Dеfendants appeal the district court’s grant of class certification in this breach-of-contract action. Because we conclude that the district court lacked diversity jurisdiction and should not have exercised supplemental jurisdiction, we vacate the district court’s class certification order and direct the district court to remand the case to the Wayne County Circuit Court.
Dale and Deborah Durant filed a class action against lawn care companies TruGreen, Inc., TruGreen Limited Partnership, and their corporate parent, The ServiceMaster Company, (collectively “TruGreen”) in Michigan state сourt on behalf of TruGreen’s customers throughout the United States. The Durants alleged breach of contract, unjust enrichment, and Michigan Consumer Protection Act сlaims based on TruGreen’s adding a one dollar fuel surcharge to each customer’s invoice. The Durants also sought to enjoin TruGreen from imposing the surcharge.
TruGreen removed the case to federal court on the basis of diversity jurisdiction, and the Durants moved to remand, claiming that the potential award due any individual plaintiff failed to satisfy the jurisdictional amount. The district court denied remand, holding that plaintiffs could meet the jurisdictional amount by aggregating their claims for punitive damages and unjust enrichment. The court certified its determinations for interlocutory appeal.
Instead of appealing, the Durants amended their complaint to add a Racketeer Influenced and Corrupt Organizations Act (“RICO”) claim, 18 U.S.C. § 1962(c), thereby creating federal question jurisdiction. The district court dismissed the RICO claim for failure to adequately plead the existence of a distinct enterprise. Plaintiffs then amended their complaint to include a claim under the Tennеssee Consumer Protection Act. Ultimately, the district court certified the class as to the breach-of-contract claim under Federal Rule of Civil Procedure 23(b)(8). We granted TruGreen leave to appeal class certification pursuant to Federal Rule of Civil Procedure 23(f).
II
Plaintiffs argue that the district court lаcked diversity jurisdiction because the amount in controversy did not exceed $75,000, and that although the RICO claim supported federal question jurisdiction, after its dismissal, the district court should not have exercised supplemental jurisdiction over their state law claims. We agree.
A. Diversity Jurisdiction
A district court may exercise diversity jurisdiction only if the amount in controversy exceeds $75,000, exclusive of interest and costs. 28 U.S.C. § 1332. The party seeking the federal forum bears the burden of proving that the amount in contrоversy exceeds $75,000. McNutt v. Gen. Motors Acceptance Corp.,
Multiple plaintiffs may aggregate their claims to meet the jurisdictional amount only if those plаintiffs “unite to enforce a single title or right in which they have a common and undivided interest.” Snyder v. Harris,
Accordingly, plaintiffs here cannot aggregate their individual claims for unjust enrichment because the plaintiff group is not seeking recovery of a single indivisi
To conclude that plaintiffs can aggregate their unjust enrichment claims, the district court relied on this court’s stаtement in Sellers v. O’Connell that “[a]n identifying characteristic of a common and undivided interest is that if one plaintiff cannot or does not collect his share, the shares of the remaining plaintiffs are increased.”
Thе district court similarly erred in concluding that plaintiffs may aggregate claims for punitive damages. Each plaintiff may claim punitive damages based on his transaction with TruGreen, and the possibility that plaintiffs might receive punitive damages from a single fund does not convert their individual claims into an indivisible res. Crawford v. F. Hoffman-La Roche Ltd.,
TruGreen also argues that the cost of complying with plaintiffs’ request for injunctive relief satisfies the jurisdictional amount because TruGreen would lose several million dollars if forced to discontinue the surcharge. We reject that argument, however, because TruGreen may not satisfy the amount-in-controversy requirement by aggregating the costs per plaintiff to comply with the injunction.

B. Supplemental Jurisdiction
Although plaintiffs’ state law claims did not satisfy the amount-in-controversy requirement for diversity jurisdiction, plaintiffs’ adding a federal RICO claim gave the district court supplemental jurisdiction over those state law claims. 28 U.S.C. § 1367(a). But the district court could — and in this case should — have declined to exercise supplemental jurisdiction after it dismissed the RICO claim, notwithstanding plaintiffs’ failure to seek remаnd after the district court dismissed the RICO claim. Id. § 1367(c)(3).
Constitutional and prudential limits on the use of federal judicial power restricted the district court’s discretion to exerсise supplemental jurisdiction. Musson Theatrical, Inc. v. Federal Express Corp.,
TruGreen argues that plaintiffs waived the right to challenge thе district court’s exercise of supplemental jurisdiction by failing to seek remand after the district court dismissed the RICO claim. Though generally failure to object in the district court waives any objection to that court’s exercise of supplemental jurisdiction, where special circumstances exist, failure to objeсt in the district court does not waive the objection on appeal.

For the foregoing reasons, we vacate the court’s order granting plaintiffs’ motion for class certification and direct the district court to remand the case to the Wayne County Circuit Court.
