Conference Room Paper of the Independent International Commission of Inquiry on Ukraine: On 29 August 2023, the Independent International Commission of Inquiry on Ukraine published a report in which it made recommendations on proposed accountability measures and expressed its support for the creation of a tribunal for the crime of aggression as well as efforts to amend the Rome Statute to allow for broader jurisdiction of the crime of aggression (para. 946).
It identified the need for establishing a special tribunal since “there is currently no international court with jurisdiction to undertake this necessary accountability measure” and taking into account evidence relating to acts of aggression in ICC proceedings as context of other ICC Statute crimes or as an aggravating circumstance would “not fully reflect the gravity of the crime of aggression as such, which is a separate crime, different from the three other crimes” (paras 924, 925, 946).
It assessed existing proposals for a special tribunal for the crime of aggression, namely (1) the Chatham House Proposal based on States granting jurisdiction to a dedicated tribunal as well as (2) the Yale Club Proposal and (3) the Proposal by the Ukraine Task Force of the Global Accountability Network, both based on the involvement of the UN General Assembly requesting the establishment of such a tribunal (paras 927-934).
The Commission of Inquiry made recommendations for the on-going reflection process of States, inter alia, that (1) “a certain degree of cooperation and coordination” may be advisable between the ICC and a possible special tribunal, that (2) a revision of Article 15bis of the Rome Statute to cover nationals of Non-States Parties “could limit criticism based on selectivity”, that (3) “a sufficient number of globally dispersed States should support the establishment of a special tribunal” to address legitimacy concerns and that (4) a new tribunal must be “independent, impartial and observe all fair trial rights” (paras 936-945).
