Supposedly, the MA Supreme Court has put the legislature in a box, saying that they must change the laws to allow Gay marriage by May, knowing that an amendment could not be passed in time to stop it.
The person who wrote Derb suggested that the legislature could pass a law temporarily stopping all new marriage licenses in Massachusettes. That would not violate the equal protection clause of the MA constitution, and would allow there to be enough time for an amendment to be argued and either enacted or rejected.
In the interim, hetero couples who wanted to get married could go to NH or such to get hitched.
