Within the study and practice of transitional justice, the roles played by the arts in addressing past human rights violations have become increasingly well accepted. This article examines the role of the arts in Cambodia’s transitional justice process, from the initial coupling of attempts to revive the arts with the pursuit of human rights in the early 1980s to the reparations orders provided by the Extraordinary Chambers in the Courts of Cambodia (ECCC). It identifies five main contributions the arts may make to transitional justice processes—evidence, complementary justice, outreach, activism, and critique—and demonstrates not only that various art forms have assumed each of these roles in Cambodia but also that this case extends the place of the arts in transitional justice. In particular, by highlighting the role played by local activists in seeking to revive the arts in the aftermath of the Khmer Rouge period, this article reveals the significance of arts initiatives, instigated in the absence of a formal justice process, for formal processes once they eventually emerge. In doing so, it argues that without the arts initiatives and activism that preceded it, the formal inclusion of the arts in the ECCC process would not have been possible.
