Shelley v. Kraemer is a landmark 1948 Supreme Court case that addressed the issue of racially restrictive covenants in housing. The Court ruled that while private parties may create such agreements to prevent people of certain races from buying property, the enforcement of these covenants by state courts constitutes state action and is thus prohibited under the Equal Protection Clause of the 14th Amendment. This case marked a significant step in the fight against housing discrimination, as it established that judicial enforcement of racially discriminatory practices was unconstitutional.
