Universal Jurisdiction cases have so far mostly been prosecuted and investigated in Europe or North America, with one significant exception: Argentina. Nearly a dozen cases of international crimes committed abroad are currently before its judges and prosecutors. To support legal practitioners and civil society actors engaged in building and litigating international crimes cases based on extraterritorial and universal jurisdiction in Argentina, TRIAL International publishes a briefing paper – available in English and Spanish – which provides an overview of the country’s legal framework regarding the investigation and prosecution of international crimes, along with its practical application.
