Joseph is a commercial barrister with a busy practice in litigation and arbitration.
He has particular expertise in aviation, insurance, civil fraud and banking alongside general commercial litigation, but is a versatile practitioner able to master the details of industries as complex and varied as mining, fintech and software.
Much of his work is international in nature and raises issues of jurisdiction and/or conflicts of laws, in which he has a particular interest, and he deals frequently with difficult foreign law issues (including, in recent times, Russian, Indian, Israeli, US, French and Mexican law).
Recent instructions include a novel jurisdiction challenge concerned with the interaction between foreign insolvency proceedings and English enforcement proceedings; acting in some of the highest value insurance claims ever brought in the English Courts, arising from alleged losses of aircraft following the Russian invasion of Ukraine; and appearing for the successful claimants in Singapore-seated SIAC and ICC arbitrations of Indian shareholder disputes.
Before coming to the Bar, Joseph studied at Cambridge (where he took a Double Starred First) and at Yale (where he was the Henry Fellow). He has also worked as a full-time Judicial Assistant in the Commercial Court and Chancery Division, assisting Foxton J, Zacaroli J and Bacon J in a range of commercial trials and applications.
