Final answer:
The Supreme Court has the power of judicial review to declare laws unconstitutional, impacting laws passed by Congress through validation. This process upholds the system of checks and balances in the government.
Explanation:
The main power of the Supreme Court is its authority to declare laws and actions by the executive branch unconstitutional. This power is known as judicial review, which was established in the case of Marbury v. Madison in 1803.
When the Supreme Court rules a law unconstitutional, it can affect laws Congress passes by invalidating them. Congress may then need to rewrite the law or start the process of a constitutional amendment to address the Court's decision.
Additionally, the Supreme Court helps maintain a system of checks and balances within the government, ensuring that no single branch has too much power.
