A judge has refused to dismiss a lawsuit alleging that Indiana's Bureau of Motor Vehicles overcharged motorists by tens of millions of dollars. A Marion County judge yesterday (Monday) turned down a request from the BMV for dismissal of the lawsuit. The judge, instead, ordered both sides to resume mediation within 30 days. The BMV's request at a hearing last month followed an independent audit that concluded the agency might have overcharged motorists more than the $60 million it has previously disclosed. The lawsuit filed in 2013 seeks to force the BMV to return millions of dollars from overcharging for vehicle registrations and other services.
