What is the theory of independent of the judiciary

Independence means literally to be free. The Judiciary is a branch of the United States government made up of the Courts of Law. The Judiciary is responsible for interpreting the Laws made by the Legislative branch.

The Independence of the Judiciary has to do with the Judiciary's freedom to carry out their duties without any external interference from the other branches of government. Judges should act in good faith concerning any matter brought before it. They are to ensure justice is done in all cases with the application of relevant laws without being compelled by another.
