This document provides an overview of the basic principles of establishing liability under 42 U.S.C. § 1983. It notes that to establish a § 1983 claim, a plaintiff must assert the deprivation of a federal right. A violation of state law alone is not sufficient. It also discusses that § 1983 does not provide a basis for redressing violations of state law, but rather violations of federal law committed under color of state law. The document provides preliminary background on key § 1983 concepts such as the requirement that the deprivation be under color of state law, statute of limitations issues, the distinction between individual and official capacity suits, and limitations on various types of liability.
