Patrick Dunn-Walsh

Patrick Dunn-Walsh

Call: 2012

Languages: Spanish (proficient)

Patrick has a broad commercial practice in line with Chambers’ profile, with a particular focus on civil fraud/asset recovery, international trade, insurance, company/insolvency and shipping disputes. Patrick also has a particular interest in and experience of cases raising issues of private international law, and has published in this field: [2021] LMCLQ 27, and Ch 10 The Modern Law of Marine Insurance, Volume 5 (co-author).  His advocacy was recently described by Henshaw J as “clear and cogent…, both in writing and at the oral hearing” (The Anna Dorothea [2023] 2 Lloyd’s Rep 446).

He has substantial experience of complex litigation in the High Court and Court of Appeal, and of international arbitration under LCIA, ICC, UNCITRAL, and LMAA Rules, both as sole counsel and as part of a team.

Patrick has extensive experience being led in heavy commercial litigation, often with a civil fraud or offshore angle, and is admitted to the bar of other jurisdictions where appropriate.  He has been granted limited admission to appear for the respondent in the appeal against the judgment of Segal J, sitting as a Justice of the Grand Court of the Cayman Islands, in Jafar v Abraaj Holdings and others [2025] CIGC (FSD) 70, having been instructed as junior for the trial.  The claim is a complex, US$300m fraud and unjust enrichment claim arising out of the well-publicised demise of the Abraaj Group, and the actions of its former CEO, Arif Naqvi.

As sole counsel, he has significant trial and interlocutory experience (including freezing injunctions), and is often instructed to appear against silks.  Recent notable cases include Brightwaters Energy Limited v Eroton Exploration and Production Company Limited [2026] EWHC 296 (Comm), appearing (against a silk) in Fiesta Hotels and Resorts SL & Ors v Deutsche Bank AG & Ors [2024] EWHC 1422 (Comm), and being instructed (against a silk) in a multi-million pound LCIA arbitration arising from a share swap agreement alleged to have been procured by fraud.

Patrick read law at the University of Oxford, graduating with a first class degree and ranked first in the university in contract law. He also studied for the BCL, taking papers in restitution of unjust enrichment, conflict of laws, commercial remedies and corporate insolvency.
