James practices in three core areas: product liability and group actions; the law of the workplace, including employment and health & safety; and general commercial work.
His recent experience includes: appearing for the worker as sole counsel in the Court of Appeal and ECJ in an ongoing dispute over payments in lieu on termination for unpaid holiday pay; being instructed by the defendant Jersey funds in an arbitration under LCIA rules, involving allegations of commercial fraud bank by the claimant in Germany and Luxembourg; and acting for Cape in a major High Court trial, resisting contribution claims by insurers towards mesothelioma payouts, followed by ongoing litigation over access by a third party to documents used at the trial.
After qualifying as a solicitor in 2008, James spent two years as an associate in the corporate group at Slaughter and May. He was then a judicial assistant at the Court of Appeal in 2010, where he assisted Arden LJ. He is committed to giving practical advice and resolving disputes as quickly and cost-effectively as possible.
James read history at Christ’s College, Cambridge, where he was a choral scholar and Levy-Plumb scholar. He graduated with a First in 2003 before taking the GDL and LPC at BPP Law School in London. He is Chairman of the Holst Singers and was a TA soldier from 2004 until 2008. James will consider accepting pro bono instructions, particularly in employment disputes.
Product Liability & Group Actions
James was part of the team acting for the defendant in Concept 70 v Cape Intermediate Holdings, led by Justin Fenwick QC, Geraint Webb QC and Andrew Kinnier. The case concerned liabilities for historic asbestos exposure: the former employers of workers suffering from mesothelioma sought (through their insurers) a contribution from Cape under the Civil Liability (Contribution) Act 1978 towards settlement sums paid out. The case settled after the conclusion of a six-week trial in the Queen’s Bench Division in February 2017. James is also instructed in the ongoing litigation over non-party access to documents used at the trial which reached the Court of Appeal in the summer of 2018.
Also in the field of industrial disease, James is currently instructed as junior by the Department of Business, Energy and Industrial Strategy (as successor to the liabilities of the National Coal Board) in the British Coal Coke Oven Workers Litigation under a GLO.
James was instructed by Smith & Nephew, the medical equipment manufacturers, in the early stages of the recent metal-on-metal hip replacement litigation.
In individual product liability matters James was led by Geraint Webb QC acting for Bednest Ltd following the death of a baby in a bedside sleeper in April 2015; and for BMW in relation to the death of Narayan Gurung following an accident involving a BMW 3 Series. He has also acted on a range of smaller disputes over allegedly defective goods including domestic appliances, fertilizers and vehicle components.
As a C Panellist, James has also been involved several multi-claimant actions for the Ministry of Defence, including the Q Fever, Noise-Induced Hearing Loss and Non-Freezing Cold Injury litigation. He also assisted with some of the complex costs issues arising out of the GLO following the dismissal of the claim by the British Nuclear Test Veterans in the Supreme Court.

Company, Commercial & Insolvency
James has a broad and growing commercial practice. He was recently instructed by a Jersey-based fund in a major arbitration under LCIA Rules over its refusal to pay out to an investor associated with various alleged frauds in different European jurisdictions.
His background as a City solicitor enables James to advise on all aspects of company law. Whilst an associate at Slaughter and May he worked in the corporate / insurance group on a range of transactions, including the creation of the Asset Protection Scheme by HM Treasury to deal with the UK banking crisis in 2009, and Prudential PLC’s proposed rights issue and $36bn bid in 2010 for the AIA insurance group. He also gained experience of commercial agreements, regulatory, outsourcing, insurance and IT issues.
Between 2014 and 2016 James undertook a part-time secondment at HSBC, assisting with the FCA-led Review of mis-sold interest-rate hedging products and the assessment of consequential loss claims by HSBC customers.

James has wide experience of all aspects of statutory employment work including employment status, unfair dismissal, TUPE, discrimination, redundancy and whistleblowing. He appears frequently in the Employment Tribunal and EAT.
James has a particular interest in working time and is currently instructed as sole counsel on perhaps the most significant case on holiday pay to reach the ECJ in the last few years: King v Sash Window Workshop Ltd C-214/16. James has acted for Mr King throughout in a case concerned primarily with the entitlement to payments in lieu on termination under the Working Time Regulations 1998. The case is particularly relevant in cases where the worker (like Mr King) has been miscategorised during the employment relationship and not paid any holiday pay. The outcome will be of great importance to the balance between employers and workers in the developing gig economy.
James is also regularly instructed in common-law employment disputes and injunction applications involving employee competition, confidential information, wrongful dismissal and restrictive covenants. He advises both employees and employers.
Helped by his experience in group actions involving personal injury, James is also familiar with the law of employer’s liability and workplace injury claims.
- Advising an employee of a recruitment company threatened with an injunction for breach of restrictive covenants in simultaneous High Court and Employment Tribunal proceedings.
