The Referendum

Treaty of Lisbon: Article 50 and its invocation

Article 50(1): ‘Any Member State may decide to withdraw from the Union in accordance with its own constitutional requirements’ WHAT ARE ‘CONSTITUTIONAL REQUIREMENTS’? POSSIBILITIES: 1. Decision by PM under prerogative or 2. Constitutional Convention requires parliamentary deliberation before notification or 3. Decision not by PM but Act of Parliament or 4. Must also consult/get consent of devolved governments CAN OTHER STATES TRIGGER PROCESS?

What happens once triggered? Article 50(2): ‘In the light of the guidelines provided by the European Council, the Union shall negotiate and conclude an agreement with that State, setting out the arrangements for its withdrawal, taking account of the framework for its future relationship with the Union. That agreement shall be negotiated in accordance with Article 218(3) TFEU.’ The roles of the UK Parliament and EU institutions Can Art 50 be stopped once triggered ?

What can and can’t be negotiated? SHOULD UK JOIN EEA TO REMAIN IN SINGLE MARKET? Legal security for exports from the UK to EU (and vice versa). Could be quick, reducing uncertainty, UK already part of EEA, and arguably no process to join it. Would leave UK free to sign own trade deals with other countries. UK not be bound by CCT, CAP, CFP or VAT policy. EEA doesn’t cover foreign policy or criminal law, although UK could make separate deal on those issues EEA covers most EU laws on workers’ rights and environment EEA membership only option to guarantee financial services similar access to IM as under EU.

Or WTO as default?

Immigration, refugee and asylum obligations Acquired rights? Non EU Asylum and migration ECHR protection

Approving the final deal

What happens if there is no agreement after two years?

UK constitutional implications of Brexit: The European Communities Act (ECA) 1972 Gateway of EU law into UK law. Incorporates EU law (UK dualist). Has to be repealed. ECA 1972, s 2: ‘[a]ll such rights, powers, liabilities, obligations and restrictions from time to time created or arising by or under the Treaties…are without further enactment to be given legal effect or used in the United Kingdom’ Disentangling UK and EU law: In addition to ECA repeal, 3 different types of law to consider: a). Directly applicable EU laws - EU regulations and parts EU treaties b). Secondly, Statutes which implement EU directives or other obligations. c). Thirdly, numerous UK regulations made under s.2(2) ECA 1972 to implement directives.

 Implications for Devolution - Good Friday agreement - EU law incorporated into devolution statutes: s. 29(2)(d) Scotland Act 1998, ASPs incompatible with EU law are ‘not law’. Sewel Convention. - E&W leave EU and Scotland and Northern Ireland remain? Greenland precedent?
