WHAT LAW???????
Precisely. This is explicitly NOT established law. The SC interpreted an appealed finding of a lower court that applies to 2 jurisdictions. It has absolutely no binding effect beyond that limited application. The insistence upon treating SC findings as established law is not found in the constitution.
It's worse than that.
Under the status quo, USSC decisions are regarded by the ruling class as CHANGING the Constitution. They are not mere "laws" passed (or proclaimed) without authority, they are actual Constitutional Amendments, and, unlike Article V amendments, they don't even require ratification.
The contradictions of this process will, eventually, bring down the state.
