Subsidiarity as a Subject of Battle in European Union Politics (2020)

in: Oxford Research Encyclopedia of Politics

Abstract

Since the Maastricht Treaty (1993), subsidiarity has guided the political process surrounding the distribution of competences between administrative layers in the European Union (EU). The EU's subsidiarity regime affects the politics and governance of the EU, because the notion of subsidiarity allows for continuous negotiation over its practical use. The constant battle over subsidiarity implies that the notion changes its meaning over time and alters the power relations between different actors within the EU. Since the Lisbon Treaty (2009), subsidiarity has mainly strengthened the position of member states at the expense of the Commission.
