NONPRECEDENTIAL O PINION*
F REEMAN , Circuit Judge. In two civil cases—District Court Nos. 23-cv-01868
(“Silverberg III”) and 2:24-cv-00924 (“Silverberg IV”)—Richard J. Silverberg asserts that
a host of parties violated more than a dozen federal and state laws. The District Court
denied some of Silverberg’s motions and dismissed both cases. For the reasons discussed

below, we will MODIFY the dismissal orders and AFFIRM them as modified. We also will
AFFIRM the other orders on appeal.
I
In his complaints for relief, Silverberg alleges a long-ranging scheme to dissuade
him from publishing a book detailing malfeasance by the City of Philadelphia (the “City”),
City officials, and numerous private entities and individuals.
A1
Silverberg’s claims relate to three groups of underlying legal matters: (1)
Silverberg’s legal representation of Mark Jackson (the “Jackson actions”), (2) the City’s
pursuit of unpaid taxes from Silverberg (the “tax cases”), and (3) Pennsylvania attorney
disciplinary proceedings against Silverberg (the “attorney disciplinary proceedings”).
The Jackson actions. Silverberg represented Jackson in a lawsuit against Rohm &
Haas Company filed in 1999 in Pennsylvania courts. When Jackson did not prevail in state
court, Silverberg represented Jackson in three federal actions against Rohm & Haas and
several other defendants. The federal actions accused the defendants of malfeasance in the
state-court litigation. Jackson did not succeed in the federal suits, but Silverberg alleges
that those suits triggered a series of fraudulent transactions between the defendants in the
current cases.
1 We recite the facts as alleged in the complaint in the light most favorable to Silverberg.
See Phillips v. Cnty. of Allegheny, 515 F.3d 224, 233 (3d Cir. 2008).

In 2016, Silverberg sent an email to defense counsel in the Jackson actions. As
relevant here, he wrote the following:
It seems like a good time to let you and others know that I will
soon be completing my book concerning the Jackson odyssey.
As I expected, this project has generated great interest since the
cases are a window into a complex and disturbing aspect of
corporate America, the conduct of corporate officials and
corporate counsel, and our broken justice system. While the
book examines the underlying conduct it also explores the
business judgment, legal and strategic decisions, individual
actions, and judicial proceedings that cumulatively led to and
killed-off multiple causes of action.
App. 74 (citation modified).2
Silverberg alleges that the Jackson defendants’ receipt of this notice about his
forthcoming book caused those parties to conspire to stop the book’s publication. To do
so, they commenced what Silverberg calls a “proxy war.” App. 17. That is, they bribed
the City to enforce a tax judgment that was entered against Silverberg in 2008.
The tax cases. In 2008, the City sued Silverberg and his law firm for unpaid taxes,
and a state court entered a default judgment against Silverberg and his firm. The City
served writs of attachment to Silverberg’s banks in 2008 and entered a suggestion of
nonpayment in 2013.
The City resumed its collection efforts in 2017, just months after Silverberg told the
Jackson defendants about his forthcoming book. Silverberg unsuccessfully moved to stop
enforcement of the judgment. Then, in 2019, the City sued Silverberg under the
2 “App.” citations refer to the appendix in Appeal No. 24-2867 (the Silverberg III appeal)
unless otherwise noted.

