This is а case of a suitor scorned. Plaintiff-appellant Alternative System Concepts, Inc. (ASC) courted Language for Design Automation, Inc. (LEDA) and forged a short-term distribution relationship. As the couple moved toward a more durable *26 bond, defendant-appellee Synopsys, Inc. acquired LEDA and dashed ASC’s hopes.
The jilted suitor responded aggressively, haling Synopsys into court and claiming, inter alia, misrepresentation and breach of promise. The district court dismissed the former claim early in the proceedings and subsequently granted summary judgment for Synopsys on the latter. ASC appeals. After addressing a number of issues (including an issue of first impression in this circuit concerning judicial estoppel), we affirm.
I. BACKGROUND
We rehearse the facts in the light most favorable to the nonmoving party (here, ASC) and draw all reasonable inferences in that party’s favor. Because there are differences between the ground rules that apply to motions to dismiss as opposed to motions for summary judgment,
compare Chongris v. Bd. of Appeals,
ASC is a New Hampshire corporation involved in the design and marketing of programs used in the production of computer chips. On March 29, 1999, it entered into a letter of understanding (the LOU) with LEDA, a French software designer. In the LOU, LEDA appointed ASC as the exclusive distributor of its Proton product line in the United States for a six-month term commencing April 1, 1999. The parties further declared that they would attempt to “negotiate in good faith a permanent agreement based on experiences during the term of th[e] LOU.” That declaration was purely aspirational; the LOU stated expressly that neither party had any obligation to enter such a permanent agreement.
During the next six months, the two firms engaged in sporadic negotiations. On September 1, 1999, their representatives met in France in hopes of hammering out the details of a permanent arrangement. Although LEDA’s managing dirеctor assured ASC that “all was satisfactory with regard to a permanent agreement,” the parties neither developed nor signed a written contract. Later that month, the parties exchanged e-mails that apparently extended the geographic coverage of the LOU to Canada.
Talks continued past the LOU’s expiration date (September 30, 1999). On October 5, representatives of the two companies met in Florida. LEDA agreed to extend the LOU for a reasonable time pending the completion of negotiations. It also notified a prospective customer that ASC remained the exclusive distributor of LEDA products in the United States and Canada. ASC claims that the parties had by then substantially agreed on the key terms of a permanent distribution relationship, but the fact remains that LEDA balked at signing such an agreement.
In January of 2000, Synopsys (a California-based competitor of ASC) acquired LEDA. It promptly terminated the interim distribution agreement and broke off the negotiations for a permanent relationship. ASC was left out in the cold.
ASC lost little time in bringing this diversity action against Synopsys in New Hampshire’s federal district court. See 28 U.S.C. § 1332(a). Its first amended complaint charged that LEDA had been dere *27 lict in its duty to negotiate a permanent distribution agreement in good faith; that LEDA had intentionally misrepresented the nature of its interactions with Synop-sys; that LEDA had flouted an implied covenant of good faith and fair dealing; and that Synopsys bore responsibility for these transgrеssions as LEDA’s successor in interest. Finally, the first amended complaint charged Synopsys, in its own right, with having interfered with ASC’s advantageous contractual relations.
Synopsys moved to jettison the complaint for failure to state claims upon which relief could be granted.
See
Fed. R.Civ.P. 12(b)(6). On August 2, 2001, the district court dismissed the misrepresentation claim on the ground that ASC had not pleaded misrepresentation with the requisite particularity.
ASC v. Synopsys, Inc.,
No. 00-546,
In order to put the arguments on appeal into workable рerspective, we pause to provide additional detail anent the lower court’s treatment of ASC’s breach of contract claim. Count I of the first amended complaint alleged that “Synopsys/LEDA breached its agreement to negotiate a permanent agreement in good faith and to honor the Canadian distributorship.” In support of its motion to dismiss, Synopsys argued in relevant part that, to the extent this claim was premised on an oral contract entered into between the parties following the execution of the LOU, it was barred by the statute of frauds. See N.H.Rev.Stat. Ann. § 506:2 (providing that “[n]o action shall be brought ... upon any agreement ... that is not to be performed within one year from the time of making it, unless such ... agreement ... is in writing”). In its opposition, ASC clarified that it was “not claiming that [LEDA/Synop-sys] breached an agreement to enter into a long term contract.” Rather, its breach of contract claim was “that LEDA breached its agreement to negotiate in good faith” as required by the LOU.
