Heading: Federal Preemption: General Background

Text: Federal preemption arises from the Supremacy Clause of the U.S. Constitution and is the concept that state laws that conflict with federal law are invalid. U.S. Const. art. VI, cl. 2. See Scott A. Smith and Duana Grage, Federal Preemption of State Products Liability Actions, 27 Wm. Mitchell L.Rev. 391 (2000) (citing sources). There are three varieties of preemption: express, implied, and conflict preemption. See id. Express preemption arises when Congress has explicitly declared federal legislation to have a preemptive effect. It can also arise when a federal agency, acting within the scope of authority conferred upon it by Congress, has expressly declared an intent to preempt state law. Id. This case involves issues of express preemption.
