Background
Five residents living near a New Orleans children’s hospital sued to abate helicopter noise and vibrations after the hospital relocated its helipad from a one-story building to a newly constructed tower in the center of the complex. The plaintiffs sought a mandatory injunction requiring the hospital to relocate the helipad or otherwise abate the noise and vibrations, along with damages for nuisance and negligence.
The district court granted summary judgment in part, holding that Federal Aviation Administration (FAA) regulations preempted any permanent injunction forcing the hospital to move the helipad. The court dismissed certain damage claims but allowed the plaintiffs’ nuisance claims for general damages to proceed to trial. Rather than await trial, the plaintiffs immediately appealed, arguing that the appellate court had jurisdiction to review the district court’s denial of injunctive relief as an interlocutory order under 28 U.S.C. § 1292(a)(1).
The Court’s Holding
The Fifth Circuit dismissed the appeal for lack of jurisdiction. Although the district court’s order had the practical effect of refusing the plaintiffs’ requested permanent injunction, the court held that interlocutory review is available only when the appellant satisfies the stringent test established in Carson v. American Brands, Inc. Under Carson, a party seeking to appeal a nonfinal order that practically denies injunctive relief must demonstrate: (1) that the order “might have a serious, perhaps irreparable, consequence,” and (2) that it may be “effectually challenged only by immediate appeal.”
The court explained that permanent injunctions are final remedies, not interim relief designed to prevent irreparable harm during litigation, and therefore rarely satisfy the Carson factors. Importantly, the plaintiffs never attempted to argue that they met either Carson factor. Additionally, their own conduct undermined any claim of serious or irreparable consequences: they never sought a preliminary injunction, never moved for separate final judgment, never certified an interlocutory appeal under § 1292(b), and never requested expedited trial or review. The court concluded that the plaintiffs would not suffer serious or irreparable harm merely from waiting until final judgment to challenge the order.
Key Takeaways
- Section 1292(a)(1) permits interlocutory appeals of orders explicitly granting or denying preliminary injunctions, but provides narrower access for orders practically denying permanent injunctive relief.
- The Carson two-factor test applies to nonfinal orders that have the practical effect of refusing permanent injunctions, and the burden is on the appellant to satisfy both factors—failure to even attempt this argument is dispositive.
- Failure to seek preliminary injunctive relief or take other interim protective measures strongly suggests the appellant cannot show serious or irreparable consequences warranting interlocutory review.
Why It Matters
This decision clarifies the Fifth Circuit’s stringent approach to interlocutory appeals in cases seeking permanent injunctive relief, particularly when relief is denied through partial summary judgment. The ruling reflects a deliberate policy choice to limit such appeals and avoid premature appellate intervention, distinguishing them from preliminary injunction denials (which are readily appealable). The decision highlights a circuit split: while the Seventh and Ninth Circuits permit interlocutory appeals whenever a permanent injunction is denied, the Fifth Circuit (along with the Second, First, Sixth, Tenth, and Eleventh Circuits) requires satisfaction of the Carson factors.
For litigants seeking review of interlocutory orders denying permanent injunctions, this ruling underscores the importance of: (1) affirmatively seeking preliminary injunctive relief as an interim measure, (2) explicitly arguing irreparable harm, and (3) considering § 1292(b) certification or other procedural mechanisms. The holding reinforces that most disputes over permanent remedies must ordinarily await final judgment, even when the district court has ruled against the requested injunction on the merits.
