What does judicial review entail?

Judicial review is a fundamental principle in the American legal system that allows courts to evaluate the constitutionality of legislative acts, executive actions, and even state laws. When it comes to the correct answer, the power to invalidate actions of the President and Congress highlights the role of the judiciary in maintaining the balance of power among the branches of government. This process ensures that neither the legislative nor the executive branches can overstep their constitutional bounds, thereby upholding the rule of law and protecting individual rights.

Through judicial review, courts can examine laws passed by Congress and actions taken by the President to determine whether they comply with the Constitution. If a law or action is found to be unconstitutional, the court can render it invalid, thereby demonstrating the judiciary's critical function as a check on the powers of the other branches. This process reinforces the idea that the Constitution is the supreme law of the land, and all government actions must align with it to be valid.
