quoting without citing the district court judgment). The Ninth Circuit affirmed the district court holding that: (1) the Government has a duty to provide drainage to the San Luis Unit; (2) performance of that duty has been unreasonably and unlawfully delayed; and (3) the time has now come to provide such drainage service. See id. at 575.37

Q. *2000: Cross Motions Re: Remaining Funds*

The current cross-summary judgment motions were filed July 3, 2000. See Docs. 324-28. “In light of the Ninth Circuit’s recent Firebaugh decision” and “for other changes of circumstances,” Doc. 324 at vii: 14-18, the water-users seek reconsideration of the April 3, 1997, memorandum and order (Doc. 278), which held that they were required to pay the “full cost” rate as defined by RRA § 224(h). The water-users have two basic arguments: (1) they re-assert the contractual interpretation argument that the 1963 Contract’s subsidized water rate applies to excess lands during Article 13 extension periods caused by the government’s failure to provide drainage service; and (2) they are owed restitution for any drainage payments, because the government has not provided drainage.

The water-users support these arguments by claiming Barcellos is inapposite after Winstar and Firebaugh.38 Their previously advanced Winstar argument was rejected in the 1997 memorandum decision, because “no enforceable contract right existed that § 224(h) could breach.” Doc. 278 at 27:9-15. The water-users ar

gue Firebaugh provides a factual basis to conclude that the recordable contracts may have been extended by failure to provide drainage service. See Doc. 324 at 13:14-19. The contract-extension argument is not new; its viability has been acknowledged. See Doc. 278 at 25:18-19 (“Claimants persuasively argue ‘service’ must include ‘drainage service.’ ”). Nonetheless, even if recordable contracts are extended, the United States is not necessarily required to provide, in perpetuity, $8.00 per acre-foot water to landowner parties to the recordable contracts. See id. at 26:3-8 (citing Barcellos, 899 F.2d at 823). The water-users provide no new arguments, law, or facts as to the breach of contract issue raised regarding water-service prices.

However, no case has yet interpreted, outside of dictum, whether the 1963 Contract, the recordable contracts, and the 1986 Barcellos Judgment afford the water-users contract-priced (rather than full-cost) water for their excess lands during any time extended recordable contracts are effective if drainage service was not provided (which will be decided in the Firebaugh Canal Co. remand). This issue directly affects whether summary judgment should be granted.

Two other issues remain. First, the water-users argue they are entitled to restitution of the fees paid for drainage facilities and service under a theory of unjust enrichment, because the United States has not yet provided for such facilities and service. In addition, they argue they are entitled to interest on the interpled funds.

The United States rejoins that the water-users “are not entitled to any of the funds” because: (1) the Bureau has no discretion “other than to collect full cost;” (2) based on Orff, no independent jurisdiction exists to hear the water-users’ counterclaims; and (3) Firebaugh Canal Co. held the United States was not required to construct the interceptor drain under the San Luis Act, which “was the quid pro quo” for the water-users’ drainage payments. See Doc. 327 at 2:3-14. The government’s last argument addresses only part of the landowners’ drainage claim. The landowners contend that even if “drainage” does not include the interceptor drain with East Bay terminus, they have not received “any drainage,” i.e., drainage service to which the Court of Appeals held they were entitled under the San Luis Act, which breaches their recordable contracts and the contract embodied within the 1986 Barcellos Judgment.

R. Types of Funds

There are three different types of funds on deposit in this case:

III. LEGAL STANDARD

A. Summary Judgment

“Summary judgment ‘shall be rendered forthwith if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to

any material fact and that the moving party is entitled to a judgment as a matter of law.’ ” *7-Up Bottling Co. of Jasper Inc. v. Varni Bros. Corp. (In re Citric Acid Litig.), 191 F.3d 1090, 1093 (9th Cir.1999) (quoting Fed. R. Civ. P. 56(c)). A genuine issue of fact exists when the non-moving party produces evidence on which a reasonable trier of fact could find in its favor viewing the record as a whole in light of the evidentiary burden the law places on that party. See Triton Energy Corp. v. Square D Co., 68 F.3d 1216, 1221 (9th Cir.1995); see also Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 252-56, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). The non-moving party -cannot simply rest on its allegation without any significant probative evidence tending to support the complaint. See U.A. Local 343 v. Nor-Cal Plumbing, Inc.,* 48 F.3d 1465, 1471 (9th Cir.1994).

Celotex Corp. v. Catrett, 477 U.S. 317, 322-23, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986).

The more implausible the claim or defense asserted by the opposing party, the more persuasive its evidence must be to avoid summary judgment. See United States ex rel. Anderson v. N. Telecom, Inc., 52 F.3d 810, 815 (9th Cir.1995); see also Van Westrienen v. Americontinental Collection Corp., 94 F.Supp.2d 1087, 1094 (D.Or.2000) (“when the non-moving party’s claims are factually implausible, that party must come forward with more persuasive evidence than would otherwise be required.”) (citing Cal. Architectural Bldg. Prods., Inc. v. Franciscan Ceramics Inc., 818 F.2d 1466, 1470 (9th Cir.1987)). Nevertheless, “the evidence of the non-movant is to be believed and all justifiable inferences are to be drawn in its favor.” Murphy Exploration & Prod. Co. v. Oryx Energy Co., 101 F.3d 670, 673 (Fed.Cir.1996) (quoting Liberty Lobby, 477 U.S. at 255, 106 S.Ct. 2505; Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986)). A court’s role on summary judgment, however, is not to weigh the evidence, i.e., issue resolution, but rather to find genuine factual issues. See Abdul-Jabbar v. Gen. Motors Corp., 85 F.3d 407, 410 (9th Cir.1996).40

B. Reconsideration

“[A] motion for reconsideration of summary judgment is appropriately brought under either Rule 59(e) or Rule 60(b).” Fuller v. M.G. Jewelry, 950 F.2d 1437,

1442 (9th Cir.1991) (citing Taylor v. Knapp, 871 F.2d 803, 805 (9th Cir.1989) (citing Backlund v. Barnhart, 778 F.2d 1386, 1388 (9th Cir.1985) (citing Stephenson v. Calpine Conifers II, Ltd., 652 F.2d 808, 811 (9th Cir.1981)))). A 59(e) motion must be brought no later than ten (10) days following entry of the final judgment, see Fed.R.Civ.P. 59(e) (1992), whereas a 60(b) motion must be brought within a “reasonable” time, which cannot be more than one year if the motion is based on mistake ((b)(1)), newly-discovered evidence ((b)(2)), or fraud ((b)(3)), see Fed.R.Civ.P. 60(b)(l)-(b)(3) (1992). A Rule 59(e) motion for reconsideration that is filed outside the ten-day period may be interpreted as a Rule 60(b) motion. Accord Taybr, 871 F.2d at 805 (construing reconsideration motion labeled as Rule 60 motion as a Rule 59 motion, because it was filed eight days after entry of summary judgment, within the time period for Rule 59(e)).41

“A motion for reconsideration of summary judgment is appropriately brought under Rule 59(e).” Backlund, 778 F.2d at 1388 (citing Stephenson, 652 F.2d at 811). Rule 59(e) reconsideration is appropriate where: the district court is presented with newly-discovered, evidence or committed clear error; the initial decision was manifestly unjust; or if there is an intervening change in controlling law. See 389 Orange St. Partners v. Arnold, 179 F.3d 656, 665 (9th Cir.1999) (citing Sch. Dist. No. 1J, Multnomah County, Or. v. ACandS, Inc., 5 F.3d 1255, 1263 (9th Cir.1993) (hereinafter “Sch. Dist. No. 1J ”) (citing All Haw. Tours, Inc. v. Polynesian Cultural Ctr., 116 F.R.D. 645, 648 (D.Haw. 1987), rev’d on other grounds, 855 F.2d 860, 1988 WL 86203 (9th Cir.1988))). A reconsideration motion should not merely present arguments previously raised, or which could have been raised in the initial summary judgment motion. See Backlund, 778 F.2d at 1388 (“The motion was properly denied here because ... it presented no arguments that had not already been raised in opposition to summary judgment.”); United States v. Navarro, 972 F.Supp. 1296, 1299 (E.D.Cal.1997) (“[Mjotions to reconsider are not vehicles permitting the unsuccessful party to ‘rehash’ arguments previously presented.... Nor is a motion to reconsider justified on the basis of new evidence which could have been discovered prior to the court’s ruling.... Finally, ‘after thoughts’ or ‘shifting of ground’ do not constitute an appropriate basis for reconsideration.”) (citations omitted).42 “These relatively restrictive standards ‘reflect district courts’ concern for preserving dwindling resources and promoting judicial efficiency.’ ” Navarro, 972 F.Supp. at 1299 (quoting Costello v. United States Gov’t, 765 F.Supp. 1003, 1009 (C.D.Cal.1991)) (alteration omitted).

