This is a most interesting decision from the point of what constitutes an "open trial", "the right to face your accusers", "the right to cross examine witnesses", "right to present evidence in your own defense".
It is indeed difficult to balance the various interests in this case, the rights of the accused and the national security concern. But I guess I won't be able to read the whole decision. You can only read it at the courthouse. That too is extremely unusual.
A non-American enemy combatant discovered on our soil in the midst of planning an act of war against our country.... I don't see why he should be allowed to "appeal" squat.
