Stephen Moriarty has a very broad commercial litigation and advisory practice, with a particular emphasis on banking and financial services, professional negligence disputes, insurance and reinsurance disputes, aviation cases, and international commercial arbitration. . The international nature of his practice frequently involves him dealing with issues of foreign law, which have included, over the years, French, Italian, Greek, Mexican, US, Indian, Indonesian, Egyptian, and Iranian law.

His most recent work includes acting for the successful appellants in the Supreme Court cases of Angove’s v Bailey [2016] 1 WLR 3179 (concerned with the termination of agency, and constructive trusts) and The Commissioners for Her Majesty’s Revenue and Customs v Investment Trust Companies (In Liquidation) [2017] 2 WLR 1200 (a leading case in the law of restitution concerned with the circumstances which an unjust enrichment claim can be asserted against an indirect recipient); and appearing in a nine day hearing before the Court of Appeal in the UBS v Kommunale Wasserwerke Leipzig GMBH proceedings (concerned with the enforceability of a series of single tranche collateralized debt obligations).

As well as acting as counsel in many international commercial arbitrations, he also sits as an arbitrator.
