No reason was given for the cancelation.
Judge James Pohl, an Army colonel, ruled in July that no conflict of interest arose for defense attorneys from the FBI approaching a security officer for a defense team. The allegations surfaced in April, further delaying a complex, slow-moving case.
Lawyers for accused Sept. 11 mastermind Khalid Sheik Mohammed and four other suspects want Pohl to determine the extent of FBI contact with defense team members.
Mohammed and fellow Sept. 11 suspect Ramzi Binalshibh were among prisoners who underwent torture by the Central Intelligence Agency, according to the report by the Senate Intelligence Committee released on Tuesday.
The report on the CIA interrogation program implemented after the Sept. 11 attacks said Mohammed was subjected to waterboarding, or simulated drowning, “rectal hydration” and sleep deprivation.
The 2001 attacks using hijacked airliners killed almost 3,000 people in New York, Washington and Pennsylvania. The defendants face possible death penalties if convicted.
