SUMMARY ORDER

UPON DUE CONSIDERATION WHEREOF, IT IS HEREBY ORDERED, ADJUDGED, AND DECREED that the appeal is DISMISSED for lack of appellate jurisdiction.

On May 24, 2010, the City of White Plains, New York, passed an ordinance providing that certain fire fighters “shall continue to be entitled ... to have the city contribute eighty-five percent of the premium charged by the New York State Empire Health Insurance Program toward the cost of providing individual or family coverage under any of the health insurance programs the city makes available to its employees.” Joint App’x 83. About a month later, unions representing active and retired fire fighters filed suit in the Southern District of New York against the City of White Plains and various city officials, alleging nine causes of action for purported violations of their constitutional rights, breach of contract, violation of New York Civil Service Law, and relief under New York Civil Practice Law and Rules Article 78. The defendants then moved to dismiss several of the plaintiffs’ claims. As relevant here, the District Court (in an order dated September 30, 2011) granted the defendants’ motion to dismiss all claims asserted on behalf of active and recently retired fire fighters because those claims were not yet ripe for review. The active and recently retired fire fighters then appealed that order, arguing that the District Court erred in finding their claims not justiciable. We assume the parties’ familiarity with the facts and issues in this case.

On appeal, the defendants argue that we lack appellate jurisdiction and therefore must dismiss this appeal without considering the merits. We agree. As relevant here, our appellate jurisdiction is limited to review of final judgments, see 28 U.S.C. § 1291, 1 clarified by Rule 54(b) of the Federal Rules of Civil Procedure. 2 We have explained:

Rule 54(b) of the Federal Rules of Civil Procedure sets out the requirements for the entry of a partial final judgment in multi-claim or multi-party actions. A final judgment may be entered as to some — but fewer than all — claims or *680 parties only upon an express determination that there is no just reason for delay and upon an express direction for the entry of judgment.” Fed.R.Civ.P. 54(b). The Rule makes clear that if the District Court does not both direct entry of judgment and expressly determine that there is no just reason for delay, then its order or decision is not final, whether or not it is labeled a “judgment.”

HBE Leasing Corp. v. Frank, 48 F.3d 628, 631 (2d Cir. 1995). “The requirement of an express determination cannot be met if the District Court does not make clear that such determination is for the purpose of certifying a final judgment [under Rule 54(b)].” Id.

In this ease, the District Court granted the defendants’ motion to dismiss several claims, but “there is simply no evidence that the District Court intended its ruling ... to constitute a Rule 54(b) certification.” Id. Nor is the ruling a collateral order under Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541, 546-47, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). Accordingly, we must dismiss this appeal for lack of jurisdiction. Should the appellants so choose, they may file a motion in the District Court requesting the appropriate certification under Rule 54(b) and, if granted, reinitiate their appeal. Cf. In re Chateaugay Corp., 922 F.2d 86, 91-92 (2d Cir. 1990).

CONCLUSION

For the foregoing reasons, this appeal is DISMISSED for lack of appellate jurisdiction.
