Appellants, thirty-four named class members, their attorney Beverly C. Moore, Jr. and his law firm Moore & Brown (“appellants”) appear before this court in their third appeal, arising from a proposed class action against appellee Ford Motor Company (“Ford”) involving breach of warranty claims. In their present appeal, appellants challenge a trial court order denying their May 2000 motion to dismiss with prejudice and to vacate the trial court’s 1994 voluntary dismissal order. The 1994 order included an award of attorney’s fees and costs as a term and condition of the dismissal without prejudice previously sought by appellants. Judge Steffen W. Graae denied the motion to dismiss with prejudice on two grounds: (1) that appellants were untimely in their decision to opt for a dismissal with prejudice in 2000 in lieu of complying with the terms and conditions of the 1994 order conferring a dismissal without prejudice, and (2) that appellants were precluded under the doctrine of equitable estoppel from contradicting their representations to two other jurisdictions that they intended to pay Ford’s attorney’s fees and costs when quantified. We affirm.
I.
The class action litigation at issue here was filed in this jurisdiction in 1991, the second of four proposed nationwide class action lawsuits filed against Ford for breach of written and implied warranties based on allegations of faulty transmissions, in particular Ford model cars manufactured between 1976 and 1979. Prior to the District of Columbia (D.C.) Superior Court suit, appellants filed a federal suit in August 1981, which was subsequently dismissed on appeal ten years later on jurisdictional grounds when the only named appellant settled with Ford.
Walsh v. Ford Motor Co.,
292 U.S.App. D.C. 82,
When Ford filed a motion to dismiss the Thoubboron complaint as time-barred in March 1991, appellants responded with a motion under Super. Ct. Civ. R. 41(a)(2) to dismiss their claims without prejudice in order to pursue their claims in other jurisdictions. While this motion was pending, appellants filed a similar proposed nationwide class action in Pennsylvania on behalf of the thirty-four Thoubboron plaintiffs in addition to Raymond B. Doutt. Doutt v. Ford Motor Co., No. 212 (Pa. Ct. Common Pleas Philadelphia Co., Apr. 1, 1991). The fourth suit was filed in Illinois on behalf of eighteen of the Thoubboron plaintiffs in addition to others. Portwood v. Ford Motor Co., No. 91 CH 4442 (Ill. Cir. Ct. Cook Co., May 14, 1991). The Pennsylvania and Illinois courts stayed the proposed class action proceedings in 1991 and 1992, respectively, while awaiting the resolution of the Thoubboron case.
In September 1991, Judge Richard A. Levie dismissed
Thoubboron
with prejudice because appellants’ claims were time-barred under District of Columbia law. Appellants appealed, requesting that this court instead direct the trial court to dismiss the claims without prejudice pursuant to Rule 41(a)(2) in order to avoid the potential res judicata effect on appellants’ suits then pending in Pennsylvania and Illinois. Noting that a dismissal with prejudice is a “drastic remedy and should be granted sparingly,” we vacated the trial court’s decision and remanded with instructions that the trial court provide an explanation as to the basis for dismissing the claims with prejudice “[i]n order to facilitate judicial review and to ensure that the trial court’s discretion has been judiciously exercised.”
