Roger Masefield QC is “an excellent advocate” who offers “practical advice” on issues arising out of jurisdiction challenges, seizure orders and tracing claims (Who’s Who Legal – UK Bar: Civil Fraud 2019)

Since taking silk, Roger Masefield has been involved in a number of high profile and high value claims in civil fraud, typically on behalf of sovereign clients or Western investors, in the banking, energy and telecoms sectors.

Significant cases include:

• Azima v Dechert & Ors [2023] EWCA Civ 507: Roger Masefield was instructed on behalf of Dechert, seeking to strike out a claim to set aside a judgment alleged to have been procured by fraud on grounds of abuse of process.

• Federal Republic of Nigeria v JP Morgan [2022] EWHC Civ 1447 (Comm): Roger Masefield was instructed in a 7-week trial, on a claim for in excess of $875m against the bank  for breach of a Quincecare duty of care (a duty not to pay out, when on notice of a fraud) – having successfully seen off attempts by the bank to have the claim summarily dismissed, both at first instance and on appeal (Federal Republic of Nigeria v JP Morgan [2019] EWHC 347 (Comm); and Federal Republic of Nigeria v JP Morgan [2019] EWCA Civ 1641)

• PT Ventures v Vidatel [2020] and [2018] BVIHC: Roger Masefield successfully applied to the BVI Court to enforce an arbitral award for c. $650 million against Vidatel, the BVI Company owned by Ms dos Santos (the daughter of the former premier of Angola), arising out of alleged dishonest conduct.  Vidatel sought to resist enforcement, by alleging that the Tribunal had not been properly constituted, having regard to the provisions of the arbitration agreement and French law (as the law of the seat), including the Dutco principle of égalité. Following a week’s trial, and having heard from experts on French arbitration law, the award was upheld and Vidatel’s defence dismissed.  Roger Masefield has previously been instructed successfully to maintain a freezing injunction for $2.1 billion, and striking out an application to have it set aside for misrepresentation as an abuse of process
