Donald Lewis was convicted after a jury trial of having violated 26 U.S.C. § 7203, which so far as relevant here makes it a misdemeanor for a person required to pay federal income tax to “willfully” fail to file a tax return. He appeals on two grounds: that the trial judge should have required the government to disclose the identity of the person who informed against Lewis; and that the judge’s instructions to the jury on the meaning of “willfully” were inadequate.
Lewis never finished high school (a fact germane, as we shall see, to his defense theory), yet during the period in question he was the sole proprietor of a substantial business engaged in drilling oil wells and just before that he had owned and operated a gas station. Between 1976 and 1978 he paid out more than a half million dollars in wages to the employees of his oil-well drilling business but did not pay any of the $137,000 in federal withholding taxes that were due on those wages and did not file the required withholding returns although he had them prepared. He claims that he did not file the returns because he did not have the money to pay the taxes and thought that one may not file a return without accompanying it with payment in full of any taxes due.
Prior to trial Lewis discovered that there was an informer involved in the case, and the judge held a hearing to decide whether the name of the informer should be revealed to Lewis. After hearing testimony that the informer, a “tipster,” had not provided any information included in reports prepared by Internal Revenue Service agents working on the case, nor received payment or any favorable consideration in

exchange for the tip, the judge decided not to reveal the name of the informer to Lewis. The judge’s decision was clearly right. The confidentiality of informers serves an important law-enforcement interest, especially in “victimless” crimes such as tax evasion. This interest must be balanced against the defendant’s interest in developing an effective defense. See
Roviaro v. United States,
Since the informer here was merely a tipster, we might stop with a citation to Suarez. But we need not go so far as to adopt the Fifth Circuit’s automatic rule protecting the confidentiality of tipsters’ identities in all circumstances in order to reject Lewis’s claim. The informer here, whoever he was, was not a key witness; the information that he supplied to the IRS was not even important enough to be incorporated in any of the IRS agents’ reports. The informer’s identity became particularly unimportant as the trial progressed and it became clear that the only real issue in the case was whether Lewis truly believed that he did not have to file a return unless he had the funds in hand to pay in full any taxes shown on the return to be due. There was no direct evidence on this point other than Lewis’s own testimony, which the jury had to weigh against a circumstantial background that included the fact that Lewis, despite his limited education, was an experienced businessman operating on a substantial scale. Knowing that some peripheral witness may have been an informer would not have helped Lewis to make out his defense.
We come to the major issue in the case, the adequacy of the instructions. The judge instructed the jury that “An act is done ‘willfully’ if done voluntarily and intentionally with the purpose of avoiding a known legal duty.” This instruction allowed the jury to acquit if it believed Lewis’s story that he had not known that he could, let alone that he had to, file a return even if he did not have the money to pay the taxes shown as due on it. Lewis complains however that the jury should have been instructed on this point in greater, and more homely, detail. Although we would be troubled if the only instruction given the jury on a key element of the crime charged was worded so legalistically that a lay person would have great difficulty understanding what that element was, cf.
United States v. McAnally,
Lewis’s more substantial point is that the reference to “known legal duty” was too fleeting, given that his whole defense was that he did not know he had a legal duty to file under the circumstances in which he found himself. In
Moore,
in this respect a parallel case, this court noted that the judge in his charge to the jury had repeated the definition of “willfully” several times. See
There is a deeper problem with Lewis’s objection to the instructions. The judge is obligated to instruct the jury only on a defense theory that has “some foundation in the evidence.”
Moore, supra,
If, contrary to what we have said, there was error below in failing to give a fuller instruction notwithstanding defense counsel’s failure either to tender an appropriate instruction or to lay an evidentiary foundation for the theory underlying the instructions he did tender, it was harmless error under Fed.R.Crim.P. 52(a). No rational jury would have believed Lewis’s story that he did not know that he had to file withholding tax returns. When he owned the gas station Lewis had filed such a return without accompanying payment. And as an experienced businessman he must have known that it is more, not less, important to file a return when the taxpayer is unable to pay the taxes due than when he accompanies the return with payment in full, because such filing alerts the IRS that it is not receiving taxes due it and that it had better take steps to deal with the problem. A fuller instruction would not have made Lewis’s story more plausible; it is therefore more than merely improbable, see
United States v. Valle-Valdez,
AFFIRMED.