Thoubboron v. Ford Motor Co.,
In a January 1994 order, Judge Levie granted appellants a voluntary dismissal without prejudice conditioned upon their paying Ford’s attorney’s fees and costs incurred involving work product which would not be useful in related, subsequent litigation between the parties, and indicated that the voluntary dismissal was granted “subject to Plaintiffs’ compliance with the above listed conditions.” He also ordered that Ford submit affidavits and other supporting documents itemizing attorney’s fees and costs to the trial court by February 7, 1994 for quantification of the appropriate amount due to Ford. Appellants were instructed to file a response to Ford’s submission by February 22, 1994. In its February 7, 1994 submission, Ford sought attorney’s fees in the amount of $84,790 and costs in the amount of $3,459.06, for a total of $88,228.06. On March 7, 1994, appellants filed a forty-page opposition to Ford’s request on several grounds — excessiveness in terms of the attorney time billed, that substantial portions of the work product could be reused in Portwood and Doutt, lack of *1208 specificity in terms of the attorney time billed, lack of supporting documentation, and excessive costs — and argued that Ford’s request for attorney fees should be reduced to $16,291. 1
Following the issuance of Judge Levie’s 1994 order, Moore argued to the Pennsylvania and Illinois courts that the stays of those proceedings should be removed because appellants had obtained a voluntary dismissal in Thoubboron and intended to pay Ford’s attorney’s fees and costs as soon as the amount was quantified. Ford requested that the Pennsylvania court maintain the Doutb stay until appellants had actually met their obligation to pay the Thoubboron attorney’s fees and costs. In a March 1994 pleading, Moore represented to the Pennsylvania court that the stay on the Doutb proceeding should be lifted immediately as opposed to when the payments were actually made since appellants fully intended to pay Ford the amount awarded:
Plaintiffs ... advised Ford that. they will, of course, pay whatever attorney fees and costs the Thoubboron court eventually awards, but that amount has not yet been determined and therefore cannot be paid now. Plaintiffs further advised that the residual fee issue which is entirely collateral to the merits of this litigation provides no basis for continuing the Stay (or the Illinois Stay in the Porbwood case ...), even though technically Thoubboron remains “pending” for as long as the fee issue is outstanding. 2
The stay of Doubb was ultimately lifted and, in May 1995, Moore obtained a voluntary dismissal without prejudice from the Pennsylvania court in order to pursue the litigation in Illinois.
In May 1992, the Illinois court originally granted Ford’s request to stay the Porb-wood action pending the outcome of Thoubboron and Doubb. Appellants appealed the stay. In April 1994, following the voluntary dismissals in Thoubboron in the District of Columbia and Doutb in Pennsylvania, Moore represented to the Illinois' appellate court that “these new developments moot the basis for the stay” in Porbwood because
the Thoubboron trial court on remand dismissed the Thoubboron claims without ■prejudice, on condition that plaintiffs pay Ford certain attorney fees and costs, which plaintiffs will do as soon as the amount, which is presently being litigated, is finally determined. A copy of that Order is attached hereto as Exhibit A. 3
The
Portwood
stay was subsequently removed in 1995, and the litigation proceeded in Illinois. In March 1996, the Illinois trial court dismissed
Porbwood
as time-barred and its decision was affirmed on appeal by the Illinois Court of Appeals,
Portwood v. Ford Motor Co.,
Four years after Judge Levie entered his original order granting appellants’ motion for voluntary dismissal without preju *1209 dice and conditioning it on appellants’ payment of Ford’s attorney’s fees and costs, he quantified the amount due to Ford in a July 1998 order, ruling that appellants were jointly and severally liable to Ford for $62,669.16 in attorney’s fees and costs, 4 less the $5,000 already paid by appellants. 5 In August 1998, appellants filed a motion to alter and amend judgment pursuant to Super. Ct. Civ. R. 59(a)(2) and 59(e) with respect to the 1998 order or, alternatively, for a new trial with respect to that order. Appellants also moved under Rule 60(b)(2) to set aside the 1998 order on the basis of new evidence that Ford reused most of the Thoubboron work product in its Portwood briefs. In addition, appellants asserted that if the Illinois Supreme Court affirmed the dismissal of Portwood, “plaintiffs will have the option to simply decline to pay Ford any fees and will consent to having these Thoubboron claims dismissed with prejudice.”
In September 1998, Judge Levie denied appellants’ motion to alter and amend judgment. On appeal, this court upheld that ruling, noting that when the trial court granted appellants’ motion to dismiss without prejudice, the order was expressly conditioned upon appellants paying Ford’s attorney’s fees and costs.
