Cornell law professor Michael C. Dorf discusses the double jeopardy question raised in Gamble v. United States, in which the US Supreme Court heard oral arguments last week, and explains how the extraordinary nature of the Trump presidency should inform judicial decision making. Building upon a point made in a 1985 Columbia Law Review article by Professor Vincent Blasi, Dorf argues that judges construing the Constitution and other legal texts in perilous times such as these should keep in mind that the rules they adopt will also operate in normal times.
