Opinion of the Court
on the merits. See, e.g., Mazurek v. Armstrong, 520 U. S. 968, 972 (1997) (per curiam); Doran v. Salem Inn, Inc., 422 U. S. 922, 931 (1975). The Government argues that the District Court lost sight of this principle in issuing the injunction based on a mere tie in the evidentiary record.
A majority of the en banc Court of Appeals rejected this argument, and so do we. Before the District Court, the Government conceded the UDV's prima facie case under RFRA. See 282 F. Supp. 2d, at 1252 (application of the Controlled Substances Act would (1) substantially burden (2) a sincere (3) religious exercise). The evidence the District Court found to be in equipoise related to two of the compelling interests asserted by the Government, which formed part of the Government's affirmative defense. See 42 U. S. C. §2000bb–1(b) ("Government may substantially burden a person’s exercise of religion only if it demonstrates that application of the burden to the person—(1) is in furtherance of a compelling government interest . . ." (emphasis added)); §2000bb–2(3) (“[T]he term 'demonstrates' means meets the burdens of going forward with the evidence and of persuasion"). Accordingly, the UDV effectively demonstrated that its sincere exercise of religion was substantially burdened, and the Government failed to demonstrate that the application of the burden to the UDV would, more likely than not, be justified by the asserted compelling interests. See 389 F. 3d, at 1009 (Seymour, J., concurring in part and dissenting in part) ("[T]he balance is between actual irreparable harm to [the] plaintiff and potential harm to the government which does not even rise to the level of a preponderance of the evidence").
The Government argues that, although it would bear the burden of demonstrating a compelling interest as part of its affirmative defense at trial on the merits, the UDV should have borne the burden of disproving the asserted compelling interests at the hearing on the preliminary