Thoubboron v. Ford Motor Co.,
Less than one month following our ruling in Thoubboron II, appellants next filed the instant motion to dismiss their claims with prejudice and vacate the voluntary dismissal order conditioned upon payment of Ford’s fees and expenses. Appellants argued that the previously obtained voluntary dismissal without prejudice was rendered “worthless” and thus “moot” since they were now precluded from refiling the proposed class action in any other jurisdiction as a result of the 1998 Illinois Supreme Court ruling dismissing Portwood as time-barred. Judge Graae rejected appellants’ mootness argument in his July 2000 order, denying their motion on two grounds. First, Judge Graae ruled that the time for opting for a dismissal with prejudice rather than complying with the terms and conditions of the voluntary dismissal had passed:
The instant case is distinguishable in its procedural history from those cases suggesting that a plaintiff may elect to suffer dismissal with prejudice rather than comply with a condition of payment of the defendant’s attorneys’ fees. Here Plaintiffs reaped the benefit of the dismissal without prejudice by bringing two other lawsuits. In doing so, the proper *1210 time for election was bypassed. The fact that the results of the lawsuits were not to Plaintiffs’ liking does not restore their right to elect a dismissal with prejudice.
Second, he ruled that appellants should not be allowed to avoid their obligation to pay Ford’s attorney’s fees and costs on equitable estoppel grounds, concluding that Ford “relied on Plaintiffs’ representations in Pennsylvania and Illinois by not moving to dismiss them, and now stand to be injured by Plaintiffs’ failure to compensate them for their attorneys’ fees and costs.”
II.
On appeal, appellants argue that the trial court abused its discretion by denying the motion to dismiss their claims with prejudice and to vacate the 1994 voluntary dismissal order conditioned on the payment of Ford’s attorney’s fees and costs. Appellants maintain that they have a right to elect a dismissal with prejudice in lieu of paying Ford since a voluntary dismissal without prejudice is “worthless” to them now that they are precluded from filing the class action in any other jurisdiction after the dismissal of Portwood. Ford responds that appellants benefitted from the voluntary dismissal order when issued in 1994 because that ruling allowed appellants to proceed with cases in Pennsylvania and Illinois that had been stayed in 1991 and 1992, respectively, pending the resolution of Thoubboron. With respect to the equitable estoppel argument, Ford maintains that Judge Levie would not have granted a dismissal without prejudice if appellants had rejected the express condition to pay Ford’s attorney’s fees and costs, and that the Pennsylvania and Illinois courts would not have lifted the stays in those jurisdictions but for appellants’ assurances that they intended to meet the conditions.
A. Rule 41(a)(2)
Rule 41(a)(2) permits a plaintiff, with court approval, to voluntarily dismiss an action. Super. Ct. Civ. R. 41(a)(2);
Washington Metro. Area Transit Auth. v. Reid,
The trial court has the discretion under Rule 41(a)(2) to condition a voluntary dismissal without prejudice “upon such terms and conditions as the Court
*1211
deems proper.” Super. Ct. Civ. R. 41(a)(2). The purpose of the “terms and conditions” clause is “to protect a defendant from any prejudice or inconvenience that may result from a plaintiffs voluntary dismissal.”
Taragan v. Eli Lilly & Co.,
267 U.S.App. D.C. 387, 390,
A plaintiff facing terms and conditions has several alternatives. The plaintiff may accept the voluntary dismissal without prejudice and concomitant conditions, which confers upon defendants “an enforceable judgment which they can execute.” Yo
ffe v. Keller Indus.,
B. Equitable Estoppel
The trial court held that the doctrine of equitable estoppel forecloses appellants from avoiding their obligation to pay Ford’s attorney’s fees and costs because Ford “relied on Plaintiffs’ representations in Pennsylvania and Illinois by not moving to dismiss them, and now stand to be injured by Plaintiffs’ failure to compensate them.” Appellants argue that the trial court improperly carved out an equitable estoppel exception “to the general rule that plaintiffs may opt just not to pay” attorney’s fees and costs. Ford counters that appellants made representations in Pennsylvania and Illinois that they fully intended to pay such fees and costs, that Ford relied upon these assurances, and to allow appellants to now walk away from those representations would result in prejudice to Ford’s position. We agree that the principles of equitable estoppel are applicable here, and affirm the trial court’s decision on that basis. 9
The doctrine of equitable estoppel provides that “a party with full knowledge of the facts, which accepts the benefits of a transaction, contract, statute, regulation, or order may not subsequently take an inconsistent position to avoid the corresponding obligations or effects.”