Rule 60(b) permits reconsideration of a district court order based on: (1) mistake, inadvertence, surprise, or excusable neglect; (2) newly-discovered evidence that supports grounds for a new trial under Rule 59; (3) fraud by an adverse party; (4) the judgment is void; (5) the judgment has been satisfied, released or discharged; or (6) any other reason justifying relief

from the operation of the judgment. See Fed.R.Civ.P. 60(b)(1)-(b)(6) (1992).43

Rule 60 reconsideration is generally appropriate in three instances: 1) when there has been an intervening change of controlling law, 2) new evidence has come to light, or 8) when necessary to correct a clear error or prevent manifest injustice. Sch. Dist. No. 1J, 5 F.3d at 1262; see also E.D. Cal. L.R. 78—280(k).44 “A motion for reconsideration is not a vehicle to 'reargue the motion or to present evidence which should have been raised before.” Bermingham v. Sony Corp. of Am., Inc., 820 F.Supp. 834, 856 (D.N.J. 1992), aff'd, 37 F.3d 1485 (3d Cir.1994) (citing Weyerhaeuser Corp. v. Koppers Co., 771 F.Supp. 1406, 1419 (D.Md.1991)). “ ‘A party seeking reconsideration must show more than a disagreement with the Court’s decision, and “recapitulation of the cases and arguments considered by the court before rendering its original decision fails to carry the moving party’s burden.” ’ ” Id. at 856-57 (quoting G-69 v. Degnan, 748 F.Supp. 274, 275 (D.N.J.1990)) (quoting Carteret Sav. Bank, F.A. v. Shushan, 721 F.Supp. 705, 709 (D.N.J.1989)). To succeed, a party must set forth facts or law of a strongly convincing nature to induce the court to reverse its prior decision. See, e.g., Kern-Tulare Water Dist. v. City of Bakersfield, 634 F.Supp. 656, 665 (E.D.Cal.1986), aff'd in part and rev’d in part on other grounds, 828 F.2d 514 (9th Cir.1987).45

IV. DISCUSSION

A. Reconsideration

The water-users meet the requirements for reconsideration under Rule 60, because a clear error may have been made in, or a manifest injustice may occur as a result of, the 1997 memorandum decision’s finding that Barcellos is dispositive of the contractual interpretation issues presented.

B. Impact of the 1990 Barcellos46 decision

Before a re-interpretation of the 1963 Contract, the Recordable Contracts, and the 1986 Barcellos Judgment can be performed, the extent to which the 1990 Bar-cellos appellate decision interprets then-disputed provisions as an explicit holding (rather than dicta), which is law of the case, must be decided.

Barcellos definitively answers the “quite narrow,” Barcellos, 899 F.2d at 823, question whether the 1963 Contract and/or recordable contracts gave the water-users the unqualified right to water at the $8.00 contract rate for their excess lands during any extended period of the recordable contracts (ie., beyond initial the 10-year term) caused by their inability to sell those excess lands due to a federal district court injunction against such sales in effect from 1976 to 1982. It holds that the contracts do not afford the water-users an unlimited right to low-cost water service for excess lands during Article 13 ownership extension periods caused by the Bureau’s failure to approve land sales, making it impossible to sell those excess lands, and accordingly, § 224(h) did not deprive them of anything. See id. at 823-26. This conclusion is based on a rejection of the water-users’ argument that Article 13 of the recordable contracts', which tolls the ten-year period during times when “water or service” was not provided, included the “service” of approving excess land sales.47 See id. at 823. The basis for this holding was that approving land sales was neither “water” nor “service” within the intended meaning of Article 13. See id.

The 1997 memorandum decision interpreted the Barcellos appellate decision to find that regardless of the intended meaning of the term “service” in Article 13, the water-users had no contract right to subsidized water during any period of “extended” (more than 10 years’) ownership of their excess lands,48 in view of the Barcel-

los’ finding that section 224(h) applied to the 1963 Contract and the 1986 Judgment. See, e.g., id. at 823-25. Upon closer scrutiny, this finding was not on an issue necessary to the Circuit Court’s decision, because once the Court found that “service” did not include approving land sales, the case was over: there was no contract provision to authorize an Article 13 extension.

Barcellos is factually distinguishable, because the only extending event at issue was Interior’s non-approval of excess land sales during 1976 until 1984. The event of an express Article 13 extending cause, absence of drainage “service,” was not at issue. Because “land sale approval” was not encompassed by the Article 13 terms, “water or service,” the gratuitous discussion in Barcellos regarding the right to subsidized water during extension periods was not necessary to the decision; it is dicta. See Trent v. Valley Elec. Ass’n, Inc., 195 F.3d 534, 537 (9th Cir.1999) (interpreting prior panel’s statement as dicta and therefore not binding under the law of the case doctrine) (citing Milgard Tempering, Inc. v. Selas Corp. of Am., 902 F.2d 703, 715 (9th Cir.1990)); Export Group v. Reef Indus., Inc., 54 F.3d 1466, 1472 (9th Cir.1995) (rejecting statements not necessary to another decision as dicta and declining to follow as binding precedent); Sarnoff v. Am. Home Prods. Corp., 798 F.2d 1075, 1084 (7th Cir.1986) (“A dictum is a statement in a judicial opinion that could have been deleted without seriously impairing the analytical foundations of the holding — that, being peripheral, may not have received the full and careful consideration of the court that uttered it.”) (Posner, J.); see also OXY USA, Inc. v. Babbitt, 230 F.3d 1178, 1184 (10th Cir.2000) (“dicta are ‘statements and comments in an opinion concerning some rule of law or legal proposition not necessarily involved nor essential to determination of the case in hand.’ ”) (quoting Rohrbaugh v. Celotex Corp., 53 F.3d 1181, 1184 (10th Cir.1995) (quoting Black’s Law DictionaRY 454 (6th ed.1990))); United States v. Wade, 152 F.3d 969, 973 (D.C.Cir.1998) (“Because that issue was not before the court, its overly broad language would be obiter dicta and not entitled to deference.”) (citing cases); Nephew v. City of Aurora, 766 F.2d 1464, 1466 (10th Cir.1985) (rejecting dicta from prior panel, although facially on point); Blaok’s Law Dictionary 465 (7th ed.1999) (defining judicial dictum as “[a]n opinion by a court on a question that is directly involved, briefed, and argued by counsel, and even passed on by the court, but that is not essential to the decision.”) (emphasis added).49 Dicta are not binding as law of the case. See, e.g., Trent, 195 F.3d at 537.50

Barcellos did not address the different issue raised here: the effect of an absence of drainage service on the full-cost provision and the Article 13 extension period. In Barcellos, the water-users argued that the combination of the 1963 Contract and recordable contracts entitled them to subsidized water for their excess lands during any time they own these lands (“extended period”) after the initial ten-year period of subsidized water lapsed.51 Unlike Barcel-los, the term “service” under Article 13 encompasses drainage service, which the water-users claim was not provided in any of the years in question, with the alleged effect that the ten-year period of subsidized water and ownership is indefinitely extended until such time drainage service is provided.52

The Barcellos pronouncement that there was no possibility that a right to subsidized water existed during any Article 13 extension periods, for ihore than 10 years, is dicta. It is not binding as law of the case. Careful re-analysis of Barcellos leads to the conclusion that it does not decide the issues presented here. The entire 1963 Contract was not interpreted by the Barcellos majority. Further interpretation of the 1963 Contract by another panel in O’Neill shows that extrinsic evidence may be relevant. See O’Neill, 50 F.3d at 682.

C. Contractual Interpretation

When interpreting a contract, the plain language within the four corners of the contract must first be examined to determine the mutual intent of the contracting parties. See, e.g., United States v. Clark, 218 F.3d 1092, 1096 (9th Cir.2000) (“Following traditional rules of contract interpretation, we must examine the plain language of the term in the context of the document as a whole.”) (quoting sources). In “cases of contracts, language is to be given, if possible, its usual and ordinary meaning. The object is to find out from the words used what the parties intended to do.” Fla. Cent. R.R. Co. v. Schutte, 103 U.S. (Mem.) 118, 140, 13 Otto 118, 26 L.Ed. 327 (1880). “Further, business contracts must be construed with business sense, as they naturally would be understood by intelligent men of affairs.” Giove v. Dep’t of Transp., 230 F.3d 1333, 1340-41 (Fed.Cir.2000) (quoting N. German Lloyd v. Guar. Trust Co., 244 U.S. 12, 24, 37

S.Ct. 490, 61 L.Ed. 960 (1917); Deloro Smelting & Ref. Co. v. United States, 161 Ct.Cl. 489, 317 F.2d 382, 387 (1963) (quoting N. German Lloyd, 244 U.S. at 24, 37 S.Ct. 490)) (alteration marks and internal quotation marks omitted).

“A written contract must be read as a whole and every part interpreted with reference to the whole, with preference given to reasonable interpretations.” Klamath Water Users Protective Ass’n v. Patterson, 204 F.3d 1206, 1210 (9th Cir.), cert. denied, — U.S. -, 121 S.Ct. 44, 148 L.Ed.2d 14 (2000) (citing Kennewick Irrigation Dist. v. United States, 880 F.2d 1018, 1032 (9th Cir.1989)). “The normal rule of construction, of course, is that courts must interpret contracts, if possible, so as to avoid internal conflict.” Trident Ctr. v. Conn. Gen. Life Ins. Co., 847 F.2d 564, 566 (9th Cir.1988) (citing sources). “The interpretation of a contract is a mixed question of law and fact.” Tyler v. Cuomo, 236 F.3d 1124, 1134 (9th Cir.2000) (quoting Klamath Water Users Protective Ass’n, 204 F.3d at 1210 (citing O’Neill, 50 F.3d at 682 (citing Carpenters Pension Trust Fund v. Underground Constr. Co., 31 F.3d 776, 778 (9th Cir.1994)))).

