Text: In 1803, the Supreme Court established judicial review of federal legislation in Marbury v. Madison, holding, however, that Congress could not grant unconstitutional power to the Court itself. The Constitution does not explicitly state that the courts may exercise judicial review; however, the notion that courts could declare laws unconstitutional was envisioned by the founding fathers. Alexander Hamilton, for example, mentioned and expounded upon the doctrine in Federalist No. 78. Originalists on the Supreme Court have argued that if the constitution doesn't say something explicitly it is unconstitutional to infer what it should, might or could have said. What this means is that the Supreme Court can nullify a congressional law. It is a huge check by the courts on the legislative authority and limits congressional power. In 1851, for example, the Supreme Court struck down provisions of a congressional act of 1820 in the Dred Scott decision. However, the Supreme Court can also extend congressional power through its constitutional interpretations.
