The European Law Institute informs us that the ELI-UNIDROIT Model European Rules of Civil Procedure were approved by the ELI bodies on 15 July and 5 August 2020. The UNIDROIT Governing Council will vote upon the Model European Rules of Civil Procedure soon at its meeting on 23–25 September 2020.
If adopted as well there, the ELI/UNIDROIT Rules may contribute harmonising the national procedural rules of the EU Member States and as such broaden the basis for mutual trust in the Member States’ judicial cooperation in civil matters. The Rules may be taken as a kind of minimum standard or best practice, as the case may be in the respective issue in question, and the more a national rule of civil procedure deviates from these standards, the more justifications and explanations are invited, if not expected (see e.g. Matthias Weller, in Matthias Weller/Christoph Althammer, Mindeststandards im europäischen Zivilprozessrecht – Grundvoraussetzung für gegenseitiges Vertrauen, Mohr Siebeck, Tübingen 2015, Vorwort, p. VI, comparing this mechanism to some extent with the control of standard terms).
