Can You Appeal a Denial of a Motion to Dismiss? The Federal Exceptions

Can you appeal a denial of a motion to dismiss? Generally, no, not until final judgment. In federal court a denied motion to dismiss is an interlocutory order, and appeals run from final decisions, so you litigate on and challenge the denial after judgment. A short list of exceptions lets some denials go up early. The mistake to avoid is assuming your ruling is on that list when it is not.

Can you appeal a denial of a motion to dismiss before judgment?

The courts of appeals have jurisdiction over "appeals from all final decisions of the district courts." 28 U.S.C. § 1291. An order that leaves the case pending is not a final decision. When a judge denies a motion to dismiss, nothing has ended: discovery opens, the defendant answers, and the case moves toward trial.

That is not a forfeiture. If you preserved the objection, the denial is usually reviewable later, together with the final judgment. The question is whether any route gets you there sooner. There are four, each with its own conditions.

Route one: § 1292(b) certification

This is the exception available to the widest range of litigants, and it has two gates. The district judge goes first. Section 1292(b) applies when the judge is "of the opinion that such order involves a controlling question of law as to which there is substantial ground for difference of opinion and that an immediate appeal from the order may materially advance the ultimate termination of the litigation," and the judge "shall so state in writing in such order."

Then the court of appeals may, "in its discretion, permit an appeal to be taken from such order, if application is made to it within ten days after the entry of the order." Two consequences follow.

• The 10 days start at the certifying order. If the judge certifies in a later amended order, the time runs from that amended order. FRAP 5(a)(3) says the district court may amend its order to include the required statement and "the time to petition runs from entry of the amended order."
• The case does not pause. Under the statute, the application "shall not stay proceedings in the district court unless the district judge or the Court of Appeals or a judge thereof shall so order."

Practically, you ask the district judge for certification in a short motion, often paired with a request to stay. The statute sets a high bar: the question must be a controlling question of law, genuinely contestable, and one whose immediate resolution may materially advance the case. A fact-bound argument that the complaint is thin will not qualify. A clean legal question about, say, whether a statute creates a private right of action can.

Certification is also the only early route for many denials discussed below, including personal jurisdiction. The circuits describe 1292(b) standards in slightly different words, so read your own circuit's cases before drafting the motion.

Route two: the collateral-order doctrine

Section 1291 has been read to reach a "small class" of orders that, in the Court's words, "finally determine claims of right separable from, and collateral to, rights asserted in the action, too important to be denied review and too independent of the cause itself to require that appellate consideration be deferred until the whole case is adjudicated." Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541 (1949).

The Court has kept the class small and has said the class of collaterally appealable orders must remain "narrow and selective in its membership." Mohawk Industries, Inc. v. Carpenter, 558 U.S. 100 (2009). For denials of motions to dismiss, three categories matter.

Qualified immunity. "[A] district court's denial of a claim of qualified immunity, to the extent that it turns on an issue of law, is an appealable 'final decision.'" Mitchell v. Forsyth, 472 U.S. 511 (1985). The reasoning is that qualified immunity is an immunity from suit, "effectively lost if a case is erroneously permitted to go to trial." The Court applied this in Ashcroft v. Iqbal, 556 U.S. 662 (2009), reiterating that an order rejecting qualified immunity at the motion-to-dismiss stage is a final decision within the meaning of § 1291. The "issue of law" limit is real. A defendant may not appeal a summary-judgment order "insofar as that order determines whether or not the pretrial record sets forth a 'genuine' issue of fact for trial." Johnson v. Jones, 515 U.S. 304 (1995).

Eleventh Amendment immunity. "States and state entities that claim to be 'arms of the State' may take advantage of the collateral order doctrine to appeal a district court order denying a claim of Eleventh Amendment immunity." Puerto Rico Aqueduct & Sewer Authority v. Metcalf & Eddy, Inc., 506 U.S. 139 (1993). This is the state-defendant version of the qualified-immunity rule. Whether a particular entity is an "arm of the State" is the contested question, and circuits apply different multi-factor tests.

Double jeopardy (criminal cases). The Court held that "pretrial orders rejecting claims of former jeopardy, such as that presently before us, constitute 'final decisions' and thus satisfy the jurisdictional prerequisites of § 1291." Abney v. United States, 431 U.S. 651 (1977). This reaches a defendant whose motion to dismiss an indictment on double jeopardy grounds was denied. It does not make other denied motions to dismiss in a criminal case appealable.

What is not appealable now

Each ruling below is generally reviewable only after final judgment, or through § 1292(b) if the judge certifies.

On forum-selection clauses, the Court held that an order denying a motion to dismiss on that basis is not immediately appealable under § 1291 as a collateral final order. Lauro Lines s.r.l. v. Chasser, 490 U.S. 495 (1989). The right to be sued only in a particular forum is "adequately vindicable" after final judgment, "surely as effectively vindicable as a claim that the trial court lacked personal jurisdiction over the defendant."

On forum non conveniens, the Court held that neither a denial of a motion to dismiss on the ground that an extradited person is immune from civil process, "nor an order denying a motion to dismiss on the ground of forum non conveniens, is a collateral order subject to appeal as a final judgment under 28 U.S.C. § 1291." Van Cauwenberghe v. Biard, 486 U.S. 517 (1988). The Court observed that such determinations are not completely separate from the merits.

