Explicit legislative characterisation of overriding mandatory provisions in EU Directives: Seeking for but struggling to achieve legal certainty

Abstract

Traditionally, the judiciary has been tasked with characterising a provision in EU secondary law as an overriding mandatory provision (“OMP”) in the sense of Art 9(1) Rome I Regulation. This paradigm has however shifted recently as the legislator has started setting out such OMP characterisation explicitly, which this paper addresses with regard to EU Directives. The analysis of two Directives on unfair trading practices in the food supply chain and on the resolution of financial institutions reveals that their explicit legislative characterisations of OMPs can benefit legal certainty if properly drafted by the EU and correctly transposed into national law by the Member States. These requirements have not yet been fully met as there are inconsistencies and confusion with only domestically mandatory provisions, which need to be resolved. More generally, the paper elucidates the tensions of competence between legislators and courts on both the EU and national levels due to the explicit legislative characterisation. It also considers the side effects on pre-existing and future provisions in Directives without explicit legislative characterisation. Finally, it acknowledges that the extraterritorial effect of OMPs is intensified and therefore requires the legislator to seek international alignment.
