how is the supreme court able to check the other branches using Judicial review?

The Supreme Court is able to check the other branches of government, including the legislative and executive branches, through the power of judicial review.

Judicial review is the process by which the Supreme Court can review the actions and decisions of the other branches of government to determine whether they are constitutional. If the Court finds that a law or action is unconstitutional, it can strike it down and prevent it from being enforced. This power allows the Supreme Court to keep the other branches of government in check and ensure that they are acting within the bounds of the Constitution.

By exercising judicial review, the Supreme Court acts as a check on the power of the other branches of government and helps to uphold the principles of separation of powers and checks and balances in the United States government.
