Abstract: This Article analyses the issue of the compatibility with the ne bis in idem principle of the double-track sanctioning systems present in various European legal orders in the light of the case-law of the European Court of Human Rights and the Court of Justice of the European Union. In particular, after a reconstruction of the most significant case-law after the famous ruling A and B v. Norway, three main critical points are brought into focus: the divergences between the national and European case-law on the interpretation of the notion of idem factum, the difficult practical application of the close connection test between proceedings developed by the European Court of Human Rights, which can be seen as the precipitate of an unsatisfactory balancing act of opposing interests, and the possible extension of the ne bis in idem principle also to cases of lis pendens.

Keywords: ne bis in idem – double-track enforcement systems – proportionality – tax – market abuse – lis pendens.