“A contract is ambiguous if reasonable people could find its terms susceptible to more than one interpretation. The fact that the parties dispute a contract’s meaning does not establish that the contract is ambiguous.” Barcellos & Wolfsen, Inc., 849 F.Supp. at 721 (quoting Kennewick Irrigation Dist., 880 F.2d at 1032 (quoting Int’l Union of Bricklayers & Allied Craftsman Local No. 20 v. Martin Jaska, Inc., 752 F.2d 1401, 1406 (9th Cir.1985))) (internal citation and citation marks omitted). “[T]he determination whether contract language is ambiguous is a question of law.” Tyler, 236 F.3d at 1134 (quoting Klamath Water Users Protective Ass’n, 204 F.3d at 1210 (citing O’Neill, 50 F.3d at 682 (citing Carpenters Pension Trust Fund, 31 F.3d at 778))).

Federal common law controls contractual interpretation if the United States is a party to the contract and entered into it pursuant to federal law. See Klamath Water Users Protective Ass’n, 204 F.3d at 1210 (citing O’Neill, 50 F.3d at 682).53 “In fashioning federal rules, guidance is gained from general principles for interpreting contracts.” Saavedra v. Donovan, 700 F.2d 496, 498 (9th Cir.1983) (citing United States v. Seckinger, 397 U.S. 203, 209-11, 90 S.Ct. 880, 25 L.Ed.2d 224 (1970)).

Although “[u]nder the parol evidence rule, a court looks to, and enforces, the plain language of a contract and does not look to ‘extrinsic evidence to interpret the terms of an unambiguous written instrument,’ ” United States v. Nunez, 223 F.3d 956, 958 (9th Cir.2000) (quoting Wilson Arlington Co. v. Prudential Ins. Co. of Am., 912 F.2d 366, 370 (9th Cir.1990) (citing Trident Ctr., 847 F.2d at 568-69)) (ellipses omitted),54 because the Uniform

Commercial Code (“U.C.C.”) is another source of federal common law upon which a district court may rely when interpreting a contract where the federal government is a party,55 “[t]he Code permits the [Court to] use ... extrinsic evidence in a manner that substantially narrows the traditional application of the parole evidence rule.” O’Neill, 50 F.3d at 684. For example, under U.C.C. § 2-202(a), evidence of prior dealings, usage, and performance is also relevant in determining whether the contract is ambiguous. See U.C.C. § 2-202(a);56 see also Trident Ctr., 847 F.2d at 569 (noting that under California law, “it matters not how clearly a contract is written, nor how completely it is integrated, nor how carefully it is negotiated, nor how squarely it addresses the issue before the court: the contract cannot be rendered impervious to attack by parol evidence. If one side is willing to claim that the parties intended one thing but the agreement provides for another, the court must consider extrinsic evidence of possible ambiguity.”) (discussing Pac. Gas & Elec. Co. v. G.W. Thomas Drayage & Rigging Co., 69 Cal.2d 33, 69 Cal.Rptr. 561, 442 P.2d 641 (1968)) (Kozinski, J.). However, if a contractual term is ambiguous, extrinsic evidence may be utilized to interpret the “parties’ intent in light of earlier negotiations, later conduct, related agreements, and industry-wide custom.” Pace v. Honolulu Disposal Serv., Inc., 227 F.3d 1150, 1158 (9th Cir.2000) (quoting Pierce County Hotel Employees & Rest. Employees Health Trust v. Elks Lodge, 827 F.2d 1324, 1327 (9th Cir.1987)) (internal quotation marks and ellipsis omitted).57

The U.C.C.' specifically differentiates between a usage of trade; a course of dealing; and a course of performance. A usage of trade is:

vocation or trade as to justify an expectation that it will be observed with respect to the transaction in question. The existence and scope of such a usage are to be proved as facts.

U.C.C. § 1-205(2). A course of dealing is:

Id. at (1).

Id. at § 2-208.

If an ambiguity persists in the contract after resort to extrinsic evidence, the doctrine of contra ‘proferentem58 must be applied, which construes any ambiguity in the contract against the drafter. See, e.g., Vizcaino v. Microsoft Corp., 97 F.3d 1187, 1194 (9th Cir.1996) (citing Barnes v. Indep. Auto. Dealers Ass’n of Cal. Health & Welfare Benefit Plan, 64 F.3d 1389, 1393 (9th Cir.1995) (“We must construe ambiguities in an ERISA plan against the drafter and in favor of the insured.”) (citing Mongeluzo v. Baxter Travenol Long Term Disability Benefit Plan, 46 F.3d 938, 942 (9th Cir.1995)); Babikian v. Paul Revere Life Ins. Co., 63 F.3d 837, 840 (9th Cir.1995); Mongeluzo, 46 F.3d at 942 (noting that Kunin v. Benefit Trust Life Ins. Co., 910 F.2d 534, 539-41 (9th Cir.1990), adopted the well-established doctrine of contra proferentem as federal common law)).59

Last, if no other method can adequately interpret the contractual provision in question, the court allocates the risk of the unforeseeable loss to the more efficient risk bearer. See, e.g., Robert Cooter & Thomas Ulen, Law & Economics 200-03 (3d ed.2000); Ian Ayers & Robert Gertner, Filling Gaps in Incomplete Contracts: An Economic Theory of Default Rules, 99 Yale L.J. 87 (1989).

Contractual interpretation principles apply to the 1963 Contract, the recordable contracts, and the 1986 Judgment, because a federal court consent judgment “is a negotiated agreement that is entered as a judgment of the court, ... has attributes of both contracts and judicial decrees,” Bragg v. Robertson, 83 F.Supp.2d 713, 717 (S.D.W.Va.2000) (citations omitted),60 and is interpreted according to federal contract law, see, e.g., United States v. Gila Valley Irrigation Dist., 31 F.3d 1428, 1433 (9th Cir.1994) (“consent decrees

‘should be construed basically as contracts.”’) (quoting United States v. ITT Cont’l Baking Co., 420 U.S. 223, 236-37, 95 S.Ct. 926, 43 L.Ed.2d 148 (1975)); Hook v. Ariz., Dep’t of Corrs., 972 F.2d 1012, 1014 (9th Cir.1992) (“[C]onsent decrees are essentially contractual agreements that are given the status of a judicial decree. Contract principles are generally applicable in our analysis of consent decrees, provided contract analysis does not undermine the judicial character of the decree.”) (citing Thompson v. Enomoto, 915 F.2d 1383, 1388 (9th Cir.1990)).

a. Article IS “Service” includes drainage service

Do the Article 13 extension period provisions from the recordable contracts apply to lack of drainage service? The “Definitions” section of the 1963 Contract does not explicitly define “service.” The “Explanatory Recitals” expressly state that Westlands contracts with the government to furnish the landowners with “a supplemental water supply from the Project and for drainage service.” 1963 Contract, at 13-16 (emphasis added). “[Tjhroughout the documents defining the relationship among the landowners, the District, and Interior, ‘service’ appears in contexts where it clearly refers to the service of distributing water and providing drainage facilities to recipients.” Barcellos, 899 F.2d at 823 n. 14 (emphasis added).

The price per acre-foot of water provision in Article 6(a) of the 1963 Contract confirms that “water or service” in Article 13 of the recordable contracts includes drainage service, because those two items were the predominant benefit of the bargain: $7.50/acre-foot for water, and $0.50/ acre-foot for drainage. By unambiguous terms within the 1963 Contract, a failure to provide drainage service implicates the Article 13 extension provision of the recordable contracts.

b. *1963 Contract*

Westlands and the government entered into the 1963 Contract on June 5, 1963, for the express purpose that the government provide CVP water to lands within West-lands’ boundaries for a forty-year term. See 1963 Contract ¶ 2. Article 3 separates the amount of water to be provided into three periods:

In each such period, the total volume of water that the United States must provide is reduced from the previous period, with the government’s performance obligation described as:

1963 Contract ¶ 3(a) (emphasis added). The 1963 Contract does not differentiate between excess and non-excess lands for the per acre-foot water price.

Only one contractual term explicitly sets the acre-foot61 price for water. Article 6(a) of the 1963 Contract provides that the annually-announced contract rate for water “may not be in excess of Eight Dollars ($8) per acre-foot and shall include a drainage service component of not to exceed

Fifty Cents ($0.50) ... and a water service component of not to exceed Seven Dollars and Fifty Cents ($7.50).”

In describing how Westlands will annually pay for water, e.g., half before January 1st, Article 6(b) specifically references paragraph 6(a) for the rate: “[t]he District shall make payments to the United States each year at the rate fixed as provided in subdivision (a) of this article.” 1963 Contract ¶ 6(b) (emphasis added). Article 5 limits Westlands’ water delivery to lands within the District without prior written consent.

Article 23(a) prevents Westlands from delivering water to any excess lands62 “unless the owners thereof shall have executed valid recordable contracts in form prescribed by the United States.” In Article 25(b)(i), as a “further condition precedent to the right to receive water made available pursuant to [the 1963] contract for any of his excess land,” each water-user in these recordable contracts:

“Each [water-user] entered into at least one such recordable contract with Interior between 1969 and 1974.” Barcellos, 899 F.2d at 816.

