Noted for being “one of the most methodical barristers I have ever come across”, he is praised for being “unflappable”, for having “an excellent calming manner which is very reassuring to clients”, and for “understanding what arguments will win favour with the court”. He is recognised for his advocacy: his court presentation is described as “excellent”, and “when sat in court you nearly always think you have instructed the superior counsel”.

He is instructed in disputes concerning the international sale of goods, manufacturing and product liability, mergers and acquisitions, joint venture agreements and restructurings, shareholder agreements, distribution and agency agreements, insurance, banking and financial services, construction and engineering, information technology, international transport, shipping, fishing, and professional liability.

Selected Cases

  • Acting for suppliers of construction materials and their insurers in c£3m product liability dispute concerning defective pressure-sensitive adhesive used in joinery fabrication, shop-fitting and general construction works. The adhesive, which had been newly developed with a high solids content, failed prematurely, resulting in extensive delamination. The contractors who had purchased the defective adhesive and who had used it in the course of their businesses claimed against the suppliers for the cost of the associated remedial works, and related losses. On recommendations made by loss adjusters who had been appointed by the suppliers’ insurers, the contractors’ claims were settled. Following these settlements, the suppliers took an assignment of the distributor’s cause of action against the assembler who had containerised the adhesive, and then sued the assembler as assignees to recover the settlement sums and other related costs and losses. The assembler in turn sued the adhesive manufacturer. The two actions were conjoined. Both the assembler and the manufacturer attributed the premature failure to workmanship errors by the contractors, and complained that the settlements were in any event unreasonably generous. They also blamed the failure on defects in the chemistry of the adhesive, for which they blamed each other: the assembler was alleged to have used containers which were contaminated with manufacturing residues, and the manufacturer was alleged to have used insufficient antioxidant and an unusual tackifier. The manufacturer also relied on a limitation of liability clause in its terms and conditions, the reasonableness of which the assembler put in issue under UCTA. Highly complicated materials failure and organic chemistry evidence. Following a trial of several test cases, but before judgment, the assembler discontinued against the manufacturer. Judgment subsequently given for the suppliers: all allegations of workmanship errors were dismissed and all the settlements were found to have been reasonable, both in principle and in amount (DIPT Ltd & Ors v Sanglier Ltd; Sanglier Ltd v Apollo Chemicals Ltd [2023] EWHC 426 (TCC))

On recommendations made by loss adjusters who had been appointed by the suppliers’ insurers, the contractors’ claims were settled. The suppliers then sued the assembler to recover the settlement sums and other related costs and losses. The assembler in turn sued the adhesive manufacturer. The two actions were conjoined. Both the assembler and the manufacturer attributed the premature failure to workmanship errors by the contractors, and to defects in the chemistry of the adhesive.

Highly complicated materials failure and organic chemistry evidence. Following a trial of several test cases, but before judgment, the assembler discontinued against the manufacturer. Judgment subsequently given for the suppliers: all allegations of workmanship errors were dismissed and all the settlements were found to have been reasonable, both in principle and in amount (DIPT Ltd & Ors v Sanglier Ltd; Sanglier Ltd v Apollo Chemicals Ltd [2023] EWHC 426 (TCC)).
  • Acting for registered provider of social housing seeking to enforce its rights against the NHBC under a series of NHBC Buildmark Choice warranties and policies in respect of 50 flats in a multi-storey part-residential and part-office building in London. NHBC had acted as the approved inspector under Part II of the Building Act 1984 in respect of the development. Accordingly, under Part E of the Buildmark Choice warranties and policies, NHBC agreed to pay for repairs where, because of non-compliance with the Building Regulations relating to inter alia fire safety, there was “a present or imminent danger to the physical health and safety of the occupants”. Social housing provider alleged widespread non-compliance with the Building Regulations relating to fire safety, comprising inter alia unsealed penetrations between flats and protected common corridors, unsealed service penetrations between common corridors and common stairs, undersized fire doors, timber panelling with inadequate surface spread of flame rating, unclosed or unsealed cavities, missing cavity barriers, and poorly located electrical service risers. NHBC contested liability, alleging inter alia that there had been late notification, that the defects were within the scope of various exclusions, and that there was in any event no present or imminent danger to the physical health and safety of the occupants.
  • Acting for property developer of part-commercial, part-residential, building destroyed by fire, seeking specific performance of the architect’s obligation to execute collateral warranties in favour of the building’s residential lessees. The terms of the warranties included restrictions on the architect’s liability to the beneficiaries and the architect’s PI policy excluded liability for most claims arising out of a collateral warranty. The spread of the fire was alleged to have been greater than it would have been but for design errors on the part of the architect. The court was required to determine the architect’s PI insurers’ contentions that the architect would be entitled to rely on the contributory negligence of the contractor as a partial defence to any claim under the warranties (Oakapple Homes (Glossop) Ltd v DTR (2009) Ltd (In Liquidation) & Ors [2013] EWHC 2394 (TCC))

