In their *unanimous* ruling they slammed the Massachusetts Supreme Court mercilessly...making it clear that its argument was truly frivolous (IIRC they used that exact word).
That ruling makes me optimistic regarding the outcome of *this* case.
Anyone interested can look up "Caetano v Massachusetts"...IIRC it was decided last year.
Very important. And, I hope one more liberal, judicial activist member of SCOTUS retires soon. A 6-3 or higher decision would be monumental.