The district court took ASC at its word. Noting that ASC had explicitly abandoned any claim that the parties had entered a subsequent oral agreement, the court treated ASC’s cause of action as one “that LEDA breached its contractual obligation to make a good faith effort to negotiate a permanent marketing agreement that initially covered the United States and later was amended to include Canada.”
ASC I,
By the time that discovery had run its course and the parties had gotten around to filing cross-motions for summary judgment, ASC had experienced an epiphany. In its summary judgment papers, it alleged that on October 5, 1999, the parties entered into an oral distribution agreement covering the United States and Canada. It also averred that LEDA/Synopsys subsequently breached this permanent arrangement. , Synopsys vociferously objected to this changed tune. It maintained *28 that this approach evinced a new and inconsistent theory; that, throughout the litigation, ASC had construed its breach of contract claim as a claim for breach of a duty to negotiate in good faith; and that this tergiversation resulted in a theory that fell outside the purview of the first amended complaint.
The district court agreed with Synop-sys’s assessment. It invoked the doctrine of judicial estoppel, pointing out that ASC had obtained an “advantage by contending in opposition to Synopsys’s motion to dismiss that its breach of contract claim was premised on an alleged breach of the LOU, rather than a subsequent oral agreement to make the LOU permanent.”
ASC II,
On appeal, ASC contends that the lower court erred in (i) dismissing its misrepresentation claim, (ii) refusing to allow a further amended complaint designed to cure defects in the misrepresentation count, and (iii) invoking the doctrine of judicial estoppel to bar the breach of contract claim that it wished to propound on summary judgment. 2 Synopsys, by motion, asks us to (i) dismiss the appeal, and (ii) award sanctions against ASC. We address these points below, starting with Sy-nopsys’s motion to dismiss, then confronting ASC’s asseverational array, and ending with a consideration of the request for sanctions.
II. THE MOTION TO DISMISS THE APPEAL
While this case was pending in the district court, Synopsys filed a California state court action accusing ASC of conspiracy and unfair business practices. On April 1, 2003 — shortly after the institution of this appeal — thе parties reached at least a tentative settlement in the California action. There is some indication that the terms of the settlement contemplated the dismissal of the earlier (New Hampshire) action. After Synopsys encountered resistance from ASC with respect to implementing the supposed settlement, it asked the California court to enter judgment pursuant to the settlement agreement. The court obliged, albeit without discussion, entering judgment ex parte on September 11, 2003.
Citing these facts, Synopsys invites us to dismiss this appeal as moot and/or barred by the doctrine of res judicata. 3 ASC counters by asserting that the settlement was never consummated. It also contends that the California judgment was entered without proper notice (and is, therefore, void).
We decline Synopsys’s invitation to short-circuit this appeal. The record and briefing before us are too skimpy to allow a definitive determination as to either the status or scope of the ostensible settlement. By like token, the record is inadequate to permit us to assess the res judi-
*29
cata effect of the California judgment. Given the need for more information, we deem it prudent to sidestep the late-emerging res judicata issue and proceed directly to the merits.
See, e.g., Henry v. Connolly,
III. THE MISREPRESENTATION CLAIM
ASC assigns error to both the district court’s dismissal of its misrepresentation claim and to the court’s subsequent “failure” to allow a curative amendment. These remonstrances need not occupy us for long.
A. Applicable Legal Standards.
We review de novo a trial court’s allowance of a Rule 12(b)(6) motion to dismiss.
LaChapelle v. Berkshire Life Ins. Co.,
Federal civil practice is based on notice pleading. Thus, “[gjreat specificity is ordinarily not required to survive a Rule 12(b)(6) motion.”
Garita Hotel Ltd. P’ship v. Ponce Fed. Bank,
B. The Original Claim.
ASC’s first amended complaint alleged in substance that LEDA failed to disclose that merger talks were ongoing between it and Synopsys, but, rather, downplayed the discussions and characterized the contemplated relationship as merely a “technical partnership” that would not affect the outcome of the ASC-LEDA negotiations. ASC further alleged that it relied on these knowingly false representations to its detriment.
5
Despite the
*30
fervor with which ASC denounced this treachery, it did not provide any details as to who allegedly uttered the misleading statements, to whom they were made, where they were made, when they occurred, and what actions they engendered.
