Lalitcumar & Ghedri v Berkshire Healthcare NHS Foundation Trust

James successfully defended the Trust against a claimed £14 million loss by the Claimants. The liability hearing was listed for 4 weeks, with 19 witnesses for the Respondent, requiring all of their evidence to be properly marshalled and put to the Claimants. James cross-examined the Claimants for six days, after which they withdrew all of their claims. These highly complex proceedings involved numerous allegations, multiple causes of actions (including whistle-blowing and disability discrimination) and two separate claimants, needing a different approach to each cross-examination.

Robert Walker v Chief Constable of Cleveland Police

James recently persuaded an Employment Tribunal to widen the ambit of the decision in Tiplady, Court of Appeal, to encompass actions taken by the police as police service rather than as employer. The Claimant, an employee of the Force, had been arrested on suspicion of theft, and contended that it was because he was an employee whistle-blower. James was able to argue that, following Tiplady, this was an act of the Force as a police service, and not as an employer. The Employment Tribunal therefore lacked jurisdiction to hear such a claim. The decision was upheld upon reconsideration.


In this highly confidential matter, James was able to achieve a near-seven figure settlement for his client.

Miss A. de Souza E Souza v Primark Stores Ltd. 2206063/2017

James represented the claimant, who is transgender, in this matter in her successful claims of gender reassignment discrimination and harassment. The case succeeded on almost all counts, was subject to a 25% uplift for ACAS-procedure failures and attracted national & industry media attention. Despite the modest income of the claimant, compensation was awarded in a sum around £49,000.
