Whether a federal district court has inherent or ancillary jurisdiction to enforce a settlement agreement after the underlying action has been dismissed with prejudice under Rule 41(a)(1)(ii).
Holding
No. Absent an independent basis for federal jurisdiction, a district court lacks jurisdiction to enforce a settlement agreement after dismissal unless the dismissal order incorporates the agreement or expressly retains jurisdiction to enforce it.
Reasoning
Federal courts possess only the jurisdiction granted by the Constitution and Congress. Because jurisdiction is limited and cannot be enlarged by judicial decree, the party seeking federal adjudication bears the burden of identifying a valid jurisdictional basis.
A Rule 41(a)(1)(ii) stipulation dismisses the action when filed by all appearing parties, and neither that Rule nor another cited source of law automatically gives a federal court power over later disputes concerning the settlement that led to dismissal. A claim that a party breached the settlement is a contract dispute requiring its own jurisdictional foundation.
Ancillary jurisdiction traditionally serves two related functions: allowing a single court to resolve claims that are factually interdependent, and enabling a court to manage its proceedings, vindicate its authority, and effectuate its decrees. Neither function supported jurisdiction here.
The underlying agency-agreement dispute and the later settlement-breach dispute rested on different facts. Resolving the alleged breach of the settlement was neither necessary nor particularly efficient as part of resolving the already-dismissed litigation.
Nor did enforcement of the settlement protect or effectuate the district court's dismissal order. The order required only that the lawsuit be dismissed; an alleged breach of the separate settlement agreement did not violate, flout, or imperil that order. The court's awareness and approval of the settlement terms did not make those terms part of its order.
