Let us be in no doubt about that, as my right hon. Friend and distinguished colleague says—and more power to his elbow.
Let us for a moment return to first principles and remind ourselves why the United Kingdom, alone among member states, has a block opt-out. In this context, it is worth remembering that we do not of course have a written constitution, and that gives us flexibility, unlike every other member state. We are not therefore insular or isolationist in taking such a view; as I know both Secretaries of State will appreciate, we are exercising our democratic right to express our views in a free forum—this House of Commons, to which we are elected to represent our constituents—and, as Chairmen of three significant Select Committees, we have worked together on an all-party basis to agree a view on a matter of such importance.
United Kingdom Governments of all political persuasions have been wary of extending the full jurisdiction of the European Court of Justice to EU police and criminal justice measures—that has been true of Governments of all parties—because they have recognised that conferring primacy on a court beyond the jurisdiction
of the United Kingdom, and of our Supreme Court and of this Parliament, is a very profound and grave constitutional step.
Whatever views may be expressed in the debate—some will perhaps advocate opting back in to a far wider range of measures, while others will say, “None at all”; and when it comes to the vote, there may be splits and fragmentations in political parties on both sides of the House—I say to the Secretaries of State that surely we can all agree on the significance of the negotiations on which the Government are about to embark and the vital need for Parliament to have a genuine say and vote at the right time, before the negotiations have been concluded, on a matter of profound practical and constitutional significance, which bears very heavily on the liberty of the subject. What matters now is not what we have opted out of, but what measures we propose to rejoin. I ask my right hon. Friends to consider this very carefully: this is the time for the Government to think again.
On the basis of the leaks and information about the discussions that come through to us in various shapes and forms, I have referred to what has been happening in many countries throughout the European Union, and I understand that very little headway has been made in negotiations so far. My right hon. Friend the Home Secretary shakes her head. Perhaps she would like to get up and tell us that everything is going fine.
I trust that today’s debate will cause the Government to think again and allow Parliament to vote on these important measures before the negotiations are concluded. This matter of principle needs to be settled not after the horse has bolted, but now, so I tell my right hon. Friends that this is the moment. This serious matter is of grave concern to many of our citizens, and this is the time to think again.
