Caterpillar Inc. v. Lewis
When a case is improperly removed from state court to federal court due to a lack of complete diversity, but the jurisdictional defect is cured before final judgment is entered, must the federal court's final judgment be vacated and the case sent back to state court?

The Supreme Court reversed the Sixth Circuit in a unanimous 9–0 decision authored by Justice Ruth Bader Ginsburg. The Court held that while the original removal was indeed improper and the district court had erred in denying Lewis's motion to remand, the final judgment did not need to be vacated because the jurisdictional defect had been cured before the district court entered final judgment.
Justice Ginsburg's opinion began by clearly acknowledging that the district court made a mistake. At the time Caterpillar removed the case, complete diversity did not exist—the Kentucky citizen defendants destroyed it—and the district court should have granted Lewis's motion to remand the case to state court. The Court emphasized that it was not excusing or approving of the district court's error. The removal statutes are meant to be strictly construed, and a timely motion to remand on jurisdictional grounds should have been granted.
However, the Court then turned to the practical question of what remedy was appropriate given the unusual posture of the case. By the time the case reached trial and final judgment, the nondiverse defendants had been dismissed, and only Lewis and Caterpillar remained. At that point, the federal court unquestionably had diversity jurisdiction over the remaining parties. The Court reasoned that requiring the parties to go back to state court and relitigate an identical case between identical parties would impose enormous costs on the parties and the courts without advancing any substantive interest. The wasted resources of a full federal trial could not be recovered.
The Court balanced the plaintiff's legitimate interest in choosing a forum against the systemic interests in finality and judicial efficiency. It concluded that once the jurisdictional defect was cured—here, through the dismissal of the nondiverse defendants before final judgment—the interests of finality and economy outweighed the need to vacate the judgment. The Court was careful to note, however, that this holding was limited: it applied specifically to situations where the defect was fully cured before the entry of final judgment. The ruling did not give defendants a green light to improperly remove cases with impunity, and it did not eliminate the district court's obligation to remand improperly removed cases promptly.
Concurring Opinions
The decision was unanimous with no separate concurring or dissenting opinions. All nine justices joined Justice Ginsburg's opinion for the Court.
Background & Facts
Larry Lewis was a worker at a Caterpillar Inc. facility in Kentucky. After a dispute arose over what Lewis claimed was Caterpillar's breach of a settlement agreement related to his employment, Lewis filed a lawsuit in Kentucky state court in 1994. He sued not only Caterpillar—a corporation incorporated in Delaware with its principal place of business in Illinois—but also several individual Caterpillar managers and supervisors who, like Lewis himself, were citizens of Kentucky. This detail about shared Kentucky citizenship would become the crux of the legal battle that followed.
Caterpillar wanted the case heard in federal court rather than Kentucky state court. The company removed the case, arguing first that Lewis's state-law claims were actually preempted by federal labor law (the Labor Management Relations Act), giving the federal court 'federal question' jurisdiction. Caterpillar also argued, in the alternative, that the federal court had jurisdiction based on 'diversity of citizenship'—the principle that federal courts can hear cases between citizens of different states when the amount in controversy exceeds a threshold. Lewis promptly asked the federal district court to send the case back to state court, pointing out that complete diversity did not exist because both he and the individual manager defendants were all Kentucky citizens. For diversity jurisdiction to work, no plaintiff can share state citizenship with any defendant.
The district court rejected Caterpillar's federal-question argument, finding no federal labor law preemption. However, the court then erroneously denied Lewis's motion to remand the case to state court, concluding that diversity jurisdiction existed—despite the fact that the nondiverse Kentucky defendants were still in the case. The litigation continued in federal court. Eventually, before the case went to trial, the individual Kentucky defendants were dismissed from the lawsuit through a combination of settlements and court rulings. By the time the case was tried before a jury, only Lewis (a Kentucky citizen) and Caterpillar (a Delaware/Illinois citizen) remained, meaning complete diversity now existed. The jury returned a verdict in Caterpillar's favor.
Lewis appealed to the United States Court of Appeals for the Sixth Circuit. The Sixth Circuit agreed with Lewis that the original removal had been improper—complete diversity was absent at the time of removal—and it vacated the district court's judgment entirely, ordering the case remanded to Kentucky state court. Caterpillar then petitioned the Supreme Court, which agreed to hear the case to resolve an important question about how federal courts should handle jurisdictional defects in removal that are cured during the course of litigation.
The Arguments
Caterpillar argued that even though removal was technically improper at the outset because complete diversity did not exist, the jurisdictional defect was fully cured before trial and final judgment when the nondiverse defendants were dismissed. Vacating a final judgment after a full trial and sending the parties back to state court to start over would be an enormous waste of judicial and private resources.
- By the time of trial and final judgment, only diverse parties remained in the case, meaning the federal court indisputably had subject matter jurisdiction at that point.
- Requiring the case to be retried from scratch in state court—between the same two diverse parties, on the same claims—would serve no meaningful purpose and would waste years of litigation effort.
- The interests of finality and judicial efficiency strongly favored preserving the judgment rather than unwinding a completed trial over a since-cured procedural defect.
Lewis argued that removal jurisdiction must be judged at the time of removal, and because complete diversity did not exist when Caterpillar removed the case, the federal court never properly acquired jurisdiction. The district court's refusal to remand was a clear error that stripped Lewis of his right to have the case heard in his chosen state court forum.
- Under the federal removal statute, a district court must remand a case to state court if it determines at any time that it lacks subject matter jurisdiction, and the court clearly lacked jurisdiction here at the time of removal.
- A plaintiff's right to choose a state court forum is a significant procedural right that should not be overridden simply because the defendant's improper removal eventually became less objectionable over time.
- Allowing a party to benefit from an improper removal by waiting until nondiverse defendants are dismissed would incentivize gamesmanship and undermine the integrity of the removal process.
