What does judicial review allow the courts to do?

Judicial review is a principle that enables courts to evaluate and determine the constitutionality of legislative acts and executive actions. This function is crucial in maintaining the balance of power among the branches of government by allowing the judiciary to interpret the law and ensure that laws or actions do not violate the Constitution. When a law is challenged, the court assesses whether it aligns with constitutional provisions, thus safeguarding individual rights and upholding the rule of law. This process establishes the judiciary not only as a body that interprets laws but also as one that serves as a check on the legislative and executive branches, reinforcing the importance of judicial oversight in a democratic system.
