Riforme elettorali e partiti politici europei

This essay aims to analyse how electoral system for European elections, and the discussion about their constitutional significance and reform, have contributed to shaping the legal status of the European political parties. The relationship between electoral laws, party systems and political party regulation is a locus classicus of constitutional law. In this respect, the peculiar character of the composite constitutional system of the European Union, in which supranational and national legal materials coexist, shows that the development of the European political parties and its autonomisation from national party systems is still an ongoing process
