Background
The case of Aina Khan Law Ltd v The Legal Ombudsman & Anr [2025] EWHC 1319 (Admin) concerned a judicial review challenge by the claimant law firm against a decision of the Legal Ombudsman dated 12 February 2024. The Ombudsman had upheld aspects of a complaint made by the Interested Party (IP), requiring the claimant to repay £51,192.60. The central issue was whether the claimant had adequately assessed the IP’s capacity when taking instructions and conducting litigation on her behalf in family proceedings.
The IP had instructed the claimant in September 2020 following the breakdown of her marriage and allegations of child abuse against her husband. The claimant’s attendance notes recorded the IP’s mental health history, including a diagnosis of ADHD and prescribed amphetamines, as well as her distress and allegations of coercive control. Over time, concerns grew about the IP’s capacity, culminating in a psychiatric report by Dr Isaacs in December 2020 confirming she lacked litigation capacity due to a paranoid psychosis. The Ombudsman’s decision criticised the claimant for failing to assess capacity adequately from the outset and for excessive costs.
Costs Issues Before the Court
The court was required to determine whether the Ombudsman’s decision on costs was rational and lawful. The key costs-related issues were:
- Whether the claimant’s failure to assess the IP’s capacity properly rendered the retainer invalid, affecting the recoverability of fees.
- Whether the claimant provided adequate and timely costs updates to the IP, particularly after exceeding initial estimates.
- Whether the Ombudsman’s award of £51,192.60 (comprising a £35,500 refund for poor costs communication and a 20% reduction for the invalid retainer) was disproportionate or irrational.
The Parties’ Positions
Claimant’s Submissions:
The claimant argued that the Ombudsman’s decision was irrational, particularly in conflating mental health issues with a lack of capacity. It contended that the Ombudsman misconstrued Dr Isaacs’ capacity certificate, which did not conclusively state the IP lacked capacity from August 2020. The claimant also challenged the finding that costs updates were inadequate, asserting that informal updates were provided. It further argued the award was disproportionate to the firm’s turnover.
Defendant’s Submissions:
The Ombudsman maintained that its decision was rational and within its broad discretion under the Legal Services Act 2007. It emphasised that the claimant should have conducted a more thorough capacity assessment given the IP’s vulnerabilities. On costs, it defended the finding that the claimant failed to provide timely updates when estimates were exceeded, justifying the £35,500 refund. The 20% reduction was separately justified by the failure to assess capacity properly.
The Court’s Decision
The court held that the Ombudsman’s decision was irrational in part. Key findings included:
- Capacity Assessment: The Ombudsman erred by conflating mental health issues with a lack of capacity and failing to consider the nuanced context of the IP’s instructions. The claimant’s consultations with counsel and the IP’s psychiatrist were reasonable steps to assess capacity. The Ombudsman’s reliance on hindsight (Dr Isaacs’ December 2020 certificate) was flawed.
- Costs Updates: The Ombudsman’s finding that the claimant provided inadequate costs updates was not irrational. The claimant had failed to inform the IP promptly when costs exceeded initial estimates (£43,500 and £75,000).
- Remedy: The court quashed the £15,692.60 award (20% reduction) linked to the flawed capacity finding but upheld the £35,500 refund for poor costs communication.
- Costs of the Claim: The claimant was awarded 40% of its costs (£19,036), reflecting partial success and criticism of its late evidence filing.
The court refused permission to appeal, concluding the Ombudsman’s decision was irrational only in its approach to capacity, not in its broader reasoning on costs.
