The Margin of Appreciation in the Inter-American Human Rights System and its Use by the Supreme Court of Argentina

Operators of international systems for the protection of human rights have not only supported the consideration of international treaties as paradigmatic documents in the labour of constitutional adjudication by national operators, but also sponsored an hermeneutic canon, remarking the importance of taking these instruments within the context of current life.
In this context, the margin of appreciation doctrine is winning an important space in the Inter-American jurisprudence as well as it´s became a central topic in academic dossiers of Latin American countries.
This paper proposes to inquire if this doctrine, as it is in the heart of some of the most important international human rights decisions, may affect the universality of human rights. Or, on the contrary, if this margin prevents courts from imposing unhelpful uniformity, wich may also affect the states´s sovereignty and even human rights itselves.