See ASC I,
C. The Curative Amendment.
ASC’s fallback position is as insubstantial as a house built upon the shifting sands. It notes that, after the district court had dismissed the misrepresentation claim for want of specificity, it moved for leave to refile, in a further amended complaint, a more particularized version of the claim. The district court denied this request on February 14, 2003, and ASC now calumnizes that order.
This challenge is based on a half-truth. Although ASC did seek leave to file a curative amendment, it unilaterally withdrew that motion before the court reached the matter. A party who voluntarily withdraws a motion prior to judicial consideration cannot later claim that the court’s pro forma denial of the withdrawn motion constitutes reversible error.
See Baty v. United States,
IV. THE BREACH OF CONTRACT CLAIM
The district court, invoking the doctrine of judicial estoppel, consigned ASC’s breach of contract claim to the scrap heap. ASC
II,
A. Applicable Legal Standards.
We review the district court’s disposition of a motion for summary judgment de novo, scrutinizing the facts in the light most favorable to the nonmoving party.
See Garside,
This court has not yet had occasion to determine the appropriate standard for reviewing a trial court’s application of the doctrine of judicial estoppel.
See Gens v. Resolution Trust Corp.,
First, the Supreme Court has explained that “judicial estoppel is an equitable doctrine invoked by a court at its discretion.”
*31
New Hampshire v. Maine,
The fact that this case arises in the summary judgment context does not affect our decision to review the trial court’s determination for abuse of discretion. Although there may seem at first blush to be some tension between the plеnary review afforded to a summary judgment ruling and the deferential review of a threshold judicial estoppel determination, that tension is more apparent than real. Most evidentiary determinations are reviewed for abuse of discretion,
see, e.g., Colasanto v. Life Ins. Co. of N. Am.,
The abuse of discretion standard is familiar. We will not overturn a nisi prius court’s discretionary decision unless it plainly appears that the court committed a clear error of judgment in the conclusion it reached upon a weighing of the proрer factors.
In re San Juan Dupont Plaza Hotel Fire Litig.,
B. Choice of Law.
There is a potential choice of law problem lurking in the interstices of this case. A federal court sitting in diversity jurisdiction is obliged to apply federal procedural law and state substantive law.
Hanna v. Plumer,
Having noted this question, we swiftly lay it to one side. The parties have addressed the judicial estoppel issue on thе frank assumption that federal standards control and the district court operated on that assumption.
See ASC II,
We add, moreover, that we would likely reach this same conclusion even without the parties’ acquiescent behavior. It has long been held that federal courts may bypass conflicting state rules of decision in favor of federal standards when positive considerations, such as the presence of a strong federal policy, militate in favor of employing federal standards.
Byrd v. Blue Ridge Rural Elec. Coop.,
C. The Doctrine of Judicial Estoppel.
“As a general matter, the doctrine of judicial estoppel prevents a litigant from
*33
pressing a claim that is inconsistent with a position taken by that litigant either in a prior legal proceeding or in an earlier phase of the same legal proceeding.”
InterGen N.V. v. Grina,
The contours of the doctrine are hazy, and there is no mechanical test for determining its applicability.
See New Hampshire,
While it is not a formal element of a claim of judicial estoppel, courts frequently consider a third factor: absent an estop-pel, would the party asserting the inconsistent position derive an unfair advantage?
Id.
at 751,
Synthesizing these various points, we recently concluded that, in a prototypical case, judicial estoppel applies when “a party has adopted one position, secured a favorable decision, and then taken a contradictory position in search of legal advantage.”
InterGen,
D. Application of the Doctrine.
The district court pronounced this to be “precisely the case for which the doctrine of judicial estoppel was created.”
ASC II,
In its opposition to Synopsys’s motion to dismiss, ASC asserted unequivocally that it was “not claiming that defendant ] breached an agreement to enter into a long term contract,” but, rather, its contract claim was “that LEDA breached its agreement to negotiate in good faith.” This was an unambiguous claim for breach of the LOU — no more and no less — and by characterizing the claim in that fashion, ASC danced out of reach of Synopsys’s statute of frauds defense. Having skirted that pitfall, ASC then adopted a vastly different position. In its objection to Sy-nopsys’s motion for summary judgment, it asserted that its breach of contract claim related not to the LOU but to “a permanent [oral] agreement ... entered into by LEDA and ASC.”
