This case presents the issue of the circumstances under which leave will be granted to permit an interlocutory appeal from a district court’s decision on class certification pursuant to the recently enacted Rule 23(f) of the Federal Rules of Civil Procedure (“Rule 23(f)”).
Plaintiffs commenced a class action suit in 1996 against, inter alia, Sumitomo Corporation (“Sumitomo”), Morgan Stanley & Co. (“Morgan Stanley”), Merrill Lynch & Co. (“Merrill Lynch”), and Global Minerals and Metals Corporation (“Global”), alleging that the defendants conspired to manipulate the prices of copper futures contracts traded on the COMEX division of the New York Mercantile Exchange from June 24, 1994 through June 15, 1996, in violation of the Racketeer Influenced and Corrupt Organizations Act (“RICO”), 18 U.S.C. § 1961 et seq., and the Commodity Exchange Act (“CEA”), 7 U.S.C. § 13(a)(2). The United States District Court for the Southern District of New York (Milton Pollack, Senior Judge) certified a plaintiffs class consisting of more than 20,000 copper futures contract traders who had executed trades over a discontinuous 27-month period.
Defendants-petitioners Credit Lyonnais Rouse, Ltd. and Credit Lyonnais, S.A. (collectively the “CL defendants”) move (1) pursuant to Rule 23(f) and Federal Rule of Appellate Procedure 5, for leave to appeal from that order, and (2) pursuant to Rule 23(f) and Federal Rule of Appellate Procedure 8, for a stay of trial proceedings pending the resolution of such an appeal. The CL defendants were supported by a brief filed by amicus curiae Futures Industry, Inc., an industry association of which the CL defendants are members. We denied leave to appeal by an order entered on September 26, 2000, and now take this opportunity to explain that ruling and the standard that we applied and will apply in the future to petitions seeking leave to appeal a district court’s grant or denial of class certification under Rule 23(f).
BACKGROUND
After plaintiffs filed a motion for class certification under Rule 23(b)(3), Sumito-mo, Morgan Stanley, and Merrill Lynch entered into settlement agreements with the class plaintiffs.
Global refused to settle and opposed class certification. Specifically, Global contended that (1) the class plaintiffs could not establish the predominance of common issues required by Rule 23(b)(3) because they could not prove that the prices in all of the copper futures contracts at issue
In its order certifying the class under Rule 23(b)(8), the district court rejected Global’s contentions. The district court determined that common issues predominated because: (1) the class plaintiffs were not required to prove their claims until trial, at which time, experts on both sides agreed, the class plaintiffs had “a reasonable probability” of proving their claims; (2) the question of individual damages was irrelevant to the liability phase of trial and could readily be resolved at the damages phase of trial by splitting the class into various sub-classes as permitted by Rule 23(c)(4)(B); and (3) both buyers and sellers had a common interest in proving the existence of the conspiracy and price artificiality, and any conflicting interests with respect to damages could be resolved through sub-classes in the damages phase of trial. See id. The district court also found that typicality was satisfied because “every class member purchased or sold the same fungible copper futures contract in the same centralized Comex market” and was affected by “the same alleged conspiracy to manipulate copper prices.” Id. at 94-95.
Global thereafter entered into a settlement agreement with the class plaintiffs. The district court approved all the above-noted settlement agreements. See In re Sumitomo Copper Litigation,
Affcer the class was certified, but before these settlements were approved, the class plaintiffs filed an amended complaint adding the CL defendants. In addition to the claims previously asserted, the amended complaint added a common-law fraud claim and extended the class period to include copper futures contract purchases from June 24, 1993 to June 15, 1996. The CL defendants moved to dismiss the amended complaint on the grounds that (a) it failed to state a claim upon which relief could be granted under RICO, and (b) claims arising before April 25, 1995 were barred by the statute of limitations. In denying the motion, the district court held, inter alia, that plaintiffs were not foreclosed from proving at trial that the statute of limitations was equitably tolled due to defendants’ alleged fraudulent concealment. See In re Sumitomo Copper Litigation,
On August 2, 2000, over the CL defendants’ opposition, the district court granted plaintiffs’ certification motion and certified the proposed class for the periods of June 24, 1993 to September 24, 1993, and June 24, 1994 to June 15, 1996. See In re Sumitomo Copper Litigation,
DISCUSSION
A. Federal Rule of Civil Procedure 23(f)
Federal Rule of Civil Procedure 23(f), which became effective December 1, 1998, provides:
*138 Appeals. A court of appeals may in its discretion permit an appeal from an order of a district court granting or denying class action certification under this rule if application is made to it within ten days after entry of the order. An appeal does not stay proceedings in the district court unless the district judge or the court of appeals so orders.
