Los Angeles County, California v. Craig Arthur Humphries

Summary

The Court held that the policy or custom requirement from Monell v. New York City Dept. of Social Servs. applies to claims for prospective relief under 42 U.S.C. § 1983 just as it applies to claims for monetary damages. Consequently, a municipal entity is liable only if its own policy or custom caused the alleged deprivation, regardless of the form of relief sought.
