Supranational

At a supranational level, countries have adopted a range of treaty and convention obligations to relate the right of individual litigants to invoke the jurisdiction of national courts and to enforce the judgments obtained. For example, the member nations of the EEC signed the Brussels Convention in 1968 and, subject to amendments as new nations joined, it represents the default law for all twenty-seven Member States of what is now termed the European Union on the relationships between the courts in the different countries. In addition, the Lugano Convention (1988) binds the European Union and the European Free Trade Association.
