This standard work on prosecuting abroad considers all aspects of conducting cases abroad. Since the previous edition’s publication, the number of Member States of the European Union has more than doubled. The scope of application of European civil procedure law has thus been extensively extended. On their way to creating a unified European area of justice, the Community has enacted many new regulations in the field of civil procedure law. Many States have reformed their civil procedure law with new civil procedure regulations. In the field of international arbitration, diligent legislative work has led to a number of new laws on arbitration proceedings that are in many cases directly based on the UNCITRAL model law. This is leading to the standardization of international law, which is being experienced in the field of arbitration like no other field of civil procedure. This new edition also takes into account the great increase in literature and legislation on the problems of international prosecution. The first section of the presentation has not been conceptually changed but merely brought up to date by taking into consideration changes in the law, new literature, and more current legislation. However, the second section of this edition has a completely new concept. The previous overview, which was only able to touch on the legal state of affairs in various countries that are of significance to Germany based on economic interactions, has been replaced by a review of international civil procedure based on important legal sources and introductory literature from the EU, EEA, and the Lugano Convention as well as other significant non-European regulations. An overview of the validity of international treaties pertaining to civil procedure aims to enable the swift pinpointing of international regulations applicable to individual countries.