First American Disc. Corp. v. Commodity Futures Trading Comm.,
343 U.S.App. D.C. 71, 79,
The record supports the trial court’s ruling that appellants should be equitably estopped from avoiding their obligation to pay Ford’s attorney’s fees and costs. First, Ford was the adverse party in the two previous proceedings in both Illinois and Pennsylvania, where appellants made unqualified representations that they would meet the conditions attached to the Thoubboron voluntary dismissal by paying Ford’s attorney’s fees and costs as soon as the amount was quantified. Second, Ford relied on appellants’ representations in both jurisdictions that they fully intended to pay Ford the amount awarded. 11 Were it not for appellants’ representations, Ford clearly would have opposed the lifting of the stay in both the Pennsylvania and Illinois cases until the terms and conditions of the voluntary dismissal were satisfied. At that juncture, had appellants failed to satisfy the terms and conditions of the voluntary dismissal, a dismissal with prejudice would have been the appropriate remedy and would have provided Ford with “all the relief that could have been obtained after a full trial,” and protected Ford from subsequent litigation pursuant to the doctrine of res judicata. 8 James Wm. Moore, MooRe’s Federal Practice § 41.40[3] (3d ed.1997). 12 Finally, Ford suffered injury because Ford would be required to forego payment of its attorney’s fees and costs despite appellants’ ability to proceed with the Doutt and Portwood actions in 1995. 13
To grant appellants’ motion to dismiss with prejudice now, after appellants have pursued their claims in two other jurisdictions and after Ford has borne the risk of this subsequent litigation, would clearly prejudice Ford, a result inconsistent with Rule 41’s purpose in protecting the defendant’s interests in the face of a subsequent, duplicative lawsuit following a voluntary dismissal.
See Colombrito v. Kelly,
Appellants argue that the trial court improperly carved out an equitable estoppel exception to the general rule that plaintiffs may decide against paying a defendant’s attorney’s fees and costs in favor of a dismissal with prejudice. We disagree with this characterization of the trial court’s equitable estoppel rationale and with appellants’ interpretation of the case law concerning the right to opt for a dismissal with prejudice. As discussed above, plaintiffs have the option of withdrawing a voluntary dismissal conditioned as this one was, just as plaintiffs may choose not to comply with the terms and conditions and forego the dismissal without prejudice. However, the case law simply does not permit plaintiffs to exploit the advantage presented by a voluntary dismissal by pursuing the same litigation in other jurisdictions, reneging on unqualified promises to pay the defendant’s attorney’s fees and costs when quantified, and then returning to court for a dismissal with prejudice when all the claims have been dismissed as time-barred in the other jurisdictions.
See McCall-Bey, supra,
Although one means for courts to contend with a plaintiff who fails to comply with the terms and conditions of a voluntary dismissal is to dismiss with prejudice in order to promote the defendant’s desire for finality, such a dismissal is usually reasonable only when this is a meaningful sanction.
See McCall-Bey, supra,
C. Other Issues
Appellants also argue that the 1994 voluntary dismissal order is now “moot,” relying on language in
Thoubboron II, supra,
where we noted that “[w]hile it is possible that the present litigation may become moot at some time in the future as a result (at least in part) of the Illinois ruling, it is not moot yet ... [and, thus,] any suggestion of mootness is at best premature.”
