Meet Majid Khan.

The first of the so-called high value Guantánamo detainees to have seen a lawyer claims he was subjected to “state-sanctioned torture” while in secret C.I.A. prisons, and he has asked for a court order barring the government from destroying evidence of his treatment.

The request, in a filing by his lawyers, was made on Nov. 29, before officials from the Central Intelligence Agency acknowledged that the agency had destroyed videotapes of interrogations of two Qaeda operatives that current and former officials said included the use of harsh techniques.

An intelligence official denies that Khan was videotaped.

Mr. Dixon, one of Mr. Khan’s lawyers, said Saturday that the admission that officials had destroyed videotapes of interrogations showed why such an order was needed.

“They are no longer entitled to a presumption that the government has acted lawfully or in good faith,” Mr. Dixon said.
