The Supreme Court serves a critical role in American politics as the apex judicial authority. It interprets the Constitution, reviews legislation, and resolves disputes that affect the nation. Its rulings can shape public policy and address fundamental rights, as seen in landmark cases regarding abortion, free speech, and same-sex marriage. By exercising judicial review, the Court checks legislative and executive powers, ensuring the balance of power in a democratic system. Its decisions influence partisan debates and can catalyze significant shifts in public opinion.
