The Supreme Court is able to check the other branches, specifically the executive and legislative branches, using judicial review. Judicial review is the power of the court to determine the constitutionality of laws and actions taken by the other branches. When a case is brought before the Supreme Court, it has the authority to review the laws or actions in question and decide whether they are in accordance with the Constitution. If the court finds that a law or action is in violation of the Constitution, it can declare it unconstitutional, effectively nullifying it. This allows the court to act as a check on the other branches, ensuring that their actions are in line with the principles and limitations set forth by the Constitution.
