Nick Chapman KC
Nick Chapman KC has a litigation and advisory practice focusing mainly on public and regulatory law, public inquiries and inquests.
Nick is consistently ranked as one of the country’s leading barristers across his practice areas. The main independent legal directories have described him as “a class act”, “incredibly impressive”, “an outstanding advocate” and “an exceptional team leader” who is “unflappable”, “completely charming” and “a pleasure to work with”. He regularly draws praise for his judgement, tactical and strategic acumen, pragmatism, efficiency, work ethic and intellect, and for his expertise as a leader of large legal teams.
Nick’s cases are generally nationally high-profile and regularly raise cutting edge issues. He has appeared at every level of the domestic court, tribunal and coronial system, from the magistrates and First-tier Tribunal to the Supreme Court. He has acted in scores of reported cases and has been successful in every case in which he has appeared before the Court of Appeal or Supreme Court.
Nick regularly leads large teams of lawyers including, currently, as leading counsel representing the UK Government in the Post Office Inquiry (for DBT), Phase 1 of the Southport Inquiry (for DfE) and Module 9 of the UK Covid-19 Inquiry (for Cabinet Office / No.10). His clients have included Prime Ministers and other senior politicians, Government departments, agencies and arm’s length bodies, the UK’s Security and Intelligence services, multinational corporations, national sports bodies, third sector organisations, and Magic Circle and other leading firms of solicitors.
Before taking silk, Nick was a member of the Attorney General’s A panel of counsel for 6 years (and the B and C panels before that), during which time he represented the UK Government in some of its most important and contentious litigation. He also served on the Equality and Human Rights Commission’s A panel for 5 years, amongst several other appointments.
Recent case highlights include:
Please see the Expertise section below for further details of Nick’s practice.
Nick is consistently rated as one of the country’s leading public law practitioners, acting in the many of the most complex, important and high-profile cases in the field.
His practice covers the full range of public and regulatory law matters, including (by way of example) human rights and civil liberties, constitutional law, national security and counter-terrorism, public procurement, infrastructure, criminal justice and penal law, retained EU law, public international law, tax, nationality, immigration and asylum law, and professional discipline.
His cases are regularly at the cutting edge of the law, and he has appeared in scores of reported cases and at all levels up to and including the Supreme Court. He has an unusually high success rate at first instance, and has never lost a case in the Court of Appeal or Supreme Court.
Before taking silk, Nick was one of only a handful of members of both the Attorney General’s “A panel” of counsel and of the Equality and Human Rights Commission’s “A panel” of counsel.
R (MCML Ltd & Foster) v HMRC & Southwark Crown Court
Judicial review claim brought by a City firm and its former head of equity finance trading.
The claimants challenged search warrants obtained and executed by HMRC following requests from Denmark and Germany, in connection with investigations into suspected Cum-Ex fraud totalling £1/2 billion. They advanced 8 grounds of challenge, including alleged non-disclosure when applying for the warrants.
Following a 3-day hearing, the Divisional Court refused the claim on all grounds. It certified two points of law of general public importance, relating to the duty of full and frank disclosure in cross-border cases. The Supreme Court refused permission to appeal. Nick led for HMRC.

It also indicated that it was lawful to detain individuals to obtain their details and pass them on to the NHS. The policy was withdrawn shortly before the hearing.
Mr Justice Chamberlain held that the Home Secretary had also breached her duty to consider the impact of the policy on the groups protected under the Equality Act 2010, including women, who are known to be disproportionately impacted by NHS charging.
R (CX1-CX8) v Secretaries of State for Defence and for the Home Department
