the Final Judgment incorporated the following from the May 28 Order:
Romspen is awarded a second priority equitable mortgage . . . based on the same terms and conditions, and securing the same total debt, as the May 16, 2013 Mortgage, Assignment of Case: 24-3255 Document: 42 Page: 4 Date Filed: 11/04/2025

Leases and Rents, Security Agreement, and Fixture filling given to Romspen by Aura Development Group, LLC. JA 144 (internal parentheticals omitted); see also JA 150-51 (incorporating findings from the May 28 Order). On October 14, 2021, Third State and Aura Investors filed a notice of appeal with the Superior Court of New Jersey, Appellate Division, seeking to challenge the Final Judgment and equitable mortgage. The Appellate Division affirmed the State Court in all respects on January 22, 2024.
Third State and Aura Investors filed a complaint in the District Court shortly after the Appellate Division affirmed the State Court. Specifically, they asserted claims under the New Jersey Quiet Title Statute, N.J. Stat. Ann. 2A:62-1, and sought a declaratory judgment to "fix the dollar amount" of Romspen's equitable mortgage (the "District Court Action"). JA 35. Romspen, for its part, filed a motion to dismiss on April 17, 2024, arguing that the District Court Action was doomed on preclusion and other grounds. Prior to a decision on its motion to dismiss, Romspen filed suit in the State Court seeking to foreclose on its equitable mortgage on Parcels G and H (the "Foreclosure Action"). Then, on November 22, 2024, the District Court granted Romspen's pending motion and dismissed the District Court Action with prejudice. Third Street and Aura Investors ("Appellants") appeal from the order dismissing their complaint.
II. JURISDICTION AND STANDARD OF REVIEW
The record before us did not clearly establish diversity jurisdiction. Under 28 U.S.C. § 1653, however, we are authorized to grant leave to amend jurisdictionally defective pleadings. To that end, on August 21, 2025, we ordered the Parties to submit supplemental Case: 24-3255 Document: 42 Page: 5 Date Filed: 11/04/2025

letter memoranda stating the basis for jurisdiction under 28 U.S.C. § 1332. On September 24, 2025, we ordered Appellants Aura Investors and Third Street to amend their complaint or submit supporting affidavits, certifications, or other proofs to substantiate or supplement their allegations of jurisdiction. They submitted a further supplemental letter explaining the basis for jurisdiction and identifying the citizenship of each of the Parties, which confirmed diversity jurisdiction. Accordingly, we proceed with subject matter jurisdiction under 28 U.S.C. § 1332(a) and appellate jurisdiction under 28 U.S.C. § 1291.
"We exercise fresh review over the District Court's dismissal of the suit under Federal Rule of Civil Procedure 12(b)(1)." Vuyanich v. Smithton Borough, 5 F.4th 379, 384 (3d Cir. 2021). Likewise, we exercise de novo review over an appeal from the District Court's grant of a motion to dismiss under Fed. R. Civ. P. 12(b)(6). Marshall v. Lauriault,
372 F.3d 175, 179 (3d Cir. 2004). We construe the complaint liberally and accept all factual allegations therein as true. In re Lipitor Antitrust Litig., 868 F.3d 231, 249 (3d Cir. 2017). "The dismissal will be upheld if we agree with the District Court that the Appellants can prove no set of facts that would entitle them to relief." Marshall, 372 F.3d at 179.
III. ISSUE PRECLUSION CONTROLS2
In relevant part, issue preclusion "bars successive litigation of an issue of fact or
7
law that was actually litigated, resolved in a valid court determination, and essential to that prior judgment, even if the issue recurs in the context of a different claim." In re Adams,
151 F.4th 144, 153 (3d Cir. 2025) (cleaned up). As we have explained, the doctrine applies when "(1) the issue sought to be precluded is the same as that involved in the prior action;
(2) that issue was actually litigated; (3) it was determined by a final and valid judgment; and (4) the determination was essential to the prior judgment." Burlington N. R. v. Hyundai Merch. Marine, 63 F.3d 1227, 1231-32 (3d Cir. 1995) (cleaned up). Each element is satisfied here.
As the District Court observed, the Parties devoted significant attention throughout the State Court Action to litigating the scope and dollar amount of Romspen's equitable mortgage. This process culminated in the Final Judgment, which incorporated an earlier finding by the State Court that Romspen held a second priority equitable mortgage "on the same terms and conditions, and securing the same total debt, as the [ADG Mortgage]." JA 144 (internal parentheticals omitted); see also JA 150-51 (incorporating findings from the May 28 Order). After the Appellate Division affirmed the Final Judgment, Appellants asked the District Court "to fix the dollar amount of Romspen's equitable mortgage and determine whether it has been [s]atisfied." JA 44-46. Thus, they seek to relitigate precisely the issue that was both litigated and determined by a final judgment in state court, and the preclusion controls, we decline to plumb the narrow depths of the Rooker-Feldman doctrine here. Laurel Gardens, LLC v. McKenna, 948 F.3d 105, 116 (3d Cir. 2020) ("[W]e may affirm on any ground supported by the record . . . .").

doctrine of issue preclusion prohibits their attempt to do so.3 Appellants dispute this outcome by asserting that the Final Judgment did not liquidate and explicitly state the face value of the equitable mortgage. And while that argument is clever, it misses the mark. Indeed, as the District Court explained in its oral decision, the exact dollar amount of the equitable mortgage was determined by the ADG Mortgage. In other words, the State Court Action ended in a determination that the current amount of the equitable mortgage may ebb and flow with the ADG Mortgage based on the terms and conditions in the ADG Loan Agreement. That the State Court did not list the precise dollar value of the ADG Mortgage—and therefore the equitable mortgage—as of the date of the Final Judgment does not mean that Appellants enjoy a second bite at the apple with respect to determining the scope and face value of the equitable mortgage.4 As ordered by incorporation into the Final Judgment, the equitable mortgage secures the same total debt as the ADG Mortgage, and the doctrine of issue preclusion bars Appellants from challenging that determination before the District Court. If they wish to liquidate the current value of the equitable mortgage, the Foreclosure Action is the appropriate venue. See, e.g., Cent. Penn Nat'l Bank v. Stonebridge Ltd., 448 A.2d 498, 504

(N.J. Super. Ct. Ch. Div. 1982) ("The purpose of a foreclosure action is to determine the right to foreclosure and the amount due on the mortgage . . . ."). * * *
We thus affirm the dismissal of Appellants' complaint.
