Honest answer: we don’t fucking know. The discarding of Chevron, coupled with the determination a rule may be challenged from the moment of harm and not from the moment the rule was made, throws more or less the entirety of administrative law - the basis of a regulatory system - into flux.
Administrative law, while affecting the most (child car safety seats, maternity room cleanliness standards, cleaning chemicals allowed), isn’t on the bar exam, so…
Honestly, the only thing we can hope for is a particularly vengeful Democrat to use this change as a legal blunt weapon to scare them into reversing it, but that involves them actually doing something in the first place and the other side not retaliating.
Like, when I say the impact of the last week of rulings can’t be understated, I mean it because Chevron was like…a foundational thing for administrative law for the last four decades.
From past experience, how major SCOTUS rulings will affect legal office staff:
They should prepare for at least one attorney in the office to be more abusive than usual & behave like a small child whose favorite toy has been taken away because they won't stop hitting other kids with it.

There’s a chance the lower courts look at “this regulation existed before the company did” and rule that it’s akin to coming to the nuisance and can’t grant standing.
It’s not that we know nothing is solid anymore, it’s that we don’t know what *is* still solid.
