Legal Expertise

Clinical Negligence

Simeon is recognised as one of the country’s leading clinical negligence silks and is a Chambers and Partners star individual. He is commended for the relationships he builds with his lay and professional clients, his ability to absorb and distil large quantities of complex and technical medical information and for his cross-examination skills. His persuasiveness in Court has been noted by judges on numerous occasions. Solicitors comment on his approachability and informal style and lay clients on his manner and ability to explain complex issues. He is regularly instructed to act in cases emanating from international jurisdictions.

Notable Clinical Negligence cases

Joseph John v North West Regional Health Authority (2022) High Court Trinidad & Tobago

Simeon acted for the defendant in this clinical negligence case in the County Court and the High Court of Trinidad & Tobago, and won. This was a multi-million mismanagement of birth case, where there is an active application for appeal.

Khan v Meadows [2021] UKSC 21

Simeon acted successfully for the respondent, in this appeal against the applicability of the scope of duty principle in clinical negligence torts. Omodole Meadows sought to establish Dr. Khan’s liability for the costs associated with her son’s autism. The Supreme Court identified six sequential questions to clarify the role of the scope of duty principle (a defendant is liable only for losses which fall within the scope of their duty of care to the claimant) in the context of the tort of negligence (paragraph 28, judgment). It found no basis for excluding clinical negligence from the scope of duty principle, nor for confining the principle to cases involving pure economic loss arising in commercial transactions.

He has unparalleled experience in medical product and pharmaceutical group actions and assisted in the successful negotiation of a settlement in the metal on metal hip litigation, leading a team of four counsel.
