I'd add "on an emergency temporary basis." That's the "grave danger" level of risk. OSHA regular rules don't require that level of risk.
The same "OSHA mandate" issue can come through the courts again - this time involving District Courts - is OSHA proceeds to implement the rule after the period for public comment.
I understand that the SCOTUS opinion is on a "stay" or "injunction" basis, and too that the opinion reads as though OSHA lacks this power, period. Won't be the first time the government rebooted an arguably incorrect/illegal/unauthorized order against the public in the face of what looks like court opposition. I doubt the court is really opposed. All it is concerned with is institutional legitimacy and maintenance of federal powers.
That’s right. The public comment period is actually still open on that standard rule. That closes on the 19th.
However, it usually takes years to implement a final rule, at which point we should be all past this nonsense.
