Yep and it's done at the state level.

I haven't read the court documents...is the argument that states can make these sorts of mandates but the federal government can't? I thought some states were claiming these mandates were illegal at all levels but I can't recall.

The decision seems very well written and is worth at least a skim. The section that answers your question is (f), and starts at the bottom of page 16.

As I read it, the decision says that the State's definitely have the police power to mandate vaccination, and suggests that the federal government lacks this authority under the Commerce Clause (but doesn't directly claim that no other authority exists). The basic claim is that OSHA, given it's current legal authority, lacks the right to regulate "noneconomic nonactivity".

I very much appreciate you writing it out like that. I will read it over. Again, thank you
