In a book published in 2003 Manfred Nowak wrote: “The OAS [Organization of American States] in comparison [with the Council of Europe] is composed of a wide range of states including both the richest industrialized countries (United States and Canada) and the poorest countries of the world (e.g. Haiti), as well as democracies and military dictatorships that covered a good part of the entire hemisphere in the 1970s. Consequently, the human rights bodies of the OAS have always had to deal with far more than Europe’s ‘luxury problems’, such as the excessive duration of legal proceedings in Italy. Historically, and presently, OAS human rights bodies are challenged by widespread poverty, systematic torture and assassination of political dissidents, enforced disappearances and much more.”
It is impossible to draw a distinction like that from the Court’s case-law of the year 2009. The Court found 269 violations of Article 2 and 3 plus 145 violations of those articles because of lack of effective investigations. This makes it 1/6 of all the violations the Court found that year.
