ICTJ occupies an important space where it can draw together actors from the highest levels of national and international organizations as well as the most experienced civil-society voices, to compare experiences, dissect problems, and chart the course for future successes in transitional justice. Since its inception, ICTJ has been privileged to be able to call on key stakeholders and policymakers to come together in such forums. The Greentree Estate on Long Island, NY, in particular has been the location of many significant meetings hosted by ICTJ. In 2003 we convened a two-day meeting that included all of the principals of the UN agencies and departments working on transitional justice issues. This meeting directly contributed to the development of the UN Secretary General’s Report on the Rule-of-Law and Transitional Justice. In 2007, we partnered with the German Federal Government for a major event looking into the challenges of the simultaneous pursuit of peace and justice in light of the creation of the ICC. The conference led to the publication of Building a Future on Peace and Justice: Studies on Transitional Justice, Peace and Development.

From 2010-13 we hosted events at Greentree and in Stockholm that brought leading figures from the world of criminal justice to assess how the idea of complementarity and the promotion of national prosecutions could be made a success. In 2013 we partnered with the Kofi Annan Foundation to consider the role of truth-seeking efforts in peace processes. Key events resulting from this collaboration included a high-profile gathering in Greentree with core UN and other peace mediators. This was followed by a major gathering in Bogotá, Colombia, which unfolded in the midst of the Havana peace negotiations. Nearly 1,000 people attended the conference, with former UN Secretary-General Kofi Annan and Colombian President Juan Manuel Santos presenting. The event is credited with playing an important part in formulating the conversation on the future truth commission in Colombia.
