MEMORANDUM AND ORDER
ERIC F. MELGREN UNITED STATES DISTRICT JUDGE
This matter comes before the Court on Plaintiffs’ Motion for Order (Doc. 442). Plaintiffs’ motion seeks a determination regarding (1) whether the single-file rule excuses former consent plaintiffs from individually exhausting administrative remedies; and (2) whether an ADEA collective action tolls the deadlines for a consent plaintiff to file an administrative charge or lawsuit. Plaintiffs also request that the Court equitably toll this limitations period for ninety days following the resolution of this motion. For the reasons stated herein, the Court finds that Plaintiffs’ limitation period was tolled only while class claims were pending, that the single-filing rule is unavailable to Plaintiffs, and that Plaintiffs are not entitled to equitable tolling.
I. Factual and Procedural Background
This complex and multi-faceted case began when The Boeing Company sold its assets and operations in Wichita, Kansas, and related locations to the newly-formed Spirit AeroSystems, and Spirit hired some but not all of the employees who had worked at Boeing. The excluded, or non-hired, Boeing employees filed numerous claims against Boeing and Spirit. The named plaintiffs brought numerous claims for class-wide relief under the collective action provisions of the Age Discrimination in Employment Act (“ADEA”), based on pattern-and-practice and disparate-impact theories of liability. The Court conditionally certified those claims, and nearly 700 plaintiffs opted in. In 2010, however, the Court granted summary judgment on plaintiffs’ ADEA claims.
As a result of the Court’s prior orders in this case, only one claim remains – individual claims of disparate treatment based on age in violation of ADEA. Because of its resolution of these claims on the merits, the Court did not directly address Defendants’ motion to decertify the collective action. The Court certified its rulings as final, concluding that the adjudicated claims were separate and distinct from the remaining individual disparate-treatment ADEA claims that the named class representatives brought on their behalves. Counsel for these plaintiffs now seeks judicial guidance regarding the application of the single-file rule and the statute of limitations to these remaining plaintiffs, whose individual claims turn on facts unique to each.
A. Plaintiffs’ Limitations Periods to File an Administrative Charge or a Subsequent Lawsuit Were Only Suspended During the Pendency of their Class Claims.
It is well-established that ADEA plaintiffs must first exhaust administrative remedies by filing a charge within 300 days of the alleged discriminatory conduct. This 300-day period begins to run when the plaintiff first receives notice of an adverse employment action. Any subsequent civil action asserted by an individual must be filed at least sixty days after filing the administrative charge, but within ninety days after receiving notice of dismissal or termination of the charge from the EEOC. If a plaintiff fails to observe these requirements, the claims are barred.
Under the Supreme Court’s decision in American Pipe & Construction v. Utah,  these filing periods are subject to tolling for individual plaintiffs who timely file a class action. The tolling doctrine under American Pipe was established to preserve judicial economy in class actions. Because this policy is no longer relevant when a court denies class certification, the Supreme Court held in American Pipe that such tolling ceases when a court issues an order decertifying a class.
Here, the parties appear to agree that the individual Plaintiffs’ filing periods were tolled during the pendency of the class action in this case. Plaintiffs argue that the tolling period remains in effect because the Court never formally entered an order decertifying the class, but instead shattered the class by granting summary judgment on all class claims. Defendants, however, suggest that the tolling period expired when the Court granted summary judgment on all class claims.
While American Pipe held that the tolling period expires upon decertification, its progeny focus less on decertification specifically, and instead emphasize the point in time when tolling no longer serves the purposes of class treatment under Rule 23. Several cases from across the country have held that the tolling period expires upon a district court order that (1) denies class certification or decertifies a class; (2) excludes an individual plaintiff from a certified class; or (3) grants summary judgment on all class claims.
The District Court for the Eastern District of North Carolina addressed this very issue in Womack v. United Parcel Service, Inc. In Womack, like here, the district court granted summary judgment on class claims. The defendant argued that tolling of individual filing deadlines ended upon summary judgment, while plaintiffs argued that tolling extended until the class was decertified or final judgment was entered. The court in Womack first recognized that “the principal concern motivating the creation of the tolling doctrine was the preservation of the primary goals of Rule 23, maintaining efficiency and economy in class actions.” The court thoroughly reviewed cases across the country, acknowledging that “[m]any Circuit Courts of Appeals have held that tolling ceases directly upon the denial of class certification, and does not extend through some later order in the action or throughout the appeals process.” The Womack court held that tolling ceased upon summary judgment because such an order effectively resolves all class claims upon which class members could have based a tolling argument.
The Court is persuaded by Womack and other cases that emphasize the true heart of the tolling doctrine under American Pipe: judicial efficiency achieved through class treatment under Rule 23. Like the plaintiffs in Womack, the individual consent plaintiffs in this case could no longer reasonably rely upon the class action to obtain relief when the Court entered summary judgment on class claims. The filing limitations period recommences once it is no longer reasonable for plaintiffs to rely on the class to protect their rights. Because the purposes for tolling under American Pipe no longer ...
