Hazaifa Parhat, a Uighur (pronounced weeger) was declared an “illegal enemy combatant” because the Uighur separatists are occasionally friendly with people who are friendly with al Queida, and the U.S. Court of Appeals for the District of Columbia ruled that this was insufficient in a unanimous vote.
Note that this was not under the Supreme Court’s habeas corpus ruling. It was under the “Detainee Treatment Act” that the Republithug congress passed in 2006 stripping everyone of habeas corpus rights.
There was no evidence. Not even after Bush and His Evil Minions™ declared them terrorists at the bidding of the Chinese government, and then tortured these guys on behalf of the Chinese Communists.
No evidence. And the only reason to call them “illegal enemy combatants” was because Bush wanted to make nice with the Chinese commies.
The specifics of the non-existent evidence are still not public, as the judgement has to be scrubbed of classified data, but that’s why a bunch of Republithug appointed judges.
