The Supreme Court plays a crucial role in a democratic society by interpreting the law and ensuring justice. As the highest court in the United States, it serves as the final arbiter of legal disputes and has the authority to rule on the constitutionality of federal and state laws. Through its decisions, the Supreme Court protects civil liberties and rights, shaping important legal precedents that can influence societal norms. Additionally, its power of judicial review allows it to invalidate laws that conflict with the Constitution, making the court vital for maintaining the rule of law and safeguarding democratic principles.
