Defendant, Norbert Breinig, together with his former wife, Joan Moore, was charged with violating 26 U.S.C. § 7201 by wilfully attempting to evade and defeat federal income taxes for the years 1986 and 1987. The district court ordered a joint trial of the defendants. Because he anticipated that there would be antagonistic defenses, Breinig moved for severance and a separate trial under Fed.R.Crim.P. 14, which the district court denied.
Moore presented a defense of diminished capacity to negate her mens rea, which required the introduction of highly prejudicial evidence of Brеinig’s bad character; evidence that would not have been admissible against Breinig had he been tried alone. At the conclusion of a jury trial, Breinig was convicted and Moore was аcquitted.
For the reasons we explain below, we REVERSE the defendant’s conviction and sentence, and REMAND for further proceedings consistent with this opinion.
I.
On April 8, 1993, a federal grand jury indicted the defendant and his former wife, Joan Moore, on two counts of willfully attempting to evade and defeat their federal income taxes for the tax years 1986 and 1987, in violation of 26 U.S.C. § 7201. The indictment alleged that both parties wilfully un-derreported income they had earned through their family-run lawn-mowing and snowplowing business.
The district court decided to try both defendants together pursuant to Fеd.R.Crim.P. 8(b). Prior to trial, Breinig moved for severance and a separate trial under Fed. R.Crim.P. 14, a motion in which Moore joined. Breinig claimed his proposed defense would be “violently antagonistic” to that of his former wife; Moore, in turn, *852 claimed that she could not endure sitting through a joint trial with Breinig “without breaking down.” The trial court denied both motions and their joint trial proceeded as scheduled. The facts relating to the tax evasion charges are not important for purposes of this appeal. The only issue on appeal is the denial of severanсe and a separate trial for defendant Breinig.
The trial took place against a backdrop of severe antagonism between the defendants; their relationship was hоstile since before their divorce. At trial, each defendant denied responsibility for evading tax obligations and cast blame on the other. Moore claimed that she lacked the capacity to form the requisite mens rea to have evaded taxes “wil-fully” because she was dominated and controlled by Breinig, and Breinig claimed that because Moore kept all the books and an accounting firm prepared their taxes, he had no knowledge of the underreporting.
Moore’s defense of diminished capacity was based largely on the testimony of a psychiatrist and a psychologist who had treated her in 1990. Over Breinig’s objections, the expert witnesses testified to Moore’s mental instability; to her extreme insecurities; to her suicidal tendencies; to Breinig’s infidelities; and to Moore’s low self-esteem. The evidence presented to the jury showed that Breinig committed adultery during the course of his marriage to Moorе, and that he alienated the couple’s children, which caused Moore to feel abandoned by them. Additional testimony revealed that the defendant “abandoned” Moore, аnd that he “manipulated” her throughout the course of a twenty-four-year marriage resulting in Moore’s extreme dependence on Breinig. All of this evidence was admitted only in support оf Moore’s defenses, but amounted, nevertheless, to dramatic evidence of Breinig’s bad character.
After the verdict, Breinig moved for a new trial on the ground that the denial of sevеrance and separate trials denied him due process of law under the Fifth Amendment of the United States Constitution. The district court denied his motion relying on the authority of
Zafiro v. United States,
II.
This court reviews a district court’s grant or denial of a motion for new trial under an abuse of discretion standard.
United States v. Ashworth,
III.
Breinig argues that the denial of severance and sеparate trials rendered his trial unfair by denying him due process of law under the Fifth Amendment. Because of the inherently antagonistic defenses the parties presented, evidence that was admitted to support Moore’s theory of the case, and which the jury was properly permitted to consider, was at the same time highly prejudicial evidence of Breinig’s bad сharacter. This evidence would have been inadmissible against Breinig had he been tried alone.
Under Rule 8(b), defendants who are “indicted together, [ordinarily] should be tried together.”
United States v. Warner,
Notwithstanding the strong preference for joint trials, if a defendant or the government is prejudiced by joinder, Rulе 14 permits the court to grant a severance or to “provide whatever other relief justice requires.” Fed. R.Crim.P. 14. The rule leaves the determination of the risk of prejudice and aрpropriate remedy, if any, to the sound discretion of the trial judge.
Zafiro,
Breinig argues that because his defense was sharply аntagonistic to Moore’s defense he should have been granted severance. However, this is not the appropriate standard after
Zafiro.
A mutually antagonistic defense is not prejudicial
per se,
and Rule 14 does not mandate severаnce on that ground as a matter of law.

at 535-39,
Breinig’s claim of prejudice meets this standard. The unfairness in Breinig’s trial resulted not from a mutually antagonistic defense, but from evidence the jury was permitted to hear and evaluate and which was, as to Breinig, impermissible and highly inflammatory evidence of his bad character. The jury was told, by well-eredentialed experts, that Breinig was an adulterous, mentally аbusive, and manipulating spouse. Such testimony, of course, would have been inadmissible against him under any theory of the Federal Rules of Evidence on a trial for tax evasion. Becausе Breinig’s credibility was in issue, the jury’s consideration of categorically inadmissible evidence was manifestly prejudicial, and unfairly so. It provided the government with an unfair windfall that the rules of evidence and elemental notions of fairness would otherwise not allow, and that Rule 8(b) does not envision. We find, therefore, that Breinig has carried the heavy burden of showing that the prejudice he suffered was compelling and unfair.
Moore,
We note that this is an exceptional case. Indeed, its unique facts present one of those very few instances where a conviction is reversed based on a denial of severance under Rule 14. Although we find that Breinig should have been granted a separate trial, we are not critical of the district court’s pretrial decision. The district court engaged in extensive fact-finding and carefully evaluated the proposed evidence in light of the Supreme Court’s decision in
Zafiro.
On appeal, however, we have the benefit of reviewing the record and evaluating the trial after all the testimony has been presented and the jury has returned its verdict. The district court could not have foresеen much of the testimony that was ultimately introduced. We reaffirm today that the decision to deny severance rests within the sound discretion of the trial judge, which we do not second-guess.
United States v. Lasanta,
*854 IV.
Accordingly, we VACATE the conviction and sentence, and REMAND for further proceedings consistent with this opinion.
