Oregon v. Kennedy, 456 U.S. 667 (1982), was a United States Supreme Court decision dealing with the appropriate test for determining whether a criminal defendant has been "goaded" by the prosecution's bad actions into motioning for a mistrial. This matters because the answer determines whether a defendant can be retried. Ordinarily, a defendant who requests a mistrial can be forced to stand trial a second time, see United States v. Dinitz. However, if the prosecution's conduct was "intended to provoke the defendant into moving for a mistrial," double jeopardy protects the defendant from retrial. The Court emphasized that only prosecutorial actions where the intent is to provoke a mistrial — and not mere "harassment" or "overreaching" — trigger the double jeopardy protection.
