A long opinion from the district court in La Unión Del Pueblo Entero v. Abbott is here. Several portions of SB1 relating to mail-in voting and voter assistance were found to violate the Americans with Disabilities Act and the Rehabilitation Act. (There have been other legal issues previously adjudicated in this complicated case.) There are a lot of parties, a lot of sections of the bill in dispute, and a lot of subtlety in which parts are or are not enjoined, but it is mostly a win for the plaintiffs–for more, dig into the opinion.
