Foreclosure-Related Federal Claims Barred by Rooker-Feldman and New Jersey’s Entire Controversy Doctrine; Undeveloped Appellate Issues Are Forfeited

Case: Catherine Lin-Hendel v. Linton Turner, No. 25-1128 (3d Cir. Mar. 13, 2026) (not precedential)

1. Introduction

This appeal arises from long-running mortgage-foreclosure litigation involving pro se appellants Dr. Catherine G. Lin-Hendel and Dr. Rudolf H. Hendel (the “Appellants”) and a wide array of defendants, including financial institutions (notably Bank of America and Wilmington Trust), mortgage-related entities, lawyers and law firms, insurers, and judges.

The dispute traces back to two mortgage-related obligations: a 2006 $1.5 million Bank of America loan secured by a mortgage on the Appellants’ Summit, New Jersey home, and a 2006 home equity line of credit likewise secured. After transfers of interests to Wilmington Trust (as trustee for a trust), foreclosure proceedings began in New Jersey state court in 2018, leading to summary judgment against Appellants in 2019. Appellants also filed an earlier federal action in 2019 asserting, among other theories, patent infringement, fraud, and RICO claims; that case was dismissed in 2020, and the court denied leave to add new defendants.

In 2023, Appellants filed the federal action at issue here, again naming dozens of defendants and alleging fraud, RICO violations, “bad faith practices,” and broad “assault” on their property and personal rights. After motions to dismiss, the District Court dismissed the complaint with prejudice. The Third Circuit affirmed.

The key appellate issues resolved were procedural and jurisdictional: (i) which arguments were forfeited due to inadequate briefing, (ii) whether federal courts may review state-court foreclosure judgments, and (iii) whether New Jersey preclusion principles (including the entire controversy doctrine) barred repackaged fraud and chain-of-title theories that could have been raised in the foreclosure litigation.

2. Summary of the Opinion

The Third Circuit (per curiam) affirmed dismissal under Rule 12(b)(6). It held:

  • Most claims and defendant-specific challenges were forfeited because Appellants’ opening brief did not develop them.
  • To the extent Appellants sought federal review of the state foreclosure judgment, the Rooker-Feldman doctrine barred relief.
  • Appellants’ “newly uncovered” chain-of-title fraud theory—premised on events from 2006—was barred by New Jersey’s entire controversy doctrine / claim-preclusion principles because it could have been raised during the foreclosure action.
  • Broad allegations of an international, multi-entity RICO conspiracy were conclusory and failed plausibility and specificity requirements.
  • The District Court did not abuse its discretion in denying leave to amend as futile, particularly given Appellants’ prior federal action and repeated deficiencies.

The panel also noted (without dispute on appeal) that the judicial defendants were entitled to absolute judicial immunity.

3. Analysis

3.1. Precedents Cited

Pleading posture and materials considered on a Rule 12(b)(6) motion

  • Davis v. Wells Fargo, 824 F.3d 333 (3d Cir. 2016): The opinion invokes Davis for the review framework permitting consideration of “exhibits attached to the complaint, matters of public record, as well as undisputedly authentic documents” integral to the claims. This matters in mortgage/foreclosure spillover litigation, where public filings (foreclosure dockets, assignments, judgments) are commonly central to the asserted federal theories.
  • Fowler v. UPMC Shadyside, 578 F.3d 203 (3d Cir. 2009) and Warren Gen. Hosp. v. Amgen Inc., 643 F.3d 77 (3d Cir. 2011): These cases supply the Third Circuit’s standard for plenary review and the “facial plausibility” requirement when evaluating dismissal under Rule 12(b)(6).

Appellate forfeiture and limits on arguments raised on appeal

  • In re Wettach, 811 F.3d 99 (3d Cir. 2016): The panel relied on Wettach to deem forfeited issues that were not developed in the opening brief. This was decisive because Appellants discussed only a small subset of defendants and theories with any specificity, leaving most of the District Court’s rulings untouched on appeal.
  • Jenkins v. Superintendent of Laurel Highlands, 705 F.3d 80 (3d Cir. 2013) and Barna v. Bd. of Sch. Dirs. of Panther Valley Sch. Dist., 877 F.3d 136 (3d Cir. 2017): These cases reinforced two common appellate constraints: (i) arguments and factual allegations raised for the first time on appeal are generally not considered, and (ii) issues first raised in a reply brief are forfeited.

