Notable recent cases include:

Federal Republic of Nigeria v JPMorgan Chase Bank NA [2022] EWHC 1447 (Comm)

Acting (with Rosalind Phelps KC and David Murray) for the successful defendant in a high-profile $1.5 billion+ claim for breach of Quincecare duty. The background to the claim was an alleged “fraudulent and corrupt scheme” perpetrated by former government ministers, concerning the proceeds of an oil prospecting licence. The judgment of Cockerill J, following a seven-week trial, contains a valuable discussion of the nature of the Quincecare duty, the meaning of gross negligence in private law, and the scope of the Foreign Act of State doctrine.

FTAI AirOpCo UK Ltd v Olympus Airways SA [2022] EWHC 1362 (Comm)

Acting (as sole counsel) for the successful claimant in a $5 million+ aviation claim in the London Circuit Commercial Court. The claimant lessor was awarded unpaid rent, various costs and expenses incurred in the recovery of the aircraft, and damages for the aircraft’s diminution in value. The claim gave rise to questions of interpretation of a standard commercial aircraft lease, including the provisions on termination, indemnitees, and relief. It also involved disputed issues of fact as to the condition and return of the Aircraft, and expert evidence as to valuation. Aaron also acted as sole counsel at the CCMC, DGH, and two full-day application hearings (including FTAI AirOpCo UK Limited v Olympus Airways [2021] EWHC 2614 (Ch)).

Tai Mo Shan Limited v Persons Unknown [2024] EWHC 1514 (Comm); [2024] EWHC 2532 (Comm)

Acting (with Nik Yeo) for the claimant high-frequency trading firm, in respect of a hack of crypto assets valued at $450 million+. The case involved several hearings in two related sets of proceedings, including obtaining injunctive relief against an algorithmic trading platform (a non-cause-of-action defendant) to bring about the seizure and detention of the assets, and obtaining permission to serve a claim for the recognition and enforcement of a foreign judgment against unidentified hacker out of the jurisdiction and by NFT (a first-of-its-kind application).
