Changing balances of PIL theories in a Europeanized Private International Law

This article offers a reading of the case law of the Court of Justice of the European Union (CJEU) from a private international law perspective (PIL). The developments that the CJEU thus gave start to in the field of company law, and especially in EU citizenship, invites for a reshaping of the balances between Union law and Member State private international laws, especially in the field of methods of application. This article aims to shed light into the question ‘To what extent has the EU citizenship as a connecting factor in the context of a Europeanized PIL changed the PIL traditional methods of application?’ The host Member State is obliged to recognize the duly created rights in the original Member State, with respect to the mutual recognition principle. The return of the vested rights theory as opposed to the use of the traditional conflict-of-law approach seems on its way.
