*161 OPINION OF THE COURT
Having lost in state court, Great Western Mining & Mineral Company (“Great Western”) brought a civil rights action in federal court under 42 U.S.C. § 1983. Great Western alleges that its state-court losses were the result of a “corrupt conspiracy” between the named defendants and certain members of the Pennsylvania state judiciary to exchange favorable rulings for future employment as arbitrators with ADR Options, Inc. (“ADR Options”), an alternative dispute resolution entity. The District Court dismissed Great Western’s complaint for failure to state a claim and denied its motion for reconsideration and motions for leave to amend its complaint.
As a threshold matter, we address Defendants’ contention that the
Rooker-Feldman
doctrine precludes the exercise of subject matter jurisdiction over this action. We disagree, as Great Western is not “complaining of injuries caused by state-court judgments rendered before the district court proceedings commenced and inviting district court review and rejection of those judgments.”
Exxon Mobil Corp. v. Saudi Basic Indus. Corp.,
I.
This case originates out of a dispute involving a miniature golf course in which Active Entertainment, Inc. (“Active”) was the losing party. 1 Active retained Brown-stein & Vitale, P.C. (“B & V”) to represent it in litigation against an entity that Active had hired to build a miniature golf course. Dissatisfied with the damages awarded in that litigation, Active brought a malpractice suit against its counsel, Gary Brown-stein, Marc D. Vitale, and B & V. All parties agreed to binding arbitration before Thomas Rutter and Rutter’s company, ADR Options. James F. Wiley, III, represented Active; Thomas Paradise, a partner. at Fox Rothschild LLP (“Fox Rothschild”), represented Vitale.
According to the Complaint, ADR Options is the largest provider of alternative dispute resolution (“ADR”) services in Pennsylvania, New Jersey, and Delaware. Rutter is the founding shareholder and Chief Executive Officer of ADR Options. Many of ADR Options’s arbitrators are former federal and state judges.
Before beginning arbitration proceedings, the parties entered into a binding ADR Options Arbitration Agreement, which provided that:
Each party and participating attorney has disclosed any past or present relationship with the arbitrator, direct or indirect, whether financial, professional, social or any other kind. The arbitrator has also disclosed any past or present relationship with any party or attorney. It is understood that any doubt has been resolved in favor of disclosure.
(J.A. at 114 [Proposed Am. Compl. 3, ¶ 14].) The result of the arbitration pro *162 ceedings was an award for defendants Brownstein, Vitale, and B & V. Thereafter, Great Western became the assignee of Active’s interest.
Great Western filed a petition in Pennsylvania state court to vacate the arbitration award on the ground of improper failure to disclose potential conflicts. In particular, Great Western alleged that the managing partner at Fox Rothschild, Louis Fryman, was concurrently employed at ADR Options as an arbitrator and that Paradise maintained a professional relationship with Rutter. 2 The Philadelphia Court of Common Pleas and the Superior Court of Pennsylvania ruled against Great Western and confirmed the arbitration award. The Supreme Court of Pennsylvania denied Great Western’s petition for allowance of appeal.
While its appeal was pending before the Superior Court of Pennsylvania, Great Western filed a separate civil action in the Philadelphia Court of Common Pleas against Rutter, ADR Options, Fox Rothschild, and Paradise, raising contract and tort claims and alleging a failure to disclose the purportedly improper relationships. Robert Tintner, a partner at Fox Rothschild, represented all of the defendants. The Court of Common Pleas dismissed the action as collaterally estopped, and Great Western appealed. According to Great Western’s counsel, Wiley, shortly thereafter Tintner called Wiley and informed him that “[t]here [was] no way that a Philadelphia court [was] ever going to find against Thomas Rutter given his relationship with the Philadelphia court system.” (J.A. at 118 [Proposed Am. Compl. 3, ¶ 43].) The Superior Court of Pennsylvania affirmed the decision of the Court of common Pleas dismissing the action, and the Supreme Court of Pennsylvania denied Great Western’s petition for allowance of appeal.
