I posted awhile ago on the Amtrak forums that the mask mandate for vaccinated travelers and those with antibodies who had the virus before is absolutely ridiculous and Senator Rand Paul proposed a bill for such in congress. Unfortunately it seems unlikely to pass. Hopefully the SCOTUS will be receptive to the arguments. I personally have avoided taking the train and flying due to the mask mandates. I am hoping this will be changed in the foreseeable future.
I
personally would love for the broad mask mandate on interstate & public transportation to be lifted, BUT:
1) there's evidence that having antibodies from being exposed to Covid does
not convey the same protection as being fully vaccinated.
2) I say "broad" to refer to requiring masks regardless of vaccination. I would have no problem having to show my vaccination card or a photograph of it as a condition of traveling Amtrak (or an airliner or intercity bus) without a mask and crews booting off maskless passengers who can't show proof of vaccination. In other words, "vaccinated need not mask, unvaccinated must mask" like a lot of store signs
say, but with real "teeth". I also have no problem with a broad mask mandate on public transit for the time being because enforcing an "unvaccinated must mask" rule is effectively impossible on a transit bus or light rail train and highly inconvenient at best on a commuter train.
3) I
really don't relish the idea of SCOTUS or another court striking down the mask requirement.
The authority of the Federal government over interstate transportation is broad, as it its authority to impose conditions on transit systems that accept Federal funding (which is essentially all of them). Courts don't find statutes or regulations invalid just because someone believes them to be imprudent or excessive or a "bad idea"; that's an argument for the body that imposed the regulation to repeal it, or to Congress to override the regulation by statute. Unless you're talking about either a fundamental right (free speech, religion, etc.) or discrimination on race, ***, religion, etc. grounds, a government regulation with authority and
any rational basis survives judicial review.
The fact that there's a population that at the moment
can't be vaccinated -- children under 12 -- sure sounds like a rational basis to me. Whether you personally feel that's enough is irrelevant, if any rational person can make a rational argument for it, it's not legally invalid. Again, if you think a regulation is a bad idea but it has authority and a rational basis, your argument that it's a bad idea has to be "pitched" to the President or the Dep't of Transportation, or maybe Congress, but not the courts.
SCOTUS ignoring all that and striking down the interstate/public transport mask mandate (which I consider unlikely for the reasons just stated) would IMHO be a political decision rather than a constitutional or legal decision, and the shenanigans that would be caused in various fields of governance and politics by SCOTUS acting like a super-legislature rather than a court in such an egregious manner more than outweigh (understatement!) any momentary comfort I would get by not having to wear a mask on a train.
