NEW ORLEANS (AP) -- Transocean Deepwater Drilling Corp. has lost a round in its fight to avoid handing over documents to a government board investigating the 2010 Deepwater Horizon explosion.
Transocean is appealing a federal court order enforcing a subpoena of the documents by the U.S. Chemical Safety and Hazard Investigation Board.
The 5th Circuit Court of Appeals on Tuesday refused to stay the document handover while the appeal is pending.
The documents were collected by a Transocean internal investigation team.
