California Supreme Court adopts GMSR’s client’s arguments in widely followed case, clarifying the law regarding both arbitrations and attorney ethical duties

A large law firm, Sheppard Mullin, had for many years provided advice to a client on an as-needed basis. Sheppard then undertook the defense of a new client, J-M, in a suit brought by the longtime client. Sheppard never disclosed the conflict to either client. Instead, Sheppard told J-M that the firm ‘may currently or in the future’ represent parties adverse to J-M. J-M then signed a blanket waiver of all such conflicts. An arbitration panel held that Sheppard Mullin was entitled to collect its fees for representation of J-M. The California Supreme Court concluded that Sheppard’s failure to disclose the conflict made the waiver invalid and violative of public policy, requiring vacation of the arbitration award.

Today, the California Supreme Court sided with GMSR’s client, J-M, in a landmark case that impacts arbitration law, attorney ethics, and the practice of law in California.
