Occasional Practice


Since leaving the practice of international criminal justice in 2007, I have engaged in occasional practical work to contribute and keep my scholarship connected to the field.


Senior Legal Advisor (Part-time), Extraordinary Chambers in the Courts of Cambodia

In November 2014, I accepted a part-time role as a Senior Legal Advisor to the Judges of the Supreme Court Chamber at the Extraordinary Chambers in the Courts of Cambodia (ECCC). In this role, I provide legal advice to judges on issues within my core areas of expertise for upcoming appeals. The ECCC is charged with prosecuting those most responsible for crimes committed by the Khmer Rouge in Cambodia between 1975 and 1979.

Member, Independent Commission of Experts on Commerce, Crime and Human Rights

I recently accepted an invitation to sit on an Independent Commission of Experts on Commerce, Crime and Human Rights created by the International Corporate Accountability Roundtable (ICAR) (see here). The Independent Commission of Experts, which is comprised of a group of senior jurists and criminal law experts that includes a retired Supreme Court Justice and former senior member of the International Criminal Court, will develop a framework to govern State practice in addressing challenges to prosecuting corporate crimes. The commission will conclude by September 2015.

Training War Crimes Prosecutors

I have trained prosecutors on the law governing the responsibility of commercial actors (corporations and businesspeople) for international crimes. In 2010, I organized a training of prosecutors from twelve national systems, including the United States, Belgium, Canada and others, together with the Open Society Justice Initiative. This training was held at the International Criminal Court, with the joint support of the Dutch and Canadian War Crimes Units. In 2013, I presented on these issues to prosecutors of international crimes from all European states through the European Union’s justice wing, Eurojust.
