Ambiguities in Articles 5(2), 121 and 123 of the Rome Statute‪.‬

There is a fundamental ambiguity in the Rome Statute's requirements dealing with entry into force of the provision on aggression that is necessary for the Court to exercise jurisdiction over the crime of aggression. On one interpretation of Article 121, the provision (or provisions) will apply to all States Parties once seven-eighths of them have accepted the provision. One another interpretation, the provisions will apply only to those States (no matter how few) that specifically agree to it. The author examines the relevant language of the Statute, the less-than-conclusive preparatory work, and the political considerations that might lead to some kind of compromise or "fix" in time for the Review Conference in 2010.
