Europa im Parteienwettstreit in den Ausschüssen des Bundesrates

The party politicisation of European integration in the German Bundesrat remains largely in the dark due to the missing documentation of the federal states’ voting behaviour in the plenary sessions. For an empirically informed analysis, this contribution draws on a novel dataset that focuses on the Bun- desrat committees where individual votes are registered. The findings reveal that there have been pro- found partisan considerations of federal states’ governments in European affairs since the early 1990s, being almost as strongly pronounced as in similar decision-making procedures related to domestic legislation.
