Justin Fenwick QC

Call: 1980 QC: 1993



Justin Fenwick specialises in offshore and onshore commercial litigation, with a particular emphasis on fraud cases and claims against professionals arising out of fraudulent transactions. He is regularly instructed in high-profile, high-value cases for his cross-examination skills. Chambers & Partners have variously described him as, The doyen of professional negligence skills, and a man who has few peers in the market”, a force to be reckoned with”, ”great with clients and always calm under fire”, “he’s a star act, who is magnificent in a trial forum”, “his strategic thinking is extraordinary and his grasp of legal principle is a wonder to behold”, “very smooth, unbelievably experienced and has a lovely style in court", "a long-time star in the professional indemnity world and someone to always consider for the most challenging cases." The Legal 500, 2016 recommend Justin for the way in which ‘he can deal with the most combative of benches without pausing for a breath’. He is a top-quality advocate who is calm in a crisis and a clear-thinker, very commercially astute’ and (again) ‘someone always to consider for the most challenging cases. Justin sums up his practice as constantly striving to improve outcomes and to demolish seemingly unanswerable arguments.

Previous experience

Before coming to the Bar, Justin Fenwick spent 10 years in the army, serving in the Grenadier Guards as Platoon Commander, Intelligence Officer, Operations Officer, Adjutant and Company Commander.    His principal functions included intelligence gathering and analysis in Hong Kong, Northern Ireland and West Germany, responsibility as adjutant for the administration and discipline of a battalion of 700 plus, and two years spent as Temporary Equerry and Additional Private Secretary to the Duke of Edinburgh.


Justin Fenwick practises extensively in the Commercial Court in London, in commercial disputes in the Caribbean, Bermuda and Dubai and, mainly in an advisory capacity, in Singapore and Hong Kong and the United States.  He has been admitted for the purpose of conducting a trial in Singapore relating to an insurance dispute over a Jewellers Block Policy and has been admitted as an advocate in BVI, Bermuda, the Cayman Islands and Nevis.  He has been instructed in international commercial arbitrations in the former USSR, the UAE, Kuwait and other jurisdictions.  He specialises in commercial disputes and commercial dispute resolution and insolvency situations.

He has extensive experience of commercial arbitration including international arbitration and is familiar with ICC and LCIA procedures.  He regularly acts as arbitrator in commercial and insurance disputes. He has acted for and against governments including the Hong Kong government and the Chinese government as well as extensive and varied work on behalf of the UK government.    His arbitration work has included international contractual disputes, international sports tournament franchise contracts, new highways in Turkey, pipelines in Kuwait, housing developments in Hong Kong and shipping disputes in the Far East.

He has acted for one of the Big 4 accountancy firms in a dispute against the Dubai Financial Services Authority in The Financial Markets Tribunal, DIFC-LCIA.

He is currently acting for another Big 4 accountancy firm, leading a team of 3 QCs and several juniors in the Defence of a £1.6billion audit claim in relation to the collapse of a tertiary lender through management fraud.

He is also acting for a major accountancy firm in the defence of an $700 million audit fraud claim brought in Cayman in relation to a Cayman based hedge fund.

He is also currently advising the Liquidator of Stanford Bank in Antigua in relation to proceedings in various jurisdictions.

He has recently acted for a Brazilian liquidator in recovering substantial assets in the Cayman Islands and elsewhere in the Caribbean.

He is currently involved in several claims in BVI relating to alleged fraudulent dissipation of assets emanating from the Russian Federation and Ukraine. He has advised on and acted in a case involving consideration of the Nevis law of secret trusts (NIETO) which was heard in camera in the BVI Commercial Court and the Court of Appeal of the Eastern Caribbean.

In the insurance field, he has frequently acted as Counsel in coverage arbitrations involving scope of cover, aggregation, avoidance and dishonesty and other exclusions. He has regularly acted as arbitrator with and without oral hearings in coverage matters including notification disputes, disputes between insurers, non-disclosure and aggregation issues, where the underlying policy is professional liability cover (solicitors, surveyors, financial intermediaries, product liability cover, jewellers block and Contractors All Risk cover).

