Back to Our People


Jon has acted on behalf of employers and employees in employment disputes involving doctors, dentists and other healthcare employees up to and including Chief Executive level.  He has significant experience of disputes between general medical and dental  practitioners on the one hand and Primary Care Trusts on the other, which have some of the features of employment disputes.

His biggest strength is his eye for detail; he’s incredibly thorough and never misses a thing.”

Experience & Expertise

Jon has maintained an interest in employment law throughout his career.  The great majority of his employment cases are in the police and healthcare fields.

As a result of his experience in clinical negligence and the evaluation of medical expert evidence he was involved at an early stage in cases brought under the Disability Discrimination Act 1995 from shortly after the coming into force of that legislation, in particular relating to what amounted to a clinically well-recognised psychiatric illness for the purposes of the Act.

For many years he has acted for police forces (Chief Constables) in cases in which unlawful discrimination, including sexual and racial harassment, has been alleged.  By way of illustration he successfully defended a claim in which a police officer who became blind alleged that his force had discriminated against him on the ground of his disability in requiring him to resign and moving him to a police staff role.

Jon has particular experience of police pensions. He has been instructed in a series of Administrative Court cases principally involving the application of the statutory criteria for entitlement to a police injury on duty award and the procedure under the relevant regulations under which entitlement to such an award is determined, first by the selected medical practitioner and on appeal by the Police Medical Appeal Board.

Following the decision in Kulkarni, Jon has appeared in several cases on behalf of the practitioner at internal disciplinary hearings, including in cases in which internal disciplinary process has been followed by fitness to practise hearings at the GMC.  In some of these it has been necessary to consider and apply the growing body of case law governing the issue of injunctions against healthcare Trusts compelling them to follow the terms and requirements of their own internal disciplinary procedures.
