Step-by-step explanation:
In the United States, the final word in settling significant issues that challenge the government rests with the judicial branch of government, specifically the Supreme Court. The Supreme Court is the highest court in the land and has the power of judicial review, which means it can interpret and apply the Constitution to determine the constitutionality of laws and actions taken by the government.
For example, if a law is passed that some people believe violates the Constitution, it can be challenged in court. The Supreme Court ultimately has the authority to declare the law unconstitutional and therefore invalid.
This system of checks and balances ensures that no one branch of government has too much power and that the Constitution is upheld as the supreme law of the land.
