Plaintiffs who have sued General Motors Co. over defects in their cars, including disbarred civil rights attorney Stephen Yagman, are continuing to fight a federal panel’s decision to transfer their lawsuits to a coordinated proceeding in New York.

GM, facing an onslaught of lawsuits since recalling 2.6 million vehicles over ignition switch defects, has moved to transfer all the cases to U.S. District Judge Jesse Furman of the Southern District of New York. So far, the U.S. Judicial Council on Multidistrict Litigation has sent 101 cases to Furman for pretrial purposes.
