The Supreme Court today upheld a June 2014 district court ruling that BP and Anadarko are liable for civil penalties related to the 2010 Gulf of Mexico oil spill. BP could be on the hook for $13.7 billion in Clean Water Act penalties, while Anadarko could be forced to pay more than $1 billion. The two companies were co-owners of the Macondo well, which spewed more than 3 million barrels of oil into the gulf after an explosion aboard the Deepwater Horizon drilling rig.
Via Reuters, BP and Anadarko argued they should not be held responsible for the oil spill since Transocean owned the rig.
