Technology Rules: The Advent of New Technologies in the Justice System (Justice and Home Affairs Committee Report)

Baroness Primarolo Excerpts

Monday 28th November 2022 Grand Committee

[Baroness Primarolo (Lab)]

My Lords, I will make a small contribution to this debate as a member of the committee but, first, I pay tribute to the noble Baroness, Lady Hamwee. She steered our committee through complex and, at times, contradictory evidence to try to make sense of what, as the noble Lord, Lord Hunt, said, is a rapidly changing and developing area. Her opening remarks in this debate said, with great eloquence, exactly which problems the committee identified and our fears for the implications for the justice system if those problems are not addressed. The noble Lord, Lord Hunt, referred to the prediction of driverless cars. The issues addressed within our justice system are cumulative and the problem will be too large to address if we do not take these very small steps at the beginning.

I welcome the Minister to this debate. I recognise that this is a complex area of policy and that the Government are trying to catch up, balancing all sorts of priorities, while the technologies continue to develop and change.

Your Lordships and the Minister will see from the committee’s report that we raised concerns, particularly about the risks to human rights and civil liberties as a result of the increasing use of these advanced technologies, and particularly in the police forces, which was our focus. We stopped there because the subject was so enormous, if we had not, we would still be deliberating on the evidence. Clear questions continually emerged which remained unanswered—questions of accountability, efficacy, transparency and the potential to undermine inadvertently the basic principles of our criminal justice system.

The question that our committee kept finding itself confronted with was: what are the principles which should underpin the safe and ethical use of these new technologies in the justice system? Currently, a lack of national minimum standards, transparency, rigorous evaluation and training in the use of these technologies means that human rights and civil liberties could be compromised. Are we to wait until they are compromised before we decide to address these principles?

In endorsing this report, the committee unanimously decided that now is the time to start acting. It cannot be right that 43 constabularies are doing their own thing, most in isolation from each other, evaluating as they go along, at best—if they do it at all. However, that evaluation is not open to public scrutiny—it does not provide a route through to the point that the noble Lord, Lord Hunt, made: who is accountable? Parliament has to be accountable, and how do we discharge those responsibilities without the information in the first place? Each constabulary develops the use of the technologies to its local policing objectives and does different tasks to different levels of complexity. I am not making a case for a national police force, and neither was the committee, but it would be helpful to those constabularies to be provided with clarity from government on the basic principles that they should be observing, as this fits within the wider justice system.

Some are in no doubt—it may be the case; I do not have a crystal ball—that advanced technologies have a huge potential in assisting the police in delivering priorities and a policing system that commands confidence, trust and respect, improving efficiency, productivity and problem-solving. That is the sales pitch to the constabularies. But—and it is a very big but—these technologies have challenging and significant downsides with regard to civil liberties and human rights, as the noble Baroness, Lady Hamwee, pointed out. If not addressed, they will undermine the same confidence, trust and respect, and, if inadvertently and wrongly used, they will undermine the concept of fairness in our justice system. We should be under no illusion that if these technologies are allowed to mushroom in the police service without clear, consistent, understandable standards and protections, we will build up significant problems.

We urgently need consideration at national level of the trade-offs in using these new technologies: human rights versus interference with those rights, while ensuring that the interventions are necessary and proportionate. When we asked where the balance was, who was accountable and who was watching, answer came there none. On their effectiveness, we asked: are the public safer with these enhanced technologies and do these technologies make a difference? Again, in the absence of evaluation, answer came there none.

Transparency is a crucial principle because, increasingly, citizens want transparency about how their personal information is used and shared. Many benefits flow from transparency, including identifying problems early on and, crucially, improving the public’s trust in data-driven technologies. With that trust comes a pathway to developing appropriate technologies in supporting priorities. It happens elsewhere, so the committee suggested a central organisation or regulating body. NICE does it for the health service with regard to the efficacy of drugs. Why can it not be done in the justice system? The embryology authority balances what is possible medically with what is acceptable ethically. Why can we not use similar models?

Does the Minister think that police forces should satisfy themselves in advance of using new technologies, through independent verification, that the software program does not have an unacceptable level of bias? How can we be confident that historic cultural bias is not built into the system? Does the technology actually work and do what we want?

There are steps forward that could be taken—I know it is going to be very difficult—to deliver two central propositions recommended in this report. First, will the Minister agree to bring together the 43 constabularies, either by requiring or facilitating them, to share their knowledge and experience in this area so that we can begin the painful process of getting on the right side of this development? Secondly, will he consider appointing an expert panel of academics and practitioners to advise him on how to make progress on having the correct balance for a regulatory authority that protects us and our civil liberties, but enables the police and the justice system to do their job effectively?
