This contribution aims at analyzing the evolution of the Inter-American Court on Human Rights case law on social rights. I intend to focus my analysis in the field of environmental rights. Human Rights are the basis of any constitutional system. In this regard, the doctrine mentions the development of an Ius Constitutionale Commune. The Inter-American System has built a solid basis of protection, which is instrumental for the dialogue between judges. These standards contribute in consolidating a substantial Rule of Law, even in a process of social transformation. The Inter-American environmental developments could undertake an important role in transforming Latin-Americans societies. Increasing transparency, access to information, widening participation and access to justice are essential in the process of transforming inequality by strengthening not only Rule of Law but also democracy.
