"Is Moussaoui entitled to any remedy?"
Justice Department lawyer Paul Clement said Moussaoui has the right to material that might exonerate him but national security overrides his right of access to enemy combatants held abroad. The government fears the witnesses might reveal secret information.
"The proper question is, `Does the Constitution require them [terrorism defendants] to get a windfall' " because Al Qaeda operatives were captured? he asked. The answer must be no, Clement said.
Frank Dunham Jr., the federal public defender representing Moussaoui, said the remedy lay in the sanctions imposed by a trial judge that led to the government's appeal. US District Judge Leonie Brinkema, in Alexandria, Va., banned any evidence connecting Moussaoui to the Sept. 11, 2001, attacks and barred prosecutors from seeking the death penalty.
"Our system of American justice and fair play will not permit" the government to seek Moussaoui's execution while denying him favorable testimony, Dunham said.
While Moussaoui is the only US defendant charged with terrorism related to the attacks, Dunham said that even "for a most notorious enemy charged with the worst crime in American history, we will not bend the rules for our convenience even at the expense of our security."
"This is America and in the end, this is more about who we are than it is about Mr. Moussaoui."
Moussaoui was charged in December 2001 with participating in a broad Al Qaeda conspiracy to commit terrorism and hijack airplanes. The overt acts included, but were not limited to, planning the Sept. 11 attacks.
He was not present at the hearing. His venomous court filings recently caused the trial judge to revoke his right to represent himself in his case.
Brinkema's ruling followed a refusal by the government to obey two orders directing it to make three Al Qaeda witnesses available to the defense. If the government can't win a reversal, it may decide to move the case to a military court. The witnesses reportedly include top operatives Ramzi Binalshibh and Khalid Shaikh Mohammed.
