Domestic Abuse Bill

Debate between Baroness Garden of Frognal and Lord Marks of Henley-on-Thames

Committee stage & Committee: 5th sitting (Hansard) & Committee: 5th sitting (Hansard): House of Lords
Monday 8th February 2021 Lords Chamber

[The Deputy Chairman of Committees (Baroness Garden of Frognal) (LD)]

My Lords, I am afraid that we have had no luck getting in contact with the noble and learned Lord, Lord Morris, so I call the noble Lord, Lord Marks of Henley-on-Thames.

[Lord Marks of Henley-on-Thames (LD) [V]]

My Lords, I am grateful to the noble Lords who have spoken in this debate and to the Minister for his careful response. I echo both his thanks to those in his department who organised the learning session last week and his view that it sets a good example; it would be very good to hear more often from experts in the department—particularly about the use of technology, where Members of this House perhaps have less expertise than they do in other legal areas.

My noble friend Lady Hamwee asked a number of questions, some of which were answered by the Minister. I am not sure that he addressed the question of what is meant by, and what the criteria are for, “high-risk” perpetrators. She also wanted to know what exactly is meant by “failing” a test; I understand, as did the Minister, the concept of evaluating a test, but there is a problem with our general understanding of results of polygraph tests as binary and with the use of the term “failed test”, which frequently figures in discussions around this issue. Given his echo of the description of answers as “somewhere between yes and no”, as expressed by my noble friend Lady Hamwee, the Minister clearly appreciated that these tests cannot provide definitive answers. Will he and others give consideration to how far they should be treated as more indicative than binary?

I am less concerned about the use of information, as described by the Minister, that is derived from polygraph testing and used to submit information to the police for further investigation, which would then come up with real evidence. I am, however, a little concerned about recall based on disclosures. I understand the point that there is some similarity between disclosures that arise as a result not of polygraph testing but of, for instance, discussions with probation officers; however, I still think that there need to be safeguards. The Minister may like to consider those and put out some guidance as to how they are to be dealt with.
