Margaret Obi, the Honourable Ms Justice Obi, has become the first African-born person appointed as a High Court Judge in England and Wales. Her elevation marks a milestone in a judicial system that has long faced calls for greater diversity.
She took up her appointment in the King’s Bench Division from October 3 2025, bringing 27 years of legal practice and seven years of judicial experience to one of the most senior courts in the United Kingdom.
Her path to the high bench has been defined by hard work, social commitment and a deep regard for justice. Born and raised in North London to Nigerian parents who arrived in Britain as international students in the 1960s, she attended local state schools before studying law at university. Her parents originally planned to return to Nigeria, but the outbreak of the Biafran war in 1967 persuaded them to remain in the United Kingdom, where they eventually settled and built a life. Obi often describes this family history as a quiet foundation of her public service values.
Her early legal journey was far from smooth. As a young graduate, she sent hundreds of applications for work experience without success. A chance opportunity in the accounts department of a law firm changed everything. It led to work in Crown Courts across London and the South East, then a training contract, and qualification as a solicitor in 1998. She became a partner just four years later.
Criminal defence shaped her early career and her principles. She has spoken passionately about the lawyers who inspired her, praising their belief that everyone, no matter their background or accusation, is entitled to a fair trial. That dedication to fairness has remained constant even as her work expanded into public international law and some of the most complex matters of human rights and war crimes.
Her portfolio career since 2014 has included advisory work for defence teams and international organisations, and several prominent regulatory roles. She has been Deputy Chair of the Financial Conduct Authority decisions committee, the first Service Police Complaints Commissioner, and a House of Lords standards commissioner. In 202,3, she served as an Acting Judge of the Supreme Court of the British Indian Ocean Territory and issued a notable ruling on asylum seekers in Diego Garcia that attracted national attention.
Within the judiciary, she has risen through key appointments as a Deputy High Court Judge, a Deputy Upper Tribunal Judge, and Chair of the Competition Appeal Tribunal. She is now one of only a handful of High Court judges who previously practised as solicitors. That background, she says, gives her a grounded perspective.
‘First, I am a solicitor judge which is relatively uncommon especially on the High Court bench,’ Obi once remarked.
‘What may appear to be worthless experience will turn out to be unbelievably valuable so take the opportunities that come your way. Hard work, determination and resilience will pay off but to be successful in your chosen career path you also need allies, mentors and sponsors as well as a little bit of luck.’
Warm congratulations have poured in from across the legal community. Oba Nsugbe, KC, head of Pump Court Chambers, described her as ‘naturally low key and entirely grounded; never once forgetting her Nigerian roots.’
Richard Atkinson, the outgoing president of the Law Society, praised her elevation as ‘a significant step towards a more inclusive judiciary’ at a time when Black judges make up just 1 per cent of the bench in England and Wales.
This appointment fills a vacancy created by recent elevations and confirmed retirements. It also delivers a profound message of possibility. Her story begins with immigrants who stayed out of necessity, a young woman told no again and again, and a lawyer driven by fairness. It now stands in one of the most respected courts in the country.
Obi arrives not only as a pioneering judge but also as an example to future generations of lawyers who can now see their own journeys reflected more clearly in the system they serve.
