Here, the situation is somewhat different. The Loves allege that the government breached its obligation to deal with them fairly and in good faith. Montana law recognizes an extracontractual “implied covenant of good faith and fair dealing.” E.g., Nicholson v. United Pacific Ins. Co., 219 Mont. 32, 710 P.2d 1342, 1348 (1985); First Nat’l Bank in Libby v. Twombly, 213 Mont. 66, 689 P.2d 1226, 1230 (1984). Although this duty arises between parties having a contractual relationship, “the duty exists apart from, and in addition to, any terms agreed to by the parties_ The duty is imposed by operation of law and therefore its breach should find a remedy in tort.” Gates v. Life of Montana Ins. Co., 205 Mont. 304, 668 P.2d 213, 214-15 (1983). Thus, for example, the Montana courts have held that breach of the duty of good faith can support a punitive damages claim because it is an “action for breach of an obligation not arising from contract.” Id. (emphasis in original) (construing Mont.Code Ann. § 27-1-221). The duty of good faith not only arises from a source outside of the contract, but it also is breached by “some impermissible activity” beyond the mere existence of a breach of contract:
Historically, a party to a contract generally had the right to breach and pay damages rather than perform.... But whether performing or breaching, each party has a justifiable expectation that the other will act as a reasonable person. The nature and extent of an implied covenant of good faith and fair dealing is measured in a particular contract by the justifiable expectations of the parties. When one party acts arbitrarily, capriciously or unreasonably, that conduct exceeds the justifiable expectations of the second party. The second party then should be compensated for damages resulting from the other’s culpable conduct.
Nicholson v. United Pacific Ins. Co., 710 P.2d at 1348. In sum, the breach of the duty of good faith alleged here, as interpreted by the Montana courts, is a separate tort and is not, as was the case in Wood-bury, “based entirely upon breach by the government of a promise made by it in a contract.” 313 F.2d at 295 (emphasis added).
We conclude that breach of the duty of good faith is a tort properly brought under the FTCA. Our conclusion is bolstered by the apparent fact that the breach of this duty is not cognizable under the Tucker Act. The Court of Claims has jurisdiction over claims for money damages in excess of $10,000 “in cases not sounding in tort.” 28 U.S.C. §§ 1346(a)(2), 1491(a)(1). To the extent that this breach sounds in tort, it is expressly excluded by § 1491. Moreover, even if the breach of the implied covenant of good faith were cast as contractual, it would nevertheless appear that the Court of Claims lacks jurisdiction to decide such a claim, because the Tucker Act “does not reach claims based on contracts implied in law, as opposed to those implied in fact.” United States v. Mitchell, 463 U.S. 206, 218, 103 S.Ct. 2961, 2969, 77 L.Ed.2d 580 (1983); accord Hatzlachh Supply Co. v. United States, 444 U.S. 460, 465 n. 5, 100 S.Ct. 647, 650 n. 5, 62 L.Ed.2d 614 (1980).
Montana also recognizes the “good Samaritan” doctrine of negligence, Jeffries v. United States, 477 F.2d 52, 56 (9th Cir.1973), which imposes liability for negligent performance of an undertaking “to render services to another which [the tortfeasor] should recognize as necessary for the protection of the other’s person or things.” Restatement (Second) of Torts § 323. The Loves claim that the government breached this duty in providing loan services without due care, in failing to give the required notice. Although this claim has contractual implications, it also sounds in tort, and comes within FTCA jurisdiction.
The district court dismissed the claim on the ground that it essentially alleges denial of a public entitlement without due process, an act which has no analogue under state tort law. We disagree. As we have noted, Montana law may impose liability on lenders who foreclose or repossess property without proper notice. Nevertheless, we are not persuaded that Montana law would impose negligence liability for this type of
