An interlocutory decree is a court order issued during a lawsuit that resolves a specific issue without ending the case. It carries the full force of a court order and can be enforced through contempt, but because it isn’t a final judgment, the issuing court keeps authority to modify it, and the usual rule against mid-case appeals applies with only narrow exceptions. In federal practice, “interlocutory decree” and “interlocutory order” are largely interchangeable, though some state courts still draw distinctions, especially in family law.
What Counts as an Interlocutory Decree
These orders show up in nearly every area of litigation. The most familiar form is the preliminary injunction, where a court tells someone to do something or stop doing something while the case continues. A patent holder might obtain an order halting sales of an allegedly infringing product. A business might be ordered to stop using a former partner’s trade secrets. In divorce cases, courts routinely issue interim orders covering child custody, spousal support, and access to shared bank accounts before the divorce is finalized.
Courts also issue interlocutory orders on procedural matters: the scope of document discovery, whether a case belongs in a particular court, and what evidence will be admissible at trial.1Cornell Law School. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders
A less obvious use arises in bifurcated trials. When a court separates liability from damages, the finding of liability produces an interlocutory decree. The case isn’t over because damages still have to be calculated, but the liability question is resolved. This approach is common in admiralty and complex commercial disputes, where resolving liability first can save enormous time and expense if the defendant is found not liable.
What a Party Must Show to Get One
Getting a preliminary injunction or temporary restraining order isn’t easy. The Supreme Court in Winter v. Natural Resources Defense Council established the standard that federal courts use, and most state courts follow something very similar. A party seeking preliminary relief must satisfy four requirements:
- Likelihood of success on the merits. You need to show a credible chance of winning. Courts won’t freeze someone’s activities on a weak claim.
- Irreparable harm. The harm must be the kind money can’t fix: destruction of irreplaceable resources, disclosure of trade secrets, loss of a unique property interest. The Supreme Court made clear this harm must be likely, not merely possible.2Justia. Winter v. Natural Resources Defense Council, Inc., 555 US 7
- Balance of equities. The court weighs the harm to you if relief is denied against the burden on the other side if it’s granted.
- Public interest. In cases with broader implications, courts consider whether the injunction serves or harms the public. Public health, safety, and free speech interests often come into play.
All four factors matter. A strong showing on one won’t automatically compensate for a weak showing on another. Courts take the analysis seriously because the order restricts conduct before anyone has proven anything at trial.
Orders Without Notice
In rare situations, a court will issue a temporary restraining order without notifying the other side. These ex parte orders exist for genuine emergencies, where even the delay of a phone call to opposing counsel could cause irreparable damage. To get one, the moving party must show through a sworn affidavit or verified complaint that immediate and irreparable harm will occur before the other party can be heard. The attorney must also certify in writing what efforts were made to give notice and why notice should not be required.1Cornell Law School. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders
Judges impose tight limits on this power. An ex parte TRO expires no more than 14 days after entry and can be extended only once for another 14 days if good cause exists or the opposing party consents.1Cornell Law School. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders Protection beyond that requires moving for a preliminary injunction with full notice and a hearing.
Security Bonds
Courts don’t hand these out for free. Under Federal Rule of Civil Procedure 65(c), a court can issue a preliminary injunction or TRO only if the requesting party posts a security bond in an amount the court considers appropriate. The bond compensates the other side if they turn out to have been wrongfully restrained. If a court orders a competitor to stop selling a product and that competitor later wins the case, the bond covers their losses during the shutdown.1Cornell Law School. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders
Bond amounts vary dramatically depending on the stakes. In commercial disputes where halting operations costs millions, expect a substantial bond. In cases involving constitutional rights or public interest litigation, courts sometimes set a nominal amount or waive it entirely. The federal government, its officers, and its agencies are explicitly exempt from the security requirement.1Cornell Law School. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders
How Long They Last and Whether They Can Change
Lifespan depends on type. A federal TRO expires within 14 days unless extended, the shortest-lived form of interlocutory relief.1Cornell Law School. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders A preliminary injunction stays in effect until the court enters a final judgment, which could be months or years away. If the party who obtained the injunction wins at trial, the court can convert it into a permanent injunction as part of the final judgment. If that party loses, it dissolves. Interim orders on procedural matters remain in effect as long as they’re relevant but don’t survive final judgment independently.
Because interlocutory decrees are non-final, the trial court retains authority to modify or rescind them at any time before final judgment. The most common path to modification is changed circumstances. A defendant enjoined from selling a product might present new evidence showing the patent against them is invalid. A party under a temporary support order in a divorce might seek modification after losing a job.
