Competing Visions and Constitutional Limits of Schengen Reform: Securitization, Gradual Supranationalization and the Undoing of Schengen as an Identity-Creating Project

Schengen integration has been home to different visions from the outset. In this vein, it owes much of its success to the fact that it has been both practical and symbolic in nature. However, this equilibrium of different visions has been upset following a series of crises. By prioritizing security considerations over alternative visions of Schengen, some Member States have reintroduced internal border controls on a quasi-permanent basis. Current reform proposals seek to address this situation but may be unable to revive the co-existence of the different visions underpinning the earlier phases of Schengen integration. Rather, as this investigation suggests, the reform that is currently being discussed would reaffirm the nature of Schengen integration as a pan-European security project. While this goes hand-in-hand with elements of supranational governance and coordination, it may impair the role of Schengen as an identity-creating project. This investigation analyzes the elements of the reforms discussed, presents them in the light of different visions of Schengen, and draws attention to possible constitutional limits of its reform.