Thereafter, Great Western filed a federal action under 42 U.S.C. § 1983, claiming deprivations of procedural and substantive due process. As defendants, Great Western named Fox Rothschild, Paradise, Tintner, ADR Options, and Rutter (collectively, “Defendants”). Great Western alleged that the Pennsylvania state-court decisions were corrupted by the improper influence of Defendants, arising both from the Pennsylvania courts’ reliance on Rutter’s services and from Pennsylvania judges’ prospect of future employment with ADR Options. Specifically, Great Western claimed that “Defendants had the power yet failed to take action to prevent violation of Great Western’s constitutional rights to due process.” (J.A. at 127 [Proposed Am. Compl. 3, ¶ 105]). The District Court granted Defendants’ motion to dismiss for failure to state a claim, holding that Great Western had not sufficiently alleged that Defendants acted under color of state law. The District Court reasoned that the corruption alleged by Great Western “exists only to the extent that defendants conspired with the courts to ensure the outcome of the underlying case” and concluded that Great Western had failed to properly allege the existence of a conspiracy between Defendants and the Pennsylvania state court system.
Great W. Mining & Mineral Co. v. Fox Rothschild LLP,
No. 08-cv-1093,
Thereafter, Great Western filed a motion for reconsideration and for leave to *163 amend its complaint pursuant to Federal Rules of Civil Procedure 59(e) and 15(a), attaching a draft amended complaint (“Proposed Amended Complaint 1”). While the reconsideration motion was pending, Great Western filed a second motion for leave to amend, seeking to substitute a new proposed draft amended complaint (“Proposed Amended Complaint 2”), which was attached. Several weeks later and without a ruling on the first two motions to amend, Great Western filed a third motion for leave to amend, seeking to substitute yet another proposed draft amended complaint (“Proposed Amended Complaint 3”), which was attached. In this motion, Great Western argued that it had newly discovered evidence, specifically Rutter’s May 14, 2009 admission under oath in another lawsuit that some of the judges who had ruled against Great Western and for ADR Options had already approached Rutter regarding the prospect of employment upon leaving the bench.
On June 24, 2009, the District Court issued an unpublished Letter Order denying the motion for reconsideration on the merits and denying the three motions for leave to amend as moot. In ruling on the motion for reconsideration, the District Court considered Proposed Amended Complaint 2, but not Proposed Amended Complaint 3. In a footnote, the District Court explained that it declined to consider Proposed Amended Complaint 3 because “[t]o allow plaintiff to repeatedly submit drafts of its complaint while plaintiffs original motions are still pending would be prejudicial to defendants.” (J.A. at 3.) The District Court denied the motion for reconsideration, holding that the allegations in Proposed Amended Complaint 2 did not support a conspiracy claim. On appeal, Great Western challenges the District Court’s refusal to consider Proposed Amended Complaint 3 and argues that the motion for reconsideration was erroneously denied.
II.
Defendants contest our jurisdiction and that of the District Court, contending that this action is barred by the
Rooker-Feldman
doctrine. Although Defendants raised this argument in their motion to dismiss, the District Court declined to address it and, exercising jurisdiction pursuant to 28 U.S.C. §§ 1331 and 1343, dismissed Great Western’s Complaint for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6). We exercise de novo review over questions of subject matter jurisdiction.

Our standard of review of a district court’s dismissal under Federal Rule of Civil Procedure 12(b)(6) is plenary.

A. Rooker-Feldman Doctrine
In certain circumstances, where a federal suit follows a state suit, the
Rook-
*164
er-Feldman
doctrine prohibits the district court from exercising jurisdiction. The doctrine takes its name from the only two cases in which the Supreme Court has applied it to defeat federal subject-matter jurisdiction:
Rooker v. Fidelity Trust Co.,
The Supreme Court characterized the lawsuit at issue in
Rooker
as an attempt “to have a judgment of a circuit court in Indiana, which was affirmed by the Supreme Court of the state, declared null and void, and to obtain other relief dependent on that outcome.”
[ujnder the legislation of Congress, no court of the United States other than this court could entertain a proceeding to reverse or modify the judgment for errors of that character. To do so would be an exercise of appellate jurisdiction. The jurisdiction possessed by the District Courts is strictly original.
Id.
at 416,
Sixty years later, the Supreme Court revisited the issue in
Feldman.
The plaintiffs in
Feldman
had petitioned the District of Columbia Court of Appeals (the equivalent of a state’s highest court,
see
28 U.S.C. § 1257(b)) for waiver of a court rule that required applicants to the District of Columbia bar to have graduated from an accredited law school.
