Stewart specialises in complex and high value international disputes (both in Court and Arbitral forums) and investigations, usually involving allegations of fraud, dishonesty and corruption.



Stewart (who heads the Charles Russell Speechlys Fraud and Investigations Group) specialises in complex and high value international disputes (both in Court and Arbitral forums) and investigations, usually involving allegations across the spectrum of dishonesty including fraud, dishonesty and corruption, with particular emphasis on Financial Services and Energy and Natural Resources. As the vast majority of Stewart's cases involve allegations of fraud, dishonesty and corruption, key legal issues arising include conflicts of law, interim (injunctive) remedies to prevent dissipation of assets and/or preservation of evidence, asset recovery and tracing, as well as contentious insolvency scenarios and investigations.

Stewart’s most recent cases include acting successfully for the liquidators of six defendant companies in the Cayman Islands’ longest-ever trial - 129 days - about one of the world’s largest-ever Ponzi schemes – US$330 billion. Stewart also led a team successfully acting for one of the world’s largest pharmaceutical wholesalers in relation to a complex high-value letter of credit fraud perpetrated on it by a fraudster, and which involved related proceedings in a number of jurisdictions in Europe, the Caribbean and the Pacific. He also has a great deal of experience in advising corporates in relation to product mis-selling within the financial services sector.

Stewart is admitted to practise in England and Wales and has limited admission in the Cayman Islands (in relation to the AHAB vs SAAD litigation). He is also a member of the Fraud Lawyers Association.
