But the summary in the Volokh Conspiracy blog states: "Ninth Circuit Panel Applies and Upholds the Federal Statute Preempting Various Lawsuits Against Gun Manufacturers, in Ileto v. Glock, Inc. (just handed down today)...{T]he opinion was by Judge Graber joined by Judge Reinhardt, with a partial concurrence and partial dissent by Judge Berzon."
