A) West Virginia State Board of Education v. Barnette (1943) CORRECT This Supreme Court decision is a landmark case involving the Free Exercise Clause. The Court ruled that compelling students to salute the flag and recite the Pledge of Allegiance violated their religious freedom, specifically for Jehovah's Witnesses. The decision emphasized that the government cannot force individuals to express beliefs contrary to their religious convictions, even in the interest of national unity. This case remains a cornerstone of First Amendment jurisprudence, protecting individual conscience against state coercion.
B) McCulloch v. Maryland (1819) INCORRECT This case dealt with the scope of federal power and the Necessary and Proper Clause, not religious freedom. The Supreme Court, led by Chief Justice John Marshall, held that Congress had implied powers to create a national bank and that states could not tax federal institutions. The decision established the principle of federal supremacy and the doctrine of implied powers, which are fundamental to constitutional law but unrelated to the Free Exercise Clause.
C) Marbury v. Madison (1803) INCORRECT This case is famous for establishing the principle of judicial review, which allows the Supreme Court to declare laws unconstitutional. It arose from a political dispute over a judicial appointment and did not involve religious issues. The decision, written by Chief Justice John Marshall, affirmed the Court's authority to interpret the Constitution, but it has no connection to the Free Exercise Clause.
D) Plessy v. Ferguson (1896) INCORRECT This case upheld racial segregation under the 'separate but equal' doctrine, which was later overturned by Brown v. Board of Education. It dealt with the Equal Protection Clause of the Fourteenth Amendment, not religious freedom. The decision allowed states to require racial segregation in public facilities, but it has no bearing on the Free Exercise Clause.
