1996 California Proposition 209
Proposition 209 (also known as the California Civil Rights Initiative or CCRI) 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.