-- 3 of 15 --

4
Pennsylvania Uniform Fraudulent Transfer Act (“PUFTA”), alleging he fraudulently
transferred assets in 2011 to avoid paying the tax judgment. A state court entered another
default judgment against Silverberg in the PUFTA case.
Silverberg and attorneys for the City sought to negotiate a resolution to both
judgments. When those efforts failed, the City served writs of attachment against
Silverberg’s bank accounts and sought to foreclose upon a property that Silverberg owned
in Philadelphia. Silverberg contends that the City’s refusal of his settlement offers in the
tax cases shows that the City’s enforcement efforts are aimed at harassing him, not
collecting his outstanding tax liabilities.
The attorney disciplinary proceedings. In 2022, the Pennsylvania office that handles
attorney discipline (“ODC”)3 notified Silverberg that he was the subject of attorney
misconduct complaints relating to the tax cases. ODC later served Silverberg with a formal
petition for discipline, and it informed Silverberg that the complaints came from one of the
judges who presided over the tax cases (Judge Anders) and one of the City’s attorneys in
the tax cases. The attorney disciplinary proceedings were ongoing when Silverberg IV was
litigated in the District Court.
B
These appeals concern Silverberg’s third and fourth lawsuits challenging the City’s
actions related to the tax cases. Five years ago, we affirmed the dismissal of the first

Disciplinary Counsel.

lawsuit (“Silverberg I”) because the complaint violated the Rooker-Feldman doctrine.
Silverberg v. City of Philadelphia, 847 F. App’x 152, 156 (3d Cir. 2021) (non-
precedential). On the day we issued our opinion in Silverberg I, Silverberg voluntarily
dismissed his second lawsuit (“Silverberg II”).
In Silverberg III and Silverberg IV, Silverberg again challenges the City’s actions,
asserting that they were part of a vast conspiracy that he labels the “proxy war.” The
amended complaint in Silverberg III is over 100 pages long; names 24 defendants (plus 15
John Does); and asserts violations of 42 U.S.C. § 1983, RICO, and state common law.
The amended complaint in Silverberg IV incorporates the Silverberg III amended
complaint by reference. It names all the defendants in Silverberg III, plus two judges who
presided over the tax cases (Judges Anders and Roberts), ODC, and ODC’s counsel. It
essentially asserts the same causes of action as Silverberg III, but it adds allegations that
the attorney disciplinary proceedings are a continuation of the “proxy war.”
The District Court dismissed the Silverberg III amended complaint with prejudice
in a September 2024 order. In the opinion that followed, it stated that the Rooker-Feldman
doctrine precludes the exercise of subject matter jurisdiction over Silverberg’s claims. It
recognized that dismissals for lack of subject matter jurisdiction are normally without
prejudice, but it opined that Silverberg’s conduct warranted a with-prejudice dismissal. It
noted that Silverberg had filed four lawsuits,4 all seeking to reverse or nullify the state court
4 Silverberg filed Silverberg IV in March 2024, while Silverberg III was pending in the
District Court.

judgments in the tax cases, and Silverberg was not deterred by this Court’s decision in the
Silverberg I appeal. It also noted that Silverberg’s multiple injunction motions, motions
for partial summary judgment, and requests for default have caused many defendants to
expend significant resources. After dismissing the amended complaint, the District Court
issued an October 2024 order dismissing Silverberg’s extant motion for partial summary
judgment.
In Appeal No. 24-2867, Silverberg appeals the September 2024 order dismissing
the Silverberg III complaint and the October 2024 order dismissing the motion for partial
summary judgment. He also appeals an August 2023 order in which the District Court
denied his prior partial-summary-judgment motion without prejudice, deeming the motion
premature because it was filed before the defendants’ deadline to respond to the original
complaint.
The District Court dismissed the Silverberg IV amended complaint with prejudice
in a March 2025 order. In the opinion that followed, it held that (1) the Rooker-Feldman
doctrine precludes the exercise of subject matter jurisdiction over Silverberg’s claims
challenging the judgments in the tax cases, (2) judicial immunity bars the claims against
the state court judges, (3) Eleventh Amendment immunity and quasi-judicial immunity bar
the claims against the ODC Defendants, and (4) Younger abstention bars interference in
the disciplinary proceedings. The District Court also opined that dismissal with prejudice
was warranted for the reasons it stated in its Silverberg III opinion.
In Appeal No. 25-1642, Silverberg appeals the March 2025 dismissal order in
Silverberg IV.

