One of the most fundamental obstacles to EU constitutionalization is said to be the lack of a European demos, which is seen as a precondition for any constitutional system.The term ‘demos’ originally referred to the common people of an ancient Greek state. Today, demos can describe the populace of a democracy, as a political unit. European Member State courts, such as the GFCC, have raised prominent concerns that further constitutionalization is constrained by the absence, in Europe, of a common attachment as an entity; they emphasize that there is no ‘European people’ and no future possibility thereof, meaning that the final say in constitutional matters will always rest with each European Member State.
