40 Of course, no common good exists a priori under the conditions of a fragmented global society. But the autonomous regimes can build on the fictitious assumption of common reference points and formulate a common good in the specific terms and norms of each regime.

70 The definition of the crime of aggression and its ‘trigger mechanism’ were adopted by consensus at the first Review Conference in Kampala in 2010 and cannot enter into force before 2017; ICC Res. RC/Res.6 of 11 June 2010.

71 The Security Council has extended this concept to non-international armed conflicts, acknowledging their possible cross-border effects, threatening the stability of the region, e.g., The Situation in Darfur (Sudan), UN Doc. S/RES/1564 (2004).

72 Since the 1990s, this power has included the authority to create international criminal tribunals such as the ICTY. See, Prosecutor v. Tadić, Decision on the Defence Motion for Interlocutory Appeal on Jurisdiction, Case No. IT-94–1-AR72, 2 October 1995, paras. 30–9.

104 Such a practice existed already in the form of Status of Forces Agreements (SOFAs) between the sending state and the UN or the UN and the mission state. This practice, mainly used by the US, is incorporated in Art. 98(2) of the RS, which relieves member states of the obligation to extradite in contravention of international agreements, however, this does not affect the ICC's jurisdiction. See Jain, supra note 96, at 245; Condorelli and Ciampi, supra note 75, at 598; Happold, M., ‘Darfur, the Security Council, and the International Criminal Court’, (2006) 55 ICLQ 226CrossRefGoogle Scholar, at 235 (on Res. 1593).

117 A study conducted by an African Expert Group argued that the concerns of the African States should be taken seriously, but to also consider that Sudan had not been making serious efforts for a domestic prosecution, and that the peace process was essentially stagnating. This suggests a reverse instrumentalization of Art. 16, and a concurrent danger of de-legalizing the ICC system. D. Akande, M. du Plessis and C. C. Jalloh, ‘Position Paper.

144 Condorelli and Ciampi, supra note 75, at 507; see also, Ciampi, supra note 107, at 891. Condorelli and Ciampi argue that, if the Security Council referred the situation to the ICC – as in the Darfur case – there needs to be a change in circumstances to warrant subsequent deferral.
