Filling an Accountability Gap? How a Standing UN Investigative Mechanism Would Further International Criminal Justice

Tuesday 6 December 2022
Turfmarkt 99
2511 DP The Hague

With the establishment of the International, Impartial and Independent Investigative Mechanism for Syria (IIIM), the Independent Investigative Mechanism for Myanmar (IIMM), and the UN Investigative Team To Promote Accountability for Crimes Committed by ISIL/Daesh (UNITAD) among others, the UN has taken new steps to investigate international crimes, identify atrocity structures and preserve evidence to support the work of existing accountability systems, including the International Criminal Court (ICC) and regional and national jurisdictions. This panel will discuss the prospects and potential benefits of the creation of a new standing, independent investigative mechanism in the UN system, including options for its establishment, competences, and functioning.

This panel will bring to together distinguished experts to examine the prospects and added value of a standing UN investigative mechanism. Panelists will discuss inter alia:

  • Lessons and innovations of the existing investigative mechanisms, and their broader contribution to the exercise of universal jurisdiction and accountability.   
  • The benefits and potential challenges of a standing UN investigative mechanisms, including its relationship to other justice mechanisms (e.g., ICC, domestic jurisdictions) and its benefits for victims.
  • Existing proposals for the creation of a standing UN investigative mechanism and their reception.
