As the noble Lord knows, the Government are exercising an opt-out that was provided for by negotiations by a previous Government. Noble Lords will expect the Government to exercise their discretion in this matter and to seek the endorsement of Parliament, as they have done on this occasion. I make no apology to the noble Lord for the decision that this Government have made. It was a decision that was anticipated by the previous Government in their negotiations.
As I was saying, before I return to the points raised, I confirm that there will be another vote on the package of measures that we will apply to rejoin. It is important that Parliament is given the opportunity to scrutinise this matter fully. I am very happy to commit myself to replying for the Government during that debate later this year.
I start by responding to some of the points of the noble Lord, Lord Hannay, in his excellent speech. I could not agree with all that he was saying about the Government’s performance or decision-making or role, but he set out a number of important points that have helped to guide this debate and I am happy to reply to them.
The noble Lord, Lord Hannay, and my noble friend Lord Sharkey addressed the point of whether there are measures that are detrimental to the UK and the UK’s national interest. The noble Lord, Lord Davies of Stamford, asked if this were the case. That is one way to assess these measures. However, is not the way in which the Government have assessed them. The Government have looked at how each measure contributes to public safety and security, whether practical co-operation is underpinned by the measure and whether there would be detrimental impact on such co-operation if pursued by other mechanisms. We have considered the impact that the measure has on civil rights and liberties. We believe that the 35 measures that we are seeking to rejoin meet these criteria.
The noble Lord and the noble and learned Lord, Lord Lloyd, asked why the Government have opted in to post-Lisbon measures if we have concerns about European Court of Justice jurisdiction. The Government consider that there is always a risk attached in terms of European Court of Justice jurisdiction. All Governments have faced this when we decide to participate in measures—pre-Lisbon or post-Lisbon. However, in certain cases, it will be in the national interest for the UK to participate in these measures, and the Government will accept that risk, given the wider benefits of the instruments in question.
