Law is a polysemic concept. Every meaning of the word has a great significance to the people and to society, in order to guarantee protection of the individual and collective rights, but also to promote social peace and to guarantee coexistence and balance in an unbalanced and uneven world. A world who fights global crisis and local challenges every day. Problems that cannot escape the gaze and structure of the model of justice that can be shaped. Either if you see Law or Justice as a value (or virtue, in a philosophical sense), as a power of the State (if linked with the judiciary branch), as a structure and model (with a physical, geographical, material, personal and environmental dimension), as a principle or like ways or paths for conflict solution (procedural or non procedural nor jurisdictional -ADR/MASC-), Law is the backbone that holds a fair, equitable and peaceful society. The project is focused on the study of the meaning of Sustainable Law, not only in its national context, but also from an international outlook, and to do so accordingly to its three domains: a. Sustainable Law in its social domain, b. Sustainable Law in its economic domain, and c. Sustainable Law in its environmental domain.
