I entirely accept that. We will try to ensure that we do what we can to supply the right information to Committees in the future.
The right hon. Member for Leicester East (Keith Vaz), who is no longer in the Chamber, made the valuable point that we should be cautious about the issue of jurisdictions. That is what lies behind my concern about measures such as these. It is important to understand that an opt-in is not—as was implied by the hon. Member for Swansea West—a simple process. It is not just about setting an example to the rest of Europe. It is about accepting the jurisdiction of an international court in regard to important areas of law. As was pointed out by my hon. Friend the Member for Stone (Mr Cash), there is no right of appeal following a ruling from the European Court of Justice. My hon. Friend also rightly observed that our judiciary are increasingly concerned about the role of international courts. On a number of occasions recently, they themselves have suggested that decisions that should be made in our courts and our Parliament are now being dealt with on the international stage. It is clear that that is causing some discomfort to at least some of them.
