In the March 7, 2000 primary election, Proposition 22 was adopted by a vote of 61.4% to 38%, thus adding § 308.5 to the Family Code, largely replicating the 1977 enactment. The one-sentence code section explicitly defined the union of a man and a woman as the only valid or recognizable form of marriage in the State of California. Proposition 22 was authored by State Senator William J. Knight, and the measure was dubbed the "Knight initiative" in an attempt to link it to the failed "Briggs Initiative" (Proposition 6 of 1978) that would have banned gays and lesbians from working as teachers in California's public schools. The California Supreme Court invalidated the results of Proposition 22 in 2008.
