The Texas Supreme Court on Friday rejected BP's $750 million insurance claim for the 2010 Deepwater Horizon explosion that killed 11 people and spewed millions of barrels of oil into the Gulf of Mexico.  

The high court ruled that BP's Transocean Ltd. policy does not cover BP for subsurface pollution damage that occurred following the April 20, 2010, explosion and spill from Transocean's Deepwater Horizon oil rig, 42 miles off the coast of Louisiana. BP had leased the platform and was managing the drilling at the time of the accident.

“We are disappointed and are considering our options,” Geoff Morrell, BP's senior vice president for U.S. communications and external affairs, said in an emailed statement on the ruling.

More than 3 million barrels of oil spilled into the Gulf before the Macondo well was was capped 87 days later on July 15, 2010. It is considered the worst oil spill in history. 

The case was referred to the Texas Supreme Court by the U.S. 5th Circuit Court of Appeals to determine whether the appeals court's ruling in the case conflicted with state law. An earlier ruling in the case reversed a decision that BP was entitled to the coverage.
