Duane Morris Takeaways: On October 15, 2025, in Eli Lilly & Co., et. al. v. Richards, et al., No. 25-476 (U.S. Oct. 17, 2025), Eli Lilly & Co. filed a Petition For Writ Of Certiorari after a decision by the U.S. Court of Appeals for the Seventh Circuit which created a four-way circuit split as to the proper interpretation of 29 U.S.C. ' 216(b). This petition drew briefing from several amici curiae, including the U.S. Chamber of Commerce and the CHRO Association.

Similarly, when the U.S. Court of Appeals for the Ninth Circuit decision widened that circuit split to include five different methodical approaches in Cracker Barrel Old Country Store, Inc. v. Andrew Harrington, et al., No. 25-559 (U.S. Nov. 5, 2025), Cracker Barrel also filed a Petition For A Writ of Certiorari.

Significant for readers of this blog, both petitioners and amici also cited the Duane Morris Class Action Review as the authoritative source on FLSA certification statistics and the widening circuit split regarding when it is appropriate to send notice to would-be plaintiffs, under 29 U.S.C. ' 216(b) in a Fair Labor Standards Act ("FLSA") collective action.

In its review of our practice group's resource, Employment Practices Liability Consultant Magazine ("EPLiC") said, "The Duane Morris Class Action Review is 'the Bible' on class action litigation and an essential desk reference for business executives, corporate counsel, and human resources professionals." EPLiC continued, "The review is a must-have resource for in-depth analysis of class actions in general and workplace litigation in particular.

With the submission of our analysis to the U.S. Supreme Court, we are humbled and proud to be cited as the authoritative source in the class action space.

The Briefing In Richards And Harrington

Both Cracker Barrel and Eli Lilly correctly argued in their petitions that "the circuits are split five ways in how to interpret" Section 216(b) and the case law in this area "is in total disarray." Both petitions ask the U.S. Supreme Court to help organize this "disarray." As such, a brief guide through these disjointed methodological approaches is included below.

First, there is the familiar and lenient two-step standard in Lusardi v. Xerox Corp., 118 F.R.D. 351 (D.N.J. 1987), which was expressly adopted by the U.S. Court of Appeals for the Second Circuit, Scott v. Chipotle Mexican Grill, Inc., 954 F.3d 502, 515 (2d Cir. 2020), and "acquiesced to . . . without express adoption" by the First, Third, Tenth, and Eleventh Circuits. Kwoka v. Enterprise Rent-A-Car Company of Boston, LLC, 141 F.4th 10, 22 (1st. Cir. 2025); Zavala v. Wal Mart Stores Inc., 691 F.3d 527, 534 (3d Cir. 2012); Thiessen v. Gen. Elec. Cap. Corp., 267 F.3d 1095, 1105 (10th Cir. 2001); Hipp v. Liberty Nat'l Life Ins. Co., 252 F.3d 1208, 1219 (11th Cir. 2001)

Under the Lusardi approach, at step one, a plaintiff moves for conditional certification, relying solely on his or her allegations, and not competing evidence submitted by the employer. If the employee's motion is granted, would-be plaintiffs receive notice of the lawsuit and then have the ability to opt-in as party plaintiffs to the case and participate in discovery. At the close of discovery, the employer can then move to decertify the conditionally certified collective action, and prove the employees are not similarly situated with the benefit of discovery and evidence.

Second, in Campbell v. City of Los Angeles, 903 F.3d 1090, 1114 (9th Cir. 2018),the Ninth Circuit adopted a variation of the Lusardi two-step approach but also required the plaintiff to show he or she is similarly situated to his or her fellow employees in "some material aspect of their litigation" and not just...
