This chapter profiles legal activity during 2015 in the context of cases involving crimes under international conventions. In recent decades, criminal investigations and prosecutions for conflict-related violations have increased. Cases have been pursued in international institutional venues such as ad hoc war crimes tribunals, hybrid courts and the International Criminal Court (ICC), as well as by ordinary and specialized national courts, some domestic and others in foreign countries. Recognizing the infeasibility of trying in national courts all those suspected of having participated in the genocide, the Rwandan government established the gacaca system of local tribunals in 2000. The chapter provides a list of countries where legal activity occurred in 2015 to pursue or undertake prosecutions of non-nationals for violations committed outside the territory of the national prosecuting authority and involving victims who are not nationals of that country. The countries are Argentina, Belgium, Chile, Finland, France, Germany, Netherlands, Norway, Senegal, South Africa, Spain, Sweden, Switzerland, United Kingdom and United States.
