Liberal peacebuilding has been touted as the solution to intra-state conflict in the post-Cold War era, as many believe liberal democratic states are less likely to engage in conflict and are more likely to respect human rights. Security sector reform involves criminal justice reform that is designed to establish respect for human rights, democracy, and the rule of law in post-conflict environments (PCEs). This paper explores PCE criminal justice reform through a case study of corrections reform in Kosovo. Fourteen Canadian participants described the dynamics and challenges they faced while conducting corrections reform activities abroad, and spoke about the appropriateness of using UN and Western-developed frameworks in Kosovo and other PCEs. This paper presents the main findings that emerged from the data, highlights policy and practice implications for those engaged in PCE corrections reform activities, and identifies key areas for future research activities, recommended in light of the weaknesses identified in the current study.
