Civil rights groups will hold a news conference at San Francisco City Hall today following the California Supreme Court's ruling on the legal challenge to Proposition 8, the state's voter-approved ban on same-sex marriage.
The decision is expected to be issued at 10 a.m. at the court's headquarters at the State Building in San Francisco.
It will also be available online at the Supreme Court Decision site.
Prior to the news conference, the group will gather on the steps of the State Building to hear the court's ruling.
The court is expected to issue its decision on three lawsuits that claim the measure is unconstitutional.
Proposition 8, by amending the constitution, overturned a state high court ruling from a year ago that said gay and lesbian couples have a constitutional right to marry.