Jurisdictional bar to federal review of state-court foreclosure judgments

  • Exxon Mobil Corp. v. Saudi Basic Indus. Corp., 544 U.S. 280 (2005): The opinion uses Exxon Mobil for the modern statement of the Rooker-Feldman doctrine: federal district courts lack jurisdiction over suits by state-court losers complaining of injuries caused by state judgments and inviting federal-court review and rejection of those judgments. Applied here, any claim functionally seeking to undo or invalidate the foreclosure judgment (or its legal consequences) was barred.

New Jersey preclusion and the entire controversy doctrine

  • In re Mullarkey, 536 F.3d 215 (3d Cir. 2008): The panel cited Mullarkey for the baseline elements of claim preclusion/res judicata (final judgment on the merits; same parties or privies; subsequent suit based on the same cause of action) as applied under New Jersey and federal law.
  • Mori v. Hartz Mountain Dev. Corp., 472 A.2d 150 (N.J. Super. Ct. App. Div. 1983): The opinion relied on Mori for New Jersey’s expansive entire controversy doctrine: it reaches not only matters actually litigated, but also those that “might have been” litigated as part of the same controversy.
  • Delacruz v. Alfieri, 145 A.3d 695 (N.J. Super. Ct. Law Div. 2015): Cited to emphasize that, in foreclosure litigation, the entire controversy doctrine captures “germane” counterclaims that could have been brought in the foreclosure action. The panel used this to bar Appellants’ chain-of-title and related fraud theories premised on facts allegedly available long before the federal suit.

Plausibility and RICO pleading specificity

  • Bell Atl. Corp. v. Twombly, 550 U.S. 544 (2007): The court invoked Twombly for the requirement that a complaint include enough factual matter to make relief “plausible on its face.” This was central to rejecting vague assertions of a sweeping conspiracy across many unrelated actors.
  • Rose v. Bartle, 871 F.2d 331 (3d Cir. 1989): The opinion used Rose to underline that civil RICO conspiracy allegations must be pleaded with sufficient specificity; generalized claims of “enterprise” conduct and coordinated wrongdoing are inadequate without concrete factual detail tying defendants to actionable predicate acts and an agreement.

Leave to amend and futility

  • Grayson v. Mayview State Hosp., 293 F.3d 103 (3d Cir. 2002): The panel cited Grayson to support affirmance of dismissal with prejudice where amendment would be futile. Here, futility was bolstered by (i) incurable jurisdictional/preclusion barriers and (ii) Appellants’ history of a prior federal case where similar deficiencies were identified and not cured.

Related prior proceeding

  • Lin Hendel v. Wilmington Tr., No. CV 19-14707, 2020 WL 14008510 (D.N.J. Mar. 30, 2020): Although not “precedent” in the formal sense, the Third Circuit relied on the procedural history and reasoning of this earlier dismissal to contextualize why renewed, similar claims and new defendants did not warrant further amendments and why Appellants had already been alerted to deficiencies (including what is required to plead patent infringement).

3.2. Legal Reasoning

(a) Forfeiture narrowed the appeal

The court first narrowed the operative appellate issues via forfeiture doctrine: because the opening brief meaningfully discussed only a handful of defendants and did not engage the District Court’s rulings as to many claims, defendants, and ancillary orders, those matters were treated as forfeited. This step functionally prevented the appeal from serving as a vehicle to relitigate the entire “kitchen-sink” complaint.

(b) Rooker-Feldman blocked de facto appellate review of the foreclosure judgment

The panel treated attempts to challenge the foreclosure outcome—directly or indirectly—as jurisdictionally barred. Under Exxon Mobil Corp. v. Saudi Basic Indus. Corp., federal district courts cannot review and reject state judgments. In foreclosure-adjacent federal complaints, a common pattern is to repackage objections to the state judgment (standing to foreclose, assignment defects, fraud in loan transfers) as federal fraud or RICO injuries; the Third Circuit’s reasoning reflects skepticism of such repackaging where the relief effectively undermines the state judgment.

(c) Entire controversy doctrine barred chain-of-title “new evidence” fraud theories

The central factual contention pressed on appeal was that Appellants “recently” hired an investigator who concluded Bank of America sold the loans in 2006 and therefore lacked later ownership/transfer rights. The panel did not treat the “recent discovery” framing as saving the claim. Instead, it reasoned that because the alleged transactions occurred roughly two decades earlier, the theory could have been investigated and raised in the foreclosure action; therefore, New Jersey’s entire controversy doctrine (as explained in In re Mullarkey, Mori v. Hartz Mountain Dev. Corp., and Delacruz v. Alfieri) barred subsequent federal litigation.

The important doctrinal move is treating the chain-of-title challenge as part of the same “controversy” as the foreclosure—i.e., “germane” to whether the foreclosing parties had the right to enforce the obligation and foreclose—so it belongs in the foreclosure proceeding rather than later federal suits.

