Pattiann McAdams v. Mercedes-Benz USA LLC et al., Case No. 2018-1667
Tenth District Court of Appeals (Franklin County)

ISSUES:
- Did a state court improperly readjudicate a federal court's decision in a class-action lawsuit?
- Should Ohio adopt the approach in the jurisdictions requiring compliance with court-mandated opt-out procedures and reject the state appeals court's decision that a separate, preexisting lawsuit serves as an informal opt-out of a class action?
