That is kind, but I will make some progress; otherwise I will lose the thread in relation to amendment 303. The amendment is at odds with the clear and certain position set out in the Bill, because it would continue to bind UK courts to some post-exit ECJ decisions and case law where the matters giving rise to the case have occurred before our exit. Those judgments would continue to be binding even after an implementation period. Strictly interpreted, the amendment would go further still. It would apply to anything happening before exit day and so would also include ECJ judgments on cases referred from outside the UK. For example, a preliminary reference made by another EU member state in relation to the interpretation of EU law might also fall within the scope of the amendment, if the facts of the case arose before exit day. The consequences would be far-reaching and risk creating considerable uncertainty and practical difficulties for the administration of justice. UK courts and tribunals would continue to be bound by some new ECJ judgments for an indeterminate period. Those binding judgments could continue to be issued long after we have left the EU as cases continue to progress to the European Court from across the EU. Yet those judgments would not have formed part of the snapshot of retained EU case law that, under clause 6(3), will be binding on our courts, so far as is relevant, and subject to the rule in clause 6(4). By contrast, such post-exit judgments would bind our courts in all circumstances, including where the retained version of an EU regulation had since been modified by this Parliament or a devolved Administration. That would create foreseeable and entirely avoidable uncertainty, and it would not be necessary, because individuals whose cause of action predates our exit would, of course, continue to be able to take their case to the domestic courts, even if after exit they cannot reach the European Court. That is the fundamental point in relation to the procedural framework. I now turn to amendment 304, tabled by my right hon. Friend the Member for Chesham and Amersham, in relation to retaining ECJ referrals and jurisdiction for anything that happened before exit day. In leaving the EU, we will bring an end to the jurisdiction of the ECJ-we have made that clear. The proposed amendment would frustrate that objective, because our courts could continue to make references to the ECJ in relation to cases where relevant matters have occurred before our withdrawal from the EU. As a result, different rules and processes would apply for those cases, compared with those where the relevant circumstances arose after exit day. That would, I fear, give rise to more not less uncertainty, because it would be impossible to predict for how long UK courts would continue to be subject to binding judgments from Luxembourg. When we exit the EU, we will know exactly how many pending UK cases are registered with the European Court, awaiting a preliminary reference and thus covered by any proposed agreement we have with the EU on the treatment of pending cases. That is important to deliver certainty about how and when the Court's jurisdiction in the UK will be brought to an end. The amendment would remove that certainty. Like amendment 303, it is not necessary. Individuals will not lose their ability to vindicate their rights in court after exit. They will be able to take such cases to our domestic courts. Forgive me, Sir David, but I thought it necessary to address my right hon. Friend's amendments in detail. Equally, I want to say that I recognise the eloquence and the force with which she champions her constituents. Ministers will take away the underlying issue that she has brought and powerfully moved for consideration. I hope that on that basis she will not feel she needs to press the amendment.
