The power of the courts to declare legislative enactments as unconstitutional is known as judicial review. This means that the courts have the power to review and interpret laws passed by the legislative branch of government, and if they find that such laws violate the provisions of the constitution, they can declare them null and void. Judicial review serves as a check on the power of the legislative and executive branches of government, ensuring that they do not act outside the boundaries of the constitution. It is an important feature of many democratic systems of government, and helps to ensure the protection of citizens' rights and freedoms.
