His Honour Humphrey LLoyd, QC is an arbitrator and mediator. He is a member of the JAMS Global Engineering and Construction Group and of its Advisory Board. From 1963 until 1993, he was a barrister in England, becoming Queen’s Counsel in 1979 at a relatively early stage, specialising in construction and related law. He has edited The International Construction Law Review, since its foundation in 1984. He acted as advocate and was appointed arbitrator in many domestic and international arbitrations, e.g. Chairman of an Arbitral Tribunal for a dispute about a major highway in a Middle Eastern State; co-arbitrator in a dispute about a freight- handling facility in a French Port; co-arbitrator in a dispute about a U.S. military project in Saudi Arabia. In 1980, he became one of the UK representatives on the Commission on International Arbitration of the International Chamber of Commerce, working on many groups and writing the seminal ICC Report on Construction Industry Arbitrations and a Report on Drafting Awards in international arbitration.

From 1993 until 2005, he was a judge of what is now known as the Technology and Construction Court in London, part of the High Court of Justice. That court deals almost exclusively with construction and other complex disputes, such as contracts relating to computers and computerised systems. During his time on the Bench, His Honour Humphrey LLoyd tried many such cases. He also delivered numerous judgments, including the very first, about the new statutory system of adjudication that applies to most construction contracts in the United Kingdom. He was also one of the few judges then to be selected by parties for appointment as arbitrator for major cases.

In 2005, His Honour Humphrey LLoyd returned to being an arbitrator in international and domestic matters, practising once again from Atkin Chambers, in Gray’s Inn, London. He joined JAMS in 2008.
