The SJC is not an all-powerful branch designed to supersede the other two.
It’s about damn time some politician with a set of cojones instruct the sheeple about this “discovery”.
Sign what law? Have you read the court decision? Until you do, I suggest that you stop buying into the pre-digested spin spewed forth by WND.
It wasn't the SCJ superceding the "other two", it was the SCJ interpreting the legal definition of "civil marriage" and the Legislature agreeing with their interpretation of existing law.
