Judge Barbier ruled in the first phase of the case that BP had committed gross negligence and that "its employees took risks that led to the largest environmental disaster in U.S. history." He apportioned fault at 67% for BP, 30% for Transocean and 3% for Halliburton. Barbier ruled that BP was "reckless" and had acted with "conscious disregard of known risks."[183][184]
