Actually, it was in context. A law which is unconstitutional is void as of passage because it can not be valid.
America has always assumed a “Natural Law” which was recognized by the Founders, not created by them.
Google ‘void ab initio’ - you will find it interesting.
No it wasn't. We weren't talking about any unconstitutional laws, and you didn't mention it.
What was being discussed was the "Sovereign Citizen" nonsense, which basically boils down to the silly notion that you can declare yourself sovereign and no longer subject to US law.
"Google void ab initio - you will find it interesting.""
You presume too much.
