This article assesses the African Union’s (AU) concerns about Article 16 of the Rome Statute of the International Criminal Court (ICC). It seeks to articulate a clearer picture of the law and politics of deferrals within the context of the AU’s repeated calls to the United Nations Security Council (UNSC, or the Council) to invoke Article 16 to suspend the processes initiated by the ICC against President Omar Al Bashir of Sudan. The UNSC’s failure to accede to the AU request led African States to formally withhold cooperation from the ICC in respect to the arrest and surrender of the Sudanese leader. Given the AU’s continued concerns, and the current impasse, fundamental questions have arisen about the Council’s authority to exercise, or not exercise, its deferral power. This culminated into a November 2009 African proposal for an amendment to the Rome Statute to empower the UN General Assembly to act should the UNSC fail to act on a deferral request after six months. Although ICC States Parties have so far shown limited public support for the AU’s proposed amendment to the deferral provision, this article examines its merits because a failure to engage the “Article 16 problem” could impact international accountability efforts in the Sudan, and further damage the ICC’s credibility in Africa. This unresolved issue also has wider significance given that the matters underlying the tension – how ICC prosecutions may be reconciled with peacemaking initiatives and the role and power of the Council in ICC business – will likely arise in future situations from around the world
