OPINION
Aрpellants in this case, all plaintiffs below, are Sue Spera, James Surowka, Joan Tully, William Tully, Matthew Uto, Harry White, Richard Wood, Nelson Eppert, Helen Groves, Erwin Irmscher, James Keily, Ann Keily, Joseph Langley, and Richard Shore (collectively, the “Spera Plaintiffs” or “Appellants”). Appellees, all defendants below, are individual attorneys George M. Fleming, Mark Hovenkamp, John L. Grayson, and the law firm which bears their names, Fleming, Hovenkamp & Grayson, P.C. (collectively, “FH & G” or “Appellees”). In the trial court, the Spera Plaintiffs complained that FH & G breached its fiduciary duty and otherwise committed legal malpractice by seeking excessive attorneys’ fees and by failing to timely disclose a conflict of interest between the firm and its clients. In nine points of error, Appellants argue that the trial court erred in granting FH & G’s motion for summary judgment. For the reasons set out below, we affirm, in part, and reverse and remand, in part.
Background
This case stems from the tide of polybu-tylene pipe litigation which flooded the nation’s courtrooms during the last decade. Although thousands of polybutylene cases were filed in Texas, these cases were not certified as a class action. Instead, each was prosecuted on an individual basis. For ease of administration, the judge presiding over the 334th Judicial District Court was appointed to coordinate all pretrial matters in the multitude of polybutyl-ene cases pending in Harris County.
In individual lawsuits filed in Harris County against the manufacturers of poly-butylene, FH & G represented the Spera Plaintiffs and over thirty thousand other *867 parties who had suffered property damage as a result of plumbing systems made from defective polybutylene pipes. In so doing, FH & G executed contingency fee agreements with each of its clients, including the Speras. Under the terms of these agreements, each polybutylene plaintiff agreed that FH & G was entitled to an award of attorneys’ fees in the amount of 40% of all sums recovered by judgment or settlement and up to 45% of the sums recovered in the event of an appeal.
In December of 1995, an aggregate settlement was reached with two of the poly-butylene manufacturers. The settlement called for cash payments totaling $170 million, as well as provisions for replacing the plumbing in each plaintiffs’ property. Significantly, in March of 1996, after the settlement was finalized, the 334th District Court, sua sponte, ordered a series of “fairness hearings” to determine whether the attorneys’ fees and expenses proposed by FH & G under the contingent fee contracts were reasonable. Those hearings were completed in October of 1996. During the hearings, the court heard evidence from FH & G that polybutylene litigation was its dominant activity for nine years, involving the work of eight attorneys, five legal assistants, a number of contract attorneys, investigators, law clerks, and other suрport personnel. FH & G presented additional evidence that, during the course of the polybutylene litigation, the law firm conducted more than 8,000 depositions and inspected over 30,000 property units. The court also heard evidence that contingency fee percentages for complex, mass tort litigation typically range from 10% to 50%, depending upon the circumstances of each case. This evidence included the fact that the lawyers representing a nationwide po-lybutylene class action, which the FH & G clients had not joined, received attorneys fees of only around 9% of the total settlement fund.
On November 18, 1996, the 334th District Court entered an order reducing the amount of allowable attorneys’ fees by more than half of the amount provided for by the contingency fee contracts. Based on this order, the fees were reduced from 40% of the whole settlement value, to 20% of the cash settlement amount. Under the contingency fee contracts, FH & G would have received approximately $87 million in attorneys’ fees. The amount of attorneys’ fees that the court approved in place of the contractual amount was just over $33 million. The court further declined to award the $20 million in reimbursements sought by FH & G, awarding only $10 million in out-of-pocket expenses.
FH & G immediately appealed the court’s order regarding the attorneys’ fees, and that case was assigned to the First Court of Appeals. 1 In a December 1996 newsletter distributed to its polybutylene clients, FH & G informed the clients of its intent to appeal the 334th District Court’s decision. FH & G also acknowledged, for the first time, that the attorneys’ fees issue raised by the court — more than eight months earlier in March of 1996 — posed a “conflict of interest” between the law firm and the clients. In July of 1997, FH & G sent additional written correspondence to its polybutylene clients offering to settle the attorneys’ fee dispute. From July of 1997, through September of 1998, over 20,-000 of the polybutylene clients represented by FH & G resolved their claims over the disputed attorneys’ fees. However, none of the Spera Plaintiffs entered into a settlement with FH & G over the disputed attorneys’ fees. Rather, the Spera Plaintiffs complained that, by seeking to enforce *868 the contingent fee contracts as written, and by failing to disclоse the conflict of interest between the law firm and its clients prior to December of 1996, FH & G negligently breached its fiduciary duty.