The 1963 Contract provides Westlands with water service for a specific annual volume at a $7.50/aere-foot water price and $0.50/acre-foot for drainage service. The Contract contains substantial detail about the maximum volume of water to be deliv- . ered in any year, and any reductions for water available from the Corcoran clay. See 1963 Contract ¶¶ 3(a)-(e). Only Article 6(a) enumerates the price for each acre-foot of water. Article 15 provides: “the payment of charges at the rate and upon the terms and conditions provided for herein is a prerequisite to the right to the use of water furnished to the District pursuant to this contract.”

c. Recordable Contract(s)

The prefatory recitals of the recordable contracts highlight that the landowners agreed to divest themselves of their excess lands “as an inducement to the United States to make water and distribution facilities available to the District for the excess land of the Landowner.”63 Under Article 5, “[a]ll rights of the Landowner to receive Project water for its excess land shall be subject to the provisions of the [1963] District Contract and this contract.” Article 8 of the recordable contracts limits the provision of water and service to excess lands under the terms of the 1963 Contract to times when the landowner owns the land, or sells it to a qualified “nonexcess landowner.”64

Article 11 of the recordable contracts mirrors the 1963 Contract’s ten-year divestiture provisions:

Article 13 of these recordable contracts reads:

The Barcellos opinion’s contractual interpretation must be reconsidered in light of the Ninth Circuit’s later interpretation of the 1963 Contract. Under federal common law, which includes the Uniform Commercial Code in O’Neill, 50 F.3d at 684 (citing Clem Perrin Marine Towing, Inc., 730 F.2d at 189 (“The Uniform Commercial Code is a source of federal common law”)), the contracting parties’ course of performance and dealing may be consulted to determine whether a contractual term is ambiguous, see id. (citing U.C.C. § 2-202). O’Neill found that the issue of interpretation of water-shortage provisions of the 1963 Contract, in light of Westlands’ contention that prorata allocation among all CVP contractors was required, could not be decided as a matter of law without remand for the taking of evidence. However, “[i]n no event may extrinsic evidence be employed to contradict explicit contract language or to drain an agreement’s text of all content save ink and paper.” Smart v. Gillette Co. Long-Term Disability Plan, 70 F.3d 173, 180 (1st Cir.1995) (citing Burnham v. Guardian Life Ins. Co. of Am., 873 F.2d 486, 489 (1st Cir.1989) (admonishing that “courts have no right to torture language in an attempt to force particular results or to convey delitescent nuances the contracting parties neither intended nor imagined.”)).

The Barcellos majority recognized the propriety of interpreting the 1963 Contract as a whole, see Barcellos, 899 F.2d at 821-25 (discussing different Articles of the 1963 Contract), but did not do so completely. The course of performance by the contracting parties, Interior and West-lands, aids interpretation of the 1963 Contract’s pricing term.

a. December, 1983: Interior Final Rule U(i)(k)

“Land under recordable contract which is held by a water user not subject to the discretionary provisions may continue to receive irrigation water at the contract rate for the extended term of the contract ....” 1983 WL 110969 (48 Fed.Reg. 54,-748; at 54,781 (Dec. 5, 1983)).65 Under this rule, for any extended term of a recordable contract, such excess land was eligible during the extended term to receive subsidized water. Even after the 1986 Barcellos Judgment, Interior retained Rule ll(i)(4) until 1987. See 1987 WL 129697 (52 Fed.Reg. 11,938; at 11,973 (Apr. 13, 1987)).66

b. December, 1986: Barcellos Consent Judgment

By paragraphs 8-9,67 the 1986 Consent Judgment refunded all water payments in excess of the $8.00/acre-foot contract rate made since June 30, 1978, the date of the Krulitz opinion, including payments for water used on excess lands. See also Bar-cellos, 899 F.2d at 819. Under the 1982 RRA, the government was not otherwise required to so do, because § 205(c) explicitly limited the right to receive subsidized water to ten years, regardless whether Article 13 extended the ten-years’ divestiture requirement. But see RRA § 203(b), 43 U.S.C. § 390ce(b) (2000) (omitting § 205(c) from list of RRA sections specifically applicable to recordable contracts executed prior to RRA’s effective date). In 1982, Congress, by RRA § 209(d), superseded the district court injunction against selling excess lands. Shortly after that time, excess land sales resumed, so Article 13 of the recordable contracts (if applicable) could no longer extend the ten-years’ ownership based on Interior’s failure to approve land sales. From 1982 (the RRA’s effective date) to 1986, the landowners still had extended time left on their ownership of the excess lands,68 but under RRA § 205(c), after eighteen months, they should no longer have received subsidized water.69 But they did.

The Senate apparently understood that the 1986 Barcellos Consent Judgment allowed water to continue to be delivered to excess lands at the $8.00/acre-foot rate for the “extended duration of the contract.” See, e.g., 132 Cong. Rec. S16575-01 (daily ed. Oct. 17, 1986) (statement of Sen. Proxmire) (“Under the [1986 Barcellos Consent Judgment] Westlands could violate the [1982 RRA limitation of subsidized water to only non-excess lands] for an additional 20 years.”); 132 Cong. Rec. E2762-01 (extension of remarks, Aug. 6, 1986) (Rep. Tony Coelho) (“[Under the 1986 Barcellos Consent Judgment] [t]he United States would agree to perform the water service contract that it has had with Westlands since 1963, a contract whose validity has not been challenged. This contract has been approved by the President, by Congress, and by the Court. This contract requires the United States to deliver 900,000 acre-feet of firm water supply at a rate of $7.50 per acre-foot plus the additional drainage service change [sic] of 50 cents per acre-foot.”); 132 Cong. Rec. E2711-01 (extension of remarks, Aug. 1, 1986) (Hon. Howard Wolpe) (“In direct violation of the 1982 Reclamation Reform Act, [the 1986 Barcellos Consent] settlement entitles a group of wealthy Westland agricultural interests to expanded water rights at a fraction of their actual cost.... The settlement not only releases West-lands from responsibility for [the Kester-son Wildlife Refuge] problem, but in fact encourages further such problems by increasing the amount of cheap water avail

able to the Westlands area.”) (emphasis added).

c. December, 1987: RRA § 224(h)

In December, 1987, Congress amended the RRA to add section 224(h), codified at 43 U.S.C. § 390ww(h), which applied § 205(c) to all recordable contracts executed prior to October 12, 1982, including the Contracts in dispute here. Section 205(c), part of the original RRA, limited the right to subsidized water to ten years from the date the recordable contract was originally executed, regardless whether the ownership period was extended by Article 13 of those recordable contracts (adding the eighteen-month grace period immediately following the resumption of land sales), and mandated “full cost” payment after that grace period.

The 1963 Contract in Article 3(a) provides that Westlands shall receive water at the contract rate for the duration of the Contract, until 2003 (40 years).70 The Contract specifies only one price for water — in Article 6(a): a ceiling of $8.00 (with $7.50 water and $0.50 drainage components). The 1963 Contract does not differentiate between the price per acre-foot for excess and non-excess lands, only requiring that the owner of the excess lands execute a recordable contract as a condition precedent to receiving water for those excess lands. There is no dispute that under the 1963 Contract, each landowner was entitled to subsidized water for excess lands during the initial ten-year period within which those excess lands had to be sold. The 1963 contract does not, on its face, absolutely limit the provision of subsidized water to excess lands to a maximum of ten years.

One interpretation now advanced is that the 1963 Contract is not ambiguous, and that the landowners are entitled to the contractual (subsidized) rate for water delivered to all their land as long as they own it, including excess lands during any extension period under Article 13, caused by a condition not their fault, e.g., the government’s failure to adequately provide drainage service.

Undisputed evidence of the contracting parties’ performance during the extension period while the D.C. district court injunction against excess land sales was in effect and afterwards proves:

(1) under Interior’s (one of the contracting parties) December, 1983-87 Rules (expressly revoked71 by Congress under RRA § 224(h)), water was delivered to excess lands during an extended period (lasting more than 20 years) at the 1963 Contract, not full-cost, rate; and

(2) the 1986 Barcellos Judgment refunded any “full cost” payments made for water delivered to excess lands during the extended period following the 1978 Krulitz opinion until December 30, 1986, the date of the Judgment.

The 1963 Contract is unambiguous with respect to water price: it sets the $8.00/acre-foot water and drainage-service rate in Article 6(a). No other contractual provision differentiates between excess and non-excess lands regarding water price, treating all land the same: “the United States shall furnish to the District,

and the District, each such year, shall accept and pay, as provided in Article 6 hereof, for water from the San Luis Unit .... ” The only prerequisite to receive San Luis Unit water for excess lands is Article 23(a)’s condition precedent that the landowner execute a recordable contract for any excess lands. Article 13 of the recordable contracts extends the ten-year ownership period during any time water or drainage service is not provided to the District’s lands through no fault of the District or a water-user. It is silent about the payment rate for water and service during an extension period.