Feldman,
Twice in
Feldman,
the Supreme Court used the term “inextricably intertwined” to describe the type of claims that plaintiffs may not raise in federal district court. First, the Court addressed the argument that if a plaintiff declined to assert certain constitutional arguments in state court, a federal district court could exercise juris
*165
diction over those claims as it would not be reviewing an issue decided by the state court.
Id.
at 482 n. 16,
[ i]f the constitutional claims presented to a United States District Court are inextricably intertwined with the state court’s denial in a judicial proceeding of a particular plaintiffs application for admission to the state bar, then the District Court is in essence being called upon to review the state court decision. This the District Court may not do.
Id. In the second instance, the Court employed the term to distinguish between the plaintiffs’ challenge to the constitutionality of the bar rules themselves, which could proceed in federal district court, and their challenge to the denial of the waiver requests, which was prohibited:
[ I]t is clear that [the plaintiffs’] allegations that the District of Columbia Court of Appeals acted arbitrarily and capriciously in denying their petitions for waiver ... required the [United States] District Court to review a final judicial decision of the highest court of a jurisdiction in a particular case. These allegations are inextricably intertwined with the District of Columbia Court of Appeals’ decisions, in judicial proceedings, to deny [the plaintiffs’] petitions. The [United States] District Court, therefore, does not have jurisdiction over these elements of the [plaintiffs’] complaints.
Id.
at 486-87,
Rooker
and
Feldman
established the principle that federal district courts lack jurisdiction over suits that are essentially appeals from state-court judgments, but they offered little instruction on how to apply that principle. Subsequent Supreme Court case law provided little further assistance. Before
Exxon Mobil,
“[t]he few decisions that have mentioned
Rooker
and
Feldman
have done so only in passing or to explain why those cases did not dictate dismissal.”
Exxon Mobil,
*166
Rejecting such an expansive application of the
Rooker-Feldman
doctrine, the Court held that it is “confined to cases of the kind from which the doctrine acquired its name: cases brought by state-court losers complaining of injuries caused by state-court judgments rendered before the district court proceedings commenced and inviting district court review and rejection of those judgments.”
Exxon Mobil,
Breaking down the holding of
Exxon Mobil,
we conclude that there are four requirements that must be met for the
Rooker-Feldman
doctrine to apply: (1) the federal plaintiff lost in state court; (2) the plaintiff “complaints] of injuries caused by [the] state-court judgments”; (3) those judgments were rendered before the federal suit was filed; and (4) the plaintiff is inviting the district court to review and reject the state judgments.
Exxon Mobil,
The second requirement — that a plaintiff must be complaining of injuries caused by a state-court judgment — may also be thought of as an inquiry into the source of the plaintiffs injury.
See Turner v. Crawford Square Apartments III, L.P.,
Suppose a state court, based purely on state law, terminates a father’s parental *167 rights and orders the state to take custody of his son. If the father sues in federal court for the return of his son on grounds that the state judgment violates his federal substantive due-process rights as a parent, he is complaining of an injury caused by the state judgment and seeking its reversal.
To the contrary, when the source of the injury is the defendant’s actions (and not the state court judgments), the federal suit is independent, even if it asks the federal court to deny a legal conclusion reached by the state court:
Suppose a plaintiff sues his employer in state court for violating both state anti-discrimination law and Title VII and loses. If the plaintiff then brings the same suit in federal court, he will be seeking a decision from the federal court that denies the state court’s conclusion that the employer is not liable, but he will not be alleging injury from the state judgment. Instead, he will be alleging injury based on the employer’s discrimination. The fact that the state court chose not to remedy the injury does not transform the subsequent federal suit on the same matter into an appeal, forbidden by Rooker-Feldman, of the state-court judgment.
Id. at 87-88 (emphasis added).
The critical task is thus to identify those federal suits that profess to complain of injury by a third party, but actually complain of injury “produced by a state-court judgment and not simply ratified, acquiesced in, or left unpunished by it.” Id. at 88. In Hoblock, after first noting that the “voters’ claims in this case seem at first to complain only of the [Board of Elections’] refusal to tally their votes rather than of any injury caused by the state court’s judgment,” the court clarified that “in refusing to tally the votes, the Board [was] acting under compulsion of a state-court order.” Id. Specifically, the Board, “had it been left to its own devices, would have counted the 40 absentee ballots,” but it was ordered not to do so by the state court. Id. at 89. Thus, “the state-court judgment produced the Board’s refusal to count the ballots, the very injury of which the voters complain.” Id.
