Welsh police force's use of facial recognition technology ruled unlawful in landmark Court of Appeal case

A UK police force’s use of facial recognition technology has infringed on privacy and data protection laws, the Court of Appeal has ruled in a landmark hearing over the controversial tool. Civil rights campaigner Ed Bridges brought a legal challenge against South Wales Police, arguing that their use of automatic facial recognition (AFR) had caused him “distress”. AFR is used by South Wales Police to live-capture the facial biometrics of large numbers of people and compare them with people on a “watchlist” – which can include suspects, missing people and persons of interest.

The facial biometric data of anyone whose image is captured on CCTV but does not generate a match is not retained. Mr Bridges, 37, had his face scanned while he was Christmas shopping in Cardiff in 2017 and at a peaceful anti-arms protest outside the city’s Motorpoint Arena in 2018. In a ruling on Tuesday, three Court of Appeal judges ruled that the use of the technology was unlawful and allowed Mr Bridge’s appeal on three out of five grounds he raised in his case.

Mr Bridges took his case – believed to be the world’s first over police use of such technology – to the Court of Appeal after his action was previously rejected by the High Court.

At a three-day Court of Appeal hearing in June, lawyers for Mr Bridges argued that the facial recognition technology interferes with privacy and data protection laws and is potentially discriminatory. In Tuesday’s judgment, the Court of Appeal judges said the High Court erred when it concluded that the force’s interference with Mr Bridge’s right to a private life was “in accordance with the law” under human rights laws. They ruled that there was no clear guidance on where AFR Locate – the system being used by South Wales Police in an ongoing trial – could be used and who could be put on a watchlist, and this left too much discretion to police officers.

South Wales Police is not intending to appeal against the judgment.

The ruling said: “The fundamental deficiencies, as we see it, in the legal framework currently in place relate to two areas of concern. “The first is what was called the ‘who question’ at the hearing before us. The second is the ‘where question’.

“In relation to both of those questions too much discretion is currently left to individual police officers. “It is not clear who can be placed on the watchlist, nor is it clear that there are any criteria for determining where AFR can be deployed.” It added that the court is satisfied “that the current policies do not sufficiently set out the terms on which discretionary powers can be exercised by the police and for that reason do not have the necessary quality of law”.

In their ruling, Master of the Rolls Sir Terence Etherton, President of the Queen’s Bench Division Dame Victoria Sharp and Lord Justice Singh, did find that the use of AFR was proportionate under human rights laws as the potential benefits of it outweigh the impact on Mr Bridges. The court also concluded that a data protection impact assessment of the scheme was deficient and that the force had not done all it could to verify that the AFR software “does not have an unacceptable bias on grounds of race or sex”. The judgment noted that there was no clear evidence that the software was biased on grounds of race or sex, however.

The judges said they hoped that “as AFR is a novel and controversial technology, all police forces that intend to use it in the future would wish to satisfy themselves that everything reasonable which could be done had been done in order to make sure that the software used does not have a racial or gender bias.”

Facial Recognition Cameras To Be Used By Police Across London

In a statement after the ruling, Mr Bridges said he was “delighted” the court had found that “facial recognition clearly threatens our rights”. He said: “This technology is an intrusive and discriminatory mass surveillance tool. “For three years now South Wales Police has been using it against hundreds of thousands of us, without our consent and often without our knowledge.

We should all be able to use our public spaces without being subjected to oppressive surveillance.” South Wales Police meanwhile said the test of their “ground-breaking use of this technology” by the courts had been a “welcome and important step in its development” and the force will give the findings “serious attention”. Chief Constable Matt Jukes added: “The Court of Appeal’s judgment helpfully points to a limited number of policy areas that require this attention.

“Our policies have already evolved since the trials in 2017 and 2018 were considered by the courts, and we are now in discussions with the Home Office and Surveillance Camera Commissioner about the further adjustments we should make and any other interventions that are required.”

San Francisco leaders ban facial recognition technology

Mr Bridges, who the force confirmed was not a person of interest and has never been on a watchlist, crowdfunded his legal action and is supported by civil rights organisation Liberty, which is campaigning for a ban on the technology. Megan Goulding, a lawyer for Liberty, said: “This judgment is a major victory in the fight against discriminatory and oppressive facial recognition.” The ruling is likely to mean police forces will have to take into consideration which policies they need to have in place in order to use the technology.

Facial recognition technology is also used by the Metropolitan Police.
