I quoted the Opinion for your benefit as you apparently had not read it. I didn't need to spin it.
If you were to read the Opinion, you would see that by upholding the injunction for all complainants and those similarly situated, the clear signal the Court transmitted is that it does not accept the government's argument that 8 U.S.C. § 1182(f) combined with Mandel gives the President the authority to bar entry of any non-criminal class of people merely by uttering the words “national security” as a blanket “facially legitimate and bona fide reason” that thereby prevents the Court from “look[ing] behind the exercise of discretion”. This was the government's one and only argument, and it wasn't presented until the case got to the Fourth Circuit. When the Supreme Court begins to “look behind” the reasons for the EO, at least some of the Justices will find, just as those on the Fourth Circuit found, that the travel ban would not have prevented any terrorist act to date, would not have barred entry to any of the 9/11 hijackers, and that Christian-majority countries such as Venezuela and the Philippines were not included despite being “significantly compromised by terrorist organizations, or contain[ing[ active conflict zones,” and being unwilling or unable “to share or validate important information about individuals seeking to travel to the United States”. They might find that the various reports the EO mandates were not even written. I have no doubt that at least some on the Court will want to apply the Lemon test, which is likely to leave a bitter aftertaste in someone's mouth.
BTW, assuming that Justice Kennedy votes with the majority in this case, the opinion will be his to author--he delivered Din, and the Per Curiam certainly sounds like his writing. So perhaps he's planning to hang around at least for the next term.
