The Michigan Civil Rights Initiative (MCRI), or Proposal 2, was a ballot initiative in the U.S. state of Michigan that passed into Michigan Constitutional law by a 58% to 42% margin on November 7, 2006, according to results officially certified by the Michigan Secretary of State. By Michigan law, the Proposal became law on December 22, 2006. MCRI was a citizen initiative aimed at banning consideration of race, color, sex, or religion in admission to colleges, jobs, and other publicly funded institutions – effectively prohibiting some affirmative action by public institutions based on those factors. The Proposal's constitutionality was challenged in federal court, but its constitutionality was ultimately upheld by the Supreme Court of the United States.

Proposition 209 is a California ballot proposition which, upon approval in November 1996, amended the state constitution to prohibit state governmental institutions from considering race, sex, or ethnicity, specifically in the areas of public employment, public contracting, and public education. Modeled on the Civil Rights Act of 1964, the California Civil Rights Initiative was authored by two California academics, Glynn Custred and Tom Wood. It was the first electoral test of affirmative action policies in North America. It passed with 55% in favor to 45% opposed, thereby banning affirmative action in the state's public sector.
