»The Joint Committee in the Constitutional System of Separation of Powers. A Classification of the Special Constitutional Body in the Constitutional Dogmatics of the Separation of Powers under Article 20 para. 2 sentence 2 GG«: The thesis deals with the 48-member Joint Committee, which replaces the Bundestag and Bundesrat in the defense case, and with the question of whether it satisfies the constitutional requirements of the separation of powers. In this sense, the work develops a standard of separation of powers and creates an understanding of the tensions between separation and intertwining of powers and between control and effectiveness, in which the Joint Committee acts as a compromise solution.
