Blackstone Chambers has long been one of the pre-eminent chambers for public international law, particularly in the crossover with public law and  human rights law, as well as related areas of state and diplomatic immunity. Maurice Mendelson QC remains a leading figure in the market, while Timothy Otty QC has built upon his superb reputation for human rights matters and is increasingly active on the investment treaty side.  Several leading juniors are also making strong names for themselves. Paul Luckhurst managed a Supreme Court victory in Janah and Benkharbouche v Secretary of State, a matter concerning National Minimum Wage claims by staff at the Sudanese embassy in London, and is currently pursuing the UK for damages in the European Court of Human Rights. Jason Pobjoy successfully defended the Foreign Secretary’s position on diplomatic immunity in R (Charles) v Secretary of State for Foreign and Commonwealth Affairs, a High Court case concerning the death of motorcyclist Harry Dunn, who was killed in 2019 after he was struck by a car being driven by the wife of an alleged CIA operative.
