National Park Service v. National Trust for Historic Preservation in the United States · ¶17

Start with this. The district court likely exceeded its Article III authority to enjoin the activities of a coordinate branch of government. Cf. Trump v. CASA, Inc., 606 U. S. 831, 859 (2025). And courts may not exceed the bounds of their lawful authority simply because they may think another branch has exceeded its own. See Lujan, 504 U. S., at 560 (Article III’s standing requirements help define “those disputes which are appropriately resolved through the judicial process” rather than in the political arena (internal quotation marks omitted)); Alliance, 602 U. S., at 379 (federal courts do not “operate as an open forum for citizens to press general complaints about the way in which government goes about its business” (internal quotation marks omitted)).
