Practice Summary

Andrew has extensive experience of complex and high-value commercial litigation and international arbitration, both led and unled. Andrew’s practice involves a wide range of commercial disputes and advisory work, with a particular focus on civil fraud, banking and finance, energy and natural resources and unjust enrichment and restitution. Andrew has considerable advocacy experience in litigation and arbitration, including appearing as sole counsel for the defendant in a 10-day Commercial Court fraud trial (Exxon Chemical Limited v Norbert Dentressangle).

In 2017, Andrew was named as one of Legal Week's ‘Stars at the Bar', which profiles the most promising junior barristers in the UK. Legal Week described Andrew as ‘An expert in unjust enrichment’ and ‘user-friendly and excellent value for money’. A partner at one City firm told Legal Week that Andrew has ‘the magic combination of top class legal abilities, remarkable diligence, a commercial approach and a charming temperament. He is a real delight to work with; a team player; and genuinely a star’. Another commented that ‘Andrew is the complete package’.

Prior to transferring to the English Bar (2012), Andrew trained with the State Solicitor’s Office of Western Australia, taught private law at the University of Oxford and practised in New York and London as an associate at Shearman & Sterling LLP. Since then, he has gained a wide range of experience, appearing in his own right in the Court of Appeal, High Court and LCIA and UNCITRAL proceedings, as well as being led in substantial, complex and high-value litigation and international commercial arbitration in England and jurisdictions around the world, including New York, Singapore, Nigeria, the Isle of Man and Israel. Andrew has also acted as an expert witness on English law in foreign proceedings on a number of occasions.

Andrew has a particular interest in unjust enrichment and restitution, which was the subject of his doctorate. He is the Consulting Editor of the Restitution title in Halsbury’s Laws of England and the author of a leading text on enrichment (Enrichment in the Law of Unjust Enrichment and Restitution, Oxford, Hart, 2012) that has been cited with approval in the Supreme Court. 

Andrew is called to the Bar in the state of New York and is able to advise on issues of New York law.
