Constitutional Identity, Ireland and the EU
Costello v. Government of Ireland and others is one of the most significant recent Irish Supreme Court rulings concerning EU law. The case involved a member of parliament seeking to restrain the Irish government from ratifying the 2014 EU-Canada Comprehensive Economic and Trade Agreement (CETA) on grounds of alleged unconstitutionality. Costello’s most long-lasting impact is likely to be its introduction of the concept of constitutional identity into Irish constitutional jurisprudence.
