Celia RooneyBlackstone ChambersShe is an exceptionally high-quality junior counsel.

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.
