the Settlement Agreement among the parties dated January 7,1994.
Some 16 months later, in June 1995, plaintiff moved in the district court for a preliminary injunction to enforce the Agreement. Plaintiff did not seek to reopen his original suit, but asked for an order requiring defendants to comply with certain provisions of the Agreement. Specifically, plaintiff sought an order compelling defendants to arbitrate the merits of 19 of the claims that had previously been filed with the Department of Labor, to establish the Institute as a research institute in accordance with CUNY guidelines, to develop a faculty and staff utilization analysis and to establish a panel of experts to review and report on the adequacy of the representation of Italian-Americans at CUNY.
In September 1995, Judge Motley dismissed the motion for lack of subject matter jurisdiction. Citing Kokkonen, the judge stated:
Absent an independent basis of subject matter jurisdiction, federal courts exert continuing jurisdiction to enforce settlement agreements in two situations: (1) where the prior order of dismissal contains an express provision retaining the district court’s jurisdiction over the settlement agreement, and (2) where the order dismissing the suit specifically incorporates the terms of the settlement agreement as an operative part of the order.
Judge Motley then held that the Dismissal Order had neither included an express provision retaining jurisdiction nor explicitly incorporated the terms of the Agreement. Since there was no independent basis for jurisdiction over the Agreement, the judge denied the motion.
This appeal followed.
II. Discussion
We review de novo a determination of subject matter jurisdiction as a matter of law. In re Vogel Van & Storage, Inc., 59 F.3d 9, 11 (2d Cir.1995). Plaintiff, who is seeking to invoke the subject matter jurisdiction of the district court, bears the burden of showing that he was properly before that court. McNutt v. General Motors Acceptance Corp., 298 U.S. 178, 189, 56 S.Ct. 780, 785, 80 L.Ed. 1135 (1936); United Food & Commercial Workers Union, Local 919 v. CenterMark Properties Meriden Square, Inc., 30 F.3d 298, 301 (2d Cir.1994).
Plaintiff alleges that his motion for enforcement of the Agreement, which provided the basis for dismissal of his first federal action, comes within the jurisdiction of the district court. The principal hurdle plaintiff faces, as the district court correctly noted, is Kokkonen. In that case, the Supreme Court held that “[ejnforcement of [a] settlement agreement ... is more than just a continuation or renewal of the dismissed suit, and hence requires its own basis for jurisdiction.” — U.S. at -, 114 S.Ct. at 1675-76. In the absence of such an independent basis for jurisdiction, a federal court has jurisdiction to enforce a settlement agreement only if the dismissal order specifically reserves such authority or the order incorporates the terms of the settlement. Id. at -, 114 S.Ct. at 1677. Absent some action making a settlement agreement part of a dismissal order or some other, independent basis for jurisdiction, enforcement of a settlement agreement is for the state courts. Id.
A. Applicability of Kokkonen
Plaintiff argues that since Kokkonen was decided after the Dismissal Order, that decision does not apply here. This claim is without merit. Federal courts have regularly applied Kokkonen to stipulations and settlement agreements executed before it was decided. See, e.g., Miener v. Missouri Dep’t of Mental Health, 62 F.3d 1126, 1127 (8th Cir.1995); Hagestad v. Tragesser, 49 F.3d 1430, 1433 (9th Cir.1995); Morris v. City of Hobart, 39 F.3d 1105, 1110 (10th Cir.1994), cert. denied, — U.S.-, 115 S.Ct. 1960, 131 L.Ed.2d 852 (1995); Lucille v. City of Chicago, 31 F.3d 546, 548 (7th Cir.1994), cert. denied, — U.S. -, 115 S.Ct. 1109, 130 L.Ed.2d 1074 (1995). It is true that in none of these cases was the question of retroactivity discussed or, apparently, even raised. In each case, however, it is clear that Kokkonen was applied retroactively. The lack of discussion on the issue is explainable by each court’s knowledge of the principle that “a court is to apply the law in effect at the time
