California
Proposition 209 (also known as the California Civil Rights Initiative or CCRI), passed by California voters in November 1996, amended the California Constitution to prohibits the state, local governments, districts, public universities, colleges, and schools, and other government instrumentalities from discriminating against or giving preferential treatment to any individual or group in public employment, public education, or public contracting on the basis of race, sex, color, ethnicity, or national origin.
Proposition 209 has been the subject of many lawsuits in state courts since its passage but has withstood legal scrutiny over the years.
