Amicus curiae brief of the National Association of Criminal Defense Lawyers in support of appellant Lt. Cmdr. Matthew M. Diaz.
Argument: Lt. Cmdr. Diaz, a Navy JAG convicted of improper disclosure of classified information did not receive a fair trial because he was precluded from introducing any evidence of his “intent,” “state of mind,” “motive,” “ethical obligations” as an attorney, and “ethical obligations” as a commissioned officer in the Navy. Appellant was precluded from introducing evidence that the information (a list of detainees being held at Guantanamo Bay, Cuba) was not marked as classified; that he did not know or believe his actions to be illegal; and that his actions were in good faith and consistent with his duties and obligations a lawyer. Excluding this evidence violated his right to a fair trial and right to present a defense. Furthermore, the Military Judge failed to determine whether the “classified information in question was lawfully classified."
