Practice Overview

John Martin is an exceptionally experienced and effective advocate in a very wide range of commercial chancery and business disputes. He is adept at leading a team of specialists in complex litigation, whether within or without his own specialties.

He has a particular expertise in contentious trust cases, in company and insolvency matters, in contract disputes of all types (often with a complex technical background) and in tort (particularly the economic torts, having appeared for the successful party in the leading modern House of Lords case on unlawful means conspiracy, HMRC v Total Network [2008] 1 AC 1174).

He deals also with professional liability disputes in these and other commercial chancery areas. His practice is both domestic and international: Overseas, he has dealt with matters originating in Hong Kong, Singapore, the US, Australia, Canada, Russia, Switzerland, Italy, Bermuda, Gibraltar, Netherlands Antilles, Nevis, the Cayman Islands and the Channel Islands among others, and has appeared in the courts of many of these jurisdictions.

He is a (part-time) appeal court judge in Jersey, Guernsey and the Cayman Islands and has been a deputy High Court judge for over 20 years; and he is an experienced arbitrator in international and domestic disputes. He is also a qualified mediator.

John has been consistently recommended in the legal directories, with the most recent Legal 500 2020 edition describing his as “a very experienced silk” and “… has a wealth of experience”.

Chambers & Partners 2019 describes him as “very wise and very sensible, he is good at suppressing the emotion in a case”. They also further state that he is “very forceful in court, he is a good barrister for nasty disputes when the other side is taking potshots”. The Legal 500 2019 edition also says he is “a very experienced Chancery practitioner”.

Previous editions of Chambers & Partners describes his as “authoritative and an absolute star on contentious matters; you always want him on your side in such disputes”. “He is extremely good when appearing at every level of the court system and has a hugely impressive command of the law.”
