The most relevant fact to the Supreme Court's influence on America is that it is the highest court in the United States and has the power of judicial review. This means that the Supreme Court has the authority to interpret the Constitution and determine the constitutionality of laws and government actions. As such, the Court's decisions can have far-reaching consequences on American society, politics, and law, and can shape the interpretation and application of the Constitution for generations to come. The Court's decisions can also impact individual rights, civil liberties, and social and economic issues.
