Subject: Re: A Win For Texas
Seems the SCOTUS didn't approve the law, but just didn't want to get into the administrative issues that are the purview of the lower courts?

Yes. The merits of the law were not at the SCOTUS. They were only debating whether there should be an administrative stay during the pendency of the Fifth Circuit's review of the preliminary injunction. These are debates over whether a preliminary ruling should go into effect during the pendency of the appeal of that preliminary ruling - not the merits of the underlying case.
