Following the 4 research aims, the JUDI-ARCH project was divided into 4 interrelated work packages (WPs), which focused on conceptual (WP1), qualitative socio-legal (WP2), quantitative (WP3) and theoretical issues (WP4).
WP 1 created a novel conceptualization of JSG, and resulted in a special issue of the German Law Journal entitled “Judicial Self-Government in Europe” (vol. 19, no. 7, 2018), which provided a comprehensive and up-to-date comparative account of major JSG models and issues across Europe. The special issue covered 12 national jurisdictions, which represent all existing models of judicial self-governance: a strong judicial council model (France, Italy, Romania, Slovakia), a moderate judicial council model (Spain, the Netherlands, Poland, Slovenia), a Court service model (Ireland) and a Ministry of Justice model (Germany, the Czech Republic). It also addressed 2 supranational courts and a number of crucial cross-cutting issues, such as judicial selection, the role of court presidents and a pioneering article analysing JSG at international courts. The special issue made a considerable impact in terms of readership both within the research field and in practice, being referred to in Opinions of the Advocate General of the CJEU in cases addressing the Polish constitutional crisis.
In order to systematise the scope of actors and competences conceptualised in WP1, we constructed the de jure JSG index as a main result of our WP3. The index seeks to capture the amount of power held by judges in various institutional models of JSG. Following the completion of the index, WP3 explored the effects of the institutional organization of JSG on principles of judicial independence. A set of articles published in leading journals showed that even ministerial models delegate significant powers to judges and that more decentralised regulation of JSG makes the field less susceptible to capture from outside (political interferences) or inside (judicial oligarchies).
A major innovation in our approach was the integration of comparative legal perspectives with sociological and political science approaches. On the basis of over a hundred interviews with insiders (judges, politicians and lawyers), the WP2 explored how elites in six old and new EU member states perceive the functioning, positive and negative, and how they envisage improvements in the JSG system. Combined with the overarching theoretical WP4, we analysed the different perceptions of judicial councils from the perspective of the separation of powers (Kosař et al. European Visions of Judicial Self-Governance, manuscript under review in CUP). WP4 also reacted to some of the most recent challenges to the separation of powers, such as the rise of populism and emergency governance following the Covid-19 outbreak, and provided for their better understanding by studying them through the prism of JSG and the separation of powers.
