Case Summary

Disposition

Dismissed

The First Circuit dismissed Air-Con, Inc.’s appeal for lack of appellate jurisdiction. It held that because Daikin voluntarily dismissed its counterclaim without prejudice, the district court’s order was not a final decision under 28 U.S.C. § 1291, leaving no basis for an immediate appeal.

Legal Issue

Whether a party’s voluntary dismissal of its remaining claim without prejudice creates a final, appealable judgment under 28 U.S.C. § 1291.

Circuit Positions

Circuit 0Circuit 1(this circuit)Circuit 2Circuit 3Circuit 4Circuit 5Circuit 6Circuit 7Circuit 8Circuit 10

Voluntary dismissal without prejudice defeats finality; no appellate jurisdiction under §1291.

Circuit 11

Voluntary dismissal without prejudice creates finality regardless of party intent.

Circuit 9

Finality depends on whether the dismissal was intended to manipulate jurisdiction; may allow appeal in absence of bad faith.

Conflict Summary

Most circuits hold that a voluntary dismissal without prejudice does NOT create finality because the claim can be revived in the same district court, whereas the Eleventh Circuit (and some Ninth Circuit panels) treat such dismissals as producing a final decision. The First Circuit joins the majority rule rejecting finality; the Ninth Circuit applies a case-specific manipulation test.
