According to emails obtained by ABC News, military commissions set to try Guantanamo detainees are "rigged, fraudulent, and thin on evidence," Al Jazeera reported.
The emails were sent by two former prosecutors to supervisors in the Office of Military Commissions in March 2004 - three months before Australian detainee David Hicks was charged.
The first mail, from prosecutor Major Robert Preston to his supervisor, said the process is perpetrating a fraud on the American people, and that the cases being pursued are marginal.
"I consider the insistence on pressing ahead with cases that would be marginal even if properly prepared to be a severe threat to the reputation of the military justice system and even a fraud on the American people," Maj Preston wrote.
