European Union Bill

That is certainly true, but I remind the hon. Gentleman that both the Single European Act and the Maastricht treaty involved a much greater transfers of powers than anything we have seen since and the Foreign Secretary voted against a referendum on such matters. Let us talk not only about consistency on this side, but about consistency by those on the Treasury Bench, too. The Government have decided to opt in to eight pieces of justice and home affairs legislation since the general election. The hon. Member for Daventry has mentioned one of them—the European investigation order. The Opposition would have liked to have had a say on the Government's decision not to opt in to the EU directive to combat human trafficking. Indeed, we judge the Government's decision not to opt in to be a dereliction of duty as regards combating this modern form of slavery. I imagine that some Back Benchers sitting behind the Minister—as I have said, the hon. Member for Daventry has mentioned this—would have liked more time on the Floor of the House to discuss not only the European investigation order but the other seven measures that the Government opted into. Another area that the Government have totally neglected to mention in the Bill is the wholesale transfer of the body of justice and home affairs legislation to the jurisdiction of the European Court of Justice. The decision that the Government have to take in 2014 either to opt in to the body of legislation in its entirety or not to do so was also referred to in the Minister's written ministerial statement last week, but it is not mentioned in the Bill and is surely of equivalent significance to many of the changes in clause 6. In fact, the Conservative party manifesto stated that the Conservatives wanted to repatriate powers in employment and social affairs and criminal justice. In his ministerial written statement, the Minister said there would be a vote in the House on the decision in 2014—we welcome that. However, I am sure that some of his Back Benchers will tell him that it is his best chance to repatriate powers in the field of criminal justice. Such a move would be unilateral and could be carried out with relative ease. The Government will not be able to do the same in the field of employment and social affairs without the unanimous agreement of all the other 26 member states. Given that this is the Government's only chance to fulfil that manifesto commitment, are they minded to take up this opportunity? Are not these changes more important than those in clause 6?
