What is the test for a jury to acquit a defendant in a fraud case?

The district court instructed the jury that the government had to prove that defendant acted with specific intent to defraud. It further explained that to act with specific intent to defraud a person must act willfully and with the intent to deceive or cheat. We are confident that if the jury found that Pratt honestly believed he had permission to endorse the check, then under the instructions it was given, it would have been required to return an acquittal. Pratt was not entitled to a separate good faith instruction. See United States v. Bonanno, 852 F.2d 434, 440 (9th Cir.1988), cert. denied, 488 U.S. 1016 (1989); United States v. Solomon, 825 F.2d 1292, 1295 (9th Cir.1987), cert. denied, 484 U.S. 1046 (1988).