The subsequent course of performance of the parties, as shown by both the 1986 Barcellos Judgment and Interior’s 1983 and 1987 Final Rules, is evidence that the parties, despite the political battle that raged in the Executive and Legislative branches, applied the 1963 Contract water rate uniformly to Westlands’ lands, including excess lands during any extended period: Article 8 of the 1986 Barcellos Judgment provides that the government would not seek full-cost reimbursement for any water delivered before 1986 (a twenty-three-year period), even to excess lands. Interior Final Rule ll(i)(4), promulgated during the extension period, provided that the excess lands “may continue to receive irrigation water at the contract rate for the extended term of the [recordable] contract.”

The action of a non-party, Congress, also supports the water-users’ interpretation, because if the 1963 Contract rate did not apply to the excess lands, there was no need for Congress to pass § 224(h) in 1987 to retrospectively apply § 205(c)’s full-cost requirement to those lands under recordable contracts. Rather, Interior could simply have collected full cost for water delivered to excess lands within Westlands. Section 224(h) was necessary to abrogate any right to subsidized water for excess lands beyond the ten-year period.

Last, this reading also comports with the contractual analysis doctrine that every contract should be read as a whole, with the preference against interpretations that are internally inconsistent. See Trident Ctr., 847 F.2d at 566. If no subsidized water were available for excess lands beginning ten years after the recordable contracts were signed, the bargained-for promise of ten years of subsidized water would be illusory: the government could conceivably refuse to provide any water to these lands for the first ten years, which would trigger Article 13’s ownership extension (because no water service was provided), but under an overly-broad reading of the 1990 Barcellos opinion, during that extended time, the landowner would have to pay full-cost for water. This is inconsistent with the interpretation of the contractual bargain for at least ten years of water and (drainage) service for excess lands at the subsidized rate. The same reasoning applies to lack of drainage service.72

The 1963 Contract and 1986 Barcellos Judgment give a protectable contractual right to $8.00/acre-foot water for the water-users’ excess lands during any Article 13 extension periods caused by the government’s failure, if any, to provide drainage service.

The analysis of what drainage service was actually provided and when, requires

factual development to ascertain whether a failure to provide drainage “service” occurred to extend the ten years under Article 13 of the recordable" contracts.

F. Impact of RRA section 22b(h)

The 1963 Contract’s water rate applies to excess lands during any extension period under Article 13 of the recordable contracts. “When the United States enters into contract relations, its rights and duties therein are governed generally by the law applicable to contracts between private individuals.” Mobil Oil Exploration, Producing S.E., Inc. v. United States, 530 U.S. 604, 120 S.Ct. 2423, 2429, 147 L.Ed.2d 528 (2000) (quoting Winstar, 518 U.S. at 895, 116 S.Ct. 2432).

The Ninth Circuit explicitly held that “Section 224(h) clearly applies” to the water-users. Barcellos, 899 F.2d at 820.73 This holding is law of the case. In Barcellos, the Court found there was no contract right to subsidized water for more than ten (10) years, because Article 13 “service” did not encompass Interior’s approval of land sales.

In this case by contrast, an Article 13 extension may operate, once the disputed factual determination is made what “drainage service” means for the purposes of extension of the ten-year period. Fire-baugh establishes “drainage service” has not been provided, at least since 1986. This does not end the inquiry.

RRA § 224(h), in combination with RRA §§ 205(a)-(c), abrogate the contractual right to receive CVP water at the 1963 Contract water and drainage-service price, as interpreted by the 1986 Judgment (¶ 4), because together those RRA sections mandate, as of § 224(h)’s effective date, December 22, 1987, that the Bureau charge the “full cost” rate for water to excess lands, not the contractual $8.00/acre-foot rate, and revoke Interior’s rules to the contrary. See 43 U.S.C. §§ 390ee(a)-(e); 390ww(h) (2000). This abridgement of a U.S. government contractual right requires analysis of the unmistakability and sovereign acts defenses.

*3.Government Defenses: Unmistaka-bility and Sovereign Acts Doctrines*

The government argues that even if a contractual right to the subsidized water rate for excess lands during any Article 13 extension periods caused by the failure to provide drainage existed under the 1963 Contract, it is nevertheless excused from any breach caused by § 224(h)’s full-cost requirement, based upon Congress’ sovereign power to legislate.

“[P]unctilious fulfillment of contractual obligations is essential to the maintenance of the credit of public as well as private debtors.” Winstar, 518 U.S. at 885 & n. 29, 116 S.Ct. 2432 (citing Lynch v. United States, 292 U.S. 571, 580, 54 S.Ct. 840, 78 L.Ed. 1434 (1934) (Brandéis, J.); Kyle D. Logue, Tax Transitions, Opportunistic Retroactivity, and the Benefits of Government Precommitment, 94 MICH. L. REV. 1129, 1146 (1996) (“If we allowed the government to break its contractual promises without having to pay compensation, such a policy would come at a high cost in terms of increased default premiums in future government contracts and increased disenchantment with the govern

ment generally.”) (citing Richaed A. Pos-ner, Eoonomic Analysis of Law 81 (3d ed.1986))). “The United States are as much bound by their contracts as are individuals. If they repudiate their obligations, it is as much repudiation, with all the wrong and reproach that term implies, as it would be if the repudiator had been a State or a municipality or a citizen.” Lynch, 292 U.S. at 580, 54 S.Ct. 840 (quoting Central Pac. R.R. Co. v. United States (The Sinking Fund Cases), 99 U.S. 700, 719, 9 Otto 700, 25 L.Ed. 496 (1878)). Another reason the government should be held to its contractual promises “is to serve ‘the Government’s own long-run interest as a reliable contracting partner in the myriad workaday transactions [sic] of its agencies.’ ” Bellevue Manor Assocs. v. United States, 165 F.3d 1249, 1253 n. 3 (9th Cir.1999) (quoting Winstar, 518 U.S. at 883, 116 S.Ct. 2432 (Souter, J.)) (misquote in original); see also Madera Irrigation Dist. v. Hancock, 985 F.2d 1397, 1401 (9th Cir.1993) (“But too liberal an interpretation of the residual sovereign power of the government to override its contractual commitments would eviscerate the government’s power to bind itself to contracts. In addition to the moral offensiveness of allowing the government to break its promises, too liberal a construction would have the paradoxical consequence of weakening the sovereign power to implement policy.”) (citing Perry v. United States, 294 U.S. 330, 351-54, 55 S.Ct. 432, 79 L.Ed. 912 (1935)).74

a. Unmistakability doctrine

“The Unmistakability Doctrine provides that contracts limiting the government’s future exercise of regulatory authority must be expressed in unmistakable terms.” Far W. Fed. Bank v. Office of Thrift Supervision-Dir., 119 F.3d 1358, 1365 n. 3 (9th Cir.1997) (citing Winstar, 518 U.S. at 872, 116 S.Ct. 2432 (“Sovereign power governs all contracts subject to the sovereign’s jurisdiction, and will remain intact unless surrendered in unmistakable terms.”) (quoting Bowen v. Pub. Agencies Opposed to Soc. Sec. Entrapment, 477 U.S. 41, 52, 106 S.Ct. 2390, 91 L.Ed.2d 35 (1986) (quoting Merrion v. Jicarilla Apache Tribe, 455 U.S. 130, 148, 102 S.Ct. 894, 71 L.Ed.2d 21 (1982) (quoting St. Louis v. United R. Co., 210 U.S. 266, 280, 28 S.Ct. 630, 52 L.Ed. 1054 (1908))))) (alteration, internal quotation marks, and ellipsis omitted). What the standard is remains unclear: “Courts have struggled with the meaning of Winstar.” Pitney Bowes Inc. v. United States Postal Serv., 27 F.Supp.2d 15, 23 (D.D.C.1998) (applying Winstar to hold the unmistakability doctrine did not shield the government when it passed regulations that ceased allowing the plaintiffs to keep interest on specified funds) (quoting Tamarind Resort Assocs. v. Gov’t of the Virgin Islands, 138 F.3d 107, 112 (3d Cir.1998) (citing Yankee Atomic Elec. Co. v. United States, 112 F.3d 1569, 1578-79 (Fed.Cir.1997))). Winstar examined “contracts” between’the Federal Home Loan Bank Board and thrifts that allowed these healthy thrifts to acquire failing thrifts and count as “supervisory goodwill” the difference between the purchase price and the fair market value of all the identifiable assets of the acquired thrift. See Winstar, 518 U.S. at 845-50, 116 S.Ct. 2432. The reason for this treatment was to induce purchase of these failing thrifts, because the Federal

Savings and Loan Insurance Corporation lacked the funds to liquidate the failing thrifts itself. See id. at 847, 116 S.Ct. 2432; 849-50 (“Recognition of goodwill under the purchase method was essential to supervisory merger transactions of the type at issue in this case.”). Under special accounting practices, this supervisory goodwill could be counted towards meeting the reserve capital requirements imposed by federal regulations. See id. at 848, 116 S.Ct. 2432 (citing Congressional testimony).

