This Supreme Court trivia quiz has 50 free questions with answers and covers the highest court in the land from its first session in a New York exchange building to the present nine. It takes in the landmark cases everyone half-remembers from civics class (Marbury v. Madison, Dred Scott, Plessy, Brown, Gideon, Miranda, Loving, Roe, Nixon, Bush v. Gore, Obergefell, Dobbs), the justices who shaped it (John Jay, John Marshall, Holmes, Brandeis, Warren, Thurgood Marshall, O'Connor, Scalia, Ginsburg, Sotomayor, Jackson) and the odd corners: the only justice ever impeached, the chief justice who had already been president, the halfback who made it to the bench, and the basketball court upstairs. Early questions are the ones a good citizen should get (how many justices, who confirms them). Later ones will test a law student: which act set the court at six, what the court-packing plan actually proposed, and how many petitions arrive each year. Use it for a government class, a bar-review study break or a pub quiz politics round. Every answer was checked against a documented source that appears beneath the explanation.
