Constitutional question

I read with increasing frequency provisions inserted into various pieces of legislation that purport to prohibit review of that legislation by any court, up to and including the Supreme Court. (Such a clause, for instance, is present in the heinous Military Commissions Act of 2006.)

It would be interesting to hear from someone well-versed in Constitutional law as to whether the courts may be bound by such provisions, or whether such provisions are unconstitutional on their face and thus not binding upon the courts.
