Euro As Legal Tender (and Banknotes)
The provisions governing the euro as ‘European Single Currency’ are at the core of the Treaty on the Functioning of the European Union’s (TFEU) rules on the Economic Monetary Union (EMU). Since the euro has replaced the former national currencies of the participating Member States and is to substitute the national currencies of any future members of the euro area, it was mandatory to ascribe to the euro the status of exclusive ‘legal tender’ as per Article 128(1) TFEU. This status of the euro seems to be so evident as to be self-explanatory–but only at first glance since the concept of ‘legal tender’ and its implications in European Union (EU) and national private and public law are less clear. A satisfactory concept of legal tender is hard to define and hardly ever given on the EU level–resulting in a striking lack of legal certainty in a great variety of aspects of public and private law.
