Prop 8 outlawed gay marriage in California after it had been passed. Federal Appeals Judge Vaughn Walker had ruled the same way nearly two years ago in initially overturning the Proposition which was enacted by popular vote.
Opponents say that Prop 8 violates the Equal Protection Clause of the U.S. Constitution. Proponents say that the will of the people of California was to ban gay marriage in the state.
Now that the Ninth Circuit Court has ruled, this is sure to go to the U.S. Supreme Court for a final decision. If it survives the test there, any attempts by states to outlaw and ban gay marriage in the United States would likely go by the wayside due to precedent.
The Supreme Court could also decline to hear the case and let the Ninth Circuit's 2-1 decision to stand.
It's another victory for marriage equality! It's time.
