The Supreme Court plays a pivotal role in the U.S. political system by interpreting the Constitution and adjudicating legal disputes that may affect public policy. As the highest court in the land, its decisions can uphold or overturn laws, influencing a wide range of issues from civil rights to healthcare. The Court acts as a check on the executive and legislative branches, ensuring that laws align with constitutional principles. Its rulings can facilitate social change or reinforce existing norms, making it a critical arbiter in American democracy.
