The Forfeiture of Corporate Pension Entitlements, Published by Verlag Recht und Wirtschaft, Heidelberg 1970 (ISBN 3-8005-6167-0) This book is the doctoral dissertation of the author. It shows that the then common unfettered practice of forfeiture of corporate pension entitlements, when an employee leaves his employment before reaching the legal retirement age, is against the law. The question affected 60% of the Federal Republic of Germany's labour force. In 1972 the Federal Industrial Tribunal, and then in 1975 the legislature, accepted the new interpretation.

Volume 32 of the publications of the Karl-Bräuer-Institute of the German Taxpayers Federation, Wiesbaden 1975  This opinion expressed the view that the then existing privileges claimed by parliamentarians as to taxation exemptions, payments to them by lobbyists, and civil servant status benefits were unconstitutional. The German Taxpayers Federation presented the manuscript, prior to its publication, to the Federal Constitutional Court which adopted this view in decision of November 5, 1975 (BverfGE 40,296)

	Possibilities of Direct Democracy at the Local Level. Published in Jörn Ipsen (ed.), Continuity or Reform. An Analysis of Local Authority Constitutions, 1990, pages 57-86: Also published in: Die Öffentliche Verwaltung 1990, pages 85-97  This article is supplemented by several of the author's later papers. It underlines the special qualities of the constitution of local authorities in the state of Baden-Württemberg. These have three structural characteristics: the direct election of mayors, flexible election lists for the local councils with cumulative votes for candidates and the possibility of citizen initiatives and decisions. The article recommends the adoption of this model by other states. This publication directly influenced the contemporaneous reform of the Constitution of local authorities in the state of Schleswig-Holstein. In the meantime, most of the model's characteristics, especially the direct election of mayors, have been introduced, in some cases with modifications, in all other states.

	The Glitter of Democracy: Politics without Accountability - Ignoring the People, Droemer Publishing House, Munich 2000 (ISBN 3-426-27204-0) This book deals with the disintegration of accountability in German federalism and the possibilities for direct decision-making at local state, federal, and EU levels. It provides an extension and elaboration of the arguments made in the book, The Glutton as Caterer (Fetter Bauch regiert nicht gern). The German system of executive federalism, which dates back to Bismarck, is unique; it results in the disempowerment of both parliament and people and leads to political paralysis. There is no continuous public outcry and protest solely because the complicated procedures are so abstruse. The author proposes that the solution can be found  in mobilizing public awareness and establishing requisite institutions. This implies the reform of the electoral laws and the development  of initiative and referendum.