Fed.R.Civ.P. 23(f). According to the committee notes, courts of appeals have “unfettered discretion” to authorize an appeal under Rule 23(f):
Permission to appeal may be granted or denied on the basis of any consideration that the court of appeals finds persuasive. Permission is most likely to be granted when the certification decision turns on a novel or unsettled question of law, or when, as a practical matter, the decision on certification is likely dispositive of the litigation.
Fed.R.Civ.P. 23(f) committee notes. Although we have recently authorized appeals under Rule 23(f), see, e.g., Daniels v. City of New York, No. 01-7649 (2d Cir. May 1, 2001); Potchin v. Prudential Home, No. 00-7828 (2d Cir. July 13, 2000), we have yet to explicate the standard under which Rule 23(f) petitions should be reviewed.
The Seventh Circuit, the first to consider the question, identified two categories of cases appropriate for review under Rule 23(f). See Blair v. Equifax Check Servs., Inc.,
The second category of cases are those in which the class certification order implicates an unresolved legal issue concerning class actions. See id. at 835. Observing that “the more fundamental the [legal] question and the greater the likelihood that it will escape effective disposition at the end of the case, the more appropriate is an appeal under Rule 23(f),” the Seventh Circuit concluded that the party seeking leave in such a case had to demonstrate, at minimum, that an immediate appeal would contribute to the development of the law of class actions. Id.; see also Richardson Electronics, Ltd. v. Panache Broadcasting of Pa., Inc.,
The certification order at issue in Blair implicated an unresolved legal issue, namely whether the district court erred in certifying the class when, in a separate overlapping class action suit, the defendant had agreed to settle on the condition that further class action suits would be prohibited. See Blair,
After the decision in Blair, the First and Eleventh Circuits weighed in, agreeing with the Seventh Circuit’s standard for discretionary review, but somewhat refining the grounds that would warrant such review. The First Circuit noted that, with respect to the second category of cases, the legal issue had to be “important to the particular litigation as well as important in itself and likely to escape effective review if left hanging until the end of the case.” Waste Mgmt. Holdings, Inc. v. Mowbray,
In Prado-Steiman v. Bush,
In line with our sister circuits, we hold that petitioners seeking leave to appeal pursuant to Rule 23(f) must demonstrate either (1) that the certification order will effectively terminate the litigation and there has been a substantial showing that the district court’s decision is questionable, or (2) that the certification order implicates a legal question about which there is a compelling need for immediate resolution.
Our determination of whether the district court’s decision is sufficiently questionable to warrant interlocutory review will be tempered by our longstanding view that the district court is often in the best position to assess the propriety of the class and has the ability, pursuant to Rule 23(c)(4)(B), to alter or modify the class, create subclasses, and decertify the class whenever warranted. Cf. Robidoux v. Celani,
We anticipate, therefore, that the standards of Rule 23(f) will rarely be met. This approach will prevent the needless erosion of the final judgment rule and the policy values it ensures, including efficiency and deference. See, e.g., Aluminum Co. of Am. v. Beazer E., Inc.,
Finally, we note that parties should not view Rule 23(f) as a vehicle to delay proceedings in the district court. While the rule gives both the district court and the court of appeals discretion to stay the proceedings, we hold that a stay will not issue unless the likelihood of error on the part of the district court tips the balance of hardships in favor of the party seeking the stay.
