Supreme Court of the United States The Supreme Court of the United States is the highest federal court of the United States. Established pursuant to Article Three of the United States Constitution in 1789, it has ultimate (and largely discretionary) appellate jurisdiction over all federal courts and state court cases involving issues of federal law plus original jurisdiction over a small range of cases. In the legal system of the United States, the Supreme Court is generally the final interpreter of federal law including the United States Constitution, but it may act only within the context of a case, in which it has jurisdiction. The Court does not have power to decide political questions, and its enforcement arm is in the executive rather than judicial branch of government.
United States v. Lopez United States v. Alfonso D. Lopez, Jr., 514 U.S. 549 (1995) was the second United States Supreme Court case since the New Deal to set limits to Congress' power under the Commerce Clause of the United States Constitution. The Supreme Court held that the federal Gun-Free School Zones Act of 1990, which banned possession of handguns near schools, was unconstitutional because it did not have a substantial impact on interstate commerce. After the "Lopez" decision, the act was amended to specifically only apply to guns that had been moved via interstate commerce.
