HOUSTON (AP) - Prosecutors and the owner of the rig that exploded and led to the massive 2010 Gulf oil spill were to argue in court over whether the company should honor subpoenas from a federal board investigating the accident.
A federal judge in Houston was set on Wednesday to hear the arguments, part of a civil complaint filed last year.
Federal prosecutors allege Transocean Ltd. has not fully complied with five subpoenas the U.S. Chemical Safety Board has issued.
The board is one of several agencies investigating the April 20, 2010, explosion.
Transocean says the safety board does not have jurisdiction in the probe.
The blast killed 11 workers and led to more than 200 million gallons of oil being released from BP's undersea well.