In federal court, motions to reconsider interlocutory orders generally fall under Rule 54(b), which governs non-final orders, rather than Rules 59 or 60, which apply to final judgments.3LII / Legal Information Institute. Federal Rules of Civil Procedure Rule 54 – Judgment and Costs Reconsideration is somewhat easier to obtain for an interlocutory decree than for a final judgment, because review proceeds under the “law of the case” doctrine rather than the stricter post-judgment standards.
Appealing an Interlocutory Decree
The general rule in American courts is that you wait until the case is over to appeal. Interlocutory decrees have several exceptions to that rule, each with different requirements.
Appeals as of Right
Federal law gives appellate courts automatic jurisdiction over certain interlocutory orders. Under 28 U.S.C. § 1292(a), the courts of appeals can hear immediate appeals from orders granting, modifying, refusing, or dissolving injunctions, as well as orders involving receiverships and interlocutory decrees in admiralty cases.4Office of the Law Revision Counsel. 28 USC 1292 – Interlocutory Decisions No special permission is required. If a court grants or denies a preliminary injunction, either side can appeal immediately.
Certified Appeals
For interlocutory orders outside those automatic categories, a party can seek a certified appeal under 28 U.S.C. § 1292(b). This requires the trial judge to certify in writing that the order involves a controlling question of law where there’s substantial ground for disagreement and that an immediate appeal could materially advance the end of the litigation. Even then, the appellate court has discretion to accept or reject, and the application must be filed within ten days after the order is entered.4Office of the Law Revision Counsel. 28 USC 1292 – Interlocutory Decisions In practice, certified interlocutory appeals are uncommon. Most trial judges are reluctant to certify their own orders, and most appellate courts are selective about which ones they take.
The Collateral Order Doctrine
A third route runs through the collateral order doctrine, which traces back to the Supreme Court’s decision in Cohen v. Beneficial Industrial Loan Corp. This doctrine allows an immediate appeal when an interlocutory order conclusively determines a disputed question, the question is entirely separate from the merits, and the order would be effectively unreviewable after final judgment. The classic example is an order denying a claim of immunity from suit. If a government official argues they can’t be sued at all, waiting until after trial to appeal that ruling defeats the point of the immunity.
Mandamus
As a last resort, a party can petition the appellate court for a writ of mandamus under the All Writs Act, asking the higher court to order the trial judge to vacate or modify the decree.5Office of the Law Revision Counsel. 28 USC 1651 – Writs Courts grant mandamus only in extraordinary circumstances, typically when the trial court’s order represents a clear abuse of authority and no other adequate remedy exists.
Stays Pending Appeal
Filing an appeal doesn’t automatically pause the decree. Under Federal Rule of Civil Procedure 62, injunctions and receivership orders are not automatically stayed even after an appeal is filed. The injunction remains enforceable unless the court specifically orders otherwise.6Office of the Law Revision Counsel. Federal Rules of Civil Procedure Rule 62 – Stay of Proceedings to Enforce a Judgment This catches people off guard. Filing a notice of appeal doesn’t make the injunction evaporate.
To get a stay, the appealing party typically has to ask the court and may need to post a bond securing the other side’s rights. The trial court can suspend, modify, or restore the injunction on whatever terms it considers appropriate while the appeal proceeds. If the trial court refuses to grant a stay, the appellate court has the power to issue one itself.6Office of the Law Revision Counsel. Federal Rules of Civil Procedure Rule 62 – Stay of Proceedings to Enforce a Judgment The federal government is exempt from posting a bond to obtain a stay.
Enforcement and Contempt
Interlocutory decrees carry the full weight of a court order. Ignoring one is contempt of court, and courts have inherent power to enforce compliance through both civil and criminal contempt proceedings.7Federal Judicial Center. The Contempt Power of the Federal Courts Civil contempt aims to coerce compliance and can result in fines or indefinite incarceration until the person complies. Criminal contempt punishes past disobedience and carries its own penalties.
Before a court holds someone in contempt, though, the order itself must be specific enough to follow. Federal Rule of Civil Procedure 65(d) requires every injunction and restraining order to state the reasons it was issued, spell out its terms specifically, and describe in reasonable detail the acts it prohibits or requires. Vague orders that refer back to the complaint rather than spelling out what the party must do are unenforceable.1Cornell Law School. Federal Rules of Civil Procedure Rule 65 – Injunctions and Restraining Orders That specificity requirement protects people from being held in contempt for violating an order they couldn’t reasonably understand.
Enforcement can also involve law enforcement if the order requires physical actions like surrendering property or vacating a premises. An interlocutory decree, despite being temporary, demands the same respect as any other court order. Treating it as optional because the case isn’t over is one of the faster ways to end up in serious legal trouble.
