The course treats what can be called the general part of transnational contract law, i.e. the general principles of law which are of relevance in any kind of international contract, be it sale, construction, shipping, financing, or joint venture. At present, such contracts are governed either by uniform rules of international conventions or by the national laws applicable by virtue of conflict of law rules. The course puts the existing national and international solutions in a comparative perspective so as to work with the sources of such generally accepted principles. Where there are divergences between existing solutions, the course focuses on the elaboration of new efficient solutions that are internationally acceptable and have the potential of becoming general principles in the future. For these purposes, special attention is given to the UNIDROIT Principles on International Commercial Contracts and the European Principles of Contract Law.
