General Discussion

It was procedural - only about whether a federal district court could issue a nationwide injunction. The plaintiffs in this case were challenging Trump's EO attempting to limit birthright citizenship, and SCOTUS said the injunction could be upheld only for these plaintiffs. Other people wanting to challenge the EO would have to do so themselves or by class action. The decision also applies to cases before the asshole judge in Texas who's been trying to limit abortion rights nationally.
