Mathew Gullick is an experienced High Court and appellate advocate. He is a member of the Attorney-General's A Panel of Junior Counsel to the Crown in civil matters. He has appeared in more than 30 substantive appeals in the Court of Appeal and the UK Supreme Court, the majority of them as sole or lead advocate. His practice is focused on public law and employment matters but 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, and is a contributor to one of the leading practitioner textbooks in the field. As well as appearing in Courts and Tribunals, he also acts as a representative in mediations.
From July 2015 to November 2018, Mathew was part of the Counsel team instructed by the UK Government in the Kenyan Emergency Group Litigation (KEGL), in which more than 40,000 individuals unsuccessfully brought claims in the High Court arising from their experiences during the ‘Mau Mau’ Emergency in the 1950s. The KEGL was one of the longest-running trials in English legal history, sitting in court for 230 days between the start of the trial in May 2016 and its conclusion in November 2018. The case involved wide-ranging and complex issues including in relation to jurisdiction, limitation, constitutional law, tort (negligence, vicarious liability and common design), evidence and civil procedure.
From January to December 2020, Mathew was instructed by Ofsted on several of the Investigations conducted by the Independent Inquiry into Child Sexual Abuse (IICSA), including those into Child Sexual Exploitation by Organised Networks and into Effective Leadership of Child Protection in which Ofsted was a Core Participant.
In the public law field, Mathew is regularly instructed to appear in the Court of Appeal, the Administrative Court and the Upper Tribunal in immigration matters and also acts in prison law and social security benefits cases. In the employment context, he acts for both claimants and respondents (public, private and third sector) across the range of employment law including unfair dismissal, wrongful dismissal, all types of discrimination, equal pay and unlawful deductions from wages (including the non-payment of bonuses).
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 post-judgment written submissions on costs to the UK Supreme Court and has also conducted two multi-day detailed assessments of costs in 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 procedural legislation and rules. Several of his cases are cited as precedents in the leading textbooks on civil procedure. 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 has been nominated for the Bar Pro Bono Award three times, on the second occasion receiving a special commendation from the judging panel.

Mathew Gullick accepts instructions in a wide range of public law matters. He was appointed to the Attorney-General's A Panel of Junior Counsel to the Crown in civil matters in September 2016, after eight years on the B and C Panels.
In the immigration field, Mathew is regularly instructed to appear in the Court of Appeal, the Administrative Court and the Upper Tribunal, and has been involved in numerous unlawful detention claims and deportation appeals. He has extensive experience of Points-Based System cases, having been instructed on several major appeals relating to the Post-Study Work route and its closure in April 2012. He undertakes both claimant and defendant work.
Indicative immigration law cases are:
R (on the application of Idira) v Secretary of State for the Home Department  EWCA Civ 1187,  1 WLR 1694 - detention in prison, under immigration powers, of time-served foreign national offender pending his deportation did not breach Article 5 ECHR.

Mathew has also appeared for the Justice Secretary in prison law challenges and in cases involving challenges to refusals of applications for compensation for miscarriages of justice under the statutory scheme in the Criminal Justice Act 1988.
Notable cases include:
R (on the applications of Nealon and Hallam) v Secretary of State for Justice  UKSC 2,  2 WLR 440 - Article 6.2 ECHR not applicable to decisions to refuse award under statutory compensation scheme for miscarriages of justice; scheme would not breach Article 6.2 even if applicable.

R (on the application of Hussain) v Secretary of State for Justice  EWHC 1452 (Admin),  ACD 117 - Category A prisoner not entitled to an oral hearing of his annual categorisation review; request for an oral hearing should have been made before the review was undertaken, not afterwards.
R (on the application of Adetoro) v Secretary of State for Justice  EWHC 2576 (Admin),  ACD 16 - lawfulness of decision to revoke earlier decision accepting Parole Board recommendation for move of Category A prisoner to open conditions.
In Secretary of State for Work and Pensions v Cattrell  EWCA Civ 572, Mathew acted for the successful respondent in an appeal by the Secretary of State arising from the acceptance by the First-Tier and Upper Tribunals that there was no work that would be reliably safe for her as a result of a severe allergy, so that she was entitled to incapacity benefit. He has also advised on other benefit-related appeals and judicial review proceedings, and has appeared (for the successful appellant) in the Upper Tribunal (Administrative Appeals Chamber) in a rare oral hearing of an appeal.