When, however, a federal plaintiff asserts injury caused by the defendant’s actions and not by the state-court judgment,
Rooker-Feldman
is not a bar to federal jurisdiction.
See, e.g., Coles v. Granville,
Although this test is seemingly straightforward, application becomes more complicated when a federal plaintiff complains of an injury that is in some fashion related to a state-court proceeding. For example, in
McCormick v. Braverman,
In
Fieger v.
Ferry,
As is clear from the preceding discussion, the two key requirements — that the injury must be caused by the state-court judgment and that the plaintiff must invite review and rejection of that judgment— are closely related. Yet, a federal plaintiff who was injured by a state-court judgment is not invariably seeking review and rejection of that judgment. For example, in
Adkins v. Rumsfeld,
What this requirement targets is whether the plaintiffs claims will require appellate review of state-court decisions by the district court. Prohibited appellate review “consists of a review of the proceedings already conducted by the ‘lower’ tribunal to determine whether it reached its result in accordance with law.”
Bolden v. City of Topeka, Ks.,
In a case subsequent to
Exxon Mobil,
the Supreme Court again emphasized that
Rooker-Feldman
is a “narrow doctrine” that “applies only in limited circumstances.”
Lance v. Dennis,
As a final step, should the
Rooker-Feldman
doctrine not apply such that the district court has jurisdiction, “[disposition of the federal action, once the state-court adjudication is complete, would be governed by preclusion law.”
Exxon Mobil,
Turning to the instant case, the critical question is whether Great Western is a “state-court loser[ ] complaining of injuries caused by state-court judgments rendered before the district court proceedings com
*171
menced and inviting district court review and rejection of those judgments.”
Id.
at 284,
Grappling with similar claims, in two cases the Seventh Circuit has held that
Rooker-Feldman
did not operate to bar the federal proceedings. In
Nesses v. Shepard,
Nesses cannot show injury from the alleged conspiracy unless the decision dismissing his suit for breach of contract was erroneous. 5 For suppose that although there was this nefarious conspiracy his suit had no merit and so would have failed even if there had been no conspiracy. Then the conspiracy did him no harm and without harm there is no tort.... To show harm and thus keep the present suit alive, Nesses would have to show that the decision by the Indiana court in his suit for breach of contract was erroneous, and that, it may appear, Rooker-Feldman bars him from doing.
Id. at 1005 (internal citations omitted). But the Rooker-Feldman doctrine, the court concluded, “is not that broad.” Id. Nesses was not merely claiming that the decision of the state court was incorrect or that the decision itself violated his constitutional rights; such claims would be barred. Instead, because Nesses alleged that “people involved in the decision violated some independent right of his, such as the right (if it is a right) to be judged by a tribunal that is uncontaminated by politics, then he [could], without being blocked by the Rooker-Feldman doctrine, sue to vindicate that right.” Id. (emphasis added). Moreover, Nesses could, “as part of his claim for damages,” show “that the *172 violation caused the decision to be adverse to him and thus did him harm.” Id. If Rooker-Feldman barred jurisdiction, “there would be no federal remedy for a violation of federal rights whenever the violator so far succeeded in corrupting the state judicial process as to obtain a favorable judgment.” Id.
In
Brokaw v. Weaver,
We find the reasoning of the Seventh Circuit persuasive and conclude that it applies here. As in
Nesses,
Great Western, by alleging a conspiracy between Defendants and the Pennsylvania judiciary to rule in favor of Rutter and ADR Options, is attacking the state-court judgments. But, like Nesses, Great Western is not merely contending that the state-court decisions were incorrect or that they were themselves in violation of the Constitution. Instead, Great Western claims that “people involved in the decision violated some independent right,” that is, the right to an impartial forum.
Nesses,
The fact that Defendants’ actions, rather than the state-court judgments, were the source of Great Western’s injuries is alone sufficient to make Rooker-Feldman inapplicable here. Nevertheless, it is worthwhile to discuss the other key requirement — whether Great Western seeks review and rejection of the state-court judgments.
Regardless of the merits of the state-court decisions, if Great Western could prove the existence of a conspiracy to reach a predetermined outcome in state court, it could recover nominal damages for this due process violation.
