Welcoming Marcus Coates-Walker to 1COR as a new tenant - Apr 2022
Marcus has a specialised practice focussed on clinical negligence, inquest, and personal injury work in addition to being a trained mediator.
Before coming to the Bar, Marcus spent a year as a Director and Trustee of a £7 million turnover company and charity in the Higher Education sector. Before starting pupillage he spent two years as Project Manager of a high-profile independent review at a top-tier commercial law firm in London. During this time he instructed a number of junior barristers, which has given him a thorough understanding of what is required by professional clients.Clinical Negligence
Marcus has a broad clinical negligence practice. He represents both claimants and defendants in cases across a range of medical and dental specialisms.
He is regularly instructed to draft pleadings and to advise on issues of breach of duty, causation, quantum and settlement tactics. He acknowledges the need for practical advice, a hands-on approach to cases and a quick turnaround of paperwork. In conference, he recognises that many clinical negligence cases can involve extremely sensitive issues for both those who have been injured and those who delivered the treatment. He is well-versed at dealing with a range of clients and experts often in difficult cases.
Marcus is very comfortable dealing with complex expert evidence and has a particular interest in cases involving difficult causation arguments and quantum assessments. He is regularly instructed to draft schedules and counter-schedules.
