Experience

Representative matters

Valli v. Avis Budget Grp. Inc., 162 F.4th 396 (3d Cir. 2025). In case of first impression regarding waiver of arbitral rights, obtained unanimous reversal of waiver finding in putative class action, with court holding that a motion to compel arbitration filed prior to class certification – where no class representatives are subject to arbitration agreements – does not waive arbitral rights.
In re Dravo LLC-Derivative Claims, 357 A.3d 104 (Pa. 2026). In case of first impression addressing piercing the veil of a corporate parent based on its dissolution of a subsidiary, secured unanimous reversal and ruling from Supreme Court of Pennsylvania that where statutory dissolution extinguishes the liabilities of subsidiary, there is no basis to impose the subsidiary’s liability on the parent through veil piercing.
Cnty. of San Bernardino v. Ins. Co. of Pa., 174 F.4th 597 (9th Cir. 2026). In environmental property damage insurance coverage matter, obtained unanimous reversal for county policyholder of lower court ruling that legacy policies imposed aggregate limits on property damage coverage, opening up more than $80 million of additional potential coverage.