However, Congress passed the Financial Institutions Reform, Recovery, and Enforcement Act of 1989 (“FIRREA”), Pub.L. 101-73, 103 Stat. 183, which, inter alia, phased out by 1985 the ability of thrifts to count supervisory goodwill as part of their reserves. See id. at 856-57, 116 S.Ct. 2432. As a result of FIRREA’s new capital requirements, “many institutions [including the Winstar plaintiffs] immediately fell out of compliance with regulatory capital requirements, making them subject to seizure by thrift regulators.” Id. at 857-58, 116 S.Ct. 2432 (citing William K. Black, Ending Our Forebearers’ Forbearances: FIRREA and Supervisory Goodwill, 2 STAN. L. & POL’Y REV. 102, 107 (1990)).

The plaintiffs acquired failed thrifts before the enactment of FIRREA, thrifts that federal regulators thereafter seized and liquidated for failure to meet FIR-REA’s new capital reserve requirements, which limited the ability to include “supervisory goodwill.” See id. at 858, 116 S.Ct. 2432. Because they believed that the Bank Board had promised them that they could continue to count the supervisory goodwill towards the required capital requirements, plaintiffs sued the United States for damages based on contractual and constitutional theories of recovery. See id. The Supreme Court in a plurality decision rejected the government’s proffered defenses of the unmistakability and sovereign acts doctrines, affirming the lower courts’ findings of liability against the government for breaching its “contractual” promise with these thrifts to continue to allow them to count supervisory goodwill as part of their required reserves.

One formulation of the unmistakability doctrine is that it applies only when “enforcement of the contractual obligation alleged would block the exercise of a sovereign power of the Government.” Id. at 879, 116 S.Ct. 2432 (Souter, J.).75 Justice Souter, in his plurality opinion, gave two examples at differing ends of the “wide spectrum” of contracts protected and not protected by the unmistakability doctrine: “humdrum supply contracts” (not protected) versus “a claim for rebate under an agreement for a tax exemption” (protected, because “[gjranting a rebate, like enjoining enforcement, would simply block the exercise of the taxing power.”) Id. If the unmistakability doctrine applies; whichever version, no breach of contract claim based on subsequent Congressional action lies against the government, unless the contract expressly contains limitations (an unmistakable waiver) against future regulatory authority.76

Although seven Justices formed the majority to support the .Winstar unmistaka-

bility judgment (i.e., that it did not shield the government from liability), there was not a majority opinion, and the four separate opinions77 are thoroughly fragmented, not articulating any unified analysis in support of the judgment based on either the unmistakability or sovereign acts doctrines.

Five Justices disagreed with the conclusion that the unmistakability doctrine was not available simply because the contracts were risk-shifting agreements. However, three of them, Justices Scalia, Thomas, and Kennedy, nevertheless concurred in the judgment, because they interpreted the government’s actions as conveying an unmistakable promise to continue the favorable regulatory treatment. See Winstar, 518 U.S. at 920-22, 116 S.Ct. 2432 (Scalia, J., concurring in the judgment). The breakdown is:

As a result of these shifting positions, it appears particularly problematic to predict which unmistakability standard applies to any specific contract.

Unfortunately, but not unsurprisingly, given the Supreme Court opinion, the few cases applying the unmistakability doctrine after Winstar (most from the Federal Circuit) also diverge in their formulation and interpretation of the doctrine. For example, in Yankee Atomic Electric Co.79 the Federal Circuit applied Winstar to hold that the government’s imposition of special assessments for clean-up of former uranium enrichment plants under a Congressional Act80 did not violate any rights of the plaintiffs, who were nuclear power plants owners that had fully performed contracts with the United States for the purchase of uranium at fixed prices. These plaintiffs argued that by assessing them for cleanup costs for past use of the uranium, the government had in essence retroactively increased the price they must pay for that uranium, a price that was firmly set in their contracts. The court’s conclusion that the unmistakability doctrine nevertheless shielded the government from liability in this situation rests on its finding that the Act was “a general exercise of Congress’s taxing power for the purpose of addressing a societal problem rather than an act that retroactively increases the price charged to contracting parties for uranium enrichment services.” Id. at 1577. This panel rejected the (apparent) five-justice majority holding that the unmistakability doctrine applies regardless of the nature of the underlying contract, see id. at 1579,81 and instead applied a different Winstar holding (probably only supported by four Justices — the Souter view) that “application of the unmistak-ability doctrine turns on whether the enforcement of the contractual obligation would effectively block the exercise of a sovereign power of the Government,” id. at 1579 (quoting Winstar, 518 U.S. at 879 (Souter, J.)). Because the special assessment at issue implicated the sovereign power of taxing authority, the Court found that the unmistakability doctrine applied. See id.82 Last, the panel applied the six-Justice majority holding that demands that the government make an unmistakable “second promise” not to subsequently exercise its sovereign power to act in the challenged manner, or the unmistakability doctrine insulates it from contractual liability. See id. at 1579-80. The Court finally found that “the fixed-price terms of the contract do not constitute an unmistakable promise on behalf of the Government that it will not impose a general assessment [for cleanup] upon all utility companies that benefitted from the DOE’s uranium enrichment services,” id. at 1580, so the unmistakability doctrine insulated the government.

In Adams v. United States,83 the unmis-takability defense applied to insulate the government against breach of contract

claims by rental housing project owners who had loan agreements/contracts with the Farmers Home Administration (“FmHA”) that gave them prepayment terms, which were impaired by subsequent Congressional action. Unlike the previous case, the Adams panel applied the five-justice (Justice Scalia concurrence (3) and Justice Rehnquist dissent (2)) majority’s reasoning that “the unmistakability doctrine applies even if the contract can be reasonably construed as a risk-shifting agreement and the enforcement of the agreement would not effectively bar the exercise of a sovereign power.” Id. at 482 (citing Winstar, 518 U.S. at 919, 116 S.Ct. 2432 (Scalia, J.)). It found that the mortgage agreements did not have the second promise to “guarantee the prepayment option against future acts of Congress,” so the unmistakability defense applied. See id. at 483-84. However, this conclusion may be driven by two additional considerations touched upon by the court: (1) the mortgage agreements made the contract terms “subject only to ‘FmHA’s future regulations not inconsistent with the express provisions hereof.’ No such commitment regarding possible statutory enactments appears in the language of the lpan and mortgage documents, and future regulations of FmHA are not synonymous with future acts of Congress,” id. at 484; and (2) “the prepayment options included in varying terms in the plaintiffs’ contracts have not been demonstrated by the plaintiffs before this court to be ‘essential to the contract between the parties,’ ” id. at 485 (quoting Winstar, 518 U.S. at 909, 116 S.Ct. 2432). The court seems to adopt the six-Justice majority holding that a specific “second promise” must be made in order to overcome the unmistakability defense, and also the three-Justice non-majority holding that the legislated-over contractual term must .be “essential” to the contract for the government to breach the contract and seek the unmistakability defense.

Barsebáck Kraft AB v. United States84 rejects a breach of contract claim against the government based on a change in the method it used to calculate the price for uranium enrichment services provided under contracts it held with plaintiffs. The court distinguished Winstar because the contract at issue in Barsebáck Kraft AB stated “the charges to be paid to DOE for enrichment services provided to the Customer hereunder will be determined in accordance with the established DOE pricing policy for such services,” which was defined in the contract as “any policy established by DOE that is applicable to prices or charges in effect at the time of performance of any services under this contract,” id. at 1477-78 (quoting contract articles), thereby placing the risk on the plaintiffs, see id. at 1481 (“this case is the other side of the Winstar coin.”). The Barsebáck contract specifically provided the contract provisions were subject to subsequent legislative changes by the pricing language: “any policy” applicable to prices or charges in effect at the time the uranium enrichment services were performed. The court concluded that no contractual promise had been broken and found it unnecessary to reach the unmis-takability defense.

In 2000, General Dynamics Corp. combined the unmistakability doctrine with the sovereign acts doctrine (discussed infra) by imputing the requirement that the purported sovereign act be “public and general” in order for the unmistakability doctrine to apply. See Gen. Dynamics Corp., 47 Fed. Cl. at 545.

Most recently, Schism v. United States85 appears to reformulate the unmis-

takability doctrine: “the terms of a government contract, like any other contract, do not change with the enactment of subsequent legislation, absent a specific contractual provision providing for such a change.” Id. at 1290 (citing Winstar, 518 U.S. at 889, 116 S.Ct. 2432). There, the court held that the United States breached its “contract” with veterans by requiring them to rely on Medicare health benefits when they turned 65, rather than providing the free “lifetime medical care” from the military that the recruiters had promised in order to induce them to initially enlist and serve at least twenty years. Aside from quoting language from Wins-tar regarding the federal government’s duty to not avoid its contractual obligations by subsequent legislation, the court did not apply any unmistakability doctrine requirements, but rather simply held that government lacked power to divest the servicemen’s contractual rights to medical care, even though- it enacted laws that purported to so do. See id. at 1290-91. This decision seems to depart from Winstar’s five-Justice majority holding that the unmistakability doctrine applies unless a second unmistakable promise is made, and instead holds that if the contract in question does not make itself subject to future legislation, then it is immune.

Unmistakability analysis has been applied to include at least four discrete components: (1) existing contractual right;86 (2) impairment of that right; (3) implication of a sovereign power (arguably); and (4) unmistakable waiver of sovereign authority within the contract, ie., second promise (or at least Justice Scalia’s application of the reverse presumption).

