Penn State International Law Review


This comment begins by discussing the ineffectiveness of ex post facto measures in controlling terrorism. It then describes the preventive - or "pre-attack" - measures which nations and their air carriers should take in order to secure aircraft prior to departure. In this respect, the annexes amending the Convention on International Civil Aviation will be emphasized insofar as they relate to aviation security precautions. Finally, the comment focuses upon the methods by which states can enforce the provisions of the annexes against one another.
