Article 3, Section 2, Clause 1
James Madison, Observations on Jefferson's Draft of a Constitution for Virginia15 Oct. 1788Papers 11:293
In the State Constitutions & indeed in the Fedl. one also, no provision is made for the case of a disagreement in expounding them; and as the Courts are generally the last in making their decision, its results to them, by refusing or not refusing to execute a law, to stamp it with its final character. This makes the Judiciary Dept paramount in fact to the Legislature, which was never intended, and can never be proper.