Here, the first requirement is met: the 1963 Contract contains a right to a $7.50/aere-foot water and $0.50/acre-foot drainage-service rate for excess lands during Article 13 ownership extension periods caused by lack of water or drainage service. Subsequent legislation, RRA sections 205(c) and 224(h), impair that right, because they increase the cost to “full cost” payment for water delivered to excess lands.87

The difficult question is whether a sovereign power is implicated. Winstar’s divergent holdings may vitiate this requirement, ie., Justices Rehnquist and Ginsburg clearly write that the doctrine applies to all government contracts, and Justices Scalia, Kennedy, and Thomas question the necessity of a sovereign power implication requirement, see id. at 919, 116 S.Ct. 2432.

Sections 205(c) and 224(h) require only that a higher price (“full cost”) be charged for governmental resources: water and drainage service. The 1963 Contract is analogous to the example given by Justice Souter in Winstar of a contract to which the unmistakability doctrine does not apply, e.g., a supply contract for procuring food for the army.88 But see Winstar Corp., 518 U.S. at 919-20, 925-36, 116 S.Ct. 2432 (possibly five votes for applying doctrine to any contracts with the government). For example, if the government entered a contract with a food wholesaler to sell beans to that party at $x/lb. for 20 years, and during the contract term passed legislation that required that all federally-supplied beans must be sold at no less than “full cost,” $(x+l)/lb., the government could not shield itself from its contractual obligation by application of the unmistakability doctrine, because a bean-supply contract does not implicate a sovereign power. So too here. Charging “full cost” for all water implicates a water-pricing term in a water-delivery contract, but does not implicate a sovereign power, even if navigation of waterways may. This is a contract for delivery of a commodity (water) and service (drainage). Section 224(h) seeks to override the contract and raise the water price.

Where no sovereign power is implicated under the 1963 Contract or the 1986 Bar-cellos Judgment, it is unnecessary to determine whether the government unmistakably waived its power to legislate as to those contracts. A parity of reasoning applies to rebut the Justice Scalia reverse presumption, because the “essential” term of the 1963 Contract is the pricing per acre-foot for water and drainage service.

The unmistakability doctrine does not insulate the government from performing the water-pricing terms of the 1963 Contract, the recordable contracts, and the 1986 Barcellos Judgment.

b. Sovereign Acts doctrine

“The Sovereign Acts doctrine provides that government as contractor cannot be held liable for the acts of government as regulator.” Far W. Fed. Bank, 119 F.3d at 1365 n. 3. The sovereign acts doctrine shields the government from breach of contract liability when it undertakes “public and general” acts that have the incidental effect of modifying contracts it has with private persons. See Winstar, 518 U.S. at 891-94, 116 S.Ct. 2432. “A governmental act will not be public and general if it has the substantial effect of releasing the Government from its contractual obligations.” Gen. Dynamics Corp., 47 Fed. Cl. at 541 (quoting id. at 899, 116 S.Ct. 2432). Even if the government shows that the act is “public and general,” it must also “show that the passage of the statute rendering its performance impossible was an event contrary to the basic assumptions on which the parties agreed ....” Winstar, 518 U.S. at 904, 116 S.Ct. 2432 (analogizing to the impossibility de

fense for breach of contract). “In Wins-tar, the plurality explained that the doctrine is designed to distinguish between the Government’s twin roles as contractor and sovereign.” Yankee Atomic Elec. Co., 112 F.3d at 1574-75 (citing Winstar, 518 U.S. at 892, 116 S.Ct. 2432 (quoting Horowitz v. United States, 267 U.S. 458, 461, 45 S.Ct. 344, 69 L.Ed. 736 (1925))). “The Government-as-contractor cannot exercise the power of its twin, the Government-as-sovereign, for the purpose of altering, modifying, obstructing or violating the particular contracts into which it had entered with private parties.” Id.

As with the unmistakability doctrine, no consensus regarding the sovereign acts doctrine exists under Winstar. Justice O’Connor did not join Justice Souter’s plurality addressing the “public and general” requirement for applicability of the sovereign acts doctrine (Sections TV-A and B), nor did she write separately on the point. Justice Ginsburg joined the Rehnquist dissent, but not the part of his dissent addressing the sovereign acts doctrine (Part III), failed to join any other opinion, and did not write separately on the sovereign acts doctrine. What Winstar leaves is a 3-1 splintering (Justices Souter, Stevens, and Breyer versus Justice Rehnquist) in favor of the “public and general” requirement for application of the sovereign acts defense. In the minority, Justice Rehnquist applies the sovereign acts defense to relieve the government from contractual liability whenever its legislative act has a general “regulatory” purpose, regardless whether a significant impact of that action relieves the government of its contractual obligations. See id. at 933-34, 116 S.Ct. 2432 (Rehnquist, J., dissenting). The last three Justices, Scalia, Kennedy, and Thomas, believe “the ‘sovereign acts’ doctrine adds little, if anything at all, to the ‘unmistakability’ doctrine, and is avoided whenever that one would be .... ” Id. at 923, 116 S.Ct. 2432 (Scalia, J., concurring in the judgment).

In Scott Timber Co. v. United States,89 a timber contractor brought suit contending the government breached timber sales contracts when it suspended them from logging in order to protect the marbled murrelet,90 prompted by a TRO issued by a district court that prohibited the logging on any habitat of the threatened species. See id. at 172-73. The court applied the (Souter three-Justice) sovereign acts doctrine, which it found consisted of two prongs:

ing party in a contract action, must show that the sovereign act rendering its performance impossible was an event contrary to the basic assumption of the parties.” Put differently, to satisfy the second prong of the sovereign acts defense, the government must show that the “nonoccurrence of the sovereign act was a basic assumption of the contract.”

Scott Timber Co., 40 Fed. Cl. at 507-08 (internal quotations and alteration marks omitted). There, the government could not satisfy the second prong, because the contracts themselves anticipated that additional species would be added to the list of endangered or threatened species, and thus, the government could not show that the non-occurrence of the listing was a basic assumption of the contract. See id. at 508.

Here, applying the first step of the three-Justice version of the sovereign acts doctrine, as did Scott Timber Co., the government cannot meet the first prong: a public and general requirement (or even Justice Rehnquist’s regulatory construct). The 1963 Contract has a singular overriding purpose: the government supplies a specified volume of water (and drainage service) to Westlands at a subsidized price ($8.00/acre-foot) over a defined time period (40 years). Section 224(h) raises the acre-foot water price to “full cost,” specifically targeting Westlands and recordable contract contractors with low, fixed-rate water contracts, arising from the legislators’ concern with over-subsidizing “rich corporations and large farmers.” See, e.g. 133 Cong. Rec. E4995-02 (extension of remarks, Dec. 22, 1987) (statement of Rep. George Miller); 133 Cong. Rec. E335-01 (extension of remarks, Feb. 3, 1987) (statement of Rep. George Miller); H.R. Conf. Rep. No. 495, 100th Cong., 2d Sess. 786.91

There is no “broader governmental objective” to RRA § 224(h), other than to target contractors who had contractual promises for a (low) fixed price per acre-foot for CVP water. The RRA provision is not public and general, because its impact on the 1963 Contract is not “merely incidental” to, e.g., some broader regulatory scheme. See, e.g., Adams, 42 Fed. Cl. at 478-80 (“Applying the defense in such a situation would improperly grant the government carte blanche to avoid liability for any contractual commitment to its citizens merely by enacting legislation repudiating the commitment. Assuredly, no private party has that luxury.”). The sovereign acts defense does not apply.

c. Effect of Article 26 of the 1963 Contract

Article 26 of the 1963 Contract92 provides in material part: “... in the event that the Congress amends the excess-land provisions or other provisions of the Federal reclamation laws, the United States agrees, at the option of the District, to negotiate amendments of appropriate articles of this contract, all consistently with the provisions of such repeal or amendment.” The amendments to the federal reclamation laws after 1963 gave the District the option to negotiate amendments of appropriate articles of the 1963 Contract, consistent with the provisions of such amendments. Assuming that the addition of § 224(h) was such an amendment of the federal reclamation laws, negotiations by the District were unsuccessful to retain the contract price for water service furnished during any period of extension to the excess lands under recordable contracts. Although unnecessary to the analysis for reasons stated above, Article 26 is an express reservation of authority to

amend the federal reclamation laws, not a waiver of-the sovereign power to do so. See, e.g., Westlands Water Dist., 850 F.Supp. at 1406-07 (rejecting that Article 23 was an unmistakable waiver of sovereign power to legislate) (citing Peterson, 890 F.2d at 812).

d. Conclusion

RRA section 224(h) abridges the contractual right to subsidized water for excess lands during any Article 13 extension period caused by the government’s failure to provide water or drainage service. Neither the unmistakability doctrine nor the sovereign acts doctrine shields the government from the breach caused by section 224(h).

G. . Jurisdiction over the Unjust Enrichment Counter-Claim

The Government argues summary judgment is appropriate, claiming that regardless whether the counter-claims for restitution for drainage-component payments are legally sufficient, there is nevertheless no independent waiver of sovereign immunity that allows the water-users to bring an unjust enrichment counterclaim to recover the drainage component previously paid by water-users to Westlands for the government. See Doc. 327 at 2.