Carey,
Ordinarily, having concluded our jurisdictional inquiry, the next step would be to apply state law to determine the preclusive effect of the prior state-court judgments. Defendants did not raise the issues of res judicata or collateral estoppel in their motion to dismiss or before this Court. Estoppel, as an affirmative defense, may be raised in an answer and is not waived through failure to include it in a motion to dismiss.
See
Fed. R.Civ.P. 8(c), 12(h). Preclusion, however, is not jurisdictional.
Exxon Mobil,
*174 B. Motion for Leave to Amend
As we have discussed, after the District Court granted Defendants’ motion to dismiss, Great Western filed a motion for reconsideration and a motion for leave to amend, attaching a draft amended complaint, Proposed Amended Complaint 1. While the motion for reconsideration was pending, Great Western filed two additional motions for leave to amend, each time attaching a new draft amended complaint — Proposed Amended Complaint 2, then Proposed Amended Complaint 3. In ruling on the motion for reconsideration, the District Court considered Proposed Amended Complaint 2, but not Proposed Amended Complaint 3. In a footnote, the District Court explained that “[t]o allow plaintiff to repeatedly submit drafts of its complaint while plaintiff’s original motions are still pending would be prejudicial to defendants.” (J.A. at 3.) Great Western challenges this ruling by the District Court.
Amendments to pleadings are governed by Federal Rule of Civil Procedure 15(a), which provides that “a party may amend its pleading only with the opposing party’s written consent or the court’s leave. The court should freely give leave when justice so requires.” Interpreting Rule 15(a), the Supreme Court has held:
In the absence of any apparent or declared reason — such as undue delay, bad faith or dilatory motive on the part of the movant, repeated failure to cure deficiencies by amendments previously allowed, undue prejudice to the opposing party by virtue of allowance of the amendment, futility of amendment, etc. — the leave sought should, as the rules require, be “freely given.” Of course, the grant or denial of an opportunity to amend is within the discretion of the District Court, but outright refusal to grant the leave without any justifying reason appearing for the denial is not an exercise of discretion; it is merely abuse of that discretion and inconsistent with the spirit of the Federal Rules.
Foman v. Davis,
The District Court concluded that allowing Great Western to submit a third proposed amended complaint would be prejudicial to defendants and denied leave to amend on this ground. We agree with Great Western that the District Court’s conclusion regarding prejudice was erroneous.
7
Nevertheless, we will affirm the Dis
*175
trict Court on the ground that granting leave to amend would have been futile.
See United States v. Sanchez,
Under Rule 15(a), futility of amendment is a sufficient basis to deny leave to amend. Futility “means that the complaint, as amended, would fail to state a claim upon which relief could be granted.”
In re Merck & Co. Sec., Derivative, & ERISA Litig.,
To determine whether the substitution of Proposed Amended Complaint 3 would have been futile, we consider the merits of Great Western’s motion for reconsideration and the additional allegation contained in that version of the complaint. Specifically, we question whether the addition of the new allegation is sufficient to state a claim under 42 U.S.C. § 1983 such that the District Court should have granted Great Western’s motion for reconsideration.
To prevail on a § 1983 claim, a plaintiff must allege that the defendant acted under color of state law, in other
*176
words, that there was state action.
Lugar v. Edmondson Oil Co.,
In two recent landmark cases, the Supreme Court reexamined Federal Rule of Civil Procedure 8 and the pleading standards that a plaintiff must meet to state a claim that will survive a motion to dismiss under Rule 12(b)(6). The first of these two cases,
Bell Atlantic Corp. v. Twombly,
focused on “the proper standard for pleading [a Sherman Act] antitrust conspiracy through allegations of parallel conduct.”
In
Twombly,
however, the Supreme Court announced “two new concepts.”
Phillips,
Applying these general standards to the task of pleading an antitrust conspiracy, the Court explained that:
[ A]n allegation of parallel conduct and a bare assertion of conspiracy will not suffice. Without more, parallel conduct does not suggest conspiracy, and a conclusory allegation of agreement at some unidentified point does not supply facts adequate to show illegality. Hence, when allegations of parallel conduct are *177 set out in order to make a § 1 claim, they must be placed in a context that raises a suggestion of a preceding agreement, not merely parallel conduct that could just as well be independent action.
