Intellectual property specialist Justice Birss named as next Master of the Rolls and head of civil justice in England and Wales
Intellectual property specialist Justice Colin Birss has been named as the next Master of the Rolls and will succeed Geoffrey Vos as head of civil justice in England and Wales when Vos retires on 31 October 2026. The Master of the Rolls is the second most senior judge in the English civil courts, presiding over the Court of Appeal (Civil Division) and carrying responsibility for the administration of the civil justice system, including case management reforms, access to justice policy, and the development of procedural rules. Justice Birss is known within the legal profession for a deep expertise in intellectual property and technology-related litigation, having presided over significant patent and copyright disputes during his career in the lower courts. His appointment to the most senior civil leadership position carries particular significance at a moment when English courts are navigating a growing caseload of technology, AI, and data-related disputes that require judges with technical legal literacy. The transition follows Geoffrey Vos, who championed digital justice reform during his tenure.
Why this matters
The appointment of Justice Birss, an IP and technology litigation specialist, to lead England and Wales's civil justice system is a signal about the direction of judicial leadership at a time when the courts are under pressure to handle an expanding caseload of technology, platform liability, and AI-related disputes. His background suggests that procedural and jurisprudential development in the Court of Appeal may be shaped by a judge with direct experience of technical evidence and complex multi-party IP litigation. For litigators, a new Master of the Rolls also means potential changes in case management guidance, appeals practice directions, and civil procedure priorities. The appointment activates no specific deal work, but it is a development every disputes practitioner targeting City firms should be aware of.
On the Ground
A trainee in a disputes team would note this appointment when preparing chronologies or skeleton argument research in Court of Appeal cases, as judicial preferences and procedural tendencies of the presiding judge are material to advocacy strategy. They would also assist with court filing and service of any applications timed around the transition period.
