Critical appraisal of the ICC Office of the Prosecutor's work

Open Society Justice Initiative (OSJI), convened a high-profile online expert workshop entitled “Improving the Operations of the ICC Office of the Prosecutor: Reappraisal of Structures, Norms, and Practices”.

The March workshop brought together a group of thirty-five (inter)national criminal justice practitioners and experts with extensive experience in investigating and prosecuting international crimes and monitoring the respective proceedings. The experts were requested to critically appraise the work of the ICC OTP in the following areas: preliminary examinations, investigations, prosecutorial strategy, outreach and engagement, completion strategies, and the OTP’s structure, ethics, and culture.

Informing the ongoing Independent Expert Review

The consultations held during the two-day workshop will inform the currently ongoing Independent Expert Review of the International Criminal Court (ICC) and the Rome Statute system as a whole. The discussions focused specifically on the third cluster of issues indicated for this expert review process as well as on related topics, including but not limited to the OTP’s organization, management, and staffing. The workshop outcome report, which highlights the main areas of concern and related recommendations, has been conveyed to the members of the ICC Independent Expert Review Panel. Such recommendations might also be of use to the next ICC Prosecutor, who will be elected at the 19th session of the ICC’s Assembly of States Parties (New York, 7-17 December 2020).

resolution establishing the Independent Expert Review (IER) and appointing nine renowned experts in the field of international criminal justice and governance of international organisations. The IER panel will critically appraise the Court’s operations in three key areas: governance, judiciary, and preliminary examinations, investigations, and prosecutions. The experts have been requested to produce “concrete, achievable, and actionable recommendations aimed at enhancing the performance, efficiency, and effectiveness of the Court and the Rome Statute system.”

The IER panel started its work in January 2020 and is at present carrying out a comprehensive critical evaluation of the Court’s operations in order to identify measures for strengthening the Court and improving its performance. The experts invited States Parties, civil society, ICC staff, and other stakeholders to submit views relevant to the issues under review. The IER is expected to submit its final report to the Bureau and the ASP in September 2020, which will then be considered by the ASP in December 2020 in order to decide on the next steps to be taken. That ASP, a new Prosecutor, six judges, and a new Bureau will also be elected.
