Mathew Gullick is an experienced High Court and appellate advocate.  He has appeared in the High Court, Court of Appeal and the Supreme Court in trials and appeals across the spectrum of his practice, which is focused on public law, employment and commercial matters. He is also frequently instructed both on costs issues and on procedural points across the entire spectrum of civil litigation, including in group litigation.  He undertakes asset forfeiture work (including on human rights issues) in both the criminal and civil jurisdictions, reflecting the crossover between his commercial and public law practice.

Mathew is a member of the Attorney-General's A Panel of Junior Counsel to the Crown in civil matters. Previously he served on the B Panel (2012-2016) and the C Panel (2008-2012).  He is currently instructed by the UK Government in the Kenyan Emergency Group Litigation, in which more than 40,000 individuals have brought claims arising from their experiences during the ‘Mau Mau’ Emergency in the 1950s.

Mathew is also frequently instructed on costs issues across the spectrum of civil litigation. He has been instructed on numerous high value costs matters, including multi-million pound costs claims in group litigation.  He has twice been instructed, as specialist costs Counsel, to make written submissions on costs to the UK Supreme Court.  Mathew's work in this field has included both Queen's Bench and Chancery matters as well as Tribunal proceedings.  In addition to detailed assessment proceedings, his costs practice has, for example, seen him successfully making and opposing applications for protective costs orders in the Administrative Court, and successfully opposing applications for non-party costs orders against legal expenses insurers.

Mathew also has extensive experience of advising and appearing on jurisdictional and procedural issues, including in relation to many of the more obscure provisions of the CPR, the RSC and the CCR. Several of his cases are cited as precedents in the leading textbooks on civil procedure. He has appeared in several contempt of court matters in the High Court. Mathew’s practice also extends to the law relating to the enforcement of judgments, including the powers and liabilities of enforcement officials. He has conducted the oral examination of judgment debtors in the High Court, and has successfully obtained committal orders in linked contempt of court proceedings.

Mathew is an active member of the Bar Pro Bono Unit, and was nominated for the Bar Pro Bono Award in 2007, 2009 and 2011, on the second occasion receiving a special commendation from the judging panel. He was a member of the Gray’s Inn team that won the 2003 Inter-Inn Mooting Competition, and went on the Inn’s biennial mooting tour of the USA in September 2003.
