From 1938 until 1995, the U.S. Supreme Court did not invalidate any federal statute as exceeding Congress' power under the Commerce Clause. Most actions by the federal government can find some legal support among the express powers, such as the Commerce Clause, whose applicability has been narrowed by the Supreme Court in recent years. In 1995 the Supreme Court rejected the Gun-Free School Zones Act in the Lopez decision, and also rejected the civil remedy portion of the Violence Against Women Act of 1994 in the United States v. Morrison decision. Recently, the Commerce Clause was interpreted to include marijuana laws in the Gonzales v. Raich decision.
