Moussaoui wants guilty plea voided

Lawyers urged Zacarias Moussaoui not to plead guilty to terrorism charges. They just couldn’t tell him why.

In newly filed court documents, Moussaoui argues that court-imposed secrecy undermined his ability to present an adequate defense. His new lawyers say Moussaoui’s guilty plea should be thrown out and a new trial should be convened for the man who once claimed to have been a part of the Sept. 11, 2001, terrorist plot.

Moussaoui was not allowed to see the classified evidence against him and was shut out from closed-door hearings in which that evidence was laid out.

His lawyers could advise him, but they could not discuss everything -- only the evidence approved by prosecutors or the judge.

Defense lawyers say they were barred from discussing with Moussaoui even evidence that could help prove his innocence. They say Moussaoui faced an unconstitutional choice: plead guilty or go to trial without knowing the evidence.