These positions are totally inconsistent. ASC’s argument on summary judgment directly contradicts its prior disclaimer of a breach of contract theory based on an alleged parol agreement. While “holding a litigant to his stated intention not to pursue certain claims is different from the ‘classic’ case of judicial estoppel,” such inconsistencies may present an even
“stronger
argument than do the classic cases for application of the doctrine.”
Patriot Cinemas,
The second element in the judicial estop-pel calculus is present in spades. There is no question but that the district court bought what ASC was selling the first time around. In its order denying Synopsys’s motion to dismiss the breach of contract claim, the court stated:
Synopsys mistakenly assumes that ASC is claiming a breach of an oral agreement to grant it an exclusive marketing agreement.... It then challenges this purported claim based on the statute of frauds. In reality, ASC is claiming that LEDA breached its contractual obligation to make a good faith effort to negotiate a permanent marketing agreement that initially covered the United States and later was amended to include Canada.
ASCI,
To cinch matters, ASC — if allowed to pursue its nascent oral contract theory at summary judgment — would have gained an unfair advantage. Relying on ASC’s prior representation, Synopsys conducted discovery under the warranted assumption that it faced a charge of failing to negotiate in good faith as called for by the LOU. The factual predicate and legal elements of that charge are materially different from the factual predicate and legal elements of the charge that ASC attempted to advance at summary judgment. Synopsys had every reason to assume, based on ASC’s previous statements, that the oral contract theory was not in the case. The unfairness is apparent. Had the lower court allowed ASC to go forward with its revisionist claim, it would have been sanctioning what amounted to a sneak attack.
Given this background, we cannot fault the district court’s determination that ASC was playing fast and loose. The court’s rescript paints a convincing picture of a
*35
litigant who took one position, used that position to its advantage at the motion to dismiss stage, and later attempted to switch horses midstream to revive a previously abandoned (and flatly inconsistent) claim.
See ASC II,
In a desperate effort to blunt the force of this reasoning, ASC mounts two additional arguments. First, it maintains that applying judicial estoppel in this case would countermand its right to plead in the alternative. See Fed.R.Civ.P. 8(e)(2). In ASC’s view, its first amended complaint should be read as alleging, in the alternative, that LEDA/Synopsys not only breached a duty, rooted in the LOU, to negotiate a permanent agreement in good faith, but also entered into and subsequently breached an oral distribution agreement.
This is artful dodging. Like the Fourth Circuit,
Allen v. Zurich Ins. Co.,
ASC’s final asseveration is that its conduct should be excused because its shift in position was attributable to evidence unearthed during the course of pretrial discovery. To support this asseveration, it points to the deposition of its president, Carl Karrfault, taken in 2002 (well after the denial of the motion to dismiss), during which Karrfault offered an account of the October 5 negotiations that tends to show the formation of a permanent distribution contract.
This is smoke and mirrors. We acknowledge that, in limited circumstances, courts have recognized a good faith exception to the operation of judicial estoppel.
See, e.g., Chaveriat v. Williams Pipe Line Co.,
In this instance, ASC cannot colorably lay claim to the exception'. The newly discovered evidence to which it adverts consists of the deposition testimony
of its own president.
When a corporation takes a litigation position, we think it both sensible and fair to impute to it the knowledge of its chief executive officer.
See United States v. Josleyn,
Our decision that the district court acted within the realm of its discretion in estop-ping ASC from claiming a breach of an oral contract effectively ends this aspect of the case. On summary judgment, ASC abandoned its earlier “failure to negotiate in good faith” theory and the estoppel left it without an arguable ground for opposing Synopsys’s motion. Hence, the district court acted appropriately in entering bre-vis disposition for Synopsys on the breach of contract count.
V. THE MOTION FOR SANCTIONS
Synopsys moves for sanctions against ASC and its counsel based upon three theories: (i) that ASC continued to prosecute its appeal even after the appeal became hopeless; (ii) that ASC made misrepresentations in its brief and withheld material facts from this court; and (iii) that ASC violated 1st Cir. R. 30(b)(1) by refusing to cooperate with Synopsys in preparing the joint appendix. Although the question is not free from doubt, we deny the motion.
