It is increasingly common for countries emerging from civil war or authoritarian rule to create a truth commission to operate during the immediate post-transition period. These commissions— officially sanctioned, temporary, non-judicial investigative bodies—are granted a relatively short period for statement-taking, investigations, research and public hearings, before completing their work with a final public report. While truth commissions do not replace the need for prosecutions, they do offer some form of accounting for the past, and have thus been of particular interest in situations where prosecutions for massive crimes are impossible or unlikely— owing to either a lack of capacity of the judicial system or a de facto or de jure amnesty. As described below, the work of a truth commission may also strengthen any prosecutions that do take place in the future.
