On 21 April 2026, the UK’s High Court of Justice in Shaun Thompson and another v The Met Police Commissioner [2026] EWHC 915 (Admin) (“the Case”) dismissed a human rights challenge to the Metropolitan Police’s use of Live Facial Recognition (“LFR”). The ruling is the first since Bridges to approve the police use of LFR. It also comes at a critical moment, with the police preparing to roll the technology out across the country. The Court’s reasoning is measured. Yet by answering only one question, it left the more decisive issue unresolved: whether the mass scanning of innocent faces is a proportionate interference at all.

The first claimant, Shaun Thompson, was wrongly matched by LFR to his brother, who was on the police watchlist, and as a result of that mistaken identification, Mr. Thompson was questioned and threatened with arrest [17, 141-142]. He was joined in the challenge by Silkie Carlo, director of the civil liberties group Big Brother Watch. The claimants’ case was not that LFR is inherently unlawful. It was that the Policy gives police officers excessive discretion over where, why, and against whom the technology is deployed, thereby breaching Articles 8, 10 and 11 of the European Convention of Human Rights (ECHR). The Policy confines deployment to three primary use cases: (i) crime and missing-person hotspots, (ii) protective security operations, and (iii) specific-intelligence operations. For each, it further sets out the categories of people who may be placed on the watchlist, ranging from those suspected of offences relevant to the hotspot to those wanted by the courts or subject to court orders [110, 113, 115]. The Equality and Human Rights Commission (EHRC) intervened, submitting that the watchlist composition (who) was largely disconnected from the location (where) and objective (why) of deployment, producing “indiscriminate and arbitrary processing”. The Court did not agree. The why, who, and where questions, it held, “form interlocking parts of a Policy that does not authorise the making by the police of arbitrary decisions” [217]; read “fairly and as a whole” [227], the Policy was “a far cry from the “hunch” or “professional intuition” of an individual officer” [200].

The Question the Court Chose

The framing of the issues was the defining feature of the case. The Court held that a challenge based on foreseeability “does not involve a challenge to the proportionality of the measure” [14]. The claimants rather pleaded the former: whether the Policy had the required “quality of law”, and did not argue necessity or proportionality. That meant the Court’s decision was limited. It did not decide whether scanning large numbers of faces was itself justified. Foreseeability asks whether people can know the rules under which they are surveilled; necessity asks whether that surveillance should happen at all. By resolving the case on the first question alone, the Court reviewed the rulebook, but left the practice untested.

The Missed Opportunity

This is where the Case, despite its careful reasoning, falls short. The way a question is framed can shape the answer it receives, and here the framing foreclosed the deeper inquiry.

First, the Court was content to treat a police officer’s self-authored operational policy as the law that authorises indiscriminate biometric capture. The Court upheld LFR without any dedicated facial-recognition statute, and instead accepted a patchwork framework [45, 64], for the operational detail of who, where, and why. The foreseeability doctrine permits this, since “the rules governing the scope and application of measures need not be statutory, provided they operate within a framework of law” [37]. That conclusion rests on classification inherited from Bridges, that LFR is not an “intrusive” method requiring specific statutory legitimacy [43 – 44]. The result is that a uniquely powerful biometric capability operates without any FR-specific legislation and a parliamentary mandate. This is a democratic-legitimacy gap that the foreseeability test was never built to answer.

Second, the Case does not engage with the Glukhin v Russia, even though the EHRC placed it before the Court. Glukhin had a direct bearing on the “quality of law” limb decided here. It called LFR “highly intrusive” [90], demanded “high level of justification…considered necessary in a democratic society” [86], and warned “the need for safeguards will be all the greater” for LFR [82]. On the same question, as such, Strasbourg went the other way.

Third, foreseeability has a human cost. The judgment records Mr. Thompson’s mistaken identification as a fact, but the Court’s narrow frame leaves that experience with little legal weight. A policy can be clear on paper and still produce damaging errors in practice, especially for communities already exposed to heavier policing. A proportionality analysis would have had to confront that reality. A foreseeability analysis does not.

Conclusion

The case is not wrongly decided on the question it answered. The Policy is clearly more detailed, and more constrained, than the framework rejected in Bridges. Yet that is not the same as saying LFR is compatible with human rights. The judgment approves the legal form of the power while leaving its necessity largely unexamined. The claimants have confirmed they will appeal, and the appellate court may yet ask the question this Court left open: not whether the rules are knowable but whether scanning millions of innocent faces can ever be necessary in a democratic society. Until that question is answered directly, the legality of facial recognition in the UK rests on a narrower foundation than the headlines suggest.
