California is bracing for a major court decision.
The state's supreme court is scheduled to rule Tuesday, on whether a voter-approved ban on same-sex marriage is legal.
It's the same court that legalized same-sex marriages in California last year, by a four-to-three vote.
In November, California voters passed Proposition Eight, a constitutional amendment that overturned the ruling.
Gay rights advocates say the results of that vote should be thrown out on procedural grounds. They say "Prop 8" needed legislative approval before it went to voters.
