What is the role of the Supreme Court in the judicial branch?

The Supreme Court plays a crucial role in the judicial branch primarily through its responsibility to interpret the Constitution. This function allows the Court to ensure that laws and policies enacted by the legislative and executive branches align with constitutional principles. By interpreting the Constitution, the Supreme Court can evaluate the legality of government actions, make decisions in landmark cases that can set important precedents, and protect individual rights against potential government overreach. This interpretative authority serves as a fundamental check on the powers of the other branches of government, maintaining the balance of power essential to the function of democracy.
