In Chapter Five, I begin my inquiry into possibly alternative paradigms for a re-imagining of transitional justice, with a particular focus on post-conflict peacebuilding. I explore the emergence and trajectory of the concept of post-conflict peacebuilding, from a 1991 report by UN Secretary General Boutros Boutros-Ghali, to the more recent notion of “sustaining peace.” In particular, I examine the concept of peacebuilding as a facet of liberal post-conflict governance. Together with development, human rights and transitional justice, peacebuilding has become a global project, the invocation of which often serves to prize open the door of sovereignty for liberal statebuilding interventions. I pay particular attention to the role of concepts of law and justice as they have been played through the peacebuilding prism.
