In April 2011, ECCHR submitted an amicus curiae brief in the criminal investigation in Jujuy, Argentina, examining sugar company Ledesma's liability for human rights violations during the Argentine military dictatorship. The submission also points out that the Argentinian judiciary has a responsibility to investigate and prosecute for human rights violations committed by corporate actors during the dictatorship.
In spring of 2012, the Federal Court in Jujuy summoned the pair for questioning. On 13 March 2015, ECCHR presented a request to the Argentine Supreme Court in the Ledesma case to be incorporated in the Court’s register, with a view to potentially intervening as an amicus curiae at a later stage of the proceedings. The reason for filing this request was the 13 March 2015 decision by the Federal Criminal Cassation Chamber (Cámara Federal de la Casación Penal) in the Ledesma case, reversing the confirmation of the indictment of the two accused, Lemos and Blaquier.
