Technology and the Law Policy Commission - Algorithms in the Justice System

Tech graphic

The Law Society of England and Wales has a strong interest in the impact of technology and data use on human rights.

To help us understand this very broad issue, we are examining one specific aspect: the use of algorithms in the justice system.

About the Commission

The Law Society’s Public Policy Technology and Law Commission will examine the use of algorithms in the justice system in England and Wales and what controls, if any, are needed to protect human rights and trust in the justice system.

Law Society president Christina Blacklaws is the chair/main commissioner. Her co-commissioners are Sofia Olhede and Sylvie Delacroix.

The commissioners will be taking evidence from a range of experts (tech, government, commercial and human rights) on whether algorithms and their use within the justice system should be regulated, and if so, how.

Terms of reference

The Commission will maintain an England and Wales focus, but take appropriate account of international developments.

It will engage openly with interested parties, providing opportunities to submit evidence and proposals and to set out views relevant to its work, including academics, tech specialists, government, civil liberty organisations and solicitors, in order to build consensus in support of its approach and recommendations.

In parallel, our policy team will be conducting a series of one-to-one interviews with key stakeholders to gather qualitative data that will inform the final report.

The Commission reported in early 2019 on:

  • its assessment of the evidence on the nature and scale of the use of algorithms in the justice system in England and Wales
  • its recommendation(s) for immediate actions to safeguard human rights and maintain public trust in the justice system.

The assessments and recommendations in the Commission’s report will be underpinned by a detailed review of the evidence on the current use of algorithms in England and Wales, forecasts for how these are likely to develop, and how they should be regulated.

She has held three research fellowships while at UCL: UK Engineering and Physical Sciences Springboard fellowship as well as a five-year Leadership fellowship, and she now holds a European Research Council Consolidator fellowship.

Before joining UCL, Sofia was a senior lecturer of statistics (associate professor) at Imperial College London.

Sofia has contributed to the study of stochastic processes; time series, random fields and networks. She is a member of the ICMS Programme Committee, the London Mathematical Society Research Meetings Committee and the London Mathematical Society Research Policy Committee. She is an associate editor for Transactions in Mathematics and its Applications.

Sylvie Delacroix

Sylvie DelacroixProfessor Delacroix focuses on the intersection between law and ethics, with a particular interest in Machine Ethics, Agency and the role of habit within moral decisions (Habitual Ethics?, Bloomsbury, 2019).

Her current research focuses on the design of computer systems meant for morally-loaded contexts. She is also considering the potential inherent in 'bottom-up' Data Trusts as a mechanism to address power imbalances between data-subjects and data-controllers (in collaboration with Neil Lawrence).

Professor Delacroix’s work has notably been funded by the Wellcome Trust, the NHS and the Leverhulme Trust, from whom she received the Leverhulme Prize.

She is also a Fellow of the Alan Turing Institute.

Current use of algorithms in the justice system

Durham Police use the HART algorithm, which assists custody officers in deciding whether a suspect should be released, kept in the cell, or made eligible for a local rehabilitation programme.

Kent Police use the PredPol programme, which informs them of crime hotspots. PrePol uses artificial intelligence to learn crime patterns from historical records.

The Kent system was trained on five years of crime data, and the algorithm is now updated daily with the force's most recent three years of records. After crunching the data, PredPol returns a daily list of 180 hotspots, each 500 ft by 500 ft, where it predicts the crime risk is high.

South Wales Police use facial recognition technology to identify wanted criminals. They have trialled it at large events - such as boxing matches, the Champions League final and rugby games - with very mixed results. The Met Police have also trialled the technology at the Notting Hill Carnival.

Report

We have published a report on the use of algorithms in the criminal justice system.
