the reworked P/N 117971 bearings bears a rubber stamp facsimile of his signature. That is the sum total of the direct evidence linking Tonks to the sale of the mislabeled bearings. At trial he testified that he had no knowledge of the origin or subsequent use of the bearings until the government began its investigation.
The government argues that the requisite guilty knowledge on the part of Tonks can be inferred from the facts that he was in close contact with defendant Crawford and that the purchase order for the P/N 117971 bearings was signed less than three weeks before execution of the Navy contract.
We think these inferences are too weak to take the place of missing facts. The government did not prove a case against Tonks, and the district court’s finding to the effect that he knowingly caused the presentation of a false claim was clearly erroneous.
II. Failure to Inspect
The government admits that the Navy did not perform the “100% final inspection” called for by the contract. Defendants proved at trial that a simple and inexpensive non-destructive test, the Rockwell Hardness Test, would have shown that the bearings did not meet contract specifications.
The inspection clause in the contract does not, however, insulate appellants from liability for fraud. First, a reading of the clause shows that it is for the government’s benefit and imposes no duty on the government in favor of the appellants. Second, Article 5, the inspection article, provides that inspection is not conclusive “as regards latent defects, fraud, or such gross mistakes as to amount to fraud.” This provision embodies the established rule that, even where final inspection is the obligation of the government, such obligation does not absolve a contractor on liability for fraud. See United States v. American Packing Corp., 125 F.Supp. 788 (D.N.J. 1954); United States v. United States Cartridge Co., 95 F.Supp. 384 (E.D.Mo. 1950), aff’d, 198 F.2d 456 (8th Cir. 1952), cert. denied, 345 U.S. 910, 73 S. Ct. 645, 97 L.Ed. 1345 (1953); United States v. Collyer Insulated Wire Co., 94 F.Supp. 493 (D.R.I.1950).
To the extent that the wording of the clause itself does not militate in defendants’ favor, they rely on the so-called “Christian doctrine” as a second line of defense based on the failure to inspect.
Briefly put, Aerodex argues that, regardless of the wording of the contract, if the government had performed the tests required by specific Armed Services regulations, it would have discovered irregularities long before any of the bearings were installed in aircraft engines, and most of the consequential damages flowing from the “retrofit” program would have been eliminated. Aerodex contends that these regulations are a part of the contract as a matter-of law.
G. L. Christian & Associates v. United States, 312 F.2d 418, 160 Ct.Cl. 1, cert. denied, 375 U.S. 954, 84 S.Ct. 444, 11 L.Ed.2d 314 (1963), was a suit for lost profits by contractors whose housing project had been cancelled by the government when the Army decided to deactivate Fort Polk, Louisiana. The court held that anticipated profits were not allowable because, even though the contract did not contain any express provision allowing the government to terminate the contract for its convenience, the government was entitled to the benefit of the Armed Services Procurement Regulations which required that such a clause be inserted in all construction contracts. The court held that the standard termination article required by the Regulations was incorporated in the contract by operation of law, even though it was not contained therein expressly.
Subsequently, the Court of Claims held that this Christian doctrine could be applied for the benefit of a claimant, as well as the United States. Moran Bros., Inc. v. United States, 346 F.2d
