Treaty Ratification, Investor State Arbitration, and Constitutional Identity: Implications of Costello v Government of Ireland [2022] IESC 44

TriCON Webinar - Wednesday 10 May 2023

  • Date: Wednesday, 10 May 2023
  • Time: 2 - 3pm & 3.15 - 4.30pm
  • Overview

    In Costello v Government of Ireland, the Supreme Court held that it would be unconstitutional to ratify the Comprehensive Economic and Trade Agreement between the EU and Canada (CETA) on the ground that it infringed Ireland’s juridical sovereignty. However, the Court also suggested that ratification would be constitutionally permissible if the Arbitration Act 2010 were amended to allow Irish courts refuse to enforce CETA awards that infringed constitutional identity. Costello has significant implications for the future of CETA and investor-state arbitration agreements more generally. Moreover, the Court’s invocation of ‘constitutional identity’ raises questions as to whether the Court might later seek to join the transnational dialogue with the CJEU on the scope of EU law. In this seminar, we will explore the reasoning and implications of Costello first from the perspective of Irish constitutional law and then from the perspective of international economic law and EU law.