He has advised extensively in relation to partnership disputes and to disputes involving Limited Liability Partnerships and minority shareholder claims..

A substantial part of his work, both in trial and in an advisory capacity, has been in relation to property litigation and property related matters.  In addition to acting in very large numbers of mortgage lending claims against professionals, in particular valuers and solicitors, he has been involved in extensive litigation in relation to mortgage indemnity policies and their construction.  He has acted for solicitors in relation to partial equity schemes including ‘50/50’ schemes and other forms of shared ownership.  He acted for several hundred solicitors in relation to the Equity Release and Home Investment Plan claims brought by the Investors’ Compensation Scheme against building societies and solicitors.  He was involved in the Etridge litigation in respect of undue influence claims.  He has also acted in key mortgage-related claims such as Bradford & Bingley v Rashid & Ashe v Natwest  in the House of Lords and Court of Appeal respectively, where the courts clarified the applicability of the Limitation Acts to the rights of mortgagees. He is awaiting judgment from the Supreme Court in a landmark case involving the rights of mortgagees in sale and leaseback transactions.

He has acted regularly in relation to insolvency matters, including those affecting insolvent banks, both in the UK and in offshore jurisdictions.  He has advised in a number of cases involving failed hedge funds and investment .plans in the UK, the Cayman Islands and the USA. He has considerable experience in asset-tracing, particularly tracing assets misappropriated fraudulently, including acting for liquidators in the Caribbean, Brazil and Canada.  He has acted in relation to numerous freezing orders in the UK and foreign jurisdictions.

Justin Fenwick has played a key role in the development of group litigation in England and Wales.  Having had some limited involvement in the Pertussis (Whooping Cough) vaccination litigation in the early 1980s (acting first for the Secretary of State for Health and Committee on Safety in Medicines and then for various medical experts summoned as witnesses), he witnessed the collapse of the first phase of that litigation because of the inadequacies of the test case approach adopted.  As a result, in the Opren litigation in which he again acted for the Government, he was instrumental in developing the approach to group litigation with lead cases and costs sharing orders which has since become the model for GLOs.  After the Government’s successful defence of that litigation, he has become involved in a wide range of group actions, principally in the field of product liability (in particular, tobacco, HIV haemophiliac litigation, CJD human growth litigation and BSE litigation) but also in a range of other fields including group actions against solicitors (Investors Compensation Scheme litigation, Paragon Finance litigation and most recently The Accident Group litigation), tax schemes (Container Leasing, Film Finance and Technology Investment Schemes in particular), and disaster litigation (Buncefield oil explosion at Hatfield by way of example).

He has practised extensively in most areas of product liability, commercial litigation and related fields, with a particular emphasis on cases involving technical and scientific issues, commercial fraud, complex financial accountancy and taxation issues.  He is particularly experienced in the analysis of contractual issues, including insurance contracts, share sale agreements, development and construction agreements. 

He specialises in the cross-examination of witnesses, both factual and technical, in areas varying from specialist scientific subjects such as pharmaceuticals, chemicals and materials and engineering issues, to financial, accountancy and taxation issues.

A key element of his work for defendants in litigation is the analysis of causation issues.  This includes issues of epidemiology, statistical probability and causation in fact and was a central element of his preparation work for the human growth hormone and Variant CJD litigation.  He spent many months learning about the relative risk of cancer from different activities and problems of causation of cancer when acting for Gallaher, one of the principal Defendants in the tobacco litigation.  This work also involves issues of scope of duty and remoteness of damage, particularly in relation to future economic loss.

He is accustomed to dealing with cases involving very large numbers of documents and is familiar with most document management technology systems as well as the use of spreadsheets and databases. 

Many of his cases involve careful analysis of accounts, taxation issues, the detection of fraud and exaggerated claims, and the calculation of economic loss. 

He has wide experience in dealing with issues of limitation and successfully brought to an end the Tobacco Litigation in the 1990s following success on a preliminary issue of limitation in a number of  lead cases.

He has consistently been rated by Chambers and the Legal 500 in the fields of product liability and professional negligence. He is also rated by the Legal 500 in the field of civil fraud, insurance and reinsurance and by Chambers in commercial dispute resolution and construction. Comments include the following:-
