“Under the Commerce Clause, the feral givernment preempts states in workplace safety. Therein OSH Act is a provision that the Sec’y of Labor may protect workers against “grave dangers” that exist in the workplace through emergency rulemaking.”
And Biden with his OSHA mandate is attempting to nullify the Civil Rights Act of 1964, the holy grail for liberals. The civil rights act is legislation created by Congress. A president or executive agency can’t magically cancel or alter a law passed by congress with an order.
Go read Rapanos v US or SWANNC v US. In both cases, executive agencies tried to redefine what a navigable body of water is. The USSC ruled that the agencies exceeded their authority.
Unfortunately ... it takes a lot of money to fight the federal givernment agencies on their unlawful actions. That is also why they get away with a lot of this stuff.
