What does the principle of judicial review enable the judiciary to do?

The principle of judicial review empowers the judiciary to examine the actions of the legislative and executive branches to determine their constitutionality. This means that if a law or executive action is found to violate the Constitution, the courts have the authority to declare it unconstitutional and, therefore, null and void. This function serves as a check on the powers of the other branches of government, ensuring that they do not exceed their constitutional authority. The significance of judicial review lies in its role in upholding the rule of law and protecting individual rights against potential governmental overreach. This mechanism is vital in maintaining the balance of power within the government framework established by the Constitution.
