California is seen as one of the most liberal states in the U. in regard to lesbian, gay, bisexual, transgender (LGBT) rights, which have received nationwide recognition since the 1960s.

Same-sex sexual activity has been legal in the state since 1976.

Mental health providers are prohibited from participating in reparative therapy for LGBT minors. Same-sex marriage was legalized in 2008 for five months until voters approved a ban in November of the same year.

After the Supreme Court refused to recognize the legal standing of same-sex marriage opponents on June 26, 2013, the ban was no longer enforceable, allowing same-sex marriages to recommence starting on June 28.

This initiative was struck down by the California Supreme Court in In re Marriage Cases, but a few months later, Proposition 8 reinstated California's ban on marriages for same-sex couples. Court of Appeals for the Ninth Circuit upheld the district court's holding in Perry v.

During the time between the California Supreme Court decision and passage of Proposition 8, the state allowed for tens of thousands of marriage licenses to be issued to same-sex couples. Horton affirmed that those marriages were still valid after passage of Proposition 8. Schwarzenegger determined that Proposition 8 was unconstitutional due to violations of the Due Process and Equal Protection clauses of the Fourteenth Amendment to the United States Constitution, but the United States Court of Appeals for the Ninth Circuit ordered a stay of the judgement pending appeal. Schwarzenegger that Proposition 8 was unconstitutional, although on narrower grounds.

It was signed on August 17, 1977 by Governor Edmund Brown (who also signed its repeal via SB 1306).

On October 12, 2009, following the passage of Proposition 8, Governor Arnold Schwarzenegger signed into law The Marriage Recognition and Family Protection Act (SB 54), legislation proposed by State Senator Mark Leno.

After the California Supreme Court challenge following the passage of Proposition 8, the California Supreme Court Justices affirmed that all same-sex marriages performed in California before the passage of Proposition 8 continued to be valid and recognized as "marriage".

Most support for LGBT rights can be seen in the largest cities, such as Los Angeles, San Diego, and San Francisco, as well as many cities on the Pacific coast.
