There is no appeal to ignorance of Article 4, Section 2.They have a right to liberty, a right to call their relationship a marriage, but no legal right to it unless a State changes it Marriage contract legislatively.
I have a feeling that the SCOTUS, based on precedent, will disagree.
I have a feeling we are getting the "nobody wins" result. States cannot be forced to change the marriage contract on SSM, but have to recognize duly issued marriage contracts from other States.
Actually, after reading the transcripts of the oral arguments- I suspect it will be all or nothing- if the Court doesn't find for gay marriage, they will not require states to recognize marriage from other states.
The only appropriate ruling based on the Constitution is that gay marriage is not addressed, so they have no basis to rule anything. Take it up with the legislature. Unfortunately, the SCOTUS isn't big on ruling based on the actual law, they prefer to make it
Have you ever wondered what would happen if a bee spit into the wind?