Another area of interest is all aspects of the law relating to elections and political parties, especially electoral procedure and the law on political donations, as well as local government law, particularly the powers and duties of local authorities. Mathew acted for the appellant in Moss v KPMG LLP  EWHC 2923 (Admin), a statutory appeal against the refusal of an auditor to apply for a declaration that an item in a local authority’s accounts covering income received from penalty charge notices levied on motorists was unlawful.
Mathew was a member of the pro bono team of barristers who appeared for the claimant in R (Compton) v Wiltshire PCT  EWHC 1824 (Admin), in which the decisions of the Primary Care Trust in respect of facilities at Savernake Hospital in Marlborough were challenged. Cranston J's judgment set out the principles to be applied where it is alleged that the decisions of public authorities are vitiated by apparent bias on the part of their advisers.
A further area of Mathew’s public law practice is costs. Prior to the trial in the Savernake Hospital case, Mathew acted for the claimant in the High Court and in the Court of Appeal in R (Compton) v Wiltshire PCT  EWCA Civ 749,  1 WLR 1436, in which he obtained two protective costs orders which were both upheld on appeal. He has also successfully resisted applications for protective costs orders and advised on costs in several judicial review claims, including in one instance on an application for costs totalling more than £500,000.
Mathew has been published in Criminal Law Review (twice) on prison-related topics and also has published work relating to electoral law. Prior to joining 3PB he won numerous prizes for his work on public law including the Lee Essay Prize (Gray's Inn) for an essay on the impact of the Human Rights Act.
Asset and Tax Recovery
Mathew Gullick’s asset forfeiture work has seen him appear in the Supreme Court and in both divisions of the Court of Appeal, as well as the Crown Court. He also has experience of drafting and appearing in proceedings relating to restraint and enforcement receivership orders and in contempt of court proceedings arising from breaches of restraint orders.
In R v Ahmad and R v Fields  UKSC 36,  AC 299, Mathew appeared for the Home Secretary (led by First Treasury Counsel) in what is now the leading case on the approach to be applied in confiscation proceedings when offenders have benefited jointly from their crime, the Court in its judgment reviewing the case law and explaining the effect of the seminal judgment of Lord Bingham in R v May on this point as well as dealing with the approach to be applied in situations of potential “multiple recovery”.
In Minshall v (1) HM Revenue and Customs (2) Crown Prosecution Service  EWCA Civ 741,  Lloyd’s Rep FC 515, he appeared for the CPS in the Court of Appeal in a case involving a claim for restitution of the sum paid under a confiscation order arising from a decision of the European Court of Human Rights in 2011 that there had been unreasonable delay (and a breach of Article 6(1) ECHR) in the criminal appeal proceedings, which had finally concluded in February 2006. The Court held that the European Court’s decision provided no basis for such a claim and that the confiscation order was final and conclusive.
Mathew has also appeared in the Court of Appeal in R v Lambert & Walding  EWCA Crim 421,  2 Cr App R (S) 90 and R v Sivaraman  EWCA Crim 1736,  1 Cr App R (S) 80, on the principles to be applied to the calculation of an offender’s “benefit” under the Proceeds of Crime Act 2002, and in RCPO v Deprince  EWCA Civ 512, an innocent wife’s claim to a beneficial interest in the marital home which was subject to confiscation which also raised issues under the Human Rights Act.
Mathew’s civil practice enables him to bring expertise from other fields, including employment and contract law, into the sphere of asset forfeiture work. In addition, costs-only work is a significant element of Mathew’s general practice which he is keen to develop in the asset forfeiture context. He is particularly interested in the jurisprudence on the definition of “benefit” under the confiscation legislation following the House of Lords’ decision in the trio of cases led by R v May, and has lectured on this topic.
Mathew is a member of the Proceeds of Crime Lawyers Association (POCLA). He was appointed to the Attorney-General's A Panel of Junior Counsel to the Crown in civil matters in September 2016. He is a contributor to Millington and Sutherland Williams on the Proceeds of Crime (Fourth Edition, 2013 and Fifth Edition, 2018) (Oxford University Press).

