LENZEN ADR

John regularly serves as an arbitrator in international commercial disputes, including as sole or Chair/third arbitrator, and has authored numerous Final Awards. He has also had direct responsibility for the hands-on management of many international and multi-jurisdictional arbitrations in Bermuda, England and the United States. At least twenty of these proceeded to an Award on the merits, and the vast majority were disputes over at least $100 million. Almost all of these arbitrations involved a multiplicity of arguably applicable procedural and substantive laws, and many also entailed competing litigations as to predicate jurisdictional issues. Indeed, some required parallel or even subsequent challenges to the arbitral process itself, including the seminal Halliburton v Chubb [2020] UKSC 48, which was ultimately resolved by the Supreme Court of the United Kingdom.
