Oliver accepts instructions across the full range of Chambers’ practice areas, including in public, human rights, commercial, employment, procurement, and data protection and information law. He maintains a flexible practice and is equally at home in first-instance tribunals as in the appellate courts. Recent examples of his broad experience include defending injunctions granted against persons unknown, advising on discrimination issues in schools, challenging the award of procurement contracts, assisting in a chancery fraud trial, and advising a large employer on redundancies.

From 2020 to 2021, Oliver was the Judicial Assistant to Lord Burrows at the UK Supreme Court and the Judicial Committee of the Privy Council, working on the most complex and high-profile cases in the UK and from across the Commonwealth. He remains particularly interested in arguments involving difficult points of law, especially on appeal.

Oliver is a strong advocate of pro bono work. He has experience of advising members of the public on human rights issues at Liberty, advocating for the abolition of the death penalty at Reprieve, representing clients in the First-tier Tribunal (Social Security) Chamber through the Free Representation Unit, assisting litigants-in-person at the Personal Support Unit, and volunteering as a caseworker at the Bar Pro Bono Unit.

Before joining the Bar, Oliver was on the civil service fast-stream. He received a first class degree in Natural Sciences from Cambridge University, where he graduated second in the year in his specialist subject and won several scholarships and prizes. He has taught students maths, physics and chemistry and enjoys cases that arise in a technical or scientific context.
