What is the main function of the judicial branch of government?

The judicial branch of government primarily functions to review laws. This role is fundamental to the principle of checks and balances that underpins the U.S. government system. The judiciary interprets the Constitution and evaluates whether laws passed by the legislative branch comply with constitutional standards. This power of judicial review allows the courts to assess the legality and constitutionality of legislative and executive actions.

Through this function, the judicial branch ensures that laws adhere to the Constitution, protecting individual rights and maintaining the rule of law. For instance, if a law is challenged and deemed unconstitutional, the judiciary has the authority to strike it down, thereby upholding the principles of justice and fairness within the legal system. This process is crucial in safeguarding democracy and ensuring accountability among the branches of government.
