Even though Germany and Poland are neighbours that are bound together by a joint European tradition and have much in common in their public law systems, they may fundamentally differ on certain legal issues. In comparative law, diversity is not a term of abuse. For many years, there has been a lively debate in Polish-German comparative law, above all in the field of administrative law. This book presents a selection of papers dealing with topics in administrative law and administrative sciences. These papers were presented by scholars and doctoral students from Poland and Germany at a bilateral symposium under the headline "Administrative Traditions in Poland and Germany: Similarities and Differences", which took place at the Berlin School of Economics and Law.
