This book analyses the objectives underlying the establishment of the Assembly of States Parties to the Rome Statute (ASP) and those underlying its governance role towards the International Criminal Court (ICC). Arguing that the governance exercised by the ASP must in view of these objectives remain facilitative in nature, this book then sets out a standard of good governance based on eight principles: participation; consensus-orientation; the rule of law; accountability; transparency; responsiveness; efficiency and effectiveness; and representation and gender-sensitivity. This is done with a view to ensure that the ICC is both accountable as well as independent in its functions.
