Police use of facial recognition technologies is on the rise across Europe and beyond. Public authorities state that these powerful algorithmic systems could play a major role in assisting to prevent terrorism, reduce crime, and to safeguard vulnerable persons. There is also an international consensus that these systems pose serious risks to the rule of law and several human rights, including the right to private life, as guaranteed under the European Convention on Human Rights (ECHR). The world’s first case examining the legality of a facial recognition system deployed by police, Bridges v South Wales Police, thus remains an important precedent for policymakers, courts, and scholars worldwide. This chapter focusses on the role and influence of the right to private life, as enshrined in Article 8 ECHR, and the relevant case law of the European Court of Human Rights, in the ‘lawfulness’ assessment of the police use of live facial recognition in Bridges. A framework that the Court of Appeal for England and Wales held was ‘not in accordance with the law’ and therefore in breach of Article 8 ECHR. The analysis also considers the emerging policy discourse prompted by Bridges in the United Kingdom surrounding the need for new legislation, a significant shift away from the current AI governance approach of combining new ethical standards with existing law.
