BP appeals spill ruling that may spell $18 billion fine

BP has challenged a federal judge’s ruling that the company’s exploration unit acted with gross negligence in causing the 2010 Gulf of Mexico oil spill, a decision that exposed the UK-based energy company to as much as $18 billion in fines under US law. This is BP’s first appeal of US District Judge Carl Barbier’s September decision that the company was 67% responsible for causing the worst offshore spill in US history. The judge determined rig-owner Transocean Ltd. (RIG) was 30 percent liable and cement-services provider Halliburton 3% responsible for the disaster, which killed 11 workers.
