My hon. Friend has raised two important points. I will address both of them. He refers to the temporary transitional extension. The option that is proposed to extend that transitional period for a significant time would require secondary legislation to override the primary treaty right of the UK to opt out of measures and would effectively override the opt-out itself. That is a precedent that no one would want to set. A transitional decision is proposed by the European Commission. We have no vote on its adoption. We would have no power to amend the drafting of the decision and it could extend to all 135 measures and make them subject to ECJ jurisdiction to boot. That would effectively hand over our power on this matter to Brussels, which would determine it for us. I think that that would run entirely counter to our aim of bringing powers back from Brussels.
The other point is that it has been clear in discussions we have been having with the European Commission that the purpose of the transition arrangement was, for a very limited period, potentially to ensure that while the process of opting in was taking place there was no operational gap, so that we would make sure there was no point at which it was possible for somebody to claim that an arrest warrant, for example, was no longer operational as a result of the decisions we had taken.
In relation to the suggestion that we could have negotiated a separate treaty with the European Commission, reference is often made to the Danish position on that, but in fact that is different as the Danes have no alternative option for participating in the JHA measures. Protocol 36, the opting-out decision protocol, sets out our ability to opt out and to rejoin these JHA measures, so it puts us in a different position. The EC argues that that provides us with an adequate ability to go into these measures, and therefore renders a third-country agreement unnecessary.
Given my hon. Friend’s interest in European Court of Justice jurisdiction, the other point I would make is that in all the measures Denmark has negotiated separate arrangements on with the EC, it has been required to submit itself to the jurisdiction of the ECJ. That has been the price of getting the negotiated agreement with the European Commission, so I really do not think it is an option that resolves the issues my hon. Friend and others have concerns about.