In this appeal, appellants also attempt to revisit the issue of the reasonableness of Ford’s attorney’s fees and costs. Appellants argue that the $63,669 in attorney’s fees and costs are disproportionate in amount when compared to the $36,734 in potential claims of the
Thoubboron
plaintiffs. The reasonableness of attorney’s fees and costs was determined by this court in
Thoubboron II, supra,
For the foregoing reasons, the decision of the trial court is
Affirmed.
Notes
. Plaintiffs’ Opposition to Ford’s Request for Attorney Fees and Costs, filed March 7, 1994.
. Statement of Points and Authorities in Support of Plaintiffs’ Motion to Modify and Con- ■ tinue Stay or, Alternatively, to Voluntarily Discontinue Claims of All Plaintiffs Except Doutt ■without Prejudice, filed March 30, 1994. In a footnote to that pleading, appellants indicated that the document also reflects Plaintiffs’ Opposition to Ford’s Motion to Terminate Stay, filed February 28, 1994.
.Appellants’ Second Motion to Supplement Record, filed April 6, 1994.
. The trial court determined that certain of appellants’ challenges to Ford's submissions concerning attorney’s fees and costs were meritorious because several of the itemiza-tions lacked specificity. As a consequence, the trial court reduced the amount due to Ford from the initial request for $88,228.06 to $62,669.16.
. According to an April 1997 letter from Ford’s counsel to Judge Levie, Moore made a $5,000 payment in December 1996 "to be applied toward satisfaction of the Court’s ultimate order on Ford’s application.”
. We have held that Super. Ct. Civ. R. 41 is substantially identical to the corresponding federal rule, Fed.R.Civ.P. 41 and, thus, we "constru[e] the local rule in light of federal cases interpreting the federal rule.”
Clay v. Faison,
. Indeed, the Eighth Circuit has held that a court's failure to condition a voluntary dismissal upon the plaintiffs payment of attorney’s fees and
costs
may constitute an abuse of discretion.
Belle-Midwest, Inc. v. Missouri Prop. & Cas. Ins. Guar. Assoc.,
. The trial court's decision to permit a voluntary dismissal pursuant to Rule 41(a)(2) is discretionary, and we must uphold its decision unless we find an abuse of discretion.
Washington Metro. Area Transit Auth., supra,
. Because we affirm on the basis of equitable estoppel doctrine, we need not reach the trial court's other basis for denying the motion, that the proper time for appellants to withdraw their motion for voluntary dismissal had passed. In addition, we need not reach Ford’s argument concerning the applicability of the judicial estoppel doctrine, particularly in light of the doctrine's questionable viability in this jurisdiction.
See Konstantinidis v. Chen,
200 U.S.App. D.C. 69, 74,
. The requirements for "privity, reliance, and prejudice” reflects the doctrine’s purpose "to ensure fairness in the relationship between the parties ... [by] preventing] the unconscientious and inequitable assertion or enforcement of claims or rights which might have existed or been enforceable by other rules of law, unless prevented by the estop-pel.”
Konstantinidis, supra,
200 U.S.App. D.C. at 73,
. During oral arguments, Moore did not deny the truth of the representations reflected in those pleadings.
. Ford also argues that, relying on the promise, it did not press Judge Levie for a prompt decision on the amount of the attorney's fees.
.Although not explicitly applying equitable estoppel, the Eleventh Circuit in
McGregor, supra,
. Appellants’ contention on appeal that "there was no possible ‘benefit’ ’’ derived from dismissing their
Thoubboron
claims without prejudice is belied by their own representations before this court in
Thoubboron I, supra,
. Appellants' argument also suffers from its points of comparison. Clearly, in 1994 when the dismissal without prejudice was issued, appellants did not envision that they would be confined to potential claims from only the Thoubboron plaintiffs since the potential existed for the realization of claims from both the Doutt and Portwood actions.
