The More Favourable Provision Clause in EU Migration Law: Expanding Fundamental Rights through National Discretion?

Interaction between different levels of fundamental rights protection is a widely debated topic in EU scholarship, which has long dealt with situations in which national legislation lowered legal standards in the EU. Less explored, however, is the opposite case: when Member State regulations set standards higher than those enshrined at EU level. This can occur through application of the more favourable provision (MFP) clause – commonly enshrined in EU directives dealing with (but not limited to) immigration and asylum. Under it, Member States can apply more favourable standards insofar as they comply with EU legislation. Though seldom discussed in existing literature, the MFP clause is a critical issue of EU migration law and illustrative of challenges facing the EU constitutional order, for it highlights the relationship between fundamental rights protection in the multi-layered EU system and general principles of EU law. Against this backdrop, this paper will investigate the features of the MFP clause in EU migration law and analyse the CJEU’s adjudication in immigration and asylum cases, exploring its reasoning in testing application of MFP clause against EU law.
