Village of Arlington Heights v. Metropolitan Housing Development Corp, 429 U.S. 252 (1977), was a case heard by the Supreme Court of the United States dealing with a zoning ordinance that in a practical way barred families of various socio-economic, and ethno-racial backgrounds from residing in a neighborhood. The Court held that the ordinance was constitutional because there was no proof that "discriminatory purpose was a motivating factor in the Village's decision."
