No, I never implied that they fail. They do not prosecute or deny any PERM certifications. PERM is anyway not tied to inadmissibility of an alien as PERM is an employer driven certification process. Recall that PERM is administered by the Dept. of Labor. Specifically for PERM, they need to prove in a court of law that the company is violating civil rights, labor laws, discriminating against a protected class, doing fraud, etc. They do not do that at the administrative level (by denying PERM) or at the judicial level (by winning a court case). All they do is make speeches on the campaign trail, and occasionally settle out of court as some other sibling comments' examples in Apple, META, etc. show.
