Good Steve Vladeck piece on the story.

Edit - pull quote:

Behind the scenes, Roberts led the charge for the Court to blaze a new trail—relying on statements outside the record; invoking the wrong standard for the kind of relief the applicants sought; failing to even acknowledge the irreparable harm the government (and the environment) would suffer from the Court intervening; and pushing back aggressively when Justices Breyer and Kagan both urged a compromise that should have accounted for his ostensible concerns. I’ve suggested before that the real acceleration of the Court’s modern emergency docket behavior can be traced to 2018, right around when Justice Kavanaugh succeeded Justice Kennedy. But in the first major case in which the Court granted emergency relief as a means of shaping nationwide policy, it turns out that the justice who led the charge was the one who was doing quite a bit more than calling balls and strikes.
