Journal for providing generous and insightful feedback on the article during the review process and to participants at the 'Futures, Challenges and Transformations for Transitional Justice' workshop at the University of Minnesota Law School in 2016 for their comments on an earlier version. Recent work on transitional justice (TJ) has exposed the difficulties both of establishing agreement over what TJ is and of evaluating its effects. 1 This article contributes to scholarship on evaluating TJ by showing how differences in understandings of the nature and value of 'justice' in TJ affect the focus of scholarly research and interpretation of its results. TJ is understood here to be a series of (usually legalized) political practices, in line with others who recognize TJ as something more than simply a legal project. 2 Judgements of the successes, failures and impacts of TJ are part of this political practiceassessments affect the kinds of TJ programmes which will be implemented in future.

The evaluation of evaluation (with 'evaluation' interpreted broadly heresee below) matters not just for academic reasons but also because TJ is increasingly commonplace. 4 Transitional mechanisms have been mooted for all current conflicts and recent postconflict states, and TJ attracts a high level of donor funding and nongovernmental organization (NGO) support. Indeed, Makau Mutua claims that 'in many circles, transitional justice has become an article of faith as a catalyst for reclaiming societies in political and social imbalance and dysfunction.' 5 There is considerable demand from practitioners for policy advice on which TJ mechanisms should be funded and how they should be designed, and scholars have a responsibility to ensure that advice given is justified by the
