A US appeals court recently rejected a plea deal for Khalid Sheikh Mohammed, the alleged mastermind behind the 9/11 terrorist attacks.
This agreement would have spared Mohammed and his co-defendants the death penalty, instead sentencing them to life imprisonment without parole.
The 2-1 decision, announced on Friday, followed years of negotiations and legal challenges concerning the admissibility of evidence obtained through torture.
Families of 9/11 victims were divided on the deal, some preferring a trial to ensure accountability and uncover more information.
