I think that I am about to take up much more time than I wanted to. I give way to the hon. Member for North Down (Lady Hermon).

I am extremely grateful to the right hon. and learned Gentleman for allowing me to intervene. I agree entirely with his eloquent points about the power that schedule 5 transfers to Ministers of the Crown. Will he spend a moment reflecting on the definition of a Minister of the Crown that is set out in clause 14? The definition comprises not just Ministers, but

“also includes the Commissioners for Her Majesty’s Revenue and Customs”.

The power in schedule 5 is being given to a very broad range of individuals.

The hon. Lady is right. [Interruption.] Next to me, from a sedentary position, my hon. Friend the Member for Harwich and North Essex is saying, “It’ll only be used for technical matters.” Indeed—let us be clear about this—I strongly suspect that that is the intention, but this is a very extensive power and, as it is worded, it goes way beyond technical amendments. As we are in Committee, it seems perfectly proper for me, as a Back-Bench Member of Parliament—it does not matter which side of the Chamber I am sitting on—to ask my hon. Friends on the Treasury Bench to explain to the Committee how the power will be used. I gently say to my hon. Friends that the problem with this debate is that the heat that starts to come off very quickly goes into issues of principle about what has been going on over the past 50 years. Could we just gently come back to focus on the issue at hand?

As I have said, this is a power of publication. It is important not only that we formally delete it, as my right hon. and learned Friend says, but that we provide that it does not end up in the wrong place and thereby mislead the reader or those who want to find an authoritative source for retained EU law. Another example would be EU regulations that have entered into force but are only partially applicable here immediately before exit day. One example is regulation 2016/2031 on protective measures against pests of plants, which has entered into force. One provision applies now, but the rest will apply in the EU only after exit day. To answer him directly, that is why the power exists.

I shall move on to paragraphs 3 and 4. Paragraph 3, as the keenest Members will have observed, is based on section 3(1) of the 1972 Act, which provides that

“any question as to the meaning or effect of any of the Treaties, or as to the validity, meaning or effect of any EU instrument, shall be treated as a question of law”,

and, of course, when something is a question of law, a court can determine the meaning of that law for its own purposes. Foreign law is normally a question of fact to be pleaded and then proved, often by recourse to expert evidence. Quite rightly, however, we want to allow a question of EU law to continue to be treated as a question of law after exit day, for certain purposes, such as when it is necessary to decide the question of EU law for the purposes of interpreting retained EU law in legal proceedings here.

Will the Solicitor General take a moment to explain the status of the long preambles to EU regulations and directives? We are taking all this back, so what is their status to be? How will the courts interpret the preambles to regulations and directives that become part of retained EU law?

Like any other part of a document, it will, of course, have effect. A preamble is an important statement. It is different from, say, an explanatory note or accompanying document—it is part of the measure and therefore will have force. We are seeking to download that documentation and make it part of our domestic law so that when we read it across, people will know that it is part of our domestic law, albeit in that category of retained EU law.

The hon. and learned Gentleman, like everyone in the House, will be well aware that our legislation does not have long preambles. I think that the judges need further guidance. He has indicated from the Dispatch Box that the preambles will have force. What weight should the judiciary across the UK give to those preambles, as they are not accustomed to them in British legislation? What does “force” actually mean?

I think that there are many consequences on which the hon. Gentleman and I could dwell on another occasion. The fact is, however, that it is my task to try to ensure, as one of the Law Officers, that the principles of the rule of law to which my right hon. and learned Friend the Member for Beaconsfield referred in his speech—accessibility, clarity and certainty—are adhered to. We will deal with the issues so that we uphold those important principles, which were set out by the late Lord Bingham.

I am grateful to the Solicitor General for his generosity in giving way again. As he knows, we do not currently have a functioning Assembly in Northern Ireland, so we do not have Ministers who can abide by his direction about explanatory memorandums that will be issued when EU regulations and directives are brought back, in this context to Northern Ireland. Will he confirm that the Departments in Northern Ireland will have an obligation—a duty—to provide explanatory memorandums in that connection?

I think it must follow that when there is no Executive functioning in Northern Ireland and the Northern Ireland Office is carrying out functions as a substitute for the Executive, the duty will apply to that Department. I assure the hon. Lady that when we introduce statutory instruments, there will be explanatory memorandums from one source or another. Various Departments will have different responsibilities for the drafting and publication of the statutory instruments, and it will be their duty to produce the explanatory memorandums for Members to consider. I cannot envisage an exception being made. Northern Ireland will be covered in the way in which the hon. Lady wants it to be.

Paragraph 1(4) of schedule 5 enables the Queen’s printer to make arrangements to publish documents that may be considered useful in connection with anything else published under the schedule. That, I think, allows for the approach that the hon. Member for Nottingham East is requesting. We are committed to ensuring that the law remains accessible and comprehensible after exit day, and on that basis, I ask the hon. Gentleman to withdraw the new clause, which I think he said was a probing measure. He will have noted my comment, and I understand his position.

Amendments 76 and 77 have been addressed in particular by the hon. and learned Member for Edinburgh South West. Amendment 77 seeks to place the power for a Minister to make provision about judicial notice and the admissibility in legal proceedings of specified evidence of certain matters into the Bill. Judicial notice is a term that covers matters that are to be treated as already within the knowledge of the court, and are therefore not required to be “proved”, as other evidence would be, in the usual way. Amendment 76 would remove that power from schedule 5, while not replacing the provisions that clarify the scope of that power.

The power in part 2 of the schedule covers a limited, technical area, and the affirmative procedure will apply. My worry is that, with the removals that amendment 76 would make, we will lose clarity on how those powers are to be applied. I imagine that the intention of those who support the amendments is that those clarifying provisions would be inserted underneath the power, but I think that we achieve greater clarity by putting them in this schedule in the way that we have, so I respectfully ask the hon. and learned Lady and the other Members who have tabled the amendments not to press them.

Finally, I will deal with amendment 348. It is tempting for me to plunge into the debate about impact assessments and regulatory and sectoral analyses, but this is an amendment about this Bill, of course, and I remind all Members that an impact assessment for this Bill was published when it was introduced. That is in line with the general practice of Governments of different parties in recent years of publishing impact assessments alongside legislation. We want to continue pursuing that approach, but it must be done in a proportionate and appropriate way.

Amendment 348 would impose an open-ended requirement on the Queen’s printer to publish impact assessments, and could, I fear, create a duty it could not meet. The Queen’s printer does not have a responsibility to decide what should be published alongside legislation; it merely publishes what the Government ask it to, and quite rightly so, we might think. At the same time, Ministers have a specific responsibility, endorsed by Parliament, not to release information that would expose our negotiating position. This amendment would risk doing precisely that in a way that would put the responsibility on to a non-ministerial department—the Queen’s printer—which, with respect to it, is in no place to know what analysis is being undertaken, or to make a judgment about what can be published appropriately, safely and proportionately.

In the context of those remarks, I ask the hon. Member for Nottingham East to withdraw the new clause, and I support the passage of clause 13 and schedule 5 and beg that they stand part of the Bill.
