The State Supreme Court is hearing a challenge to the state law that defined marriage as being between a man and a woman. The lower courts have been split, with the lowest court finding the law unconstitutional, while the court of appeals upheld the law.
The Supreme Court will now weigh in to see whether it believes California's law is constitutional.
"The case combines four lawsuits - three by nearly two dozen couples who want to marry and the fourth by the city of San Francisco, which entered the dispute after the court overturned Mayor Gavin Newsom's order that cleared the way for nearly 4,000 same-sex weddings in February and March 2004.
The suits rely on the California Constitution, which state courts have long interpreted as more protective of individual rights than the U.S. Constitution. The plaintiffs invoke a passage in the 1948 ruling on interracial marriage - the first of its kind by any state's high court - in which the justices recognized a "right to join in marriage with the person of one's choice."
Judge Richard Kramer of San Francisco Superior Court echoed that language in March 2005, when he ruled that the state's ban on same-sex marriage violated "the basic human right to marry a person of one's choice." He also said the marriage law constitutes sex discrimination - prohibited by another groundbreaking California Supreme Court ruling in 1971 - because it is based on the gender of one's partner.
But a state appeals court upheld the law in October 2006. In a 2-1 decision, the court rejected Kramer's findings of discrimination and said California was entitled to preserve the historic definition of marriage while taking steps to protect the rights of same-sex couples who register as domestic partners."
