RE: Another lesson we MUST learn: the Judicial Branch of the government (SCOTUS) has NO power to make national law.
So, does that mean that the decision to legalize gay marriage by the Kennedy led opinion of the SCOTUS is NOT BINDING on the States?
That is correct.
It is also not binding on the parties of the case because it is patently unconstitutional, thus, invalid and should be ignored as null and void.
