• The Supreme Court could issue a historic, sweeping ruling striking down Proposition 8, finding any such state ban unconstitutional. This would end the legal debate nationwide, and it could be just a matter of weeks before same-sex marriages could occur in California.
  • The court could uphold a 2012 federal appeals court ruling that, on narrow grounds, found Proposition 8 unconstitutional. Or the justices could decide they never should have taken up the case, leaving the appeals court decision intact. Either action would clear the path for same-sex marriages in California only.
  • The court can uphold Proposition 8, ruling that it is a state's right to define its marriage laws. This would surely thrust the issue back into the political arena, where gay marriage supporters would ask the state's voters to overturn the ban.
  • Finally, the court could muddle the immediate future of gay marriage in California by deciding that Proposition 8 backers never had a legal right, or "standing," to defend the law in lieu of the governor and attorney general, who consider it unconstitutional. This outcome, in short, would send the case back to a federal judge's 2010 ruling finding Proposition 8 unconstitutional.
    The latter outcome, which has been considered a strong possibility since the Supreme Court heard arguments in March, has generated the most debate.
    The crux of that debate is whether former Chief U.S. District Judge Vaughn Walker's original ruling invalidating Proposition 8 would have statewide effect, or whether it would be confined to the two couples who sued to block the law and their two counties, Alameda and Los Angeles.
    Because Walker's injunction covered state officials, Gov. Jerry Brown and Attorney General Kamala Harris are widely expected to argue that clerks across the state can no longer enforce Proposition 8. But Proposition 8 backers, and some legal scholars, say there are serious questions about that interpretation, saying a single federal judge may not have such broad authority.
    Andrew Pugno, counsel for ProtectMarriage.com, Proposition 8's sponsors, says there will be further fights, some in the state courts, over the issue if the Supreme Court decides the case on standing grounds.
    "There will be a dogfight over what we have to do with Judge Walker's decision," promised John Eastman, a Chapman University law professor who earlier in the case unsuccessfully tried to contest Walker's ruling on behalf of Imperial County.
    Lawyers for the couples say Walker's ruling clearly blocks the state from denying marriage licenses to same-sex couples. And many legal scholars agree.
    "The ... injunction keeps the governor, the AG (attorney general), the registrar of records, from enforcing Proposition 8," said Erwin Chemerinsky, dean of UC Irvine's law school. "They cannot disobey this injunction, and they would not want to."
    In the meantime, everyone waits, starting Monday morning, when the Supreme Court is next scheduled to release rulings. With so much uncertainty, even Perry and Stier have decided to plan "something very intimate" for a wedding because the Supreme Court has made planning a larger ceremony difficult.
    "We think about it all the time," Perry said this week. "It's getting so close now. Mondays in June are now all possible days."
