Massachusetts's supreme court is running away and deliberately and with premeditation (and not to mention conspiring with one party to the lawsuit) denying the People of Massachusetts a republican form of government as required by Article IV of the United States Constitution, and there is no federal issue here?
Try your pabulum on infants who don't know what the issues are.
I was trying to show an argument the Federal courts would be likely to use. If the SJC justices of MA were lawfully appointed and confirmed under the MA constitution, I cannot see the Federal judiciary wanting to become involved in interpreting that constitution.
It's a little hard for the Federal court system to condemn judicial activism when they are the most flagrant users of it.