A. Frivolousness.
Appellate sanctions are a means of discouraging litigants and their lawyers from either wasting an adversary’s time and resources or burdening the court with obviously groundless appeals.
See Transnat’l Corp. v. Rodio & Ursillo, Ltd.,
“An appeal is frivolous ... when the appellant’s legal position is doomed to failure — and an objectively reasonable litigant should have realized as much from the outset.”
Toscano v. Chandris, S.A.,
In this case, ASC’s appeal was arguable when taken. Even after the proceedings in California ripened into a judgment, significant questions remained regarding the status of the supposed settlement, the scope of the statе court litigation, and the efficacy of the resulting judgment.
See supra
Part II. These uncertainties cast doubt over whether this appeal had become a dead man walking. That doubt undermines the claim that persisting in the appeal is sanctionable.
See, e.g., Ins. Co. of West v. County of McHenry,
B. Material Misstatements.
Synopsys’s exhortation that we should impose sanctions on ASC for material omissions in its appellate brief raises a close question. This exhortation relates largely to ASC’s argument concerning the
*37
trial court’s denial of its motion to amend the misrepresentation count.
See supra
Part III(C). Synopsys is correct in pointing out that ASC failed to mention in its brief that it had opted to withdraw its motion to amend before the district court denied that motion. We have indicated before that brazen misrepresentatiоns in an appellant’s brief can justify the imposition of sanctions.
Thomas v. Digital Equip. Corp.,
ASC’s explanation is that the district court never formally ruled on its motion to withdraw the misrepresentation count, leading it to assume that the withdrawal had no legal significance. This is less an explanation than a lame excuse, and we find it wholly inadequate. We note, however, that Synopsys’s other misstatement claims lack force. That is significant because the misrepresentation claim was a sideshow — not the main event — and the misleading omission was so easily exposed that it caused neither Synopsys nor this court an iota of extra work. Courts may, as a matter of discretion, decline to impose sanctions.
See, e.g., Oakville Dev. Corp. v. FDIC,
C. Noncompliance with Local Rules.
Synopsys’s final ground for sanctions relates to 1st Cir. R. 30(b)(1). That rule provides in pertinent part that “[t]he parties are encouraged to agree on the contents of the appendix.” Id. It then provides for various steps that must be taken in the absence of an agreement.
In the last analysis, the rule merely encourages cooperation; it does not mandate it. Moreover, experience teaches that the encouraged cooperation invariably entails a certain amount of pulling and hauling. As to the alternative steps that ASC was expected to take in the absence of an agreement, the record consists mostly of finger-pointing and is insufficient to allow us to assess the magnitude of the claimed violations. Finally, the rule imposes correlative obligations on an appellee, and the record on appeal is too sparse to warrant pinning the blame for transgressions exclusively on ASC.
Cf. Quinones-Pacheco v. Am. Airlines, Inc.,
VI. CONCLUSION
We need go no further. For the reasons alluded to above, we deny Synopsys’s motion to dismiss this appeal; affirm the district court’s decision to dismiss ASC’s misrepresentation claim and to deny the subsequent motion to amend that claim; uphold the entry of summary judgment on the breach of contract claim; and decline to impose sanctions. Withal, we direct that costs be taxed in favor of Synopsys (as the prevailing party).
So Ordered.
Notes
. In other pretrial rulings, the district court dismissed ASC’s implied covenant claim and granted summary judgment for Synopsys on ASC's interference claim. ASC has not appealed from either of these decisions, so we need not probe them more deeply.
. ASC also makes a perfunctory attempt to assert a theory of promissory estoppel. This theory was not presented to the district court in the summary judgment proceedings. Accordingly, we deem the argument unpre-served.
See Teamsters Union v. Superline Transp. Co.,
. Synopsys premises both mootness and res judicata on the same series of events. Since Synopsys directs virtually all of its legal argumentation to res judicata, we use that label to embrace both concepts.
. We say usually” because there may be occasional exceptions, owing to extraordinary circumstances.
See, e.g., Corley v. Rosewood Care Ctr., Inc.,
. Under New Hampshire law, the elements of a fraudulent misrepresentation claim are:
*30
"(1) the defendant misrepresented a material fact to the plaintiff, knowing it to be false; (2) the defendant did so with fraudulent intent that the plaintiff act on it; and (3) that the plaintiff, without knowledge of its falsity, detrimentally relied on the misrepresentation.”
