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.
‘Without doubt one of the top competition sets’, Blackstone Chambers has members involved in a range of key matters in cartel investigations, merger control and state aid. Brian Kennelly QC and Paul Luckhurst represent UBS in defending a proposed collective proceedings against several banks concerning an alleged foreign exchange cartel. Continuing the payments theme, Kennelly QC, Dinah Rose QC and Jason Pobjoy also represented Visa in the Sainsbury’s v Visa and Mastercard case heard by the Supreme Court in January 2020. Thomas de la Mare QC advised BMW in a damages claim concerning the RoRo shipping investigation, and Kieron Beal QC is representing ITV in a challenge to the European Commission’s decision that the group financing exemption for controlled foreign companies in the UK’s corporation tax system constitutes state aid. James Segan QC was elevated to silk in March 2020.
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 has continued its increasing focus on data protection and freedom of information law mandates with James Eadie QC, Thomas de la Mare QC, Kate Gallafent QC and Ravi Mehta as notable figures contributing to the set’s data work. Mehta’s recent work includes acting for the claimants in Big Brother Watch and ors. v United Kingdom in the European Court of Human Rights challenging the UK’s legislation governing the surveillance of communications.
