You can find the careful and well reasoned district court opinion at this link. From the introduction:
The first question presented in these consolidated cases is whether the President, acting unilaterally, may direct changes to federal election procedures. Because our Constitution assigns responsibility for election regulation to the States and to Congress, this Court holds that the President lacks the authority to direct such changes.
In Section 2(a) of Executive Order No. 14,248, the President directed the Election Assistance Commission to “take appropriate action” to alter the national mail voter registration form to require documentary proof of United States citizenship. The several Plaintiffs in these consolidated cases have moved for partial summary judgment, arguing that Section 2(a) of Executive Order No. 14,248 cannot lawfully be implemented because our Constitution entrusts Congress and the States—not the President—with the power to regulate federal elections.
Upon consideration of the parties’ submissions, the relevant legal authority, and the entire record, this Court agrees. Because there is no genuine dispute as to any material fact and Plaintiffs are entitled to judgment in their favor on their constitutional separation-of-powers claims regarding Section 2(a) as a matter of law, the Court shall enter partial summary judgment in Plaintiffs’ favor and deny both the Federal Defendants’ and Defendant-Intervenor’s cross-motions for summary judgment as to those claims. The Court shall permanently enjoin the proper Federal Defendants from implementing Section 2(a) of the President’s Executive Order. Because there is no just reason for delaying the ultimate resolution of Plaintiffs’ constitutional separation-of-powers claims regarding Section 2(a), the Court shall enter a final, appealable judgment on those claims. Finally, because Plaintiffs have not alleged that there is yet a final agency action implementing Section 2(a), the Court shall dismiss without prejudice the Democratic Party Plaintiffs’ Administrative Procedure Act claims regarding that provision…
