Zoe McCallum

'Superb junior, fizzing with brilliant ideas."

Legal 500, 2024
Called: 2016

Zoe practices media, information and public law. Many of her clients are journalists, media organisations, people covered by the press, modern slavery victims, asylum seekers and prisoners.

Zoe acts in defamation, privacy, harassment, data protection and information law actions. Zoe also has a special interest in artificial intelligence and welcomes instructions in that fast-evolving area.

Her unled cases include obtaining injunctive relief on behalf of two journalists at The Times and The Sunday Times in a case against a former source; acting for Times Newspapers Ltd and Telegraph Media Group successfully overturning reporting restrictions; and representing a vulnerable defendant in a harassment and defamation claim arising from her #metoo post about a musician.

As a junior, Zoe was instructed in the Vardy v Rooney “Wagatha Christie” case (led by Hugh Tomlinson KC and Sara Mansoori KC); in the Daedone v BBC litigation (led by Sara Mansoori KC); and a complex breach of confidence claim related to the RAK v Azima litigation (led by Aidan Waterman KC and with Aidan Wills). She often acts for high net worth individuals bringing data claims against financial risk databases.

Zoe draws upon her experience prior to joining the Bar, where she worked in a cross-party political office and was involved in the reform of defamation law, the politics of press regulation and the passage of the Investigatory Powers Act. Alongside litigation, Zoe provides pre-publication advice to national print and broadcast news.

Zoe is listed as a “rising star” in Defamation & Privacy law in the Legal 500.

Zoe frequently represents modern slavery and trafficking survivors in judicial reviews challenging detention, deportation and NRM decisions and is strongly committed to strategic litigation in this area of law.

With Chris Buttler KC, she has acted in key cases challenging government policy, including

  • KTT (ruling that confirmed victims of modern slavery are entitled to leave pending resolution of their asylum claims, upheld in the Court of Appeal).
  • VT & Os (holding that asylum seekers stranded on Diego Garcia are entitled legal aid).
  • KA & Os (breaking the biometrics barrier on behalf of families left behind following UK withdrawal from Afghanistan)
  • DA & Os (bringing an end to a secret Covid asylum screening interview policy which failed trafficking victims)
  • NN and LP (bringing an end to 45-day support limit for confirmed victims of slavery)

Zoe also accepts instructions in asylum, Article 8, deportation and family reunion appeals before the IAT and out of hours applications for injunctive relief.

Zoe is recognised as a “rising star” in Immigration law in the Legal 500.

As well as immigration and trafficking judicial reviews, Zoe’s public law practice includes inquests and public inquiries. Zoe was instructed in the Public Inquiry into Child Sex Abuse, including into the exploitation of children in Catholic schools. She has represented bereaved families at inquests and prisoners at Parole Board hearings. Zoe was also junior counsel in a successful Strasbourg case challenging the compatibility of the Human Rights Act with Article 13 ECHR (SW v United Kingdom [2021] 73 EHRR 18).

Zoe worked in politics and law reform for five years before coming to the Bar. From 2013-2016, she worked in a cross-party political office on issues including the funding of safe abortions for rape victims in armed conflict and reform of investigatory powers and defamation law. In 2012, Zoe worked for an independent commission established by the (then) coalition government to investigate the case for a UK Bill of Rights. From 2010-2011, she worked in New Delhi alongside grassroots disability rights activists, towards a federal bill implementing the UN Convention on the Rights of Persons with Disabilities.

Zoe loves to dance. Away from the Bar, she hikes and swims outdoors and has a long-standing connection to two Pacific islands in Vanuatu. Before moving to London, Zoe worked, travelled and lived for periods in Russia, France, India and the South Pacific. She speaks rusty bislama, rusty french and some hindi.

Zoe has drafted op-eds for the national press (The Times, Guardian, Telegraph), speeches for politicians and written evidence submitted to parliamentary committees.

Zoe worked with Lord Lester of Herne Hill and drafted the first cut of Five Ideas To Fight For: How Our Freedom is Under Threat and Why it Matters (Oneworld, 2016). The book charts the evolution of the legal protections given to the rule of law, human rights, equality, free speech and privacy in the UK; and the ways in which those protections are under threat. It was endorsed by Mary Robinson (former UN Commissioner for Human Rights and President of Ireland), Harold Koh (former legal advisor to President Obama), Sir Sydney Kentridge KC, Baroness Helena Kennedy KC; and positively reviewed, including by Lord Pannick KC in The Times. It was cited by the UK Supreme Court in the majority ruling in PJS v NGN [2016] UKSC 26.

Zoe has a degree in Philosophy, Politics and Economics (PPE) and an MPhil degree in International Relations and was awarded a full departmental scholarship for the duration of graduate study. Her MPhil thesis (for which she was awarded a distinction) concerned the politics of international law on torture and specialist counter-terrorism prisons. Zoe gained a distinction in the Graduate Diploma in Law and was graded ‘Outstanding’ in the Bar Professional Training Course. Lincolns Inn awarded her Hardwicke and Lord Denning scholarships and the Buchanan Prize for exam performance.

Zoe is a member of the Bar Human Rights Committee (BHRC), the Human Rights Lawyers Association (HRLA), the Immigration Law Practitioners Association and JUSTICE.
