Diversity Plaintiff Sues Impleaded Party
Summit Machines sued Metro Fabrication in federal court on diversity grounds for breach of an equipment contract. Metro impleaded Apex Components under Rule 14 for contribution. Summit then added direct defect claims against Apex. The court dismissed Summit's claims against Apex because complete diversity was lacking and the statute barred supplemental jurisdiction over a plaintiff's claims against a Rule 14 party.
Late Impleader Motion Denied
Dennis hired Global Structures to build a deck that later collapsed. Global answered the complaint and more than fourteen days later filed a third-party complaint against Peak Foundation for contribution. Peak moved to strike the complaint. The court granted the motion because Global failed to obtain leave for the untimely filing even though the claim asserted derivative liability.
Independent Claim Rejected on Impleader
Ricardo Rojas sued Ridgeway Partners for construction defects. Ridgeway answered and sought to implead a supplier for direct damages Ridgeway suffered on the same project. The supplier moved to dismiss the third-party complaint. The court dismissed the claim because Rule 14 permits only derivative liability for contribution or indemnity and does not authorize an independent claim by the defendant.
Derivative Impleader Only Permitted
Riverfront Developments sued a vessel owner in federal court for cargo damage. The owner impleaded the stevedore under Rule 14(a) seeking only indemnity. The stevedore objected that the claim was too broad. The court permitted the impleader because Rule 14(a) authorizes only derivative liability for contribution or indemnity.
Arbitration Clause Blocks Impleader
Regal Apparel contracted with a supplier containing an arbitration clause. Regal was sued for defects and attempted to implead the supplier for contribution. The supplier moved to compel arbitration of the third-party claim. The court granted the motion and stayed the impleader because the contractual arbitration agreement covered the derivative claim and required enforcement.
Supplemental Jurisdiction Preserved for Defendant
BlueOcean Logistics sued Harbor Port Services on diversity grounds. Harbor impleaded Bayview Stevedoring under Rule 14 for indemnity. BlueOcean then asserted its own negligence claim against Bayview. The court dismissed only BlueOcean's claim because the statute withholds supplemental jurisdiction over plaintiff claims against Rule 14 parties in diversity actions while preserving the defendant's indemnity claim.
Common questions
Frequently Asked
4
Can a diversity plaintiff assert direct claims against a nondiverse party impleaded under Rule 14?+
No. In an action founded solely on diversity, 28 U.S.C. § 1367(b) expressly withholds supplemental jurisdiction over claims by plaintiffs against persons made parties under Rule 14, 19, 20, or 24 of the Federal Rules of Civil Procedure, or over claims by persons proposed to be joined as plaintiffs under Rule 19 of such rules, or seeking to intervene as plaintiffs under Rule 24 of such rules, when exercising supplemental jurisdiction over such claims would be inconsistent with the jurisdictional requirements of section 1332.
Does Rule 14(a) allow a defendant to implead a party for the defendant's own independent damages?
+
No. The rule authorizes impleader only when the third party may be liable to the defendant for all or part of the plaintiff's claim. It does not permit impleader for damages the defendant suffered independently from the underlying events.
Supporting sources
When must a defendant obtain leave of court to file a third-party complaint under Rule 14(a)?+
A defendant must obtain leave if the third-party complaint is filed more than fourteen days after service of the original answer. The court retains discretion to grant leave when the substantive criteria for impleader are met and no prejudice is shown.
Supporting sources
Can additional plaintiffs intervene to assert claims against a Rule 14 third-party defendant in a diversity case?+
No. Section 1367(b) bars supplemental jurisdiction over claims by persons seeking to intervene as plaintiffs under Rule 24 against a Rule 14 party when complete diversity would be destroyed. The statute applies the same prohibition to claims by would-be intervenor plaintiffs.
