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 Chairman at the General Medical Council – Medical Practitioners Tribunal Service. He also sits as a Legal Assessor at the Nursing & Midwifery Council and a Legal Advisor to the General Dental Council. In recent years he has regularly acted for the General Pharmaceutical Council on appeals to the High Court. In 2014 he represented the Council in Gulamhusein v GPhC which re-affirmed the test for extension of an interim suspension order in concurrent disciplinary and criminal proceedings, and in 2015 he represented the Council in Rasool v GPhC where the court in reviewing the domestic and European authorities held that there was no risk of impartiality by reason of the chairman having dealt with earlier preliminary issues. In 2017 he represented the Council in the Supreme Court in the case of Khan v General Pharmaceutical Council, and in 2018 in the Court of Appeal in the case of Hussain v General Pharmaceutical Council.

He regularly advises or represents solicitors in disciplinary and regulatory cases and appears at hearings before the Solicitors Disciplinary Tribunal and other professional bodies. In 2017 he successfully represented a solicitor before the SDT on allegations of dishonesty.‘ 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 the responsibilities under the Code of Conduct of the head of chambers for the administrative arrangements in chambers; and the question of costs arising out of the successful appeal. From 2006-2012 he was chairman of the Appeal Committee for the Chartered Institute of Management Accountants. For some years Kenneth has appeared in the Professional Discipline sections of Chambers & Partners and the Legal 500. In 2015 Chambers & Partners referred to his dedication to work, and his exceptional legal knowledge as key factors.  The Legal 500 2016 described him as always incredibly well prepared. Chambers & Partners’ entry for 2017 referred to his “almost unparalleled knowledge of regulatory case law”, and in 2020 as a ” standout practitioner with a breadth of experience encompassing numerous areas of professional regulation.” The Legal 500 for 2020 referred to him as ” A Stalwart fighter”

In 2008 Kenneth spent six months advising the Financial Services Authority on various matters and in 2012 he chaired a working group of senior practitioners and regulators who submitted a written response on behalf of the Association of Regulatory and Disciplinary Lawyers to the Law Commission Consultation Paper on the Regulation of Health Care and Social Care Professionals.

Kenneth is the author of the leading textbook Professional Conduct Casebook, published by the Oxford University Press. His book, now in its third 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.
