How can supreme court exert control over the legislature of the US?

Answer 1

The US Supreme Court's power of judicial review, the ability to analyze laws to determine whether they're constitutional as written and as-applied, serves as a check on the Legislative Branch (Congress) because the Supreme Court has the ability to nullify (overturn and render unenforceable) unconstitutional laws.

It is important to note that the Supreme Court can't rule on every piece of legislation passed; it can only evaluate laws relevant to cases or controversies before the Court. It cannot investigate and nullify a law on its own initiative.

US District Courts, the US Court of International Trade, and US Court of Appeals Circuit Courts also have the power of judicial review, but their decisions may be appealed, whereas US Supreme Court decisions may not.

Answer 2

The Supreme Court, through the power of judicial review, can exert control over the legislature of the US by reviewing the constitutionality of laws passed by Congress. If the Court finds a law to be unconstitutional, it can strike it down, effectively negating the legislative action. This power allows the Court to act as a check on the legislature, ensuring that laws adhere to the principles and limitations outlined in the Constitution.
