The AP (3/21, Kunzelman, 335K) reports from New Orleans, “A federal judge conducting a trial to assign fault for the nation's worst offshore oil spill dismissed claims Wednesday against a BP contractor and the company that made a key safety device on the drilling rig that exploded in the Gulf of Mexico, triggering the disaster.” The AP continues, “After plaintiffs' attorneys rested their case Wednesday, U.S. District Judge Carl Barbier ruled there was no evidence that BP's drilling fluids contractor M-I LLC made any decision that led to the blowout of BP's Macondo well. Barbier dismissed all claims against M-I on the 15th day of the trial. The judge also agreed to rule out punitive damages against Cameron International, the manufacturer of the blowout preventer on the ill-fated Deepwater Horizon rig, which was rocked by an explosion and fire in 2010 that killed 11 workers and touched off the enormous spill. 'I have not heard or seen evidence that would in any way support a finding of gross negligence or willful misconduct on the part of Cameron,' Barbier said.”
