The matter involved overlapping PAGA and class action claims against a multi-location dealership group, with a tentative global settlement from a prior case, arbitration rulings from a separate six-hour evidentiary hearing, and competing class definitions across the related actions. The class certification opposition required synthesizing the procedural history across all related matters, identifying inconsistencies between the plaintiff's proposed class definition and the evidence adduced at the evidentiary hearing, and demonstrating that individualized issues — particularly around the commissioned-employee exemption, which required workweek-by-workweek verification — predominated over common questions. The prior attorneys' draft had been in progress for weeks. The final submission integrated the multi-case procedural analysis, the evidentiary hearing record, and the substantive predominance arguments into a cohesive opposition.