Id.
at 556-57,
The second case,
Ashcroft v.
Iqbal, concerned allegations of discrimination on the basis of race, religion, or national origin in the wake of the September 11, 2001 terrorist attacks. — U.S. —,
[A] court considering a motion to dismiss can choose to begin by identifying pleadings that, because they are no more than conclusions, are not entitled to the assumption of truth.... When there are well-pleaded factual allegations, a court should assume their veracity and then determine whether they plausibly give rise to an entitlement to relief.
Id. at 1950. With respect to conclusory allegations, the Court clarified that “we do not reject these bald allegations on the ground that they are unrealistic or nonsensical .... It is the conclusory nature of [such] allegations, rather than their extravagantly fanciful nature, that disentitles them to the presumption of truth.” Id. at 1951.
In light of
Twombly,
“it is no longer sufficient to allege mere elements of a cause of action; instead ‘a complaint must allege facts suggestive of [the proscribed] conduct.’ ”
Phillips,
*178
We have held that to properly plead an unconstitutional conspiracy, a plaintiff must assert facts from which a conspiratorial agreement can be inferred.
D.R. v. Middle Bucks Area Vocational Tech. Sch.,
Under
Iqbal,
to assess the sufficiency of Proposed Amended Complaint 3, we “begin by identifying pleadings that, because they are no more than conclusions, are not entitled to the assumption of truth.”
The Supreme Court has held that “merely resorting to the courts and being on the winning side of a lawsuit does not make [the winning] party a co-conspirator or a joint actor with the judge.”
Dennis,
Applying Twombly, Great Western’s statement that “Defendants engaged in a concerted action of a kind not likely to occur in the absence of agreement” is inadequate to properly plead an agreement. (J.A. at 120 [Proposed Am. Compl. 3, ¶ 55].) The factual allegations of agreement on which Great Western rests its claim are as follows: (1) according to Wiley, on or about March 1, 2006, Tintner stated that there was “no way that a Philadelphia court is ever going to find against Thomas Rutter given his relationship with the Philadelphia court system” (id. at 118 [Proposed Am. Compl. 3, ¶ 43]); (2) ADR Options is the largest provider of ADR services in Pennsylvania, has a large roster of former judges employed as arbitrators, and pays its arbitrators handsomely; and (3) in May 2009, Rutter testified at a deposition that some of the judges who had ruled for ADR Options and against Great Western had already approached him about employment after they leave the bench. Great Western alleges that these factual allegations, when viewed in concert with the decisions rendered by the Pennsylvania state courts, evidence “unnatural parallelism” and a quid pro quo relationship. (Great Western Br. 18, 20.)
At most, Great Western has alleged that Pennsylvania state-court judges hoped to secure employment with ADR Options after leaving the bench and thus had an incentive to rule in the company’s favor. Fatal to its claim, however, Great Western failed to make any factual contentions concerning conduct by Rutter or any of the other Defendants. Specifically, even Proposed Amended Complaint 3 is devoid of allegations that Rutter or any of the Defendants did or said something to *179 the judges to create an understanding that favorable rulings could result in future employment. Instead, the allegations in the complaint, even when viewed in the light most favorable to Great Western, describe unilateral action on the part of certain judges. For a judge to approach a party for whom he or she has just ruled to discuss the possibility of working for that party certainly creates a strong appearance of impropriety. Yet this allegation, without a complementary allegation of conduct by the non-judicial actor, does not plausibly suggest the existence of a conspiracy between the party and the judge to exchange favorable rulings for future employment.
A comparison between the allegations in this case and those in
Dennis,
which the Supreme Court held were sufficient to survive a motion to dismiss, further emphasizes the deficiencies in Great Western’s complaint. In
Dennis,
a state court enjoined the plaintiffs from producing minerals from certain oil leases.
Furthermore, Great Western has not pleaded any facts that plausibly suggest a meeting of the minds between Rutter and members of the Pennsylvania judiciary.
See Twombly,
Great Western’s Proposed Amended Complaint 3 lacks sufficient factual allegations to create “plausible grounds to infer an agreement,” as is required by
Twombly,
*180 IV.
For the foregoing reasons, we hold that the District Court properly exercised jurisdiction. We will affirm the District Court’s denial of Great Western’s motion for leave to amend and its motion for reconsideration.
