Justice Stevens agreed that retrial was permissible on these facts, but he rejected the majority’s decision to make intent to provoke a mistrial the exclusive exception to the ordinary rule allowing retrial after a defendant requests a mistrial. In his view, the case could and should have been decided by holding that this isolated question did not amount to the overreaching or harassment recognized in prior cases.
Stevens viewed the Double Jeopardy Clause as protecting a defendant’s interest in finality and in having guilt or innocence resolved in one proceeding, while accommodating the public’s interest in a fair adjudication. When serious prosecutorial error leaves a defendant to choose between a tainted trial and a mistrial, that choice is not meaningful if the government has deliberately manipulated the trial in a way that seriously compromises the defendant’s prospects for acquittal.
The exception should therefore extend beyond a prosecutor who specifically seeks a mistrial. Deliberate misconduct intended to harass the defendant through repeated proceedings, or to inject unfair prejudice likely to secure a conviction, can equally make the defendant’s supposed choice hollow even though the prosecutor’s immediate goal is not an aborted trial.
A subjective intent-to-provoke standard would be exceptionally difficult for defendants to prove and would, in Stevens’s view, effectively eliminate a previously recognized safeguard. Courts could instead assess deliberate and egregious misconduct from objective circumstances, reserving a retrial bar for rare cases where the misconduct substantially destroys the defendant’s meaningful choice.
Nonetheless, the record did not establish such a case. The isolated question came early in the trial, the prosecutor was attempting to rehabilitate a witness after defense counsel raised the witness’s accusation against Kennedy, and the question did not create the kind of overwhelming unfair prejudice that would render Kennedy’s decision to seek a mistrial meaningless.
