The ELI-Unidroit Model European Rules of Civil Procedure were adopted by the European Law Institute and Unidroit in 2020. It consists of a set of main principles and rules covering a wide array of topics in the area of European civil procedure. It contains 245 rules in twelve parts, dedicated to general provisions, rules on parties, case management, commencement of proceedings, proceedings preparatory to a final hearing, access to information and evidence, judgment, res iudicata and lis pendens, means of review, provisional and protective measures, collective proceedings and costs.
Aiming at transforming the ALI-Unidroit Principles on Transnational Civil Procedure (2004) to make them suitable for the European regional context, the groundwork was laid at an exploratory workshop in Vienna in October 2013. The project kicked off in 2014, when the first three working groups were established. In the following years, five more working groups dedicated to specific topics were added, and in 2016, the Structure group was tasked with coordinating the work of the different working groups, filling the gaps, and securing a coherent set of model rules to be used by European and national legislators in particular. In collaboration with a task force charged with the (overview of) the translation of the Rules into French, the work was completed in 2020. It was approved by the ELI Council on 15 July and by ELI Membership on 5 August, and approved by the Unidroit Governing Council on 24 September 2020. This project, involving some 45 academics and practitioners participating in the working groups as well as a Steering group, advisory members from all over the world, and European and international institutions as observers, is the most encompassing set of model rules on European Civil Procedure.
