In the early 1940s, black actors and businessmen had begun to move into Beverly Hills, despite the covenants allowing only whites to live in the city. A neighborhood improvement association attempted to enforce the covenant in court. The defendants included such luminaries as Hattie McDaniel, Louise Beavers, and Ethel Waters. Among the white residents supporting the lawsuit against blacks was silent film star Harold Lloyd. The NAACP participated in the defense, which was successful. In his decision, federal judge Thurmond Clarke said that it was time that "members of the Negro race are accorded, without reservations or evasions, the full rights guaranteed to them under the 14th amendment. " The United States Supreme Court declared restrictive covenants unenforceable in 1948 in Shelley v. Kraemer. A group of Jewish residents of Beverly Hills filed an amicus brief in this case.
