simply not so.

'The judicial power shall extend to all cases, in law and equity, arising under this Constitution,'

The Constitution does not explicitly grant the Supreme Court the power of judicial review; nevertheless, the power of this Court to overturn laws and executive actions it deems unlawful or unconstitutional is a well-established precedent. Many of the Founding Fathers accepted the notion of judicial review; in Federalist No. 78, Alexander Hamilton wrote: "A Constitution is, in fact, and must be regarded by the judges, as a fundamental law. It therefore belongs to them to ascertain its meaning, as well as the meaning of any particular act proceeding from the legislative body. If there should happen to be an irreconcilable variance between the two, that which has the superior obligation and validity ought, of course, to be preferred; or, in other words, the Constitution ought to be preferred to the statute." The Supreme Court first established its power to declare laws unconstitutional in Marbury v. Madison (1803), consummating the system of checks and balances. This power allows judges to have the last word on allocation of authority among the three branches of the federal government, which grants them the ability to set bounds to their own authority, as well as to their immunity from outside checks and balances.
