In Chambers and Partners 2023 Matthieu is described as “absolutely excellent on his feet, he’s super reliable, very smart and client-friendly. He’s very bright, on top of the detail and can see the bigger picture.” The Legal 500 2023 describe Matthieu as “excellent in his analytical rigour, leaving no stone unturned. He is also a natural advocate.” Matthieu was nominated in the Legal 500 Bar Awards for International Arbitration Junior of the Year 2022.

He will join a number of cross-recruits who joined Essex Court Chambers in recent years including Ben Juratowitch QC, Paul Wee, Sean Aughey, Sophia Hurst, Christopher Lloyd and Alexander Riddiford.

Senior Clerk Joe Ferrigno said “I’m thrilled that Matt’s application to join Chambers was successful and we look forward to him joining us.  Matt is a recognised star practitioner in the field of international and investment treaty arbitration and public international law. Qualified at the New York Bar he will be an invaluable addition to Chambers’ work in that area and more generally.” 

Matthieu says, “I am delighted to be joining Essex Court Chambers, where I look forward to continuing to develop my practice in commercial litigation, international arbitration and public international law. I have worked with and against and appeared before numerous barristers from Essex Court Chambers and I look forward to joining them as a colleague. I will always be extremely grateful for the generous support I have received from colleagues and friends at 4 New Square
