A mistrial in a criminal prosecution may prevent retrial under the Double Jeopardy provision of the Fifth Amendment, which prohibits an individual from being tried twice for the same offense, unless required by the interests of justice and depending on which party moved for the mistrial. Typically, there is no bar to a retrial if the defendant requests or consents to a mistrial. A retrial may be barred if the court grants a mistrial without the defendant's consent, or over his objection. If the mistrial results from judicial or prosecutorial misconduct, a retrial will be barred. In United States v. Jorn, 400 U.S. 470, 91 S. Ct. 547, 27 L. Ed. 2d 543 (1971), the Supreme Court held that reprosecuting the defendant would constitute double jeopardy because the judge had abused his discretion in declaring a mistrial. On his own motion, the judge had declared a mistrial to enable government witnesses to consult with their own attorneys.
