The Supreme Court plays a critical role in the American political system as the highest judicial authority, interpreting the Constitution and adjudicating important legal disputes. It has the power to review laws and executive actions, ensuring they align with constitutional principles. Through landmark rulings, the Court can influence social policy, protect individual rights, and uphold legal precedents that affect society. By serving as a check on the other branches of government, the Supreme Court helps maintain the rule of law and promotes justice within the constitutional framework of the United States.