-- 6 of 15 --

II5
With some modifications, we will affirm all orders on appeal. First, the District
Court was correct to dismiss the partial-summary-judgment motion in Silverberg III as
premature. Doe v. Abington Friends Sch., 480 F.3d 252, 257 (3d Cir. 2007) (“If discovery
is incomplete in any way material to a pending summary judgment motion, a district court
is justified in not granting the motion”).6 And the amended complaints in Silverberg III
and Silverberg IV were properly dismissed, although some claims must be dismissed
without prejudice for lack of subject matter jurisdiction.7
5 The District Court had jurisdiction under 28 U.S.C. § 1331 and § 1367. We have
jurisdiction under 28 U.S.C. § 1291. We exercise plenary review of a district court’s
dismissal orders and its application of the Rooker-Feldman and Younger abstention
doctrines. United States v. Safehouse, 146 F.4th 315, 319 (3d Cir. 2025) (dismissal orders);
Lazaridis v. Wehmer, 591 F.3d 666, 670 (3d Cir. 2010) (Rooker-Feldman and Younger
abstention). We “accept all factual allegations as true, construe the complaint in
the light most favorable to the plaintiff, and determine whether, under any reasonable
reading of the complaint, the plaintiff may be entitled to relief.” Phillips, 515 F.3d at 233
(citation modified); see also Petruska v. Gannon Univ., 462 F.3d 294, 299 n.1 (3d Cir.
2006) (noting that the same standard applies to a facial Rule 12(b)(1) dismissal or a Rule
12(b)(6) dismissal for failure to state a claim). We may affirm a district court’s judgment
on any basis supported by the record. Lazaridis, 591 F.3d at 670.
6 Additionally, the second partial-summary-judgment motion became moot when the
amended complaint was dismissed.
7 Silverberg argues that the District Court misconstrued the claims that it dismissed under
the Rooker-Feldman doctrine. See Allen v. DeBello, 861 F.3d 433, 438 (3d Cir.
2017) (recounting that the Rooker-Feldman doctrine prohibits district courts from
exercising subject matter jurisdiction if “(1) the federal plaintiff lost in state court; (2) the
plaintiff complains of injuries caused by the state-court judgments; (3) those judgments
were rendered before the federal suit was filed; and (4) the plaintiff [invites] the district
court to review and reject the state judgments.” (quoting Great W. Mining & Min. Co. v.
Fox Rothschild LLP, 615 F.3d 159, 166 (3d Cir. 2010)). He urges us to construe his claims
such that the District Court had subject matter jurisdiction. We have done so to the extent
possible. As discussed below, those claims were properly dismissed on the merits, with
prejudice.

-- 7 of 15 --

8
A
The ODC Defendants and the judges were properly dismissed, primarily on
immunity grounds.
As an arm of the Pennsylvania Supreme Court, ODC has Eleventh Amendment
immunity from suit. See Capogrosso v. Sup. Ct. of New Jersey, 588 F.3d 180, 185 (3d Cir.
2009). ODC’s employees also have Eleventh Amendment immunity from suits for
damages brought against them in their official capacities, and they have quasi-judicial
immunity from individual-capacity suits for injunctive or declaratory relief. Id.
All of Silverberg’s allegations regarding Judge Roberts and most of his allegations
regarding Judge Anders pertain to judicial actions those judges took in the tax cases. The
judges have absolute immunity from suit for those actions. See Azubuko v. Royal, 443 F.3d
302, 303–04 (3d Cir. 2006). Even assuming Judge Anders acted outside of his judicial
capacity when he lodged a complaint with ODC, Silverberg failed to state a claim against
Judge Anders for the reasons discussed below in our discussion of other defendants. See
infra Section II.C.
B
Silverberg’s allegations are too conclusory to state a claim against several
defendants.8 See Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009). He alleges, upon information
8 This conclusion applies to the following Defendants: Dupont de Nemours, Inc.; Dow,
Inc.; Corteva, Inc.; International Flavors & Fragrances; Avantor, Inc; Liberty Mutual
Group. Inc.; William Penn Foundation; Ballard Spahr LLP; Edward Breen; Rajiv Gupta;
Andreas Fibig; David H. Long; Timothy Buckley; Andrew Liveris; Janet Haas, MD; and
all John Doe defendants associated with the entities on this list.

