Fountain Court Chambers


Rupert is regularly instructed in heavy and high-profile commercial and banking cases, both as part of a larger counsel team and as sole counsel. These cases often have an international dimension and raise complex jurisdictional and choice of law issues. His recent experience includes:

  • representing the Bank of New York Mellon SA/NV at one of the first fully remote Commercial Court trials in proceedings brought by the National Bank of Kazakhstan regarding its entitlement to US$22 billion of custody assets;
  • defending Goldman Sachs International against a US$1.2 billion claim brought by the Libyan Investment Authority in relation to the sale of equity derivatives;
  • important Court of Appeal decisions of considerable market significance on the correct interpretation of standard form ISDA documentation in Deutsche Bank v Netherlands (negative interest on cash collateral posted under the ISDA Credit Support Annex) and Deutsche Bank v Savona (the scope of the ISDA Master Agreement jurisdiction clause);
  • acting for Dexia and Deutsche Bank in English proceedings concerning interest rate swaps entered into by Italian local authorities (including Dexia v Prato in the Court of Appeal); and
  • cases concerning alleged LIBOR misconduct by UK banks.

In addition to his commercial and banking practice, Rupert also has extensive experience in the fields of professional discipline and regulatory law (including, in particular, the law relating to solicitors, accountants, financial services and aviation). His growing professional discipline and regulatory practice has seen him instructed by the SRA, the FRC, the FCA, the CAA and other regulators.

Recent disciplinary tribunal experience includes acting for the SRA in the high profile prosecutions of Mark Lewis and Ryan Beckwith in the Solicitors Disciplinary Tribunal and for the FRC in enforcement proceedings against KPMG in relation to its CASS audits of the Bank of New York Mellon.

Rupert has also appeared in a number of important judicial reviews including R (Lewin) v FRC (in relation to procedural rights of third parties to disciplinary proceedings) and currently R (Donegan) v FSCS (concerning claims for compensation arising out of the collapse of London Capital & Finance).