“The United States, as the sovereign, is immune from suit unless express permission to sue it has been granted by Congress.” 6 ChaRles Alan Wright, Arthur R. Miller, & Mary Kay Kane, Federal PraCtioe and Procedure § 1427, at 194 (3d ed.1990) (footnote omitted). “When sovereign immunity is at issue, the government is immune from a suit, whether couched as an original claim or as a counter claim, unless it has waived its immunity.” United States v. $277,000 U.S. Currency, 69 F.3d 1491, 1493 (9th Cir.1995) (citing United States v. Lockheed L-188 Aircraft, 656 F.2d 390 (9th Cir.1979)). That the Government brought this suit is of no consequence: “there is no ‘implied waiver’ of sovereign immunity as to counterclaims based on the government’s commencement of an action.” Presidential Gardens Assocs. v. United States, 175 F.Sd 132, 140 (2d Cir.1999).

The cases cited by the water-users are not to the contrary. In both Northern Cheyenne Tribe v. Lujan, 804 F.Supp. 1281 (D.Mont.1991), and A.T.C. Petroleum, Inc. v. Sanders, 860 F.2d 1104, 1113 (D.C.Cir.1988), private parties sued the United States under unjust enrichment theories. In each case, there was an independent waiver of sovereign immunity.93 See A.T.C. Petroleum,, Inc., 860 F.2d at 1113 (discussing the Small Business Association, for which Congress has expressly waived sovereign immunity); N. Cheyenne Tribe, 804 F.Supp. at 1288 (“Where a fed

eral common law claim seeking equitable relief is coupled with a tvaiver of sovereign immunity... federal district courts have original jurisdiction to hear such claims.”) (citing cases) (emphasis added).

This rule is, however, subject to one very narrow exception: where a party seeks simply to offset the amount of the sovereign’s recovery. See Presidential Gardens Assocs., 175 F.3d at 140 (citing United States v. Forma, 42 F.3d 759, 764 (2d Cir.1994)). “As the Ninth Circuit has put it, though ‘a suit in the name of the United States does not amount to a waiver of sovereign immunity subjecting the United States to an affirmative adverse judgment on a counterclaim, the counterclaim may be asserted against a sovereign by way of set off or recoupment to defeat or diminish the sovereign’s recovery.’ ” Forma, 42 F.3d at 764 (quoting United States v. Agnew, 423 F.2d 513, 514 (9th Cir.1970)) (citing other sources) (alteration marks and ellipsis omitted); see also 6 Charles Alan Wright, AethuR R. Miller, & Mary Kay Kane, Federal Practice and Procedure § 1427, at 197 (3d ed. 1990) (“Despite the sovereign immunity doctrine ..., when the United States institutes an action, [a] defendant may assert by way of recoupment any claim arising out of the same transaction or occurrence as the original claim in order to reduce or defeat the government’s recovery.”) (citing cases).94

The water-users’ allegation that the United States is not entitled to retain the monies collected by Westlands for the drainage-service component of the per-acre-foot water rate is in substance based on offset. The government argues that the water-users owe the difference between the full cost rate for excess lands and the contractual rate that the water-users paid. The water-users rejoin that they paid for drainage as a component of the per acre-foot water payments and did not receive drainage, entitling them to return of those funds under an unjust enrichment counterclaim. See, e.g., 1 B.E. Within, Summary of California Law (Contracts) § 91, at 122 (9th ed. 1987) (“When one obtains a benefit which he may not justly retain, he is unjustly enriched. ... [Unjust enrichment] is designed to restore the aggrieved party to his former position by return of the thing or its equivalent in money.”) (quoting sources).

The water-users assert an offset counterclaim; to the extent any funds are due them for the absence of drainage service, that amount may decrease any amount they owe for water-service payments less than the full-cost rate.95 Under Presidential Gardens Assocs. ’s offset (recoupment) exception to sovereign immunity, jurisdiction exists to hear the water-users’ counterclaim for unjust enrichment premised on not receiving drainage service.96

This case is distinguishable from Orff’s jurisdictional analysis. There, water-users sought to directly enforce, as intended third-party beneficiaries, Westlands’ contractual rights under its water-service agreement with Interior. See Orff v. United States, CIV-F-93-5217 (April 12, 2000) (Orff Doc. 634). Westlands was not a party and did not seek enforcement of the contract. Here, Westlands, the contractor, has interpled all water-service and drainage assessments for the disputed period. The water-users are real parties-in-interest against the United States in the dis-puté over their entitlement to funds they paid under direct contract with the government, which are deposited with the court. No one else is willing to litigate these claims on them behalf. A res in the form of money held by the court, over which there is an entitlement dispute, is a different and independent basis for jurisdiction. See, e.g., Miranne v. First Fin. Bank, F.S.B. (In re Miranne), 87 B.R. 897, 902 (E.D.La.1988) (retaining jurisdiction over funds in its registry, even though bankruptcy case had been dismissed).

The recordable contracts of each water-user are direct contracts with the United States, which require interpretation and a declaration of rights and duties to resolve who is entitled to the funds each water-user has paid to Westlands for the United States and are held by the court.97 The money on deposit in this case provides another basis for jurisdiction. Independent jurisdiction exists; this case is not governed by Orff.

H. Prematurity of Unjust Enrichment Claim

Despite the age of this litigation, the unjust enrichment claim is inchoate. In Firebaugh Canal Co., the Court of Appeals ordered the Bureau of Reclamation, on remand, to promptly take action to provide Westlands with drainage service, although not necessarily by construction of an interceptor drain as described in the San Luis Act. Rather, deference has been extended to the reasonable discretion of Interior to choose an alternative means of drainage. See Firebaugh Canal Co., 203 F.3d at 577-78 (“subsequent Congressional action supplements the drainage solutions available to the Department of the Interior.”) (citing two out-of-circuit cases and one 1979 Ninth Circuit case). The government provided some drainage until 1986. See id. at 571-

72. It expended over fifty million dollars ($50,000,000) studying “solutions to” the drainage problem. See id. at 578. Whether such activities constitute drainage “service,” and if so, to what extent such “drainage service” can be quantified in monetary terms; and to what extent the government’s drainage-service obligation may be satisfied, present mixed questions of law and fact, focused on a quantitative analysis of the value of, and qualitative analysis of the efficacy in statutory terms of, whether the Bureau’s efforts since 1986 fit within the statutory meaning of such drainage service. What the Government will actually do to implement its immediate statutory drainage obligation has not been revealed, although that time is now at hand. See, e.g., id.

Drainage, encompassing a physical drain or an alternative, cannot be provided without funding. It may be that if the drainage component funds paid by, inter alia, the water-users are used to provide for drainage service to comply with the Fire-baugh Canal Co. mandate, the Government is not unjustly enriched, because it will not have impermissibly retained the drainage monies.98

A separate issue concerning the appropriate remedy arises under Article 28 of the 1963 Contract. Article 28 provides in material part:

1963 Contract ¶ 28 (emphasis added).

The question that is presented by Article 28’s release from liability to the United States for failing to appropriate or allot funds to engage in “the performance of any work” under the 1963 Contract has not been fully considered in this litigation. NOTICE IS GIVEN THAT AS PART OF ANY FUTURE PROCEEDINGS OVER THE NATURE AND EXTENT OF RECOVERY, THE MEANING AND EFFECT OF ARTICLE 28 MUST BE ADDRESSED.

The water-users’ motion for summary judgment under a theory of unjust enrichment is premature; it must await determination on remand in Firebaugh Canal Co. or here, of the value of any drainage “service” previously provided or to be provided to the water-users.

The watei'-users’ and Interior’s course of performance, under the 1986 Barcellos Judgment and the 1963 Contract’s four corners, is evidence that they interpret the 1963 Contract in a manner consistent with the reasonable interpretation of its language: that the $8.00/acre-foot contractual rate applies to excess lands during any extension period under Article 13, if drainage service was not provided for at least ten years to lands under recordable contract. A failure to provide drainage service is an Article 13 cause for extension. However, if the evidence establishes that following 1963, the water-users received a total of ten years of water and drainage service for their excess lands under recordable contract, then no contractual right to continued subsidized water for excess lands exists, because the benefit of the bargain under the 1963 Contract has been received.

In December 1987, RRA section 224(h) abrogated the contract price by mandating full-cost payment for San Luis water service. The unmistakability defense does not apply, because § 224(h) does not implicate any sovereign power, and if it did, the explicit price and time terms in the contract suffice to rebut the reverse presumption. The sovereign acts defense does not apply because § 224(h) is not a “public and general” statute (nor even regulatory in nature), but rather, was specifically enacted to target less than full-cost pricing in federal water contracts. This is evident from the legislative history, which refers to the 1963 Contract’s fixed, low-cost rates for federal reclamation water and drainage service.

Factual issues, inter alia, remain: (1) what is the extent and value of any failure to provide drainage service; (2) what is the effect of Article 28 of the 1963 Contract on any remedy sought; (3) whether the United States is unjustly enriched by-retaining the water-users’ payments for drainage service and facilities; (4) when and for what time was any Article 13 extension applicable to water service for any landowners’ excess lands under recordable contract; and (5) to whom does the interest on the interpled fund belong. These issues cannot be resolved without further evidentiary proceedings. For the foregoing reasons, IT IS HEREBY ORDERED:

SO ORDERED.
