Judicial Review: The Supreme Court's ability to review the constitutionality of legislative and executive acts.
The Supreme Court declared that the Constitution was “superior, paramount law”. The Supreme Court decided that if ordinary laws cause conflict with the Constitution, they shall be deemed unconstitutional. It is the job of the Supreme Court, through judicial review, to interpret the Constitution and review a law's constitutionality. Judicial heavily expanded the power power of the federal government, more specifically the Supreme Court, as they could also question the constitutionality of state's laws as well. For instance, if a law violates a person's civil liberties that are listed in the Constitution, the Supreme Court can strike it down.
