28 USC 1292: Interlocutory Appeals, Injunctions, and Certification

Under 28 U.S.C. § 1292, interlocutory appeals let a party challenge certain pretrial orders before the case is over. Three categories of orders can be appealed as of right — injunctions, receiverships, and certain admiralty rulings — and other orders can be reviewed if the district judge certifies a controlling question of law and the court of appeals agrees to take it.¹

Why Most Pretrial Orders Cannot Be Appealed Right Away

Federal appellate courts normally have jurisdiction only over “final decisions” of the district courts under 28 U.S.C. § 1291.² That is the final judgment rule. A ruling on a motion to dismiss, a discovery order, or an evidentiary decision usually has to wait until the trial court has resolved every claim in the case.

Some pretrial orders cause harm that cannot wait. A preliminary injunction can shut down a business overnight. A receivership can strip an owner of control before anyone has proven anything at trial. Section 1292 identifies the orders serious enough to justify appellate review while the case is still going on, and sets the procedure for getting that review.

Orders You Can Appeal As of Right

Section 1292(a) lists three categories of pretrial orders that can be appealed immediately without any special permission from the trial judge. If the order fits, the court of appeals must take jurisdiction.

Injunctions

Section 1292(a)(1) covers orders granting, denying, modifying, or dissolving injunctions.³ Because an injunction can reshape the parties’ positions before any trial, Congress made these rulings immediately reviewable.

Not every order touching on injunctive relief qualifies. In Carson v. American Brands, Inc., 450 U.S. 79 (1981), the Supreme Court held that an order can be appealable even if it does not use the word “injunction,” so long as it has the practical effect of granting or refusing one. The party appealing must show the order could have “serious, perhaps irreparable, consequences” and that immediate appeal is the only effective way to challenge it.⁴ An order that merely delays injunctive relief or schedules further proceedings does not clear that bar.

Receivership Orders

Section 1292(a)(2) allows appeals from orders appointing receivers, refusing to appoint them, or declining to wind up an existing receivership.³ A receiver is a neutral party the court puts in charge of managing assets, and appointing one effectively takes control away from the current owner. Refusing to appoint one, on the other hand, can let assets disappear before judgment. Either ruling can permanently shape the case, which is why the statute treats them as appealable now rather than later.

Admiralty Decisions on Rights and Liabilities

Section 1292(a)(3) covers interlocutory orders in admiralty cases that determine the rights and liabilities of the parties.¹ The order has to resolve a substantive question. An order deciding which party bears liability for a collision qualifies. An order ruling on the admissibility of an expert’s testimony does not.

Certified Appeals Under Section 1292(b)

If a pretrial order does not fit one of the three categories above, you can still ask for interlocutory review, but the path is harder. Section 1292(b) lets the district judge certify an order for appeal when three conditions are all met: the order involves a controlling question of law, there is substantial ground for disagreement about the answer, and an immediate appeal could materially advance the ultimate termination of the litigation.³

Each requirement is doing real work. A “controlling question of law” means a pure legal question whose answer could change or significantly redirect the case. The Seventh Circuit in Ahrenholz v. Board of Trustees, 219 F.3d 674 (7th Cir. 2000), explained that appellate judges should be able to resolve the question “quickly and cleanly without having to study the record,” which is impossible if the issue is tangled up with disputed facts.⁵ Disputes about whether summary judgment was properly denied on the facts do not qualify.

“Substantial ground for disagreement” typically means a genuine split in the case law or a novel question courts have not clearly answered. “Materially advance” asks whether the appeal would shorten the case as a whole, not just resolve one disputed issue.

Certification is only permission to ask. Even after the district judge certifies, the court of appeals decides independently whether to hear the case, and most circuits accept only a fraction of the petitions they receive.

Filing a Section 1292(b) Petition

The window is short. A party has ten days after the district court enters its certified order to file a petition for permission to appeal with the court of appeals.¹ Missing that deadline ends the interlocutory route, no matter how strong the underlying argument is.

The petition follows Federal Rule of Appellate Procedure 5. It must include the facts needed to understand the legal question, the question itself, the relief sought, the reasons the appeal should be allowed, and a copy of the district court’s order along with any related opinion.⁶ A petition prepared on a computer cannot exceed 5,200 words. A handwritten or typewritten petition cannot exceed 20 pages.

Filing a petition does not stop the district court case. The statute is explicit: proceedings continue unless the district judge or the court of appeals orders a stay.³ A party pursuing a Section 1292(b) appeal may be preparing for trial and briefing the petition at the same time.

What the District Judge and Appellate Court Each Decide

The district judge is the first gatekeeper for Section 1292(b) appeals. The certification has to be in writing and has to state that the order involves a controlling question of law with substantial ground for disagreement and that immediate appeal may materially advance the case. A vague certification makes the appellate court’s job harder and reduces the chance the petition will be granted.

The district judge (or the court of appeals) also decides whether to stay proceedings while the appeal is pending. The Supreme Court in Nken v. Holder, 556 U.S. 418 (2009), identified four factors: likelihood of success on the merits, irreparable injury without a stay, harm to the opposing party from a stay, and the public interest.⁷ Stays are granted sparingly because they delay resolution for the other side.

Once the petition reaches the court of appeals, that court independently determines whether it has jurisdiction and whether the case is worth taking. Even orders that seem to fit the statute get a fresh look. If jurisdiction is lacking, the appeal is dismissed without any decision on the merits.

Specialized Courts: Section 1292(c) and (d)

The statute has two provisions for specialized federal courts. Section 1292(c) gives the Federal Circuit exclusive jurisdiction over interlocutory appeals in cases that would otherwise go to that court, including patent infringement judgments that are final except for an accounting.¹ Section 1292(d) applies the same certified-appeal framework to the Court of International Trade and the Court of Federal Claims, with the same controlling-question standard and the same ten-day filing window.

If the Court of Appeals Refuses to Hear the Appeal

A denial does not kill the underlying legal argument. The party can raise the same issue after final judgment through a normal appeal under Section 1291, and the appellate court is free to reach a different conclusion once it has a full record.

The immediate cost is practical. If the district court was not stayed, both sides have been litigating on two fronts and spending money on trial preparation while the petition was pending. If it was stayed, the case has been on pause for months with nothing to show for it. That is why experienced litigators think carefully before filing. The petition needs to be worth the disruption even if it fails, and most do fail.

Related Routes That Are Not Section 1292

Two other doctrines produce pretrial appeals but are separate from Section 1292.

The collateral order doctrine, from Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541 (1949), treats certain pretrial orders as effectively final for appeal purposes.⁸ An order qualifies only if it conclusively determines the disputed question, resolves an important issue completely separate from the merits, and would be effectively unreviewable after final judgment.⁹ Denials of qualified immunity for government officials are the classic example. The Supreme Court has repeatedly declined to expand the doctrine.

Federal Rule of Civil Procedure 54(b) offers another route in cases with multiple claims or parties. The district court can enter a final judgment on some claims while the rest of the case continues, provided the court expressly determines there is “no just reason for delay.”¹⁰ Those resolved claims become appealable under Section 1291. Technically that is not an interlocutory appeal at all, but it achieves the same practical result.
