This paper aims at evaluating how Brazil and Uruguay have adopted different positions concerning the tension between the obligation to revealing and convicting public agents involved with massive human rights violations during former military dictatorships - which was determined by the rulings of the Inter-American Court of Human Rights (IACHR) to these countries - and domestic legislation that guarantees impunity. The author intends to assess whether and how decision-makers involved with the implementation or blocking of Transitional Justice's normative expectations in those countries issued recommendations and rulings of the Inter-American System of Human Rights. Particularly, the author will analyze: 1) in Uruguay, the creation of a law that revoked, in 2011, the Law of Expiry, and, in Brazil, in the same year, the creation of a Truth Commission; 2) the arguments deployed by the Supreme Courts of both countries complying with or repealing decisions of the IACHR.