and belief, that his email to the Jackson defendants about his forthcoming book caused
numerous individuals and their associated entities to engage in a “proxy war” against him.
He also alleges that the City’s subsequent actions in the tax cases are the fruits of the proxy
war. But he fails to allege any facts connecting a tranche of defendants with the City’s
actions in the tax cases. As a result, his allegations do not “raise a reasonable expectation
that discovery will reveal evidence of illegal agreement” involving those defendants. Bell
Atl. Corp. v. Twombly, 550 U.S. 544, 556 (2007); see also Great W. Mining & Min. Co.,
615 F.3d at 179.
C
All claims against the remaining defendants in Silverberg III and Silverberg IV were
properly dismissed for failure to state a claim or because the District Court lacked subject
matter jurisdiction under the Rooker-Feldman doctrine.9
RICO Claims. To plead a civil RICO claim, a complaint must plausibly allege at
least two predicate acts of racketeering activity. See 18 U.S.C. § 1961(1), (5). Here,
Silverberg alleges four predicate acts: (1) extortion under 18 U.S.C. § 1951, (2) witness
tampering under 18 U.S.C. § 1512, (3) obstruction of justice under 18 U.S.C. § 1503, and
9 The remaining defendants are as follows: (1) the City, its employees, and the private
parties associated with the City’s enforcement of the tax judgments (the “City
Defendants”)—i.e., the City, Gellert Scali Busenkell & Brown, LLC; Gary Seitz; James
Kenney; Marcel S. Pratt; Diana Cortes; Marrissa O’Connell; and Brian Cullin; (2) the
Vanguard Group, Inc.; (3) the ODC and its employees (the “ODC Defendants”)—i.e., the
ODC, Thomas J. Farrell, and Richard Hernandez; Judges Joshua Roberts and Daniel
Anders; and all John Doe defendants associated with the entities on this list.

-- 9 of 15 --

10
(4) mail and wire fraud under 18 U.S.C. §§ 1341 and 1343. But the facts he alleges do not
support these predicate acts.
The City Defendants’ efforts to collect the judgments in the tax cases do not
constitute extortion “under color of official right” because those money judgments were
due to the City. See 18 U.S.C. § 1951; United States v. Manzo, 636 F.3d 56, 62–65 (3d
Cir. 2011) (interpreting extortion “under color of official right” in § 1951 to require a
taking of something not due to the official ).10 And the facts do not support a violation of
the witness tampering statute because Silverberg does not allege that any defendant (1)
influenced or obstructed the presentation of witness testimony or evidence in the tax cases,
see 18 U.S.C. § 1512(b), (d); or (2) impaired any record or document in the tax cases, see
id. § 1512(c); Fischer v. United States, 603 U.S. 480, 498 (2024) (construing both 18
U.S.C. § 1512(c)(1) and (c)(2) to apply to the “impair[ment]” of “records, documents,
objects” or other items “used in [an official] proceeding”).
Obstruction of justice applies to the obstruction of federal court proceedings, not
state court proceedings like the tax cases. See 18 U.S.C. § 1503(a). And Silverberg does
not allege mail or wire fraud because a scheme to dissuade him “from moving forward with
his anticipated book,” App. 170, is not a scheme to defraud him of money or property. See
18 U.S.C. §§ 1341 and 1343; accord United States v. Pierce, 224 F.3d 158, 165 (2d Cir.
10 Any argument that the City was not entitled to collect on the judgments in the tax cases
would require this Court to review and reject the existing judgments, which is barred by
Rooker-Feldman. See Merritts v. Richards, 62 F.4th 764, 777–78 (3d Cir. 2023).

