My Lords, the 2011 Act was introduced by the elected Chamber for the express purpose of safeguarding major constitutional changes in respect of our relationship with the EU and I support the amendment, to which I have added my name.
The Act, among other matters, provides for a referendum throughout the United Kingdom on any proposed EU treaty or treaty change which would transfer powers from the UK to the EU. Parliament voted for this power in order to protect the sovereignty
of the United Kingdom and it is this aspect of our constitutional framework that it is important for the Committee to be mindful of as we negotiate our future relationship with the EU. Surely the proper time for the 2011 Act to be repealed is when we conclude our relationship with the EU. However, the Bill as it stands allows a Minister to repeal it at any time after Royal Assent.
The Conservative Party manifesto in 2010 led to this Act. It is worded not in terms of transfers of power but in terms of the extension of the competence or objectives of the European Union and decrease in the voting power of the United Kingdom. If we go into a transition period, there will be a new form of treaty relationship with the EU, one in which the UK has surrendered powers to the EU. The transition or implementation phase is a subordination of power to the EU 27 and binds us to them with fetters in a new international treaty. I contend that even if one believes wholeheartedly in leaving the EU there are strong grounds not to repeal this Act before we have actually and finally departed. Parliament does not yet have the terms of any deal for Brexit, nor will it have before Royal Assent. I therefore believe that it is vital that the 2011 Act is not repealed in this Bill as that would remove a safeguard which currently exists to protect the United Kingdom and our constitutional position. Parliament enacted that legislation for a specific purpose and Ministers should not be allowed to repeal it at will without proper debate and discussion unless we have already concluded our exit terms.
The other place did not have an opportunity to debate this amendment and it seems to have been missed, or perhaps honourable Members might have assumed that the repeal of the Act would apply only on the date of exit, but it turns out that it could be before that date by ministerial diktat. Given the uncertainty that still surrounds this Bill and the entire Brexit process, as well as the lack of clarity on our future relationship, I urge my noble friend the Minister to agree to this amendment. It safeguards the constitutional position enacted by Parliament in 2011 and maintains the sovereignty of Parliament over the Executive to protect the UK from deleterious treaty change that has not received prior approval from Parliament or the people.
