Supreme Court Rejects Appeal Over 9/11 Plea Deals

 

Supreme Court Declines to Review Pentagon Decision to Cancel 9/11 Plea Deals

WASHINGTON — The U.S. Supreme Court on October 19, 2026, declined to review a lower court decision upholding the Pentagon's cancellation of plea agreements involving three men accused of plotting the September 11, 2001, terrorist attacks.

The agreements involved Khalid Sheikh Mohammed, who is accused of being the principal architect of the attacks, and two alleged accomplices, Walid bin Attash and Mustafa al-Hawsawi. The proposed deals would have allowed the defendants to plead guilty in exchange for the removal of the death penalty as a possible punishment.

Why the Plea Agreements Were Cancelled

The agreements were reached in 2024 through the military commission process at Guantanamo Bay, Cuba. However, then-Defense Secretary Lloyd Austin subsequently revoked them, arguing that the decision required his authority because of the significance of the cases.

The cancellation triggered a lengthy legal dispute over whether the defense secretary had the authority to withdraw agreements that had already been approved by the official overseeing the military commissions.

A federal appeals court ruled in July 2025 that Austin had legal authority to withdraw from the agreements. Defense attorneys challenged that ruling, arguing that the cancellation violated military law and prolonged a prosecution that has been pending for decades.

What the Supreme Court Decision Means

By declining to hear the appeal, the Supreme Court left the lower court ruling in place. The decision means the defendants cannot rely on the challenged plea agreements to resolve the cases under the terms that would have excluded capital punishment.

The ruling does not itself impose a death sentence or determine the defendants' guilt. The allegations remain subject to the military justice process, and the prosecution must proceed through the applicable legal proceedings.

Trial Expected in 2028

According to Reuters, a military judge has scheduled the trial of Mohammed and his co-defendants for June 2028. The case has faced repeated delays involving legal challenges, questions about evidence and disputes over the military commission system.

The September 11 attacks killed nearly 3,000 people in the United States. The prosecution of the alleged planners has remained unresolved for more than two decades, making the case one of the longest-running terrorism proceedings in American history.

The Supreme Court's latest action marks another significant development in the legal battle over how the defendants should be prosecuted and whether the death penalty may remain an option.
