This case involves the intersection of the ADEA statute of limitations and the special tolling rules which may apply when the plaintiffs are within a class alleged but not certified in earlier ADEA actions. The plaintiffs are eleven people, all over 40 years old, who lost their management level jobs at The Ground Round. In all, members of this group, represented by the same counsel, have filed four different actions accusing Ground Round of age discrimination. If this, the fourth action, is untimely, then the district court correctly entered summary judgment.

This action is untimely if the plaintiffs' otherwise concededly untimely claims are not saved by the fact that there were two prior lawsuits with class action allegations, and plaintiffs were within the classes alleged. We hold that this stacking of two class actions does not save the plaintiffs' claims. We affirm.

This is the fourth lawsuit by former Ground Round employees alleging class-wide age discrimination by Ground Round. Each action described the same set of events1 and asserted essentially the same class. The first such action, Dionne v. Ground Round, was filed in Massachusetts state court and removed by Ground Round to federal court based on plaintiffs' ADEA claims. The Dionne plaintiffs sought class certification, which the district court denied on July 6, 1994. The Dionne plaintiffs then voluntarily dismissed their ADEA claims and successfully moved to remand the case to state court.

The second action, Halligan v. Ground Round, was filed in federal district court on November 22, 1993. As of the time the complaint in this case was filed, the Halligan plaintiffs still had not moved for class certification.2 On December 21, 1995, after the complaint in this case was filed, the Halligan plaintiffs voluntarily dismissed their ADEA claims and the action was dismissed.

After the district court denied class certification in Dionne, but before remand to state court, several members of the putative class sought to intervene in that action. The district court denied their motion, at which point the would-be intervenors filed the third related lawsuit, Winspear v. Ground Round, in state court alleging only state-law causes of action. Seven of the plaintiffs in the Winspear action are plaintiffs here. The Massachusetts Superior Court granted Ground Round's motion for summary judgment in Winspear without reaching the merits.3

Plaintiffs here filed this action against Ground Round on October 6, 1995, alleging that Ground Round instituted a company-wide policy of dismissing older management workers and replacing them with younger workers, in violation of the ADEA. Plaintiffs claimed to represent a class of similarly situated former Ground Round employees.4

The plaintiffs here claim to represent the class of "all past, present and future managerial employees of Ground Round, who have been or may be terminated from their employment on the basis of age," not including those who left Ground Round's employ before January 1, 1990. The Dionne, Halligan, and Winspear complaints defined the putative class in a nearly identical manner.

Ground Round moved for summary judgment on several grounds. First, relying on the Massachusetts Superior Court's dismissal of the Winspear action to which seven of the present plaintiffs were parties, Ground Round argued that the claims of those seven plaintiffs5 were barred by the doctrine of res judicata. The district court rejected this argument based on its conclusion that the Winspear action was dismissed for procedural reasons, and not on its merits.

Defendant's second argument for summary judgment was that the claims of seven plaintiffs6 were barred because those plaintiffs failed to file administrative charges with the EEOC within 300 days of their discharge from employment, as required by the ADEA.7 The seven plaintiffs admit that they did not file administrative charges within the requisite time period, but argue that their claims are nevertheless saved by the "single-filing rule" adopted by the majority of circuits, but not yet addressed by this circuit. That rule, also referred to as "piggybacking," permits plaintiffs who have failed to file administrative charges, or who have filed untimely charges, to "piggyback" on the timely-filed charges of other plaintiffs, provided the timely-filed charge gives the EEOC and the employer adequate notice of allegations of class-wide discrimination. See Grayson v. K Mart Corp., 79 F.3d 1086, 1101-02 (11th Cir.1996); Howlett v. Holiday Inns, Inc., 49 F.3d 189, 194 (6th Cir.1995); Anson v. University of Tex. Health Science Ctr., 962 F.2d 539, 541-42 (5th Cir.1992); Tolliver v. Xerox Corp., 918 F.2d 1052, 1057-59 (2nd Cir.1990); Kloos v. Carter-Day Co., 799 F.2d 397, 400-401 (8th Cir.1986).8

Defendant also argued that even if the single-filing rule were adopted, plaintiffs' claims would still be barred because the timely-filed administrative charges on which plaintiffs rely provided inadequate notice of class-wide allegations.9 See Kloos, 799 F.2d at 400 ("To be faithful to the purposes of the filing requirement, an administrative charge must allege class-wide age discrimination or claim to represent a class in order to serve as the basis for an ADEA class action...."). The district court found that this circuit would adopt the majority rule, but accepted defendant's argument that the single-filing rule offered plaintiffs no refuge here because the underlying charges contained no allegations of class-wide discrimination.

