I specialise in public law, including administrative law, constitutional law and human rights. I also have experience in comparative public law and aspects of civil procedure, and am a regular peer reviewer for papers in these areas.
My recent work includes multiple contributions on the legal and human rights aspects of COVID-19 regulations, including peer-reviewed papers in interdisciplinary, public health and science journals. My analysis and recommendations submitted to the UK House of Lords Constitution Committee were adopted in its Report on COVID-19 and the Use and Scrutiny of Emergency Powers. I am also the Rapporteur for the Hong Kong SAR on The Oxford Compendium of National Legal Responses to COVID-19 project run by University College London, King's College London and the Max Planck Institute of Comparative Public Law and International Law. I am, along with Denis Edwards, the co-editor of a new Administrative Law Reissue in The Laws of Scotland: The Stair Memorial Encyclopaedia, the most authoritative statement of Scots law, and co-editor of a forthcoming second edition of Judicial Review by The Rt. Hon. The Lord Clyde and Denis Edwards. I am the author of the leading text on administrative law in Hong Kong, published in 2018 by Cambridge University Press. In addition, I am the author of the only text to have been written on the nobile officium (the extraordinary equitable jurisdiction), cited with approval in the supreme courts of Scotland.
I am a Legal Adviser to the Ombudsman of Hong Kong by statutory appointment, a member of the Constitutional Affairs and Human Rights Committee of the Law Society of Hong Kong, and an examiner in constitutional law on the Law Society of Hong Kong's Overseas Lawyers Qualification Examination. I held a visiting appointment as a Herbert Smith Freehills Visitor at the University of Cambridge, and have presented my work at a range of institutions around the world including Harvard Law School, the University of Cambridge, the University of Melbourne, the National University of Singapore and Peking University.
