Law360, Expert analysis: A London court delivered its judgment on 25 March 2025 in the recent authorised push payment (APP) fraud case, ruling in favour of Santander in its defence of a claim brought by CCP Graduate School. The High Court found that Santander did not owe CCP any duty of retrieval. The bank did not assume any duty toward third-party victims of fraud, with whom it did not have a contractual relationship. Caroline Greenwell, partner, and Bella Henry, associate, at Charles Russell Speechlys LLP, consider the facts and ultimate decision in Santander before analysing how significant this decision will be for the banking sector and, accordingly, whether it is likely to influence how banks manage their obligations to customers and third parties. Finally, this article will address the mandatory reimbursement requirement (MRR), implemented by the Payment Systems Regulator (PSR) and the Bank of England in October 2024, and how the regime has been faring in its initial months.