Defendant's final argument for summary judgment was that the claims of all of the plaintiffs were time-barred for failure to file their complaint within 90 days of receiving notice from the EEOC of termination of its proceedings, as required by the ADEA.10 The EEOC proceedings on plaintiffs' charges terminated at various dates between July 21, 1993, and January 4, 1995. This action was filed on October 6, 1995, long after the 90-day period had expired for all plaintiffs.

Plaintiffs concede they all missed the 90-day deadline for filing their complaint, but seek shelter in the statute of limitations tolling rule announced in American Pipe & Const. Co. v. Utah, 414 U.S. 538, 94 S. Ct. 756, 38 L. Ed. 2d 713 (1974), and reiterated in Crown, Cork & Seal Co. v. Parker, 462 U.S. 345, 103 S. Ct. 2392, 76 L. Ed. 2d 628 (1983). Those cases held that "the commencement of a class action suspends the applicable statute of limitations as to all asserted members of the class who would have been parties had the suit been permitted to continue as a class action." American Pipe, 414 U.S. at 554, 94 S.Ct. at 766. Plaintiffs argue that the filing of the Dionne and Halligan actions suspended the running of the statute of limitations for plaintiffs, who would have been members of the Dionne and Halligan classes had class certification been granted in those cases. The district court accepted the application of the American Pipe tolling rule, but rejected plaintiffs' argument that the rule saved their claims in this case.

Assuming arguendo that the American Pipe and Crown, Cork tolling rules apply to ADEA actions, we nevertheless find that plaintiffs' claims are time-barred. We do not reach the merits of the res judicata or single-filing rule arguments.

In American Pipe the Supreme Court balanced the policies served by the class action rule, Fed.R.Civ.P. 23, and the policies served by the statute of limitations. The case arose under the Sherman Antitrust Act, and was brought as a putative class action. After the district court denied class certification, several would-be class members moved to intervene. Although the applicable statute of limitations had run as to the intervenors, the Supreme Court held that their claims were not time-barred because the filing of the putative class action tolled the statute of limitations as to all alleged class members until the district court denied certification, "at least where class action status has been denied solely because of failure to demonstrate that the class is so numerous that joinder of all members is impracticable." Id. at 552-53, 94 S.Ct. at 766 (internal quotation marks omitted).

In Crown, Cork, a Title VII case, the Court reaffirmed the American Pipe tolling rule and extended it to apply not only to plaintiffs who seek to intervene in the pending action, but also to would-be class members who file actions of their own. See id. at 349-50, 103 S.Ct. at 2395-96. The Court also did not limit its holding to instances when the class certification was denied solely on numerosity grounds.

A logical initial question is whether the Crown, Cork rule for Title VII cases also applies to ADEA cases. Defendant argues that these tolling rules do not apply to ADEA plaintiffs. This argument is grounded in the fact that both American Pipe (a Sherman Act case) and Crown, Cork (a Title VII case) arose in the context of class actions brought under Fed.R.Civ.P. 23. Rule 23 provides that all members of a class are included in the action and are bound by the judgment unless they "opt out" of the action by affirmatively requesting exclusion. The ADEA, in contrast, adopts the enforcement procedures of the Fair Labor Standards Act, see 29 U.S.C. §§ 201-219, which provides for an "opt in" procedure for class actions, requiring individuals to affirmatively file consent to the action in order to be a member of the class. See 29 U.S.C. §§ 216(b), 626(b). Defendant contends that the difference between these two procedures results from different policy considerations, and that the rationale behind the American Pipe and Crown, Cork tolling rules does not apply in the context of "opt in" class actions.

The courts of appeals that have addressed this issue have split on the outcome. Compare Sperling v. Hoffmann-La Roche, Inc., 24 F.3d 463, 471-72 (3rd Cir.1994) (opt-in plaintiff may join ADEA action after limitations period for that individual plaintiff has run if the representative plaintiffs' actions are timely) with Grayson, 79 F.3d at 1106 (opt-in ADEA plaintiffs must meet the statute of limitations and may not rely on filing of class action complaint) and O'Connell v. Champion Int'l Corp., 812 F.2d 393, 394 (8th Cir.1987) (same). We consider this an issue of some complexity, and we do not reach or resolve it here. Even assuming that the American Pipe and Crown, Cork tolling rules do apply to ADEA actions, we find that the rules do not save plaintiffs' claims. This is because plaintiffs' claims depend on the "stacking" of two sequential class actions to keep their claims from being untimely. We do not believe the tolling rules were meant to permit the stacking of class actions.