B. Application of Rule 23(f) Standard
The instant case does not meet any of the requirements of Rule 23(f) set forth above.
1. Death Knell Review
We accept, for the purposes of this case, petitioners’ assertion that class certification will effectively terminate the litigation because it will force them to settle the case rather than risk trial. We nevertheless find that a death knell review is not warranted because petitioners have failed to make a substantial showing that the district court’s decision to grant certification is questionable.
In their petition, the CL defendants contend that the certification order is questionable because: (1) the unprecedented length of the class period in the commodities market context makes it “inconceivable that common questions can predominate and that such claims can be tried in a manageable manner”; (2) the language used in the certification order indicates that the district court impermis-sibly relied on forced settlement as a basis for finding the class manageable; (3) the determination of whether each class plaintiff incurred an injury “requires highly individualized proof, necessarily focusing on a determination of the level of price artificiality (if any) at the moments each class member opened and closed a futures position”; (4) the class plaintiffs must prove that the CL defendants’ conduct at each of those moments was the cause of an ar
The CL defendants have overstated their case. Taking the last point first, they suggest that the district court’s decision is questionable because it failed sufficiently to justify the certification at issue. The district court, however, relied extensively on its earlier certification order in which it had already considered and rejected many of the arguments raised by the CL defendants in responding to Global’s previous opposition to class certification. See Sumitomo III,
Similarly, the district court had previously considered and -rejected the argument that class plaintiffs had to demonstrate at the moment of certification that price artificiality could be proved at trial, reasoning that the ability to prove artificiality “is a matter to be ascertained by trial and not for a determination as to the appropriateness of class certification.” See Sumitomo I,
Also lacking in merit is the CL defendants’ contention that the district court’s decision is questionable because it imper-missibly relied on forced settlement as a basis for finding the class manageable. The CL defendants base their argument on the district court’s statement in its August 10, 2000 certification order that
[t]his Court has considered all of the objections of the CL defendants regarding the manageability of maintaining this action as a class action. The Court reduces the class proposed by plaintiffs by nine months in length, and finds the Class defined in paragraph 1 of this Order to be manageable. In re Sumitomo Copper Litigation, supra,182 F.R.D. at 97 (this Court earlier certified a two year class which was thereafter extensively prosecuted, settled, notice was sent to the class, and final judgment was entered without any management difficulties).
August 10, 2000 Order at 5. In its opinion granting the motion for class certification, however, the district court acknowledged that the CL defendants “raise an arguable question [as to] the matter of manageability.” Sumitomo III,
2. Compelling Question of Law
The CL defendants also argue that leave to appeal from the certification order should be granted because there are questions of law about which there is a compelling need for immediate resolution. Specifically, they claim that the district court erred in certifying the class because: (1) the “presumption of reliance under the fraud-on-the-market theory” cannot be maintained with respect to the common-law fraud claims in light of Securities Investor Protection Corp. v. BDO Seidman, LLP,
The CL defendants’ assertion that the theory of “fraud on the market” cannot be used to satisfy the reliance requirement of a common-law fraud claim under New York law appears to present an open question. Our research indicates that the New York Court of Appeals has never addressed the issue while New York’s lower courts have come to different conclusions. Compare Ackerman v. Price Waterhouse,
We also decline to review the CL defendants’ contention that portions of plaintiffs’ claims are barred by the statute of limitations. The district court held that the issue of whether the limitations period was tolled by the defendants’ alleged fraudulent concealment was a factual issue to be determined at trial. See Sumitomo III,
CONCLUSION
Upon consideration of the present petition, we conclude that the CL defendants have failed either to make a substantial showing that the district court’s certification order is questionable to warrant a death knell review or to demonstrate that the decision implicates a legal question about which there is a compelling need for immediate resolution, and have otherwise failed to persuade us that an immediate appeal is necessary. Accordingly, we deny the petition for leave to appeal and deny as moot the motion for a stay.
