European Union – Workers. The Court of Justice of the European Union ruled that a general exclusion of nationals of other member states from access to the post of president of an Italian port authority constituted discrimination on grounds of nationality prohibited by art 45(1) to (3) of the Treaty on the Functioning of the European Union (TFEU). It followed that, in circumstances such as those at issue in the main proceedings, art 45(4) TFEU should be interpreted as not authorising a member state to reserve to its nationals the exercise of the duties of president of a port authority.