In Crown, Cork, the Court stated that "[o]nce the statute of limitations has been tolled, it remains tolled for all members of the putative class until class certification is denied," at which point "class members may choose to file their own suits or to intervene as plaintiffs in the pending action." 462 U.S. at 354, 103 S.Ct. at 2398. In this case, the first class action relevant is the Dionne action. The Dionne action was filed as a putative class action on April 20, 1993, and the district court denied class certification on July 6, 1994. Plaintiffs here were within the class sought in Dionne. Applying American Pipe and Crown, Cork would toll the running of the 90-day limitations period for each plaintiff from April 20, 1993, until July 6, 1994. At that point, each plaintiff would have had at most 90 days to move to intervene in that action or to file an individual action. But plaintiffs did not do that. The complaint in this action was filed on October 6, 1995, more than 90 days after the denial of class certification in Dionne.

Plaintiffs argue that they are saved by the filing of the Halligan putative class action. Halligan was filed in November of 1993, after Dionne was filed but before the court had denied class certification in Dionne. Halligan remained pending as an asserted but not certified class action, plaintiffs not yet having moved for class certification, on the day the instant action was filed. Plaintiffs claim that because "at all relevant times there was at least one class-action suit pending against Ground Round, and each of the plaintiffs was a member of the defined classes in those cases[, t]hose actions tolled the statute of limitations." We disagree.

The Halligan complaint alleged the same class and the same claims as did the Dionne complaint. In fact, the named plaintiff, David Halligan, was active in the effort to attain class certification in the Dionne action. Halligan submitted an affidavit in support of the Dionne motion to certify a class, in which he alleged age discrimination by Ground Round.

The policies--respect for Rule 23 and considerations of judicial economy--which animated the Crown, Cork and American Pipe tolling rules dictate that the tolling rules, if adopted at all in ADEA cases, not permit plaintiffs to stretch out limitations periods by bringing successive class actions.

Plaintiffs may not stack one class action on top of another and continue to toll the statute of limitations indefinitely. Permitting such tactics would allow lawyers to file successive putative class actions with the hope of attracting more potential plaintiffs and perpetually tolling the statute of limitations as to all such potential litigants, regardless of how many times a court declines to certify the class. This simply cannot be what the American Pipe rule was intended to allow, and we decline to embrace such an extension of that rule. At least one of our sister circuits agrees. See Salazar-Calderon v. Presidio Valley Farmers Ass'n, 765 F.2d 1334, 1351 (5th Cir.1985) ("Plaintiffs have no authority for their contention that putative class members may piggyback one class action onto another and thus toll the statute of limitations indefinitely, nor have we found any."). On closely related issues, each court of appeals to address the question has reasoned similarly and rejected efforts by late plaintiffs to resuscitate their claims through stacking of subsequent class actions. See Andrews v. Orr, 851 F.2d 146, 149 (6th Cir.1988) (class action tolls statute of limitations only for subsequent individual actions, not for subsequent class action alleging similar class and similar claims); Robbin v. Fluor Corp., 835 F.2d 213, 214 (9th Cir.1987) (same); Korwek v. Hunt, 827 F.2d 874, 879 (2d Cir.1987) (same).

The dangers which Justice Blackmun warned against in his concurring opinion in American Pipe are vividly demonstrated by plaintiffs' theory. Justice Blackmun wrote separately to stress that the Court's decision "must not be regarded as encouragement to lawyers in a case of this kind to frame their pleadings as a class action, intentionally, to attract and save members of the purported class who have slept on their rights." 414 U.S. at 561, 94 S.Ct. at 770 (Blackmun, J. concurring). This point was emphasized by Justice O'Connor in her Crown, Cork concurrence, in which she stated that "[t]he tolling rule of American Pipe is a generous one, inviting abuse." 462 U.S. at 354, 103 S. Ct. at 2398 (O'Connor, J., concurring). Rational policy considerations led the Congress to impose a statute of limitations on the bringing of ADEA actions. After class certification has been denied in an action, potential individual plaintiffs cannot extend that limitations period by relying on successive class actions which allege the same class and the same claims. Plaintiffs' claims are therefore time-barred, and the district court properly entered summary judgment in Ground Round's favor.

Affirmed. Costs to defendant.
