Gratz v. Bollinger, 539 U.S. 244 (2003), was a United States Supreme Court case regarding the University of Michigan undergraduate affirmative action admissions policy. In a 6–3 decision announced on June 23, 2003, Chief Justice Rehnquist, writing for the Court, ruled the University's point system's "predetermined point allocations" that awarded 20 points to underrepresented minorities "ensures that the diversity contributions of applicants cannot be individually assessed" and was therefore unconstitutional.
