Colin Passmore, a former senior partner at Simmons & Simmons and who currently serves as a Special Adviser to TMI Associates (Head Office: Minato-ku, Tokyo; Managing Partner: Katsuro Tanaka), has been awarded the title of Honorary King’s Counsel, one of the highest honours in the legal profession of England and Wales.
Honorary King’s Counsel is a prestigious distinction conferred on only a select number of individuals who have made outstanding contributions to the development of the legal system of England and Wales. The title is conferred by the King on the recommendation of the Lord Chancellor.
Mr. Passmore played a central role for more than 30 years at the leading UK law firm Simmons & Simmons, with which TMI has maintained a long-standing relationship in the context of its foreign law joint enterprise. He served as Senior Partner of the firm for ten years from 2011 to 2021, making a significant contribution to its growth and development.
In addition to his role as Special Adviser to TMI, Mr. Passmore currently serves as Chair of the City of London Law Society, where he oversees 20 specialist committees that work with government bodies, regulators, and businesses on legislative and regulatory matters. He is also the author of Privilege, a definitive legal practitioner work on legal professional privilege in England and Wales, often cited by the courts.
This award recognises not only his academic contributions to advancing the understanding of legal professional privilege, but also his broad efforts to promote diversity within law firms and the legal profession, to foster a more inclusive legal community, and to support the development of the next generation of legal professionals.
TMI will continue to draw on Mr. Passmore’s extensive experience and insight in enhancing legal services for clients, particularly in Europe and Africa.
