Salman Rabeii is probably a brother of the late Fawaz al-Rabeiee alias Furqan al-Tajiki, to whom he sent a letter while in Afghanistan.
Initially the Bush administration asserted that they could withhold all the protections of the Geneva Conventions to captives from the war on terror. This policy was challenged before the Judicial branch. Critics argued that the USA could not evade its obligation to conduct a competent tribunals to determine whether captives are, or are not, entitled to the protections of prisoner of war status.
Subsequently the Department of Defense instituted the Combatant Status Review Tribunals. The Tribunals, however, were not authorized to determine whether the captives were lawful combatants -- rather they were merely empowered to make a recommendation as to whether the captive had previously been correctly determined to match the Bush administration's definition of an enemy combatant.
Rabeii chose to participate in his Combatant Status Review Tribunal. Rabeii didn't attend his Tribunal in person. But he dictated responses to the allegations for his Personal Representative to read to the Tribunal.
The allegations against Rabeii were:
Rabeii told his Personal Representative he was not associated with al Qaeda. He acknowledged he was in Afghanistan, in August, but he denied that he attended the al Farouq training camp.
Rabeii denied he was captured with other. He told his Personal Representative that he voluntarily sought out Afghani authorities in Jalalabad, and surrendered himself, because he wanted help getting back to Yemen
Rabeii totally denied that he had ever threatened the USA.
In the Combatant Status Review Tribunals it is the Recorder's responsibility to act like a Prosecutor, and compile and distribute the allegations against the detainee. The Tribunal members were concerned that the wording of the allegations, as read out, differed from the wording in copies they had been given to read.
Detainees who were determined to have been properly classified as "enemy combatants" were scheduled to have their dossier reviewed at annual Administrative Review Board hearings. The Administrative Review Boards weren't authorized to review whether a detainee qualified for POW status, and they weren't authorized to review whether a detainee should have been classified as an "enemy combatant".
They were authorized to consider whether a detainee should continue to be detained by the United States, because they continued to pose a threat -- or whether they could safely be repatriated to the custody of their home country, or whether they could be set free.
The factors for and against continuing to detain Rabeil were among the 121 that the Department of Defense released on March 3 2006.
