The International Congress of Comparative Law, organised by the International Academy of Comparative Law, took place in Vienna from 20th to 26th July 2014. A number of different legal topics were discussed, such as: comparative law and unification of laws, legal education, private international law, environmental law, intellectual property, labour law, public international law, tax law and constitutional law. The reports written by the national commentators on their various fields are based on the questionnaires set out by the general reporting secretaries, who are experts in their own fields. Most of the German reports are published in this book.