Procedural History and Issues Presented
In February of 1998, the Spera Plaintiffs filed a lawsuit against FH & G in the 61st Judicial District Court for Harris County, Texas, alleging that, by seeking the full amount of attorneys’ fees without disclosing the conflict of interest, the defendants “wholly failed and neglected to properly represent and protect” the polybutylene plaintiffs’ interests. 2 In that regard, the Spera Plaintiffs lodged claims for “fraud, misrepresentation, conflict of interest, breach of fiduciary duty, neglect, negligence, gross negligence, negligence per se, and legal malpractice.” The Spera Plaintiffs complained, in particular, that FH <& G’s “overreaching” conduct constituted an abuse of “the trust and confidence reposed in them” which rose to the level of a fiduciary breach, and so they sought forfeiture of all or part of the attorneys’ fees already paid.
In September of 1998, FH <& G filed a motion for summary judgment arguing that the Spera Plaintiffs’ claims failed as a matter of law for the following reasons: (1) the claims were barred by the doctrine of collateral estoppel becausе the 334th District Court had already considered the propriety of the attorneys’ fee award during the 1996 fairness hearings; (2) the claims were an “impermissible collateral attack” on the November 18, 1996 order entered by the 334th District Court because the Spera Plaintiffs did not appeal that order; (3) the claims were barred by the doctrine of judicial estoppel because of a prior statement made by the Spera Plaintiffs during the course of the lawsuit; (4) the claims were barred because 20,000 of the proposed plaintiffs in the suit had already releаsed their claims stemming from the attorneys’ fee issue by agreeing to settle that dispute; (5) the claims regarding FH & G’s efforts to settle the attorneys’ fee dispute were barred as an “impermissible attack” on the 334th District Court’s November 18, 1996 order; (6) that FH & G’s conduct in offering to settle the attorneys’ fee dispute could not support the Spera Plaintiffs’ claims because the court had already found the settlement “acceptable”; (7) that, because the polybu-tylene plaintiffs received all of the damages sought during the litigation with the manufacturers, the Spera Plaintiffs had not been damaged and therefore could not prevail on their claims against FH & G; and (8) that, because all disputed funds were transferred into an escrow account, the Spera Plaintiffs could not prove they had been damaged by the attorneys’ fee debacle.
In October of 1998, the judge of the 61st District Court entered a summary judgment in FH & G’s favor without specifying the grounds for that ruling. This appeal followed. In their first eight points of error, Appellants challenge each of the grounds recited in FH & G’s motion, arguing that none of them support a summary judgment. Appellants’ ninth point of error alleges that the judge of the 61st District Court erred generally by entering summary judgment in FH
&
G’s favor under the rule set out in
Malooly Brothers, Inc. v. Napier,
Standard of Review: Summary Judgment
Here, FH & G filed its motion for summary judgment under Rule 166a(c) of the Texas Rules of Civil Procedure. The standard for reviewing motions filed under this rule “is whether the successful movant at the trial level carried its burden of showing that there is no genuine issue of material fact and that judgmеnt should be granted as a matter of law.”
KPMG Peat Marwick v. Harrison County Housing Fin. Corp.,
To prevail on summary judgment, a defendant, as the movant, must establish as a matter of law all the elements of an affirmative defense or show that at least one element of the plaintiffs cause of action has been established conclusively against the plaintiff.
See Robles v. Consolidated Graphics, Inc.,
Collateral Estoppel
In its motion for summary judgment, FH & G argued that the Spera Plaintiffs’ claims were barred by the doctrine of collateral estoppel because the attorneys’ fee issue was previously litigated at the fairness hearings before the 334th District Court. In their first point of error, the Spera Plaintiffs contend that the doctrine of collateral estoppel does not apply in this instance.
The doctrine of collateral estop-pel is used to prevent a party from relit-igating an issue that it “previously litigated and lost.”
Quinney Elec., Inc. v. Kondos Entertainment, Inc.,
A reading of the “Final Order” entered by the 334th District Court on Novembеr 18, 1996, shows that it was intended to “resolve the issue of attorney[s’] fees and expenses.” The order observes that the settlement entailed $170 million in cash to be distributed among claimants representing approximately 67,000 property units and, in addition, for replacing the polybutylene plumbing found in 60,000 of those units. The order notes further that FH & G made the following proposal for distributing attorneys’ fees and expenses under the existing contingent fee contracts:
FH & G presented to the court a proposed formula wherein that law firm would receive in addition to the $20 million dollars in expenses referred to above, attorney[s’] fees in the amount of $88.8 million dollars. The attorneyfe’] fee figure was arrived at by taking 40% of the cash portion of the settlement and adding it to 40% of the value of re-plumbs estimated at an agreed upon figure of $72 million dollars, or $1,200 dollars a unit for 60,000 units. Thus the total fees and expenses estimate set for by FH & G was $108.8 million dollars or 64% of the total cash fund available.
