Held. Yes. Conviction affirmed.
Willfulness requires the government to prove that the law imposed a duty, that the defendant knew of the duty, and that he voluntarily and intentionally violated the duty.
Under this definition of willfulness, it is clear that the Defendant cannot be convicted of willfully violating the law if he was not aware of the law.
