Cite as: 585 U. S. ____ (2018) 13 Opinion of the Court an interlocutory injunction is improperly granted or denied, much harm can occur before the final decision in the district court. Lawful and important conduct may be barred, and unlawful and harmful conduct may be allowed to continue. Recognizing this, Congress authorized interlocutory appellate review of such orders. But if the availability of interlocutory review depended on the district court’s use of the term “injunction” or some other particular language, Congress’s scheme could be frustrated. The harms that Congress wanted to avoid could occur so long as the district court was careful about its terminology. The “practical effect” inquiry prevents such manipulation. In analogous contexts, we have not allowed district courts to “shield [their] orders from appellate review” by avoiding the label “injunction.” Sampson v. Murray, 415 U. S. 61, 87 (1974). For instance, in Sampson, we held that an order labeled a temporary restraining order (which is not appealable under §1292(a)(1)) should be treated as a “preliminary injunction” (which is appealable) since the order had the same practical effect as a preliminary injunction. Id., at 86–88. Appellees and the dissent contend that the “practical effect” approach should be confined to §1292(a)(1), but we see no good reason why it should not apply to §1253 as well. Appellees note that we “narrowly constru[e]” §1253, Goldstein v. Cox, 396 U. S. 471, 478 (1970), but we also construe §1292(a)(1) “narrowly,” Carson, supra, at 84. In addition, the relevant language in the two provisions is nearly identical;10 both provisions serve the same purpose; and we have previously called them “analogous.” Goldstein, supra, at 475. —————— 10 In relevant part, §1253 applies to “an order granting . . . an inter- locutory . . . injunction.” Section 1292(a)(1) applies to “[i]nterlocutory orders . . . granting . . . injunctions.” Although the similarity is obvious, the dissent perceives some unspecified substantive difference.
