What does California's Proposition 8 mean?

California's proposition 8 (2008) (also called the California Marriage Protection Act) was a public referendum seeking to amend the California State Constitution to eliminate the then existing right of same-sex couples to legally marry in California. California voters passed the initiative by 52% to 48% on November 5, 2008. Immediately, same-sex couples were no longer able to obtain marriage licenses in California, but same-sex marriages performed before that date were still valid.

The United States Supreme Court issued a decision on June 26, 2013, which resulted in the resumption of same-sex marriages in the state of California on June 28, 2013.
