The U.S. Supreme Court rejected two appeals from Volkswagen AG, leaving intact rulings that let state and local governments sue over a diesel-emissions cheating scandal that already has cost the German automaker more than $23 billion.
The justices without comment on Nov. 15 refused to hear arguments by Volkswagen and several company units that the U.S. Clean Air Act provides a broad shield for automakers from state and local liability over updates to vehicle emissions systems.
