Argentina put its dictators on trial after the 1976-1983 reign of state terror. Now courts are investigating the role of prominent corporations in the kidnapping, torture and disappearance of their workers. The debate over how to tackle corporate involvement in human rights violations is intensifying worldwide....Argentina’s experience in seeking justice for crimes committed during its 1976-1983 dictatorship serves as an important reference...In 1986 and 1987, Argentina’s Congress passed amnesty laws that blocked the prosecution of many crimes against humanity committed during military rule. The laws were eventually repealed and declared unconstitutional—in 2003 and 2005, respectively—and hundreds of dictatorship-era cases were brought or reopened. The Center for Legal and Social Studies (CELS) has broadened its efforts to seek accountability on the issue of corporate complicity in crimes against humanity, aiding prosecution efforts through a three-pronged strategy of litigation, research and advocacy.
