GAPS IN THE LEGAL REGIME OF INTERSTATE COOPERATION IN PROSECUTING CRIMES In addition, the Commission noted that the so called “Hague formula” (the obligation to extradite or prosecute, as formulated in Article 7 of the 1970 Hague Convention for the Suppression of Unlawful Seizure of Aircraft and as subsequently interpreted) served as a model for the most contemporary conventions containing the obligation to extradite or prosecute (such as the UN Convention against Torture of 1984 or the International Convention for the Protection of all Persons from Enforced Disappearance of 2006) and recommended that States consider the Hague formula in undertaking to close any above mentioned gaps in the existing conventional regime governing the obligation to extradite or prosecute. 32 Similar conclusions form the basis of the Draft Code of Crimes against the Peace and Security of Mankind, adopted by the International Law Commission at its forty-eighth session in 1996, 33 which provides for the obligation to establish the jurisdiction and the obligation to extradite or prosecute with regard to, i.a. , the crime of genocide, crimes against humanity and war crimes. Possible adoption of a convention on cooperation in the prosecution of crimes under international law, which would include the obligation to extradite or prosecute based on the “Hague formula”, could also represent a significant contribution to the clarification of the regime of universal jurisdiction. The International Court of Justice, in its judgment of 2012 in the dispute between Belgium and Senegal, 34 intepreted the system of the Convention against Torture, based on the “Hague formula”, as follows: All the other States parties to the Convention have a common interest in compliance with the Convention by the State in whose territory the alleged offender is present; this common interest implies that the obligations in question are owed by any State party to all the other States parties to the Convention. Thus, the Convention, according to the Court, gives rise to the obligations erga omnes partes and the common interest entitles each State party – regardless of whether the applicant state has any special interest in bringing the claim due to a connection with the crime, alleged torturer or his victims – to make a claim for the cessation of an alleged breach by any other State party of the obligations contained in the Convention, including (as was the case in the dispute between Belgium and Senegal) the obligations to immediately make a preliminary inquiry into the facts as soon as a suspected offender is identified in the territory of the State party and to submit the case to its competent authorities (if it does not extradite him). 35 Therefore, a possible future convention on interstate cooperation of International Criminal Justice, 10 (2012), p. 1294, fn. 90; Claus Kreß, Universal Jurisdiction over International Crimes and the Institut de Droit International, Journal of International Criminal Justice, 4 (2006), p. 584. 32 ILC, Report on the work of its sixty-sixth session (2014), doc.
