Whether the Double Jeopardy Clause applies to a nonsummary criminal-contempt prosecution.
Holding
Yes. Nonsummary criminal contempt is a crime for which the Double Jeopardy Clause protects a defendant against successive prosecution and punishment.
Reasoning
The Court treated criminal contempt enforced through ordinary, nonsummary procedures as a crime "in the ordinary sense." Earlier cases had already extended to such proceedings core criminal protections, including proof beyond a reasonable doubt, counsel, notice, the privilege against self-incrimination, and a public trial. The same reasoning required application of the Double Jeopardy Clause.
The Court limited its holding to nonsummary contempt. It did not decide whether the Double Jeopardy Clause applies to summary contempt proceedings used immediately to address disruption in the courtroom.