-- 10 of 15 --

11
2000) (“A scheme to deceive, however dishonest the methods employed, is not a scheme
to defraud in the absence of a property right for the scheme to interfere with.”).11
Because Silverberg’s RICO claims fail, so too does his derivative claim for RICO
conspiracy. See Lightning Lube, Inc. v. Witco Corp., 4 F.3d 1153, 1191 (3d Cir. 1993).
Constitutional Claims. Silverberg’s constitutional claims under 42 U.S.C. § 1983
also fail.
In his First Amendment claims, Silverberg alleges that the City Defendants
conspired to enforce the judgments in the tax cases with the aim of (1) deterring him from
revealing defendants’ wrongful acts in a book, and (2) retaliating against him for filing
Silverberg I and Silverberg II. But he has not alleged that the City Defendants knew of his
threat to publish a book. See Ambrose v. Twp. of Robinson, 303 F.3d 488, 493 (3d Cir.
2002) (“It is only intuitive that for protected conduct to be a substantial or motiv[at]ing
factor in a decision, the decisionmakers must be aware of the protected conduct.”). That
leaves the assertion that the City Defendants retaliated against him for filing Silverberg I
and Silverberg II. Silverberg asks us to infer retaliation from the City’s settlement offer in
the tax cases, which included a condition that Silverberg release his claims against the City
in Silverberg I and Silverberg II. But that condition is not evidence of retaliatory motive.
See Lauren W. ex rel. Jean W. v. DeFlaminis, 480 F.3d 259, 269 (3d Cir. 2007) (rejecting
11 To the extent that Silverberg alleges a fraud to deprive him of the money he owed in the
tax cases, the District Court lacked subject matter jurisdiction under the Rooker-Feldman
doctrine.

-- 11 of 15 --

12
an argument that “when parties are in a dispute and are discussing its resolution, one side,
in advancing its position is negotiating, and the other is retaliating”).
Silverberg also claims that the enforcement of the judgment in the tax cases violated
his Due Process rights. He does not specify whether this is a substantive or procedural due
process claim, but it fails under either theory. The City Defendants’ actions do not “shock
the conscience” as required for a substantive due process claim. Kane v. Barger, 902 F.3d
185, 192 (3d Cir. 2018). And Silverberg does not allege that he was denied the procedural
protections required in tax enforcement actions. See Berne Corp. v. Gov’t of the Virgin
Islands, 570 F.3d 130, 138 (3d Cir. 2009).
State Law Claims. Silverberg’s state law claims fare no better.
Silverberg’s abuse-of-process claims fail because no allegations support that the tax
cases were “so lacking in justification as to lose [their] legitimate function[s] as . . .
reasonably justifiable litigation procedure[s].” Gen. Refractories Co. v. Fireman’s Fund
Ins. Co., 337 F.3d 297, 308 (3d Cir. 2003).12 And he fails to state a common law fraud
claim because his generalized allegations do not comply with Rule 9(b)’s particularity
requirement by, for instance, specifying which statements by which defendants are
12 To the extent that Silverberg raises an abuse of process claim against his disciplinary
proceedings, Younger abstention was warranted. See Younger v. Harris, 401 U.S. 37
(1971). The Younger doctrine prohibits federal courts from enjoining state court
proceedings when: (1) the proceedings are “ongoing and judicial in nature,” (2) “implicate
important state interests,” and (3) “afford an adequate opportunity to raise federal claims.”
Borowski v. Kean Univ., 68 F.4th 844, 849 (3d Cir. 2023).

