“„Under the new rules, each detainee will be assigned a U.S. military official, not a lawyer, to represent his interests and examine evidence against him. In proceedings before a board composed of military officers, detainees will have the right to call witnesses and present evidence when it is “reasonably available,” the official said. The boards will determine whether detainees should be held by the United States, turned over to Afghan authorities or released. For those ordered held longer, the process will be repeated at six-month intervals.
