Helen Morton

Helen is an experienced lawyer with an established practice spanning the full range of commercial disputes. She acts as both sole and junior counsel and regularly appears in the Business and Property Courts and in arbitration.

Helen is particularly experienced in heavy commercial litigation, civil fraud, private international law, shipping, insurance and data protection. She acts in both the advisory and contentious contexts at all stages of the dispute resolution process, from initial advice to trial and enforcement actions.

She is currently acting in the notable s.69 arbitration appeal, Fimbank Plc v KCH Shipping Co, in which the Commercial Court determined in September 2022 that the Article III Rule 6 time-bar in the Hague-Visby Rules applies to misdelivery of cargo post-discharge. The position was previously undecided with debate in the caselaw, commentaries and international community going both ways. As the point arises frequently across the industry, the decision has considerable commercial significance and is currently being appealed to the Court of Appeal.

Other recent work highlights include acting:

  • For the defendants in US$ 2 billion fraud proceedings (Suppipat & Ors v Nop Narongdej & Ors), a multi-party conspiracy claim concerning the shares of Thailand’s largest renewable energy company;

  • For the claimant in a major class action in relation to largescale data breaches by a global social media platform (SMO (A child) v TikTok); and
  • On behalf of the UK Government in a long running multi-billion pound damages dispute (Bank Mellat v Her Majesty’s Treasury) in which the Court of Appeal issued an important judgment on disclosure where there is an alleged risk of foreign prosecution.

Helen is co-author of the forthcoming edition of ‘The Common Law Jurisprudence of the Conflict of Laws, Hart’ which is due to be published in May 2023. Her chapter, ‘The Mixed Blessing of Vita Food Products: The Impact and Influence of the Privy Council’s Decision’, addresses issues in the conflict of laws and shipping.
