About Us

PEJ, a 501(c)(3) charitable organization, was founded in 2016 by Cynthia Tai, a former prosecutor in the U.S., and at the International Criminal Court in The Hague. With an increase in mass atrocities worldwide, PEJ believes now more than ever that there is an overwhelming need to empower local populations seeking justice. By partnering with local organizations, we train local lawyers and investigators to have the skills necessary to collect and preserve evidence in a manner that meets international legal standards.

PEJ applies a novel, victim-centered approach to addressing mass atrocities. We only engage in cases where requested to do so by the survivors, their families, or local community members and where we have the appropriate expertise. Before engaging in any case, we evaluate the situation to identify the best possible chance of success. We believe that professional, impartial, and prompt investigation contributes to holding perpetrators of atrocities accountable, reducing risks for survivors and witnesses, ending cycles of violence, creating more accountability mechanisms, deterring future perpetrators from committing atrocities, and giving victims a sense of justice.


Together, PEJ’s staff and Board have decades of experience in international legal matters. Working in partnership with local organizations, we bring evidence of atrocities to the forefront in legal arenas.
