International legal scholarship to date has largely neglected the donor-driven dynamics of international criminal justice. This article advances what I term ‘donors’ justice’ as an analytic frame for interpreting the work of international criminal tribunals. Donors’ justice is defined as third-party financial support for tribunal activity. It imports market rationalities into the field of criminal accountability, which assume overlapping discursive, political, and economic forms. The Special Court for Sierra Leone provides a case study of the implications of donor-driven logics for international criminal justice, particularly the material problems of insecure funding and the ethical problems of limited personal jurisdiction.
