11.This document set out the following Government commitments:
“We will ensure that there is no further transfer of sovereignty or powers [from the UK to the EU] over the course of the next Parliament… Any proposed future treaty that transferred areas of power, or competences, would be subject to a referendum on that treaty – a ‘referendum lock’... The use of any passerelle would require primary legislation.”
“We will examine the case for a United Kingdom Sovereignty Bill to make it clear that ultimate authority remains with Parliament.”
12.The Minister for Europe made a statement in the House of Commons on 13 September 2010 (HC Deb, cols 31–33WS) setting out that these commitments would be provided for by this Act, as would the necessary Parliamentary approval of the Transitional Protocol on MEPs. The Minister for Europe also stated that in specified cases where the existing Treaties provide for decisions that would transfer power or competence from the UK to the EU, these decisions would also be subject to a referendum. This statement was repeated by Lord Howell of Guildford in the House of Lords on 27 September 2010 (HL Deb, cols 170-172WS).
13.Lord Howell of Guildford made a statement in the House of Lords on 6 October 2010 (HL Deb, cols 5–6WS) setting out that the Government had examined the case for a statutory provision on Parliamentary sovereignty, and had decided to include such a provision in the European Union Bill. This statement was repeated by the Minister for Europe in the House of Commons on 11 October 2010 (HC Deb, cols 3-4WS).
