This paper relates to the examination of Article 3 of the European Convention of Human Rights.
The norm was investigated taking into account the case law of the European Court of Human Rights, which gave an evolutionary interpretation of it through its hermeneutic activity, allowing the text to become a pillar in the protection of prisoners' rights. The thesis consists of three chapters. The first one concerns the origin of the authorities promoters of human rights at the European level, such as the Council of Europe, the European Court of Human Rights and the Committee for the Prevention against Torture. This analysis also focuses on the most significant judgments expressed by the Court, through which the Strasbourg court has developed Article 3. Finally, the last chapter is dedicated to the detention conditions of prisoners in European prisons, investigating the problem of overcrowding and the solution represented by the pilot judgment, also focusing on the relationship between the European Court of Human Rights and the Committee for the prevention against torture.