(d) Conclusory RICO conspiracy allegations failed plausibility and specificity requirements

Appellants also alleged an expansive international RICO conspiracy involving dozens of entities (including judges and “agents”), combining mortgage foreclosure with alleged patent-rights exploitation. The court rejected these allegations as conclusory, applying Bell Atl. Corp. v. Twombly’s plausibility standard and Rose v. Bartle’s requirement of specificity for civil RICO conspiracy claims. The opinion reflects a common pleading principle: large-scale conspiracy narratives require concrete factual allegations connecting each defendant to the alleged enterprise, predicate acts, and an agreement—labels and broad accusations are insufficient.

(e) Dismissal with prejudice and futility

The Third Circuit affirmed denial of leave to amend as futile under Grayson v. Mayview State Hosp. because key defects were not fixable (jurisdictional and preclusion barriers) and because Appellants had already had an opportunity to pursue related claims in their 2019 federal lawsuit without curing deficiencies.

3.3. Impact

Although designated “NOT PRECEDENTIAL” and thus non-binding under Third Circuit I.O.P. 5.7, the decision is practically instructive in three recurring contexts:

  • Foreclosure-related federal litigation: It reinforces that federal complaints seeking to unravel a state foreclosure judgment will often encounter Rooker-Feldman and, for claims that could have been asserted in foreclosure, New Jersey’s entire controversy doctrine.
  • Serial litigation and “new evidence” reframing: The opinion signals that “recent investigation” does not necessarily avoid preclusion where the underlying facts are old and could have been pursued earlier with reasonable diligence.
  • Mass-defendant conspiracy pleadings: It underscores that broad RICO accusations spanning many actors (banks, lawyers, insurers, judges) require defendant-specific factual content; otherwise, dismissal under Twombly and Rose is likely.

The forfeiture discussion also serves as a procedural warning: even potentially colorable arguments can be lost on appeal if not developed in the opening brief, especially in multi-defendant, multi-claim cases.

4. Complex Concepts Simplified

  • Rule 12(b)(6) dismissal: A case can be dismissed at the pleading stage if the complaint does not allege enough specific facts to plausibly show entitlement to relief, even if the court assumes the pleaded facts are true.
  • Rooker-Feldman doctrine: Federal trial courts generally cannot act like appellate courts reviewing state-court judgments. If the injury complained of is caused by the state judgment and the plaintiff asks the federal court to undo it, jurisdiction is lacking.
  • Res judicata / claim preclusion: Once there is a final judgment, parties (and those in privity with them) generally cannot bring another lawsuit based on the same underlying dispute.
  • New Jersey entire controversy doctrine: A particularly broad form of preclusion requiring litigants to bring all claims arising out of the same controversy in one action (including claims that could have been raised earlier). In foreclosure cases, this often includes “germane” counterclaims about the mortgage debt, assignments, or standing to foreclose.
  • Forfeiture on appeal: Appellate courts usually decide only issues actually argued with supporting reasoning in the opening brief; undeveloped issues are treated as abandoned.
  • Absolute judicial immunity: Judges are generally immune from suits for money damages for actions taken in their judicial capacity, even if a litigant alleges the actions were erroneous or improper.
  • RICO conspiracy pleading: It is not enough to allege “a conspiracy” in general terms; the complaint must include concrete facts indicating an enterprise, predicate racketeering acts, and an agreement connecting each defendant to the wrongdoing.

5. Conclusion

The Third Circuit’s disposition affirms a familiar set of gatekeeping principles in foreclosure-adjacent federal suits: (1) federal courts cannot be used to overturn state foreclosure judgments (Exxon Mobil Corp. v. Saudi Basic Indus. Corp.), (2) New Jersey’s entire controversy doctrine and claim-preclusion rules bar claims that could have been raised in foreclosure (In re Mullarkey, Mori v. Hartz Mountain Dev. Corp., Delacruz v. Alfieri), (3) expansive conspiracy narratives—especially RICO—must be pleaded with factual specificity and plausibility (Bell Atl. Corp. v. Twombly; Rose v. Bartle), and (4) appellants must clearly develop arguments in their opening brief or risk forfeiture (In re Wettach).

Even as a non-precedential opinion, the decision’s significance lies in its integrated use of jurisdictional, preclusion, and pleading doctrines to halt serial relitigation of foreclosure disputes repackaged as fraud and RICO claims, and in its emphasis that amendment may properly be denied where the core barriers are incurable and prior opportunities have already been afforded.
