A person charged with violating section 70503 of this title, or against whom a civil enforcement proceeding is brought under section 70508, does not have standing to raise a claim of failure to comply with international law as a basis for a defense. A claim of failure to comply with international law in the enforcement of this chapter may be made only by a foreign nation. A failure to comply with international law does not divest a court of jurisdiction and is not a defense to a proceeding under this chapter.