The court found that, under the “unique circumstances” present in the polybutylene “mass tort” litigation, such an award of attorneys’ fees and expenses “would be excessive and contrary to the interests of justice.” Accordingly, the court reduced the amount of attorneys’ fees to approximately $33 million and the amount of compensation for expenses to just over $10 million.
We hold that, under these facts, the doctrine of collateral estoppel does not apply. The sole issue before the 334th District Court was whether enforcement of the 40% contingent fee agreements was reasonable as a matter of public policy. In contrast, the issue before the 61st District Court in this lawsuit by the Sрera Plaintiffs is whether FH & G breached its fiduciary duty or engaged in any other wrongful conduct by failing to timely disclose a conflict of interest to the clients. Because the issues presented are separate from those addressed by the trial court during the fairness hearings, the Spera Plaintiffs’ claims are not barred by collateral estoppel.
See Querner v. Rindfuss,
Collateral Attack
FH & G also argued that it was entitled to a summary judgment because, by failing to appeal the 334th District Court’s November 18, 1996 order apportioning attorneys’ fees and expenses, the Spera Plaintiffs’ claims were an “impermissible collateral attack” on the court’s final order. In their second point of error, the Spera Plaintiffs contend that the trial court erred in granting summary judgment on this basis.
“A collateral attack is an attempt to avoid the effect of a judgment in a proceeding brought for some other purpose.” Gus M. Hodges,
Collateral Attacks on Judgments,
41 Tex. L. Rev. 163, 163-64 (1962). A collateral attack is impermissible if it is instituted to interpret a prior
*871
judgment entered by the same court or another court of coordinate jurisdiction.
See, e.g., Martin v. Dosohs I, Ltd.,
Judicial Estoppel
In its motion for summary judgment, FH & G argued that а statement purportedly made during the course of the lawsuit barred the Spera Plaintiffs’ claims under the doctrine of judicial estoppel. The Spera Plaintiffs argue, in their third point of error, that the doctrine of judicial estop-pel does not apply here.
The doctrine of judicial estoppel “bars a party, who has successfully maintained a position in a prior judicial proceeding, from later adopting an inconsistent position, unless he can show the prior statement was made inadvertently due to mistake, fraud, or duress.”
Vinson & Elkins v. Moran,
In this case, FH & G contends that the Spera Plaintiffs’ claims are barred by the doctrine of judicial estoppel because of a sentence found in their “Amended Motion for Class Certification” to the trial court in this case. That sentence states as follows: “All issues оf reasonableness for attorneys’ fees have been determined by orders of the 234th [sic] Judicial District Court.” 3 FH & G maintains further that because the Amended Motion for Class Certification is not a part of the appellate record, the judgment must be affirmed.
We note that the statement found in the Amended Motion for Class Certification is not sworn. 4 See Vinson & Elkins, 946 *872 S.W.2d at 396. Therefore, it does not satisfy all of the requisite elements of judicial estoppel. See id. Accordingly, the Spera Plaintiffs’ third point of error is sustained.
Release
In their fourth point of error, the Spera Plaintiffs contend that it was error to grant summary judgment in FH & G’s favor “on the ground that 20,000 of the proposed plaintiffs in this lawsuit released all claims against the defendant-attorneys related to the disputed attorneys’ fees.” FH & G’s motion for summary judgment argued that, because 20,000 of FH & G’s polybutylene clients agreed to settle and release their claims regarding the disputed attorneys’ fees, the Spera Plaintiffs had also somehow released their claims. FH & G concedes, however, that “none of the Plaintiffs/Appellants herein finalized a release and secured payment of the disputed attorneys’ feеs” that are currently held in escrow, and agrees that this issue would not support a summary judgment. The Spera Plaintiffs’ fourth point of error is therefore sustained.
Correspondence Sent to Plaintiffs
Points of error five and six address the following two pieces of correspondence — between FH & G and its poly-butylene clientele — that were attached to the Spera Plaintiffs’ petition: (1) a December 1996 issue of a newsletter entitled PB Press which was distributed by FH & G to all of its polybutylene clients to announce FH & G’s plans to appeal the 334th District Court’s order reducing the attorneys’ fees; and (2) a letter dated July 7,1997, in which FH & G offered to “resolve” the conflict involving the attorneys’ fees set aside by the judge of the 334th District Court and to settle that matter. In their petition, the Spera Plaintiffs had eom-plained that this correspondence “memorialize[d]” FH & G’s wrongful conduct. In their motion for summary judgment, FH & G argued that this correspondence could not be used to support the Spera Plaintiffs’ claims because the 334th District Court had already determined that the correspondence was “acceptable.” FH & G urged that the Spera Plaintiffs’ claims were an “impermissible attack” on the rulings from the 334th District Court, and that they could not be “forced to relitigate” the propriety of the correspondence following such a determination.
