In spite of the undoubtedly great and rising importance of the international legislative co-operation regarding private international law, it must be remembered that no successful unification or harmonization of conflict rules has ever taken place on the universal level, and that the conflict rules stemming from international legislative co-operation between a limited number of countries give rise to the same problems as non-harmonized rules, whenever they have to be used in relation to countries not participating in the legislative co-operation in question. This book will therefore focus on the last-mentioned problems and refrain from dealing with the particular issues arising from international legislative co-operation in the field of private international law. One of the principal aims of Michael Bogdan is to demonstrate the relationship between the national rules of private international law and the rest of the legal system of the forum country, in the first place its substantive private law and its law of civil procedure, as well as to illustrate the impact of the forum country’s general ethical and other values on its private international law.
