Ride-hailing firm Lyft Inc. is opposing a move by plaintiffs attorneys to coordinate more than 20 lawsuits that allege its drivers sexually assaulted passengers.

In a Los Angeles courtroom Wednesday, lawyers argued over whether to coordinate the suits as part of California’s Judicial Council Coordinated Proceedings. Lyft, represented by Beth Stewart, a partner at Williams & Connolly in Washington, D.C., called the proposed move an “improvident and unprecedented invitation” to make “San Francisco Superior Court a national clearinghouse for claims against San Francisco-based companies,” according to court documents.
