The role of the Supreme Court in the United States political system is to interpret the Constitution and evaluate the legality of laws and actions by the government. As the highest court in the land, it ensures that justice is served and constitutional rights are upheld. The Supreme Court also has the authority to strike down laws and executive actions that violate constitutional principles through judicial review. Decisions made by the Supreme Court can have far-reaching impacts on various aspects of American life, from civil rights to economic policy.
