This litigation included two very substantial Commercial Court actions involving claims of dishonest assistance and breach of fiduciary duty against one of Sumitomo’s London Metal Exchange brokers.
  • Sibir Energy v Abramovich - acting for the claimant in a joint venture dispute relating to rights to an oil field worth over USD $2 billion, after the claimant’s interest had been diluted from 50% to less than 1%. The claims were for breach of fiduciary duty and in knowing receipt.

  • Acting for a leading provider of energy and environmental solutions in the trial of its breach of confidence claim against a global financial institution, which arose out of a corporate finance deal involving carbon credits trading. My client was awarded the largest damages award in a breach of confidence claim to date at the time.
  • Defended one of the world’s largest accountancy firms against a professional negligence claim for £25m brought by the claimant, which had purchased a chain of fitness clubs and later alleged that my client had been negligent in carrying out financial and commercial due diligence work for them relating to the purchase.
