The United States Court of Appeals for the 5th Circuit in New Orleans, Louisiana this week refused to grant Transocean Deepwater Drilling, Inc., owner of the Deepwater Horizon, a stay of a recent federal district court order that the company promptly turn over documents that the U.S. Chemical Safety Board (CSB) has subpoenaed from the company for its investigation into the April 2010 explosion at the Macondo drilling facility in the Gulf of Mexico.