FH & G’s argument that the disputed correspondence cannot be “relitigated” or reviewed because of the 334th District Court’s order is without merit. However, the Spera Plaintiffs are not using the correspondence to launch an impermissible attack on the 334th District Court. Rather, they are using the correspondence to show that they were not informed about the potential conflict of interest and given an opportunity to evaluate whether they should оbtain other counsel. Because FH & G has not shown that it was entitled to summary judgment on these grounds, points five and six are sustained.
Damages
The Speras’ seventh and eighth points of error concern the issue of whether the these plaintiffs have suffered any actual damages. FH & G argued in its summary judgment motion that the Spera Plaintiffs’ claims failed as a matter of law because, given that all had agreed to settle and release their claims over the disputed attorneys’ fees, they suffered no damages. 5 FH & G did not argue that a breach of the fiduciary duty did not occur, nor did it arguе that there was no injury to the attorney client relationship; instead, it argued simply that the Spera plaintiffs suffered no actual damages. FH & G also *873 points out that the Spera Plaintiffs, each of whom participated in the 1995 settlement with polybutylene manufacturers, have “received all eligible damages” in terms of a cash payment or replumbing under the settlement agreement. FH & G argued further that it was entitled to summary judgment because all of the disputed attorneys’ fees were ordered into a court-supervised escrow account pending a resolutiоn of the FH & G’s appeal of the trial court’s order to the First Court of Appeals. FH & G insists, therefore, that all of the Spera Plaintiffs’ claims fail because they cannot establish the essential element of damages.
On appeal, FH
&
G concedes that, in the context of the attorney-client relationship, proof of damages is not required with a request for fee forfeiture in a breach of fiduciary duty claim.
See Arce v. Burrow,
FH
&
G also alleges that a recent opinion by the First Court of Appeals moots the Spera plaintiffs’ claims that FH <& G should have notified them sooner of a potential conflict of interest because it allegedly establishes that they had no actual damages.
See In re Polybutylene Plumbing Litigation,
Thus, if summary judgment was entered on this ground, it was error. See id. The Spera Plaintiffs’ seventh and eighth points of error are therefore sustained with respect to their claim for breach of fiduciary duty.
However, damages are an essential element for all of the othеr claims lodged by the Spera Plaintiffs.
See, e.g., Latham v. Castillo,
The Malooly Point
In their ninth pоint of error, listed as an “issue presented” in the table of contents of the Appellants’ brief, the Spera Plaintiffs complain that the trial court erred by granting summary judgment in the Appellees’ favor under the rule set out in
Malooly Brothers, Inc. v. Napier,
Conclusion
Based on the foregoing, the trial court’s decision to grant summary judgment on the Spera Plaintiffs’ claim for breach of fiduciary duty is reversed and remanded for additional proceedings. However, the trial court’s decision to grant summary judgment as to the Spera Plaintiffs’ remaining claims is affirmed.
Notes
. That appeal, docketed as
William and Lisa Adkins et al. v. Hoechst Celanese Corporation et al.,
No. 01-96-01528-CV, is a consolidation of sixteen appeals from lawsuits filed in eleven Texas counties. Each of those appeals turns on the correctness of the November 18, 1996 order entered by the 334th District Court, which was adopted in other counties as part of the final judgment in those cases. We note that, on March 30, 2000, the First Court of Appeals reversed the 334th District Court’s order.
See In re Polybutylene Plumbing Litigation,
. Initially, Appellants sought to certify their suit against FH & G as a class action of “all persons entitled to an interest in escrowed attorneys’ fees who were represented by Dеfendants in claims resulting from polybutyl-ene pipe failures.” On August 31, 1999, following an interlocutory appeal, this Court affirmed the trial judge’s order denying class certification.
See Spera v. Fleming, Hovenkamp & Grayson, P.C.,
. The fairness hearings were conducted by the judge of the 334th Judicial District Court for Harris County, Texas, and not the 234th.
. Although the Spera Plaintiffs’ Amended Motion for Class Certification is not present in the instant case's appellate record, we take judicial notice of the fact that it is in the *872 record filed before this Court in cause number 14-98-1272-CV, addressing the interlocutory appeal of the trial court's decisiоn to deny class certification.
. As noted above in the discussion on point of error number four, it is undisputed that none of the Spera Plaintiffs have settled or released their claims with FH & G.
. The Spera Plaintiffs appear to claim that they need not show damages to prevail on a breach of contract action because they are also entitled to a fee forfeiture under that theory. As support for that contention, the Spera Plaintiffs rely on the Texas Supreme Court's decision in
Royden v. Ardoin,
