‘Since its formal introduction in the Maastricht Treaty, EU citizenship has laid claim to a constitutional status. The Union Treaties – long described by the Court of Justice as the EU’s constitutional texts – explicitly confer the status of Union citizenship on all nationals of the Member States. The asserted significance of this was subsequently confirmed in the seminal Grzelczyk judgment, in which the Court famously declared that EU citizenship was ‘destined to be the fundamental status of nationals of the Member States’.’
