v t e

The European Union Act 2011 (c. 12), was an Act of the Parliament of the United Kingdom, requiring a referendum be held on amendments of the Treaty on European Union or the Treaty on the Functioning of the European Union.

Introduced in the House of Commons by Her Majesty's Principal Foreign Secretary, William Hague on 11 November 2010, the Bill received its Second Reading by 330-195 on 7 December, and was passed by the Commons on 8 March 2011. The Bill was read a second time in the House of Lords on 22 March, after a hostile reception by Peers. The Act received Royal Assent on 19 July 2011.

The Act was passed as a reaction to the European Union (Amendment) Act 2008, which had in the United Kingdom and Gibraltar instituted the Lisbon Treaty with no participation by the Labour Prime Minister of the day, Gordon Brown and with no referendum,^[1] although one had been promised in 2005 in the Labour manifesto.^[2]

The Act was repealed by the European Union (Withdrawal) Act 2018.^[3]