Selected Cases

  • Acting for Falkland Islands Government in judicial review proceedings before the Supreme Court of the Falkland Islands defending challenges to decisions by the Principal Immigration Officer, upheld on appeal by the Governor after consultation with Executive Council, to revoke the work permits of the applicants on the grounds that they had each been convicted of sexual offences in the Falkland Islands; issues included whether “minded to revoke” letters should have been sent; adequacy of reasons given both by the Principal Immigration Officer and the Governor on appeal; the extent of the Governor’s discretion and decision-making powers under section 66 of the Falkland Islands Constitution; the proper construction of the relevant statutory provision and the width of the discretion to revoke; the relevance of a related policy concerning the proper evaluation of criminal offences in the context of applications for work permits; and whether the applicants’ constitutional rights to family life under section 9 of the Falkland Islands Constitution were engaged and, if so, whether interference with those rights was proportionate (R (Fowler and Coleman) v Principal Immigration Officer & HE the Governor of the Falkland Islands [2021])
  • Acting for the Government of South Georgia and the South Sandwich Islands in commercial judicial review proceedings before the Supreme Court of the Falkland Islands and then before the Court of Appeal of the Falkland Islands. The applicant, a Falkland Islands company, challenged the decision of the Director of Fisheries to refuse to grant a 4-year commercial fishing licence to a Chilean-flagged vessel which it had chartered. On behalf of the respondent, an application was successfully made to the Supreme Court to have the ex parte grant of permission set aside, on the basis that none of the many grounds of challenge were arguable. The applicant subsequently renewed its application to move for judicial review before the Court of Appeal, where the application was successfully resisted. (R (SGF Ltd) v Director of Fisheries of the Government of South Georgia and the South Sandwich Islands [2019])
  • Acting for Ascension Island Government before the Supreme Court of St Helena and then before the Court of Appeal of St Helena in proceedings brought by the former Chief Executive Officer of AIG, who alleged that he had been unlawfully dismissed by the Administrator. Issues included the availability of injunctive relief against the Crown; the jurisdiction of the Supreme Court of St Helena to grant interim declarations; abuse of process arising from multiple actions; and whether the plaintiff had affirmed his contract of employment and subsequently resigned.
  • Acting for the Government of South Georgia and the South Sandwich Islands in commercial judicial review proceedings before the Supreme Court of the Falkland Islands, in which the applicant challenged the refusal of the Director of Fisheries to grant a licence to its vessel Jacqueline to fish for Patagonian toothfish in the South Georgia and South Sandwich Islands maritime zone for the 2012 season. The vessel had been awarded a licence every year for the past 14 years, except once, when the decision to refuse her a licence was successfully challenged both in the Falkland Islands and in the UK. Issues included whether the applicant had a legitimate expectation of consultation in respect of changes to the licensing policy (including the exclusion of loyalty as a licensing criterion), and whether foreign policy advice given by the Foreign and Commonwealth Office had been misapplied. All the grounds of challenge failed. (R (Quark Fishing Ltd) v Director of Fisheries of the Government of South Georgia and the South Sandwich Islands [2013])
  • Acting for the Government of South Georgia and the South Sandwich Islands in judicial review proceedings before the Supreme Court of the Falkland Islands, and then before the Court of Appeal of the Falkland Islands. The applicant, a Spanish company, challenged the refusal of the Director of Fisheries to grant a licence to their vessel Viking Bay to fish for Patagonian toothfish. Issues included whether the Director had failed to follow his own published policy, whether in reaching his decision he had taken irrelevancies into account, and whether the published policy exhaustively defined the relevant licensing considerations. The applicant abandoned its application shortly before the substantive hearing. (R (Copemar SA & Anr) v Director of Fisheries of the Government of South Georgia and the South Sandwich Islands [2011])
  • Acting for the Government of the Falkland Islands in judicial review proceedings before the Supreme Court of the Falkland Islands. The applicant, a Falkland Islands company, challenged the refusal of the Governor of the Falkland Islands to grant it long term individual transferable quotas in three fisheries. The Governor took the applicant’s track record into account, which was depressed as a result of the loss of a vessel by fire. Issues included whether the Governor had applied his policy in an over-rigid and disproportionately unreasonable manner. The challenge failed. (R (South Atlantic Marine Services Ltd) v Attorney General of the Falkland Islands [2007])
  • Acting for the Government of South Georgia and the South Sandwich Islands in commercial judicial review proceedings before the Supreme Court of the Falkland Islands. The applicant, a Uruguayan company, challenged the refusal of the Director of Fisheries to grant a licence to their vessel Isla Alegranza to fish for Patagonian toothfish. Issues included whether foreign policy advice given by the Foreign and Commonwealth Office had been unlawful, and the non-justiciability of foreign policy matters. The challenge failed. (R (Isla Alegranza SA) v Director of Fisheries of the Government of South Georgia and the South Sandwich Islands [2006])
  • Acting for the Government of St Helena in judicial review proceedings before the St Helena Supreme Court concerning the failure of the Government to determine an application for an immigrant’s landholding licence. Issues included role of ExCo, confidential of ExCo minutes, and ouster of judicial review under St Helena Constitution
  • Acting for the Government of the Falkland Islands in judicial review proceedings before the Falkland Islands Supreme Court. The applicant challenged the lawfulness of an immigration decision taken by the Governor of the Falkland Islands.

  • Acting for the Turks and Caicos Islands Government, representing electoral officials in election petitions before the Turks and Caicos Islands Supreme Court in which the results of the Islands’ 2003 general election were challenged.
