• Rensel v. Centra Tech, Inc., 2 F.4th 1359 (11th Cir. 2021) (Successfully argued before the Eleventh Circuit Court of Appeals, securing a significant victory when the Panel vacated the district court’s order denying plaintiffs’ motion for class certification upon finding that both of the court’s alternative grounds for denying the motion were abuses of discretion.  The Eleventh Circuit’s opinion: (i) established the standard of review for trial courts considering the timeliness of a motion for class certification; (ii) reaffirmed that plaintiffs should typically be permitted discovery prior to moving for class certification; (iii) made clear that a district court’s failure to enter a scheduling order violated both the Federal Rules of Civil Procedure and the Local Rules for the Southern District of Florida; and (iv) further rejected the heightened ascertainability requirement for obtaining class certification adopted by other Circuits, including the Third Circuit.).
• Campbell v. Vilsack, EEOC No. 570-2018-00277X(Represented, on a pro bono basis, a class of deaf and hard of hearing employees of the United States Department of Agriculture (USDA) working in the metropolitan Washington, D.C. area in a disability discrimination action challenging inconsistent, unreliable, and increasingly scrutinized access to sign language interpreting services, co-counseling with the civil rights association the National Association of the Deaf.  Following eight years of litigation, the parties reached a settlement pursuant to which all USDA deaf and hard of hearing employees in the Washington, D.C. region are now able to access sign language interpreting services through a centralized system.).
