International Seminar on “Effects of Judgments” in Honour of Professor Piet Taelman

(23-10-2025) On Thursday 2 October 2025, the Institute for Procedural Law hosted an international seminar on “Effects of Judgments” to mark the retirement of Professor Piet Taelman.

Judgments do not merely bring cases to an end, they also set the stage for remedies, enforcement, and further legal debate. Far from being uniform, judgments take different forms, raising important questions about res judicata, enforceability, and cross-border recognition and enforcement.

Chaired by Wannes Vandenbussche and Bart Krans, the seminar featured a range of contributions, each exploring a distinct aspect of the legal operation or enforcement of judicial decisions:

  • Benoit Allemeersch (KU Leuven): The Extension of the Positive Effect of Res Judicata to Third Parties under Belgian Law: une fausse bonne idée?
  • Beatrix Vanlerberghe (University of Antwerp): The Effect of Judgments vis-à-vis Third Parties
  • Burkhard Hess (University of Vienna): The Implementation of Directive (EU) 1828/2020 in Austria and Germany
  • Wannes Vandenbussche and Niels Depaepe (Ghent University): The Effects of Final Decisions within the Framework of Directive (EU) 1828/2020
  • Wolfgang Hau (Ludwig Maximilians-University Munich): Unified European Rules on the Recognition and Enforceability of Third-Country Judgments
  • Laura Ervo (University of Helsinki): Moral and Economic Costs of Enforcement
  • Viktória Harsági (Pázmány Péter Catholic University): History of Releasing Res Judicata in Hungarian Civil Procedure in the Recent Decades – Extraordinary Remedies
  • Aleš Galič (University of Ljubljana): The Effects of a Criminal Judgment on a Civil Case
  • Bart Krans and Alain Ancery (Leiden University): The Impact of EU Law on Res Judicata

Most of the papers have been published in open access in a special issue of Ghent University’s Law & Criminology Journal: Law & Criminology Journal | Issue: Issue: 2(2) Effects of Judgments – Special Issue in Honour of Piet Taelman (2025).
