Introduction

Building on the developments of recent years, 2024 has proven to be another significant year for data protection and privacy law in the UK. Over the past year, courts have delivered rulings that not only further clarify the application of key legal principles, such as the “threshold of seriousness” in data breach cases, but also break new ground. Notably, principles usually associated with defamation cases, such as the “single meaning rule” and “repetition rule”, were applied as part of a stand-alone data protection claim for the first time.

As with our previous round-ups in 2021, 2022 and 2023, in this edition we provide an overview of some of the most notable cases from 2024, alongside key takeaways. Such case law is often overlooked in other commentary, which tends instead to focus on regulatory fines, but is important to review in order to understand the wider liability risks in practice.

YSL v. Surrey and Borders Partnership NHS Foundation Trust [2024] EWHC 391 (KB)

This case concerned a former patient (subject to an anonymity order) of an NHS trust who sought damages for the alleged unlawful processing and retention of his personal data.

The patient contended that certain records had been unlawfully shared with his GP, family and school without his knowledge or consent. He also claimed that the records contained inaccuracies, including a potential diagnosis of autism, and that the defendant’s retention policy (whereby medical records were kept for 20 years) was unlawful because it was disproportionate and interfered with his rights under Article 8 of the European Convention on Human Rights.

The court dismissed all claims and held that the aspects of the claim regarding the alleged illegal disclosure of the claimant’s personal information amounted to an abuse of process, owing to a settlement agreement reached between the parties in 2016. The court emphasised that a party cannot pursue a course of action on a matter which they have effectively compromised through a settlement.

The court also clarified that, even if there had not been an abuse of process, the provision of physical and mental health care services by a hospital trust is plainly a function of a public nature exercised in the public interest, and that the NHS trust therefore had a lawful basis for processing the claimant’s sensitive personal data.

It was held that the claimant did not have a right to erasure, as retention was necessary in the area of public health and that the 20-year retention period for mental health records set by the NHS was lawful. In arriving at its decision, the court applied the proportionality test outlined in Bank Mellat v. HM Treasury (No. 2) [2014] AC 700 and determined that a fair balance had been struck between the rights of the individual and the interests of the community. The 20-year retention period resulted from expert consideration, and the NHS should be permitted a “significant margin of discretion” in determining the appropriate period. Additionally, retaining the records was considered in the claimant’s best interests, ensuring access to accurate medical history if further treatment was required. The court also noted that the retention of the claimant’s records was necessary for safeguarding the defendant’s ability to defend itself in potential litigation.

Finally, it is worth noting that the claimant made an application for the judgment to be handed down in private, despite the trial being conducted in public and his identity protected by an anonymity order. However, the court found no valid justification for this, stating that “the Defendant is entitled to a public judgment demonstrating that it did not act unlawfully in the way YSL claimed publicly during the trial, and to the public vindication of its reputation”.
