The course will have as object of the analysis of the legal discipline of international commercial transactions. The course will give particular attention to the various methods of governing international trade and related sources, including commercial practices and usages, self-regulation codes, internal, international and European rules, uniform material discipline and international private and procedural law. The course will therefore analyze the sources of state, interstate and astatual origin, their coordination, the actors of international trade and their interactions, international contracts and the rules that govern the identification of their discipline (substantial or through conflict rules). Furthermore, the methods for resolving transnational commercial disputes will be explored, both when they are held before internal judges (with particular regard to the relevant European discipline) and when such disputes, as frequently happens, are resolved through international arbitration.
