The Pentagon chief loses bid to reject 9/11 plea deals

The military appeals court released its ruling Monday night, according to the U.S. official, who was not authorized to discuss the matter publicly and spoke on condition of anonymity.

Military prosecutors and defense attorneys for Mohammed, the accused mastermind of the attacks, and two co-defendants reached the plea agreements after two years of government-approved negotiations. The deals were announced late last summer.

Within days of news of the plea deal this summer, Austin issued a brief order saying he was nullifying them.

He cited the gravity of the 9/11 attacks in saying that as defense secretary, he should decide on any plea agreements that would spare the defendants the possibility of execution.

Defense lawyers said Austin had no legal authority to reject a decision already approved by the Guantanamo court's top authority and said the move amounted to unlawful interference in the case.

The military judge hearing the 9/11 case, Air Force Col. Matthew McCall, had agreed that Austin lacked standing to throw out the plea bargains after they were underway. That had set up the Defense Department's appeal to the military appeals court.

Austin now has the option of taking his effort to throw out the plea deals to the U.S. Court of Appeals for the District of Columbia Circuit. The Pentagon did not immediately respond to a request for comment.

Ridah bin Saleh al-Yazidi's return to Tunisia leaves 26 men at Guantanamo. That's down from a peak population of about 700 Muslim men detained abroad and brought to the prison in the years after the Sept. 11 attacks.

Al-Yazidi's repatriation leaves 14 men awaiting transfer to other countries after U.S. authorities waived any prosecution and cleared them as security risks.

The Biden administration, pressed by rights groups to free remaining Guantanamo detainees held without charge, transferred out three other men this month. The U.S. says it is searching for suitable and stable countries willing to receive the remaining 14.

Al-Yazidi is the last of a dozen Tunisian men once held at Guantanamo.

Of those remaining at Guantanamo, seven - including Mohammed and his 9/11 co-defendants - face active cases. Two others of the 26 total have been convicted and sentenced by the military commission.
