Case 1:20-cv-03325-AT Document 43 Filed 05/05/20 Page 13 of 30 III. Preliminary Injunction A. Legal Standard A preliminary injunction sought against government action taken pursuant to a statute or regulatory scheme requires that “the moving party . . . demonstrate (1) irreparable harm absent injunctive relief, (2) a likelihood of success on the merits, and (3) public interest weighing in favor of granting the injunction.” Friends of the E.

This standard also applies where the injunction “will provide the movant with substantially all the relief sought and that relief cannot be undone even if the defendant prevails at a trial on the merits.” People ex. rel.
