The U.S. Ninth Circuit Court of Appeals (a higher, federal court; not a California state court) has issued a ruling upholding an earlier lower court ruling which found that Proposition 8 was and is unconstitutional. Prop 8, as you may recall, was the 2008 ballot initiative which banned same-sex marriage in the state of California, after marriage equality had been legalized by the California Supreme Court.
This ruling by the Ninth Circuit Court is
profound, to put it lightly, and very good news for equality. The judges ruled that Prop 8 indeed violated the Equal Opportunity Clause of the U.S. constitution, unfairly targeting a minority group, i.e. gay and lesbian Californians.
If the court-ordered stay is lifted within fourteen days (per the release of the official mandate), it would mean that marriage equality will return to California immediately. If the opposition appeals again, however, to the U.S. Supreme Court, the stay on marriages will remain in place until the issue is resolved.
It is truly amazing news for equality, and a same-sex marriage case will likely eventually end up in the U.S. Supreme Court. Due to the U.S. Supreme Court's influence, a ruling for marriage equality may have a very positive reverberation in courts around the world, including in the Philippines, whose constitution also has a clear-cut Equal Opportunity Clause borrowed almost directly from the U.S. Constitution's.
