And the APA passed in 1946. What you are pointing to is regulation. And Chevron was overturned recently. There is no jurisdiction review bar for PERM. I am willing to bet actual money that MS will win at trial or it will be settled out of court like everything else.
Again, I am not following, are you now saying that the debarment list for PERM does not exist or it's unlawful and will be overturned by courts any moment now, 19 years later? Well, as you said, nobody is going to debar you from smoking hopium and copium.
The present unilateral action of banning MS from using PERM is unlawful as MS hasn't broken any laws. (PERM has its own cooldown mechanism of timeouts after layoffs. I'm not talking about those.) If the US government bars MS on any grounds of fraud, abuse, misrepresentation, etc., or if the US government tries to claim that they have the power to unilaterally ban PERM for MS, they will lose in court or settle. We can revisit this in a few months.
Good, now you went from the "There is no such thing as a legal blanket ban. The executive does not have the authority to do any of this." to "MS will settle". It sure will, as all other targets of this action.
Courts deal with live controversies, they do not rule on abstract things. So, if the case moves to trial, the court will rule that there is no such thing as a legal blanket ban as enacted here. As for settling, you can go back to the top of the thread where I claim that there is no successful prosecution. If you think that is a win, more power to you. I get the feeling that we have been in agreement the whole time. Make noise -> shakedown -> press release -> settle is what happens always. I count that as 'no successful prosecution', and you count that as a win.
You keep saying "case", "trial" as if there is an actual lawsuit or indictment being discussed here. Has MS lodged a lawsuit? If so, I'd love to see it and if not - what are you talking about?
Ya, dude, it takes time. Are you unfamiliar with how federal litigation works? So far we have a tweet from the government. They need to put whatever they have concocted in writing and send it to MS. Then MS will file a complaint that shows injury. Or they'll negotiate a settlement even before it goes to trial. And so on. Like I said, we shall revisit in a few months once the dust settles.
So, in other words, no lawsuit, no indictment? Color me unsurprised.
