A jury сonvicted Edward J. Krenzelok and John Law Freeman (the
nom de guerre
of Alton R. Moss) of federal mail fraud. The judge sentenced Krenzelok to nine months in prison (plus $3,000 in fines) and Freeman to four years. Freeman, the mastermind of the scheme, is a leader of the tax protester movement. See
United States v. Moss,
At trial the government presented much evidence that the leases were phony and that Krenzelok had never made any payments to the trust. Krenzelok’s principal defense was that he had relied on Freeman’s assurances thаt the trust and the leases were valid and proper. Freeman, who represented himself at trial, had essentially no defense, beyоnd his argument that the case should be governed by the princi- *482 pies of the law of nature rather than the law of the United States becаuse of the government’s mendacious concealment of things ominous and astonishing such as that General MacArthur’s superior in Koreа was a Russian general and John Wilkes Booth’s real name was Rothschild.
The only question that merits discussion is the admissibility of a statement that United States District Judge Robert Warren, who did not preside at the trial of Krenzelok and Freeman, had made to Krenzelok back in February 1986, sevеral months before the mailings for which Freeman and Krenzelock were indicted. The occasion was a proceeding befоre Judge Warren by the Internal Revenue Service to collect unpaid taxes from Krenzelok. Krenzelok testified regarding the operations of the trust and at the end of the hearing Judge Warren told him, “I think it’s self-evidence [sic ] that the trust indentures in this instance, alleging the creаtion of the trusts in the hands of the Premm Company and the Kremp Company [names under which Krenzelok conducted his septic-tank-cleаning business] are fallacious as a matter of law, and are incompetent to create genuine trusts.” This statement was admitted into evidence at the trial of Krenzelok and Freeman together with an instruction telling the jury that it was being admitted “for the sole limited purpose of showing what was said to Mr. Krenze-lok, and that he heard those statements on February 7, 1986, ... so that the jury may consider what influence, if any, that mаy have, or what effect, if any, that may have on subsequent actions that Mr. Krenzelok took in this case.” This was a convoluted way of tеlling the jury they could consider Judge Warren’s statement only for its bearing on Krenzelok’s defense that he had acted in good faith in mailing the bаckdated leases. Krenzelok and Freeman argue that the prejudicial effect of a federal judge’s statement that the trust was invalid substantially outweighed its probative value, rendering it inadmissible under Rule 403 of the Federal Rules of Evidence.
The balancing of probative value and prejudicial effect, like other comparisons of intangibles, requires an exercise of judgment rather than a computation. Only in an extreme case are appellate judges competent to secondguess the judgment of the pеrson on the spot, the trial judge. The present case is unusual but not extreme. It is unusual for a federal judge to appear, directly оr indirectly, as a witness. There are exceptions: a case of criminal contempt for example, or a case in whiсh a judge is called as a character witness for the defendant. It would be particularly unusual, and usually improper, for the judge in a criminal case to admit the testimony or other statement of another judge regarding a question of law. For with the diminishing exception of questions of foreign law, see Fed.R.Civ.P. 44.1 (adopted in 1966); Miller, Federal Rule 44.1 and the “Fact” Approach to Determining Foreign Law: Death Knell for a Die-Hard Doctrine, 65 Mich.L.Rev. 613 (1967), questions of law are not matters for proof at all; they are matters on which the presiding judge instructs the jury. If Judge Evans had admitted Judge Warren’s statement for the purpose of proving that Krenzelok’s trust was invalid, this would have been gratuitous; Judge Evans shоuld simply have instructed the jury that the trust was invalid. But it would have been an error in Krenzelok’s favor.
The statement, however, was not admitted to establish the invalidity of the trust, but to controvert Krenzelok's defense that he believed the trust to be valid. The significance of Judge Warren’s testimоny was that only a few months before attempting to enforce the trust through backdated leases, Krenzelok had been told unequivocally by a federal judge whose ruling he did not attempt to appeal that the trust was invalid. The fact that he had been told this was not only rеlevant to the government’s effort to rebut Krenzelok’s defense of good faith; it was — as Krenzelok’s counsel acknowledged at oral argument — “indispensable.” Its probative value was therefore great. Its prejudicial effect may well have been great too. But when the trial judge is in doubt, Rule 403 requires admission (this is the force of
“substantially
outweighed”); and when
*483
the appellate judges are in doubt, a proper regard for thе comparative advantages of trial and appellate judges counsels us to uphold the trial judge’s application оf the rule. It is unnecessary to add that any error in the admission of Judge Warren’s statement was harmless. A rational jury could not have acquittеd Krenzelok, who, even if he believed the trust valid, could not have believed that backdated leases, and false representations that he had made payments on them, were the proper means of enforcing the trust. To commit fraud in pursuit of a lawful end is nevertheless to commit fraud. Cf.