Notes
. These facts are taken from the allegations made in the Complaint, which, on a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6), the court must accept as true and view in the light most favorable to the plaintiff.
Umland v. PLANCO Fin. Servs.,
. In its federal Complaint, Great Western further alleged that Vitale was an attorney for ADR Options and Rutter. (J.A. at 124 [Proposed Am. Compl. 3, ¶ 82].) Great Western acknowledged, however, that it did not discover this information until after the state-court litigation. (Great Western Br. 7.) As such, this allegation was not included in Great Western's petition to vacate the arbitration award.
. To the extent that we have subject matter jurisdiction, we exercise it under 28 U.S.C. § 1291.
. Defendants cite to cases in which, post-
Exxon Mobil,
we relied on our
pre-Exxon Mobil
formulation of the
Rooker-Feldman
doctrine, specifically the "inextricably intertwined” test. Although we cited our pre
Exxon Mobil
definition of "inextricably intertwined,” at bottom, the holdings in these cases rested on the same concerns at issue in
Exxon Mobil
— whether the plaintiff’s claim complains of an injury caused by a state-court judgment rendered before the federal proceeding and seeks review and rejection of that judgment. Specifically, in
Taliaferro v. Darby Township Zoning Board,
In two other cases, we held that the
Rooker-Feldman
doctrine barred the suit because a favorable decision in federal court would require negating or reversing the state-court decision.
In re Madera,
Accordingly, all three of these cases are consistent with
Exxon Mobil
and with the approach we adopt today. Nevertheless, for the sake of clarity, we should exercise "caution ... in relying on our pr
e-Exxon
formulation of the
Rooker-Feldman
doctrine,” particularly those cases which may be read to suggest that the phrase "inextricably intertwined” created an additional legal test.
Gary,
. Note that even if the state-court decision was justified, a plaintiff could nevertheless be entitled to some relief based on the violation of his or her due process rights, which is an independent injury.
See Carey v. Piphus,
. In holding that the
Rooker-Feldman
doctrine did not apply, both
Brokaw
and
Ernst
also relied on an alternative ground — that the plaintiff did not have an opportunity to present the current constitutional claims in state court.
Brokaw,
. Although Defendants opposed Great Western’s motions for leave to amend before the District Court, they did not argue that granting leave to amend would prejudice them. Similarly, they do not make that argument in their brief on appeal. They contend before us, as they asserted in the District Court, that granting leave to amend would be futile as all versions of Great Western's complaint failed to state a claim on which relief could be granted. In denying leave to amend on the ground of prejudice, the District Court did not articulate specifically how permitting amendment would prejudice Defendants. See Cure *175 ton v. Nat’l Collegiate Athletic Ass’n, 252 F.3d 267, 276 (3d Cir.2001) (”[T]he obligation of the district court ... is to articulate the prejudice caused by the [amendment] and to balance those concerns against the reasons for [the amendment].”).
Nothing in the facts of this case demonstrates any particular prejudice that would have resulted from allowing Great Western to substitute Proposed Amended Complaint 3, as long as the District Court had given Defendants an opportunity to respond. We recognize that the District Court’s conclusion that permitting Great Western to repeatedly amend its complaint would prejudice Defendants is entitled to substantial deference. Nevertheless, in light of the record and the absence of a reasoned explanation of how Defendants would be prejudiced by the amendment, we conclude that the District Court erred when it denied Great Western’s third motion for leave to amend on grounds of prejudice.
. In the Order denying Great Western’s motion for reconsideration, the District Court evaluated whether allowing Great Western to substitute Proposed Amended Complaint 2 would be futile. The District Court did not assess futility with respect to Proposed Amended Complaint 3, instead declining to consider that version on the ground that it would be prejudicial to Defendants. As we have noted, the refusal to consider Proposed Amended Complaint 3 on the basis of prejudice to Defendants was an abuse of discretion. We see no reason for remand, however, because for the reasons stated in our opinion, it is clear that substituting Proposed Amended Complaint 3 would be futile.
. Great Western also appeals the denial of its motion for reconsideration, arguing that reconsideration was warranted based on previously unavailable evidence — Rutter’s statement at the May 14, 2009 deposition — and the need to correct clear errors of law. Having *180 thoroughly considered all of Great Western's arguments in favor of reconsideration, we conclude that they are without merit.