13
fraudulent or false. Fed. R. Civ. P. 9(b); Frederico v. Home Depot, 507 F.3d 188, 200–02
(3d Cir. 2007) (applying Rule 9(b) to a common law fraud claim).
The tortious interference claim cannot succeed because the City Defendants acted
with “privilege or justification” when they sought to enforce a judgment by attaching his
bank accounts and seeking to foreclose on his property. See Acumed LLC v. Advanced
Surgical Servs., Inc., 561 F.3d 199, 212–15 (3d Cir. 2009); Restatement (Second) of Torts
§ 767 cmts. b, c (A.L.I. 1979). The conversion claim fails for a similar reason: Silverberg
cannot plausibly allege that the City Defendants acted “without legal justification” when
they sought to enforce the tax judgments.13 See Universal Premium Acceptance Corp. v.
York Bank & Tr. Co., 69 F.3d 695, 704 (3d Cir. 1995) (citation modified).
Nor can the collection of duly issued tax judgments constitute intentional infliction
of emotional distress because those collection efforts were not “so outrageous in character,
and so extreme in degree, as to go beyond all possible bounds of decency, and to be
regarded as atrocious, and utterly intolerable in a civilized society.” Hoy v. Angelone, 720
A.2d 745, 754 (Pa. 1998) (citation modified).
Lastly, because the state and federal claims over which the District Court had
subject matter jurisdiction fail, his civil conspiracy claims also fail. See Boyanowski v.
Cap. Area Intermediate Unit, 215 F.3d 396, 405–06 (3d Cir. 2000).
13 To the extent that he sought to do so, the District Court lacked subject-matter jurisdiction
under the Rooker-Feldman doctrine.

-- 13 of 15 --

14
Challenges to Disciplinary Proceedings. Silverberg’s defamation claim and his
claim for intentional infliction of emotional distress with respect to the disciplinary
proceedings are barred by the Younger abstention doctrine. See Addiction Specialists, Inc.
v. Twp. of Hampton, 411 F.3d 399, 408–09 (3d Cir. 2005) (deeming a proceeding
“ongoing” for Younger abstention purposes because it was pending when the plaintiff
“filed [his] initial complaint in federal court”), abrogated on other grounds by Spring
Commc’ns, Inc. v. Jacobs, 571 U.S. 69, 72 (2013). In his appellate brief, Silverberg urges
us to apply the “bad faith” exception to Younger. But he alleges instances of bad faith that
do not appear in the Silverberg IV complaint. Because the record does not support the bad
faith exception, see Juidice v. Vail, 430 U.S. 327, 338 (1977); accord Klayman v. Porter,
104 F.4th 298, 312 (D.C. Cir. 2024), the District Court properly abstained. Dismissal with
prejudice was required. Lui v. Comm’n, Adult Ent., 369 F.3d 319, 327 (3d Cir. 2004).
III
The District Court was correct to dismiss all claims in Silverberg III and Silverberg
IV. For the most part, dismissal with prejudice was warranted. However, the dismissals
should have been without prejudice where (1) the District Court lacked subject matter
jurisdiction under the Rooker-Feldman doctrine or (2) dismissal was proper on Eleventh
Amendment immunity grounds. See Associated Builders & Contractors W. Pa. v. Cmty.
Coll. of Allegheny Cnty., 81 F.4th 279, 291 (3d Cir. 2023); Merritts, 62 F.4th at 769. Thus,

-- 14 of 15 --

15
we will modify the District Court’s dismissal orders to be without prejudice as to the claims
we have resolved on either of those grounds.14
* * *
For the above reasons, in Appeal No. 24-2867 we will AFFIRM the District Court’s
August 2023 and October 2024 orders. We also will MODIFY the District Court’s
September 2024 to be a dismissal in part with prejudice and in part without prejudice, and
we will AFFIRM that order AS MODIFIED .
In Appeal No. 25-1642, we will MODIFY the District Court’s March 2025 order to
be a dismissal in part with prejudice and in part without prejudice, and we will AFFIRM that
order AS MODIFIED .
14 All of Silverberg’s pending motions are denied.
