Croson Co., 488 U.S. 469 (1989), was a case in which the United States Supreme Court held that the minority set-aside program of Richmond, Virginia, which gave preference to minority business enterprises (MBE) in the awarding of municipal contracts, was unconstitutional under the Equal Protection Clause.

The evidence that was introduced included: a statistical study indicating that, although the city's population was 50% black, only 0.67% of its prime construction contracts had been awarded to minority businesses in recent years; figures establishing that a variety of local contractors' associations had virtually no MBE members; the city's counsel's conclusion that the Plan was constitutional under Fullilove v. Klutznick, 448 U.S. 448; and the statements of Plan proponents indicating that there had been widespread racial discrimination in the local, state, and national construction industries.

Pursuant to the Plan, the city adopted rules requiring individualized consideration of each bid or request for a waiver of the 30% set-aside, and providing that a waiver could be granted only upon proof that sufficient qualified MBE's were unavailable or unwilling to participate The Supreme Court stated: We, therefore, hold that the city has failed to demonstrate a compelling interest in apportioning public contracting opportunities on the basis of race.

The dream of a Nation of equal citizens in a society where race is irrelevant to personal opportunity and achievement would be lost in a mosaic of shifting preferences based on inherently unmeasurable claims of past wrongs.

Courts would be asked to evaluate the extent of the prejudice and consequent harm suffered by various minority groups.
