This news was in the CSB’s 2015 budget request. It said:

Deepwater Horizon – The CSB’s investigation into the Deepwater Horizon/Macondo accident of April 2010 continues, and the CSB has achieved significant legal victories during FY 2013. In April 2013 a federal judge in Houston upheld the CSB’s jurisdiction to conduct the investigation, and overruled the rig operator Transocean in its effort to block the release of information to the CSB. On July 23, 2013, the United States Court of Appeals for the Fifth Circuit in New Orleans, Louisiana, ruled in favor of the CSB and refused to stay the lower court’s decision. As a result of this ruling, the CSB has gained access to vital documents and information subpoenaed throughout the course of the agency’s investigation. Access to these documents will allow the CSB to evaluate factors that no other agency has investigated in detail, such as the role of human and organizational factors in this catastrophic accident.

The CSB’s investigation findings will be published in three separate volumes. The first two volumes are scheduled to be released in the spring of 2014, and the third volume will be released in the summer of 2014.”
