I am going to make a bit of progress. Wider general definitions are set out in clause 14, and clause 15 provides an index of all the defined terms to make the Bill easier to use as a reference tool. To remove those definitions from clause 6 and only partially to reinsert them into clause 14, as the amendment would do, would undermine the certainty and clarity that we aim to provide.
Without statutory definitions of the different types of retained law, we would undermine the stability of our domestic legal regime after exit and exacerbate the burdens on the court system. Reinserting the definition of “retained domestic case law” into clause 14 would
not alleviate that, because it would give rise to the question why that definition had been included, while others had not. Its placement in the body of clause 14, away from its original use in clause 4, would make the text far less easy to navigate—something that we are keen to avoid.
I turn to amendment 137, which is a joint SNP and Liberal Democrat amendment, in the name of the hon. and learned Member for Edinburgh South West (Joanna Cherry). Clause 6(2) will allow our domestic courts and tribunals to take into account any decisions made by the European Court, an EU entity or the EU itself on or after exit day, if they consider it appropriate to do so. That will ensure that our courts are not bound by the decisions of the European Court, while enabling them to consider its subsequent case law if they believe it is appropriate to do so. It is widespread practice in our domestic courts to carry out a similar exercise with the judgments of courts in other jurisdictions—I am thinking particularly of Commonwealth and common law jurisdictions—so, in principle, there is nothing new or particularly different here.
The UK has always been an open and outward-looking country, and our legal traditions reflect that. We pay attention to developments in other jurisdictions, including common law jurisdictions, and we embrace the best that the world has to offer, but we do so on our terms and under our control. That is decided by our courts and, ultimately, it is subject to the legislative will and sovereignty of this House. Amendment 137 is therefore unnecessary, as the Bill already provides that post-exit decisions of the European Court can be considered by the domestic courts.
Amendment 137 would go further, however, in that it would require our courts and tribunals to pay due regard to any relevant decision of the European Court. What does “due regard” mean? It is not defined and, indeed, it is far from clear. It is evidently intended to go further than clause 6, and tacitly urges our courts to heed, follow or shadow the Luxembourg Court, but there is no clarity about what would count as due consideration. The amendment would alter the inherent discretion the UK courts already have to consider, without fetters, the case law in other jurisdictions, and it seeks to apply to the European Court a procedural requirement that is stronger but so vague that it is liable to create more, not less, confusion. I hope that I have tackled, or at least addressed the concerns that the hon. and learned Lady has expressed in her amendment, and I urge her not to press it.
I will now turn to amendment 303 in the name of my right hon. Friend the Member for Chesham and Amersham. I thank her for tabling this amendment and for explaining it, as she did, in a very constructive spirit. I recognise that she is representing the interests of her constituents with her customary tenacity, but I will take a few moments to set out why we have taken our approach to the issues and my difficulties with her amendment.
Clause 6 supports the Bill’s core aim of maximising certainty. It is in no one’s interests for there to be a legal cliff edge. The Bill means that the laws and rules we have now will, as far as possible, continue to apply. It seeks to take a snapshot of EU law immediately before exit day. The Government have been clear that in leaving the EU, we will be bringing to an end the direct jurisdiction
of the European Court of Justice in the UK. To maximise certainty, any question about the meaning of retained EU law will be determined in UK courts by reference to ECJ case law as it existed before our exit. Using any other starting point would be to change the law, which is not our objective. Our domestic courts and tribunals will no longer be bound by or required to have regard to any decisions of the European Court after that point, but they can do so if they consider it appropriate. These clear rules of interpretation are set out in clause 6.
