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

Lord Hunt of Wirral Excerpts

Monday 28th November 2022 Grand Committee

[Lord Hunt of Wirral (Con)]

My Lords, I draw attention to my entry in the register, in particular to my role as a partner in the international commercial law firm, DAC Beachcroft. I am very much aware from that separate strand of my life how law firms are increasingly under pressure from their clients to make use of automation and AI. This can lead directly to efficiencies and cost savings. It also offers up the longer-term possibility of developing and licensing self-serve law tech solutions to replicate some of the services that law firms have traditionally provided, reducing the dependency on lawyers. In a highly competitive market, technology can make all the difference. So, both as a lawyer and a legislator, I warmly welcome this debate. I congratulate the noble Baroness, Lady Hamwee, for her impressive opening speech, her leadership of the select committee and her wise guidance in helping us to produce a very persuasive report.

I dare say that all reports suffer to some extent from in-built obsolescence, especially those dealing with technology. However, I hope that by going back to first principles, the committee has given this one sustainable life and relevance. As we read our way into these questions and raised them with witnesses, I think it is fair to say that we grew more, not less, concerned about the implications for the rule of law of the burgeoning technologies that are increasingly available.

The very good report we produced by consensus with the help of our excellent support team makes our sense of concern—even alarm—very overt and apparent. Our inquiry left me in no doubt about the scale of the challenge we all face to ensure that new technologies serve the best interests of justice and the public interest more widely.

Some noble Lords may have heard or read a highly stimulating lecture earlier this year by the Master of the Rolls, Sir Geoffrey Vos, in which he mused on the significance for us all of

“the inexorable rise in blockchain technologies”,

which will

“immutably record every event or transaction in our lives.”

He also predicted that a

“truly integrated online digital justice system to resolve civil family and tribunals disputes”

would be in place in England and Wales by the mid-2020s at the latest. It is quite a thought.

It is very easy to be seduced by the technologies themselves, but I would like to pull focus to questions of transparency, governance and accountability. We are told that much accountability within the system now rests with police and crime commissioners. My own dealings with such a commissioner give me no reassurance at all—quite the opposite, in fact. I do not believe that PCCs can provide adequate or even meaningful accountability, especially where fast-moving technology is concerned. They lack the necessary expertise and, looking at some of the turnouts in PCC elections, they lack the authority too.

With both the criminal and civil justice systems so overstretched and behindhand, it is all the more tempting to succumb to the allure of the glittering baubles of high tech, AI, algorithms and all the rest, with the promise they appear to offer of a faster, slicker set of outcomes. If we are also persuaded that those outcomes are also more just and fairer, with human fallibility stripped out, the Lorelei cry may prove irresistible. Yet, again and again during the course of our inquiry, we heard from experts how algorithms, however sophisticated, can be “gamed”. If this is true, I wonder whether algorithms can ever truly be fit for purpose within a justice system.

It all takes us inevitably back to the old, uneasy, irreconcilable tension between the supposedly sacrosanct principle of operational independence versus the ultimate need for accountability to prevent a police force or chief going rogue, which, as I have witnessed myself, does indeed happen from time to time, although fortunately rarely. I am becoming increasingly troubled by what we call “fairness metrics”. We hear much talk of using AI, not simply to deliver the status quo more effectively and efficiently, but actively to make society “fairer”—a subjective and loaded term, if ever I heard one—by rectifying perceived social, economic and other inequalities. If that initiative acquires significant momentum, we as parliamentarians must surely be profoundly concerned about what is being factored in.

I see a clear analogy here with the development of automation and AI in the automotive sector. We were told six or seven years ago that driverless cars would be on our roads by 2021. The reality is, they are still not here. Safe implementation is a vital consideration, as is the need for an appropriate legislative and regulatory framework both pre and post placement and, ideally, through testing in a sandbox environment to ensure the veracity and reliability of algorithms.

Rushing the implementation of automation and AI would be damaging enough in the context of automated vehicles, but getting it wrong risks pushing back mass-market adoption of technologies designed to improve productivity and mobility. A similar mistake is surely inconceivable and wholly unacceptable in the context of the criminal and civil justice systems. Who is keeping a close eye on all this? Is it Ministers?

I am sad that the noble Lord, Lord Blunkett, is not here. To quote from the evidence that we received from the Minister, when I asked at question 107,

“Will you be keeping a careful eye on this?”


The Minister responded,

“That is a very good question which I will have to think about … We have some brakes and levers that we can pull”.


At that point, the noble Lord, Lord Blunkett, said,

“There are ways and means, I promise you.”


At the end of the day, that is what this debate is all about. Who is keeping a careful eye? Is it officials? If it is, from which of the plethora of departments and public bodies that are active in this field will they emerge?

We come back to accountability. Who has practical, day-to-day responsibility for the legal, ethical and active use of advanced technologies of this kind? Who has day-to-day decision-making powers, and where is the practical transparency and ultimate accountability? The reality is always that ultimate responsibility must rest with Ministers and Parliament. The Executive takes the decisions and faces the scrutiny of the legislature in either or both of our Houses of Parliament. The question then is how to make that work quickly, effectively and reliably.

It is perhaps inevitable that a report of this kind raises more profound questions than it would ever be capable of answering, especially when addressing so complex and controversial a topic. I was worried at the time of publication that we would not succeed in our aim of moving Ministers to share our concerns. The trials and tribulations within the Government in recent months have not served to calm my fears. Now we appear—I stress, appear—to be in a period of much-needed stability again. I hope we catch the eyes and ears of Ministers and make a difference, for in the field of radical innovation, just as in the field of criminal and civil justice, prevention of an undesirable outcome is invariably preferable to cure.
