Professional Discipline

Kenneth has substantial and wide ranging experience in professional conduct and competence matters. He has expertise in health care, legal, accountancy and financial aspects of professional discipline. He is a former member of the prosecuting panel of the Bar Standards Board, and since 2017 has been a Legally Qualified Chair at the General Medical Council – Medical Practitioners Tribunal Service. He also sits as a Legal Assessor at the Nursing & Midwifery Council and as a Legal Adviser to the General Dental Council. In recent years he has regularly acted for the General Pharmaceutical Council on appeals to the High Court, the Court of Appeal and the Supreme Court.

He regularly advises or represents solicitors in disciplinary and regulatory cases and appears at hearings before the Solicitors Disciplinary Tribunal and other professional bodies. He was a member of the prosecuting panel of the Bar Standards Board and the General Council of the Bar for over 20 years, and he also represents or advises barristers facing disciplinary issues. In 2014 he was instructed by the Bar Mutual and successfully represented a joint Head of Chambers on appeal before the Visitors concerning responsibilities under the Code of Conduct for the administrative arrangements in chambers. From 2006 – 2012 he was chair of the Appeal Committee for the Chartered Institute of Management Accountants.

Kenneth is the author of the leading textbook Professional Conduct Casebook, published by Oxford University Press. His book, now in its fourth edition, is hugely relied upon by practitioners in this field. It contains all key professional conduct cases in a single portable volume and analyses cases across an extensive range of professions including the healthcare professions, law, accountancy and financial services, the police and prison service, and sports law, and contains well over 1000 cases. He regularly lectures and writes on professional conduct issues and is the joint editor of the Association of Regulatory and Disciplinary Lawyers’ Quarterly Bulletin.

In 2003 Kenneth was appointed by the Home Secretary to conduct a review and report on the legislative provisions in the Police Act 1996 and non-statutory guidance for appointing independent members to police authorities. The review consisted of Kenneth as chair with the Chief Executive of the NHS Appointments Commission and the Chief Executive of Devon and Cornwall Police Authority as specialist advisors. Kenneth’s report, Review of the Selection and Appointments Process of Independent Members of Police Authorities, was presented to Parliament on 4th May 2004, and contained a range of recommendations to improve the appointments process of key posts in police authorities, highlighting the need to engage local people and the importance of police authorities continuing to develop effective links with other community groups.

In 2012 Kenneth chaired a working group of senior practitioners and regulators who submitted a written response on behalf of ARDL to the Law Commission Consultation Paper on the Regulation of Health Care and Social Care Professionals.