Mathew Gullick advises on and appears in Employment Tribunal proceedings throughout the country, in cases ranging from those listed for one day to several weeks. He acts for both Claimants and Respondents (private, public and third sector) across the range of employment areas, including unfair dismissal, constructive dismissal, wrongful dismissal, all types of discrimination, TUPE, equal pay, restrictive covenants, public interest disclosure, pensions, breach of contract and unlawful deductions from wages (including the non-payment of bonuses).
Mathew is an experienced appellate advocate; his work in the employment field has included several appearances at substantive hearings in the Employment Appeal Tribunal, as well as in the Court of Appeal in the case of Sanders v Newham Sixth Form College  EWCA Civ 734, in which the Court clarified the correct approach to analysing claims of discrimination by failing to make reasonable adjustments for disabled persons, and most recently in The Harpur Trust v Brazel  EWCA Civ 1402,  IRLR 1012, the leading case on the approach to calculating the statutory paid holiday entitlement of workers on permanent contracts who only undertake work for part of the year (e.g. during academic terms).
Appeals in which he has appeared in the EAT include Franco v Bowling & Co Solicitors (UKEAT/0280/09), in which he successfully argued that an Employment Judge had no power at a case management hearing to impose a limit on the extent of a claimant's pleaded allegations of discrimination, and Premier Groundworks Ltd v Jozsa (UKEAT/0494/08) which concerned the definition of "worker" in the Working Time Regulations 1998, in particular the requirement to perform work personally under a contract for services.
Mathew’s employment practice also extends to advising on and appearing in High Court employment matters. He has been involved in several cases involving substantial six-figure damages claims, including for non-payment of bonuses and commission, wrongful dismissal and breach of a compromise agreement. He has also successfully struck out a libel claim brought by an employee against her former employer (a major PLC) in respect of correspondence sent at the time of her dismissal. Mathew also has experience of advising in relation to the provision of references by employers and consequent negligent mis-statement proceedings.
He was appointed to the Attorney-General's A Panel of Junior Counsel to the Crown in civil matters in September 2016.
Notable cases at first instance have included:
A direct age discrimination claim (acting for the successful Claimant) where the Tribunal found that the Respondent had made the Claimant redundant as part of a management restructure just before his 50th birthday in order to avoid paying a lump sum into the pension fund which would have been necessary in the event he had been made redundant after reaching the age of 50 (which would have enabled him to access his pension early). No consideration had been given to the case for delaying the Claimant’s redundancy for a transitional period to oversee work in progress, as had been done with other employees affected by the restructure; the Tribunal found that had this been done then the Claimant would have been made redundant after his 50th birthday and so would have received his retirement pension early. It rejected the Respondent’s alternative defence of justification and also found that the Claimant had been unfairly dismissed.
Acting (against Leading Counsel) for the successful claimant, a former Executive Director of an NHS Trust with 25 years’ unblemished service who had been summarily dismissed for gross misconduct for alleged misuse of the work email system. The dismissal took effect two weeks before the expiry of an existing redundancy notice period whereupon the Claimant would have received a substantial redundancy payment. The Tribunal found that the dismissal was both unfair and wrongful, concluding that no reasonable employer would have imposed anything more than a written warning and that the Respondent had failed to establish that the Claimant was guilty of gross misconduct. It further upheld the Claimant’s claim of disability discrimination arising from the Respondent’s failure to postpone the disciplinary hearing at which he was dismissed.
Acting for the Respondent at a Pre-Hearing Review in a claim concerning whether or not the provisions of the Civil Service Pension Scheme were discriminatory on the ground of disability – a deposit order was made and the claim subsequently struck out.
A three-day preliminary hearing (against Leading Counsel) on whether a carer funded by direct payments was an employee of the disabled persons cared for (but who did not have capacity to contract), their relatives who had day to day control of the employment relationship, the charity which administered the contracts, or the local authority with statutory responsibility for the provision of the care and which provided the funding.
Representing the defendant employer in Court proceedings brought by the employee to enforce payment under a purported compromise agreement which had been sent to the employee pre-signed but with the wrong figure for compensation inserted in error, which was three times higher than had previously been offered to the Claimant in writing. The Court found that the Defendant had orally withdrawn the offer to settle for the erroneous figure prior to the agreement being signed by the Claimant, and that in any event even if that withdrawal had not been effective then the agreement would have been void for mistake.
