In October 2011, in an operation called the "baseline review," the prison seized all legal materials belonging to "high-value detainees," starting with Abd al-Rahim al-Nashiri. The prison also announced that it would change its previous policy and begin reviewing legal mail for its content. In response, the Chief Defense Counsel (United States) ordered the attorneys under his supervision to stop sending privileged communications to Guantanamo prisoners. Under the Chief Defense Counsel (United States) policy, Al-Baluchi could not receive mail from his attorneys until November 2013.
