Roger’s practice as an international arbitrator covers Construction, Engineering, Insurance, re-insurance, Energy, Shipbuilding and Professional Negligence.
In June 2020 he decided to limit the number of new instructions in which he would act as counsel in order to concentrate on work as an arbitrator. During a career spanning over 40 years as an advocate, he appeared as leading counsel in many cases in these areas before trial and appellate courts and arbitral tribunals, including a number of high-value international arbitrations in London, Paris, Geneva, Muscat, Dubai, Qatar, Hong Kong, Singapore, Perth, New York and Washington D.C., and included claims where the amounts at stake were in billions of dollars.
He has vast expertise in the areas of major infrastructure works, Energy (including notable experience in respect of wind farm and Oil & Gas disputes), contracts for the sale of oil, claims related to waste disposal plants and claims relating to contracts for the construction and maintenance of power stations, including, in once case, a combined power station and desalination plant. He has experience of price disputes including price escalation and indexation issues in respect of power and rail projects.
Additionally, his experience covers allegations of negligence against financial service advisors, insurance brokers, underwriting agents, doctors, solicitors, barristers, surveyors and valuers, architects, engineers, quantity surveyors, patent agents, educational psychologists, teachers and others.
