Lawyer Rankings(Leading Juniors) Ranked: Tier 1
Blackstone Chambers is ‘the strongest set at the interface of public law and commercial matters’. Numerous members of chambers were involved in R (Miller) v the Prime Minister and Cherry v Advocate General of Scotland, a combined Supreme Court case concerning the 2019 prorogation of Parliament: Lord David Pannick QC and Tom Hickman QC for Gina Miller, James Eadie QC and Lord Keen of Elie QC (a door tenant) for the government in their respective capacities as Treasury Devil and then-Advocate General for Scotland, and for a diverse range of interveners Thomas de la Mare QC, Tom Cleaver, Daniel Cashman and Celia Rooney plus, prior to his appointment to the High Court bench, Michael Fordham QC. At the same level, Sir James was against Dinah Rose QC, Ben Jaffey QC and Cleaver for the appellants in R (Privacy International) v Investigatory Powers Tribunal, which found that an “ouster” clause cannot shield said tribunal from judicial review. In the Court of Appeal, members were instructed on both sides of R (Elan-Cane) v SSHD, concerning Home Office’s refusal to issue a passport with the sex field marked as “X” and also issues of cost capping in judicial review proceedings – Kate Gallafent QC for the claimant, Sir James for the government, and Monica Carss-Frisk QC for Human Rights Watch. As a leading junior, Hanif Mussa successfully represented the government in R (Coughlan) v Minister for the Cabinet Office, defeating a challenge to trials of mandatory voter ID in Braintree.
Blackstone Chambers is ‘a leading public law set which is increasingly present in environmental cases‘, according to one client. Members handle the full range of environmental work, drawing on their skills in public, regulatory, local government, competition, energy, EU, procurement, planning and civil liberties law. A key strand of work has come from the representation of ClientEarth in high-profile matters, including a Supreme Court and European Court of Justice matter concerning air pollution, in which a team including Emma Dixon successfully argued for a declaration that the UK is in breach of EU air quality limits. Juniors Ravi Mehta, who has also represented ClientEarth, and Hanif Mussa, who has represented the Secretary of State for the Environment, Food and Rural Affairs, are also recommended. Clients note that ‘the clerks always seem to be on hand to assist and they are very efficient and personable‘.
Blackstone Chambers is ‘extremely strong in the area of European Union law‘, with members appearing for both business, non-profit bodies, and the UK government in a range of EU-infused cases in London. Members were instructed on both sides of R (Friends of Antique Cultural Treasures) v Secretary of State for the Environment, Food and Rural Affairs, a challenge based on EU free movement of goods law to a near-total ban on the sale of antiques containing elephant ivory; Thomas de la Mare QC acted for the claimant organisation, while Treasury Devil James Eadie QC and Hanif Mussa representing DEFRA. In Luxembourg, Kieron Beal QC and Paul Luckhurst continue to defend the UK government in a case brought by the European Commission concerning an alleged non-collection customs duties applied to transshipments of aluminium through the British Overseas Territory of Anguilla by its authorities. James Segan QC is a 2020 silk appointment.
Blackstone Chambers combines a leading administrative and public law offering with public procurement on which it represents government agencies and ministers and major corporates. James Segan QC has acted for Fujitsu in a case against the Foreign & Commonwealth Office concerning the award of a contract for its ‘global connectivity’ services to another tenderer. Hanif Mussa’s broad practice includes public procurement matters where he is ‘very quick to get to grips with knotty new areas‘. Emily Neill is acting for McAllister Bros Limited, the successful bidder, in a challenge by a disappointed bidder to a significant procurement exercise by Irish Water for pipe cleaning services across Ireland.
Blackstone Chambers joins the ranking this year and is praised as ‘a first-rate set with a great number of talented barristers‘. Skilled in commercial litigation, regulatory, environmental and public law, its members frequently act in high-value matters in highly regulated sectors including the energy industry. Alan Maclean QC‘s broad commercial and public law practice includes numerous energy cases and he recently led Tom Coates in a judicial review by British Gas of Ofgem’s domestic retail energy price cap. He also appeared for the CMA in an appeal brought by against Ofgem by EDF and SSE challenging the charges paid by electricity generators for use of the electricity transmission system. Hanif Mussa and Emily Neill are among the set’s talented juniors, while Tom Coates is a rising star in chambers.
Blackstone Chambers is singled out for its civil liberties practice and is described as the ‘go-to set for human rights issues’. Members are frequently instructed on complex and high-profile matters of national importance covering public law, terror legislation, privacy, and EU law. Recent engagements include Ben Jaffey QC and Paul Luckhurst acting for the claimants in R (Hoareau & Bancoult) v SSFCA pertaining to the right of return of Chagossian people to British Indian Ocean Territory; preeminent silk and ‘Treasury Devil’ James Eadie QC acted for the defendant. Elsewhere, Timothy Otty QC acted in Orozco and Others v Attorney General of Belize, challenging the criminalization of homosexuality in Belize. Other of note include ‘brilliant’ Hanif Mussa who has strength across human rights and international law, and Jason Pobjoy. David Pievsky took silk in 2020. Recently appointed president of Magdalen College, Oxford, Dinah Rose QC remains the distinguished silk in the set along with crossbench peer Lord David Pannick QC. In recent news, Charlotte Kilroy QC joined the set from Doughty Street Chambers.
