Public and Regulatory

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:

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 [2019] UKSC 2, [2019] 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 Andukwa) v Secretary of State for Justice [2014] EWHC 3988 (Admin), [2015] ACD 54 - where a conviction was reversed on the ground that there had been an available statutory defence which had been overlooked at trial, there was no ‘new or newly discovered fact’ and so compensation was not payable.

R (on the application of Hussain) v Secretary of State for Justice [2013] EWHC 1452 (Admin), [2013] 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.

In Secretary of State for Work and Pensions v Cattrell [2011] 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 [2010] 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 [2009] 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 [2008] EWCA Civ 749, [2009] 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 [2014] UKSC 36, [2015] 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 [2015] EWCA Civ 741, [2015] 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 [2012] EWCA Crim 421, [2012] 2 Cr App R (S) 90 and R v Sivaraman [2008] EWCA Crim 1736, [2009] 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 [2007] 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).
