That’s exactly what I expected them to do. The know that they would get their pee pee’s whacked by the SCOTUS before the ink was dry on any sort of intervention.
From the article:
In a statement, Hawaii Attorney General Douglas Chin said the ruling "makes clear that Judge Watson does possess the ability to interpret and enforce the Supreme Court's order, as well as the authority to enjoin against a party's violation of the Supreme Court's order placing effective limitations on the scope of the district court's preliminary injunction."
I haven't read either opinion yet (District Court or 9th Circuit), but if Chin's remark is accurate, my take is that the 9th Circuit just doesn't want to go out on that limb by itself. It would be happy to go out on that limb with the District Court.
