My Lords, I thank all noble Lords for attending this debate. The first of these instruments, the Justification Decision (Scientific Age Imaging) Regulations 2023, sets out the affirmative decision made by the Lord Chancellor and Secretary of State for Justice on the Home Office’s application to use ionising radiation, also known as X-rays, as a scientific method of age assessment for age-disputed individuals subject to immigration control.
The second instrument, the Immigration (Age Assessments) Regulations 2023, has been laid by the Home Office to specify scientific methods of age assessment, namely analysis of X-ray and MRI images of certain body areas. By specifying scientific methods in this instrument, a decision-maker will be required to take into account a refusal to consent to the specified methods without good reason as damaging to an age-disputed person’s credibility.
On the use of X-rays, I remind noble Lords that the Ministry of Justice, as the justifying authority, has determined the practice justified under the Justification of Practices Involving Ionising Radiation Regulations 2004.
A regret amendment has been tabled by the noble Baroness, Lady Brinton, against both statutory instruments, and therefore the debates have been grouped. The Ministry of Justice has made the justification decision independently from the Home Office, as required by the 2004 regulations. I am sure noble Lords will understand that I cannot speak to this justification decision, as it is imperative that the justification authority is functionally separate from all other persons concerned with the promotion or utilisation of the practice. However, I can speak to the process the Ministry of Justice undertook to make this decision.
I turn first to that instrument. Under the Justification of Practices Involving Ionising Radiation Regulations 2004, the Lord Chancellor has the powers as the nominated justifying authority to determine whether the individual or societal benefits of this practice outweigh the health detriments, and therefore whether it can be justified. Following a thorough statutory application, consultation and decision-making process, the justifying authority has determined that the Home Office’s proposed practice was a new class or type of practice and that this can be justified, subject to the following conditions.
The first condition is that scientific age assessment involving ionising radiation is limited to radiography of the third molar and/or of the hand and wrist only. The use of computed tomography, or CT, scans for the purposes of assessing age is not permitted. The second is that the results of radiography of the third molar and/or of the hand and wrist must be used to assess only whether there is more support of the claimed age of the age-disputed person, or the age that assigned social workers have assessed them to be following a Merton-compliant age assessment. A likelihood ratio approach must be used to compare the weight of evidence.
