`(e) Affirmative Defenses- It shall be an affirmative defense to a violation of this section that--

`(f) Limitation on Collateral Attack on Underlying Deportation Order- In a criminal proceeding under this section, an alien may not challenge the validity of the deportation order described in subsection (a) or subsection (c) unless the alien demonstrates that--

`(1) the alien exhausted any administrative remedies that may have been available to seek relief against the order;

`(2) the deportation proceedings at which the order was issued improperly deprived the alien of the opportunity for judicial review; and

`(3) the entry of the order was fundamentally unfair.

Such alien shall be subject to such other penalties relating to the reentry of removed aliens as may be available under this section or any other provision of law.
