»Saarland Financial Constitutions in Times of Upheaval. Saarland Financial Constitutional Law from 1945 to 1957/1959«: Based on the economic affiliation of the Saarland to France after World War II to July 5, 1959, the thesis analyzes the financial constitutional law in the Saarland during this period. Special attention is paid to the turnover tax and the excise duties, which were largely »Frenchified« in the Saarland and distributed between the Saarland and France according to a population-based key. Furthermore, the paper highlights the parallels of this Franco-Saarland economic union to European integration.
