AP U.S. Government & Politics Required Supreme Court Cases 2026/2027 | 18 Questions & Answers | Judicial Review, Federalism, Civil Liberties, Civil Rights & First Amendment |

This AP U.S. Government and Politics (AP Gov) Required Court Cases 2026/2027 study guide contains 18 Supreme Court case questions and answers across 4 pages. It provides a focused review of landmark cases involving judicial review, federalism, separation of powers, civil liberties, civil rights, the First and Second Amendments, equal protection, due process, voting and redistricting, campaign finance, and the Commerce Clause. The concise case-and-ruling format makes the document suitable for memorizing the constitutional principles and holdings associated with major AP Government Supreme Court cases. The guide begins with foundational cases defining the relationship between the federal government, states, and the judiciary. McCulloch v. Maryland (1819) addresses federal supremacy, while Marbury v. Madison (1803) establishes judicial review. United States v. Lopez (1995) examines limits on congressional power under the Commerce Clause. Together, these cases support review of core AP Government concepts involving federalism, constitutional authority, and judicial power. A major section covers First Amendment freedoms of speech, religion and the press. Schenck v. United States (1919) addresses limits on speech involving a “clear and present danger”; Engel v. Vitale (1962) examines school-sponsored religious activity under the Establishment Clause; and Wisconsin v. Yoder (1972) concerns religious liberty under the Free Exercise Clause. Tinker v. Des Moines (1969) reviews student expression in public schools, while New York Times Co. v. United States (1971) addresses freedom of the press and the heavy presumption against prior restraint. The document also reviews landmark civil rights, equal protection and criminal-procedure cases. Brown v. Board of Education (1954) addresses racial segregation and the Equal Protection Clause; Baker v. Carr (1962) concerns judicial review of redistricting disputes and the development of the “one person, one vote” principle; and Shaw v. Reno (1993) focuses on race and legislative redistricting. Criminal justice cases include Mapp v. Ohio (1961) on the exclusionary rule, Gideon v. Wainwright (1963) on the right to counsel, and Miranda v. Arizona (1966) on protections afforded to suspects in custody. Additional high-value cases include McDonald v. Chicago (2010) concerning application of the Second Amendment right to the states and Citizens United v. Federal Election Commission (2010) concerning political spending and First Amendment protection. The guide also includes Buckley v. Valeo (1976) on campaign-finance restrictions and Roe v. Wade (1973) as a historical case concerning privacy and abortion. For students preparing for AP Government assessments, these cases connect Supreme Court decisions to broader concepts such as constitutional interpretation, incorporation, federal versus state authority, individual rights, equal protection, political participation, elections, judicial power and checks and balances. The question-and-answer structure is especially useful for rapid recall before unit tests, cumulative reviews, mock examinations, and the AP U.S. Government and Politics exam.
