In order to further the first two principles—affirming community norms and offering an inclusive design process—transitional justice mechanisms must improve their capacity to recognize and support local moral authority. Simply discerning relevant norms and the interests of the different stakeholders is no small task, and requires a multipronged strategy to optimize the chances of success. This Article suggests three approaches to discern local preferences in the process of transitional justice mechanism design: empirical studies of the perceptions of local populations, surveys of local moral traditions, and participation of local moral leaders.
