Egelhoff v. Egelhoff, 532 U.S. 141 (2001), is a major decision of the Supreme Court of the United States on federalism, specifically with regards to the preemption powers of federal law over state laws. It sets the precedent that any state statutes having a "connection with" ERISA plans are superseded by ERISA, or any future substantially similar law that takes its place. In essence, this decision is a reaffirmation of the right and ability of the federal government to, at least in some instances, pre-empt state laws.
