2 For an example, see A. Zimmermann, ‘Article 5’, in O. Triffterer (ed.), Commentary on the Rome Statute of the International Criminal Court (2008), marginal note 39: ‘Given the difficulties encountered both before and during the Rome Conference, as well as during the work of both the preparatory Commission as well as the Special Working Group on the Crime of Aggression of the Assembly of States Parties so far in reaching a generally acceptable definition of the crime of aggression and in delimiting the appropriate role of the Security Council, and further taking into account the high threshold for an amendment of the Statute, it seems to be quite unlikely that the Parties to the Statute will be able during the upcoming Review Conference to include the crime within the list of crimes for which the ICC has subject-matter jurisdiction.’ Note that the last part of this sentence is inaccurate in the light of Art. 5(1)(d) of the ICC Statute.
3 The crucial preparatory work which was done within the Special Working Group on the Crime of Aggression is most usefully documented in S. Barriga, W. Danspeckgruber, and C. Wenaweser (eds.), The Princeton Process on the Crime of Aggression: Materials of the Special Working Group on the Crime of Aggression (2003–2009) (2009), passim.
