Limitations Dismissal Preclusion Dispute
Rina Rahman sued Roger Ramirez in federal court in State X for breach of a supply contract. The court dismissed the action after applying State X's shorter statute of limitations. Rina then filed the identical claim in State Y court where the limitations period remained open. The State Y court consults its own preclusion principles to decide whether the prior federal dismissal counts as a judgment on the merits that bars the new suit.
Judgment Against One Tortfeasor
Raven Logistics and Radiance Media were both sued for the same cargo damage arising from a single shipment accident. A court entered judgment against Raven Logistics after full litigation of the negligence claim. Radiance Media later faced a separate suit by the same plaintiff for identical harm. The second court applies res judicata principles to determine the effect of the first judgment on the remaining tortfeasor.

Prior Securities Judgment Effect
Ralph Richardson brought a class action alleging misleading proxy statements in a corporate merger. An earlier SEC enforcement action against the same defendants produced a final judgment finding the statements false and misleading. Ralph moved for summary judgment in his damages suit relying on the prior determination. The court evaluates whether the earlier judgment has preclusive effect on the new suit.

Forum Non Conveniens Dismissal
Regina Robinson sued Piper Aircraft in a U.S. court for a plane crash occurring abroad. The court dismissed the action on forum non conveniens grounds after determining Scotland provided an adequate alternative forum. Regina refiled the identical wrongful death claim in state court. The new court determines whether the federal dismissal operates as a merits adjudication for claim preclusion purposes.

Patent Validity Preclusion
Ryan Roberts sued a university foundation for patent infringement. An earlier suit by the foundation against another party resulted in a final judgment invalidating the same patent. Ryan seeks to rely on that invalidity finding to defeat the infringement claim. The court assesses whether the prior judgment has preclusive effect on the new suit.
Blonder-Tongue Laboratories, Inc. v. University of Illinois Foundation402 U.S. 313, 324–25 (1971)
Class Action Preclusion Issue
Rowan Russell, a shareholder, filed a class action in federal court challenging a corporate merger. A prior state court class action involving the same merger and substantially identical claims produced a final judgment approving the settlement. Rowan argues the federal suit is not barred because the state court lacked personal jurisdiction over absent class members. The federal court applies claim preclusion principles to decide whether the state judgment binds the new class.

Common questions
Frequently Asked
3
Does a statute-of-limitations dismissal always bar a later suit on the same claim in another court?+
No. A limitations dismissal is not automatically treated as an adjudication on the merits for claim preclusion purposes. Jurisdictions differ on whether such a dismissal precludes refiling elsewhere, and federal common law in diversity cases typically incorporates the preclusion law of the rendering state.
Supporting sources
When does a judgment against one tortfeasor affect claims against others liable for the same harm?+
The effect is determined by res judicata principles. A judgment for or against one tortfeasor does not automatically bind or release others unless the judgment after trial on the merits makes the liability of one dependent on the liability of the other.
Supporting sources
Can claim preclusion bar a compulsory counterclaim that was never asserted?+
Yes. A party who fails to assert a compulsory counterclaim arising from the same transaction or occurrence forfeits that claim. Claim preclusion then prevents the party from bringing the omitted claim in a later action.
