My Lords, I thank noble Lords for their contributions. I reassure your Lordships’ House that the Government are progressing workstreams focused on the accuracy and reliability of sex data in public authority datasets in a holistic and measured manner, as I have described in previous debates. We welcome the Supreme Court ruling, and are now working hard to consider those findings and the upcoming guidance from the equalities regulator, which will help.

I reiterate that the trust framework requires DVS providers to comply with data protection legislation, including the data accuracy principle, where they use and share personal data. That includes the creation of reusable digital identities, as well as one-off checks. If they fail to comply with these requirements, they could lose their certification. This means that the sex information listed on a passport—which, as we all know, could be a combination of biological sex, legal sex under the Gender Recognition Act and gender identity—cannot be used to verify biological sex.

The noble Lord, Lord Arbuthnot, asked whether a person can have different genders appearing on different documents. Yes, you could have both genders appearing on different documents, but they could not be used to prove biological sex.

I should say to noble Lords that there is a requirement for all this information to be recreated, reused and rechecked each time. In response to noble Lords who asked about historic data, the data will be renewed and checked under the new information that is now available.

In the Majority of cases where DVS are used, there will not be a need to verify biological sex, as we have noted before, because many DVS requirements do not ask that question. Data sharing under the power created in Clause 45 will involve new processing of data, which must be in compliance with the data accuracy principle: that is, it must be accurate for the purpose for which the information will be used. Of particular relevance, given that public authorities will be sharing data for verification purposes, is the fact that data accuracy principles require that the personal data must not be misleading.

With regard to the question from the noble Baroness, Lady Ludford, about supplementary codes of practice, I can confirm that the trust framework already includes requirements on data accuracy for DVS providers. That framework will, of course, be updated from time to time.

On scientific research, let me repeat my thanks to the noble Viscount, Lord Colville, for his contribution on this issue. I am glad that he was reassured by my remarks that we have been able to come to an agreeable resolution. I very much concur with the comments of the noble Lord Clement-Jones, that there has to be an ethical basis to those standards, and that point is absolutely well made.

On that basis, I hope I have reassured noble Lords. I commend the Motion to the House.