Personal jurisdiction deserves a plain statement. A defendant who loses a Rule 12(b)(2) motion is not on the collateral-order list. That defendant either seeks § 1292(b) certification or preserves the objection and appeals after judgment. Check your own circuit's decisions on the point before you rely on it in a filing.

Rule 54(b) is not an exception either. It lets a court enter final judgment on a claim or party it has fully resolved, which happens after a partial grant. A denial resolves nothing, so there is nothing for Rule 54(b) to certify.

Route three: § 1292(a)(1) injunction orders

Section 1292(a)(1) opens appeals from interlocutory orders "granting, continuing, modifying, refusing or dissolving injunctions." A denied motion to dismiss is not one of those. The route matters only when the same ruling also grants or refuses injunctive relief, as when a court denies dismissal while entering a preliminary injunction. In that case the appeal is from the injunction order, and the court of appeals may reach the legal questions the injunction depends on. If you think a dismissal ruling has the practical effect of an injunction, find your circuit's authority before relying on that theory.

Route four: mandamus

Mandamus is a petition to the court of appeals asking it to correct a ruling, not an appeal. The Supreme Court describes it as available "in extraordinary circumstances" where an order amounts to "a judicial usurpation of power or a clear abuse of discretion." Mohawk, 558 U.S. 100. A wrongly denied motion to dismiss rarely meets that standard. Treat mandamus as a last resort.

State court is different

Everything above is federal. State systems set their own interlocutory rules, and the differences are large.

• New York. CPLR 5701 allows appeal as of right to the Appellate Division from an order that "involves some part of the merits" or "affects a substantial right," among other grounds, and permissive appeals under 5701(c) with leave.
• California and Texas. Both states route some interlocutory challenges through writs or specific statutes. Check the current code sections and the local appellate rules before assuming a denial can or cannot be appealed.

Preserve the issue and calendar the clocks

A denied motion to dismiss is a preservation problem as much as an appeal problem. Four steps cover most of it.

1. Make the record. File the motion on the specific ground, get a written ruling, and keep the order. Plead the defense in your answer.
2. Calendar the 10 days immediately if you want § 1292(b). The clock starts at the certifying order, so calendar both a motion to certify and the petition deadline.
3. Calendar the 30-day notice of appeal for a collateral-order appeal. Under FRAP 4(a)(1), the notice is due "within 30 days after entry of the judgment or order appealed from," and 60 days when the United States or a federal officer is a party. A criminal defendant appealing a double jeopardy denial has 14 days under FRAP 4(b)(1)(A).
4. Consider reconsideration first, but count the days. Do not assume a motion for reconsideration buys time. The court of appeals cannot extend the time to petition for permission to appeal (FRAP 26(b)(1)), and FRAP 4(a)(5) extends a missed notice-of-appeal deadline only on a motion filed within 30 days after it expires, for excusable neglect or good cause.

If you defeated the motion, the same map shows what to expect: your opponent's early-appeal options are these four routes. For the opposition itself, see how to respond to a motion to dismiss.

Frequently asked questions

Can you appeal a denied motion to dismiss right away?

Usually not. In federal court a denial is an interlocutory order, and appeals lie from final decisions under 28 U.S.C. § 1291. The exceptions are narrow: a certified appeal under § 1292(b), the collateral-order doctrine for qualified immunity, Eleventh Amendment immunity, or double jeopardy, and rarely mandamus.

How long do you have to ask for a 1292(b) interlocutory appeal?

Ten days. Under 28 U.S.C. § 1292(b), the district judge must first state in writing that the order involves a controlling question of law, and the court of appeals can accept the appeal only if the application is made within ten days after entry of that order. Filing the application does not stay the case unless a judge orders it.

Is a denial of a motion to dismiss for lack of personal jurisdiction appealable?

Not by itself. A denial on personal jurisdiction, venue, a forum-selection clause, or forum non conveniens is not a collateral order, so you ordinarily raise it on appeal after final judgment. The Supreme Court so held for forum-selection clauses in Lauro Lines and for forum non conveniens in Van Cauwenberghe. Section 1292(b) certification remains possible.

Can a qualified immunity denial be appealed before trial?

Yes, to the extent it turns on an issue of law. Mitchell v. Forsyth held that such a denial is an appealable final decision, and Ashcroft v. Iqbal applied that rule to a denial at the motion-to-dismiss stage. A denial that decides only that the evidence presents a genuine fact dispute is different: Johnson v. Jones held that kind of order is not immediately appealable.

What happens if you do not appeal a denied motion to dismiss now?

The objection usually survives if you preserved it. You litigate the case, and if you lose at final judgment you appeal both the judgment and the earlier denial, with a notice of appeal due within 30 days of entry of judgment in a civil case (60 if the United States is a party). Immunity from suit is the exception: qualified immunity is effectively lost if the case is wrongly allowed to go to trial. Some grounds, like lack of subject-matter jurisdiction, can be raised at any time.

Before you file the certification motion

A § 1292(b) motion lives or dies on the case law, because the whole argument is that the legal question is open and contested. Pull your circuit's certification and collateral-order decisions with CaseRead's research chat, which answers from CaseRead's public law database and the matter's own files, and put the 10-day and 30-day dates on the matter's deadlines. Then cite-check the brief before it goes out. The free Hallucination Shield needs no signup, checks up to 50 citations per run, and flags any it cannot verify. A motion arguing that a legal question is genuinely contested is the wrong place for a citation that does not exist.
