Section 25 of the Judiciary Act of 1789 provides that the U.S. Supreme Court can review state laws to determine whether they comport with the Constitution. The section reads that where “the validity” of a state law is questioned “on the ground of being repugnant to the constitution, treaties or laws of the United States,” the U.S. Supreme Court has jurisdiction. This section originally caused great controversy, as many believed that the rights of the states were being invaded by the federal government and its courts.
