Introducing the Transitional Justice Evaluation Tools (TJET) database

The TJET project offers a comprehensive database for exploring the supply of transitional justice (TJ) in every country of the world. TJET provides detailed descriptive information on domestic, foreign, and international prosecutions; truth commissions; reparations policies; vetting policies; amnesty laws and offers; and UN investigations. This article describes TJET’s quantitative dataset, consisting of longitudinal data from 1970 to 2020, with over 400 measures related to the design and operation of TJ mechanisms. Because TJ has become integral to discussions related to democracy and rule of law promotion, as well as peacebuilding, it is necessary that researchers and practitioners use the most comprehensive information possible for grounding their analysis and advocacy. The TJET dataset is unique not only in its global coverage, but also in its custom sampling feature, allowing users to select which types of cases to compare. This article provides descriptive data on TJ attributes, analysis of new trends, and an examination of the temporal relationship between different TJ mechanisms.
