This publication addresses the issue of mapping the justice sector and some key related institutions and is intended to assist United Nations field staff in understanding how the justice sector actually worked in the State prior to and during the conflict, and how it should function if the rule of law is to take root. It provides an overview of the key institutions, related entities or mechanisms, and identifies priorities such as the linkages between core institutions and the utility of oversight bodies. The principles used in these tools have been primarily garnered from previous experience and lessons learned in United Nations field presences.
