The Trias Politica Revisited

Research Question

What is the impact of court decisions on the behaviour and organization of political parties? To what extent have the courts been politicized? How does the background of judges influence their decision-making?

Project Description

While it is generally assumed that in democratic systems a structural separation of powers exists between the several branches of the state, political parties and the courts have become much more closely intertwined in recent decades. My project focuses on the changing relationship between political parties and the judiciary in post-war European democracies. It examines the judicialization of party politics by investigating the impact of court decisions on the activities and organizational structures of political parties, as well as the politicization of the judiciary by investigating the nature of partisan influences on judicial appointments. It furthermore aims to arrive at a model of judicial decision-making by analyzing the influence of the judges’ partisan background and their personal preferences and attitudes on their decisions relating to political parties.
