Bradbury authored an additional memo dated July 2007, seeking to reconcile the interrogation techniques with new developments, including intervening legislation such as the Military Commissions Act of 2006 and the December 2005 Detainee Treatment Act. In response to this and other new legislation, the 2007 memo provided legal authorization and OLC approval for a more limited set of actions for use when interrogating high-value detainees. This approval encompassed six listed techniques, including temporary food deprivation of no less than per day, sleep deprivation by being forced to hold a "standing position for as many as four days", and several types of physical striking.
