Definition
An interlocutory judgment is a court ruling that resolves a discrete issue, procedural step, or preliminary matter arising during the course of litigation, but does not finally dispose of the case. It leaves something further to be done before the rights of the parties are fully determined and the case is put out of court.
The concept operates in contrast to a final judgment, which conclusively settles all claims and terminates the action as to all parties. An interlocutory judgment may be entirely procedural — determining, for example, whether a defective pleading requires the defendant to answer over — or it may resolve a substantive sub-issue that feeds into the eventual final resolution. In either case, the defining characteristic is incompleteness: something remains.
In modern practice, the term appears most often not in the context of "interlocutory judgments" as a standalone procedural device, but in the phrase interlocutory appeal — the mechanism by which a party challenges a non-final ruling before the case concludes.
Common Confusion
INTERLOCUTORY JUDGMENT vs. INTERLOCUTORY ORDER vs. FINAL JUDGMENT
These three terms are frequently conflated, and the distinction matters enormously for appellate jurisdiction. A final judgment is the ruling that ends the litigation and from which an appeal as of right ordinarily lies. An interlocutory order is any non-final directive of the court — a discovery ruling, an injunction, a scheduling order. An interlocutory judgment occupies a middle space: it has the formal character of a judgment (it resolves a defined legal question with some binding effect) but it does not end the case. In many modern jurisdictions, the distinction between "interlocutory judgment" and "interlocutory order" has softened in practice, and courts often use the terms interchangeably. Researchers must not assume historical usage maps cleanly onto modern appellate finality doctrine.
Core Elements
An interlocutory judgment is characterized by three features:
1. Issued during the pendency of the action. The judgment arises in the course of litigation, not at its conclusion.
2. Resolves a preliminary, subordinate, or intermediate question. It settles a discrete procedural or substantive issue — a plea in abatement, a default on a threshold matter, an interim award of damages in a bifurcated proceeding — without reaching the ultimate merits of the entire dispute.
3. Leaves further proceedings required. Some step, determination, or adjudication remains before the case is finally resolved and closed.
Why It Matters in Research
The single most important research implication of interlocutory judgments is the finality rule and its exceptions. Under the federal system, 28 U.S.C. § 1291 limits appellate review to "final decisions." Interlocutory judgments, by definition, are not final decisions, so the default rule bars immediate appeal. This makes the statutory and equitable exceptions to finality — codified in 28 U.S.C. § 1292(a) and (b) — critical to understanding when an interlocutory ruling can be challenged before the case ends. Researchers working in appellate procedure must navigate this architecture carefully.
Historical sources use "interlocutory judgment" in a more formalized and narrower sense than modern practice does. Burrill, for instance, describes the judgment on a plea in abatement directing the defendant to "respondeat ouster" — answer over — as a paradigmatic interlocutory judgment. This was a specific procedural event in common law pleading. Modern practice has largely abandoned formal pleading stages of this kind, so researchers encountering "interlocutory judgment" in historical case law or treatises should reconstruct the procedural context rather than assume modern equivalence.
Jurisdictional variation is significant. State courts do not uniformly adopt the federal finality framework. Some states permit interlocutory appeals by right in categories that federal courts treat as discretionary (e.g., certain family law orders, injunctions, orders affecting property rights). Others are more restrictive. Researchers working in state court materials should not import federal finality doctrine without checking the applicable state appellate rules.
A further trap: in equity practice, the term "interlocutory" was used to describe decrees issued before final decree, and "interlocutory injunction" (now more often called a preliminary injunction) was a standard form of relief. Researchers in pre-merger (pre-1938 Federal Rules) materials will encounter "interlocutory decree" as the equity-side counterpart to "interlocutory judgment" at law. These are functionally similar concepts but arose from distinct procedural traditions.
In family law, interlocutory judgments appear in a specific and sometimes counterintuitive way. Several states issue an interlocutory judgment of divorce — a ruling that grants the divorce conditionally, with finality delayed for a statutory waiting period. This usage is substantive, not merely procedural, and should not be confused with the general doctrine of interlocutory rulings.
Historical Dictionary Support
Black's definition is the most complete and remains useful: an interlocutory judgment "determines some preliminary or subordinate point or plea, or settles some step, question, or default arising in the progress of the cause, but does not adjudicate the ultimate rights of the parties, or finally put the case out of court." This framing captures the essential character and is consistent across editions, though Black's does not fully account for how interlocutory appeals doctrine has expanded the significance of such rulings in modern practice.
Burrill's entry is historically instructive precisely because it is concrete. The example of a judgment on a plea in abatement — ordering the defendant to "respondeat ouster" — illustrates how interlocutory judgments functioned in the formal common law pleading system. Burrill's emphasis on the judgment being "only intermediate" and not finally completing the suit aligns with Black's, but his examples are drawn from a procedural world that the Federal Rules effectively abolished.
Rapalje and Lawrence cross-reference to their general entry on judgment, which is a notable choice. It signals that the compilers did not treat "interlocutory judgment" as a term of art requiring independent treatment — reflecting the view, consistent with the historical period, that interlocutory was simply a modifier describing temporal position in litigation, not a distinct legal category with its own doctrine.
None of the historical dictionaries engage with what has become the most practically important dimension of the term: the interlocutory appeal and its exceptions. That body of doctrine developed largely through twentieth-century statutory and case law, and researchers should not expect historical dictionary sources to illuminate it.
Jurisdictional Note
Federal appellate jurisdiction over interlocutory rulings is governed by 28 U.S.C. § 1292, which creates specific exceptions to the finality rule for injunctions, certain receivership orders, and certified questions of controlling law. State appellate rules vary considerably — some states permit interlocutory review by right in categories that federal courts treat as discretionary, and at least a handful of states (historically California among them) have used "interlocutory judgment of divorce" as a substantive procedural stage, not merely a descriptive label.
