Practice Summary

Hannah specialises in public law, planning and environmental law, local government law and human rights. Her broad experience in public law makes her a strong choice for any judicial review or statutory challenge.

Hannah has acted as sole or junior counsel in litigation in the High Court, Court of Appeal, Supreme Court, County Court and various tribunals, including the First-tier Tribunal (Special Educational Needs and Disability).

She regularly acts for clients in planning appeal hearings and inquiries, some of which have concerned major residential, regeneration and infrastructure projects. Her recent inquiries (as junior counsel) include the Howbury Park Strategic Rail Freight Interchange, the Whitechapel Estate, and the Sainsbury’s Foodstore in Whitechapel.

Hannah’s public law practice has a particular emphasis on medical law and law of the NHS. She is currently instructed as junior counsel to David Lock KC to represent a large group of core participants in the upcoming Infected Blood Inquiry into the contaminated blood scandal of the 1970s and 80s.

She is the author and editor, along with David Lock KC, of NHS Law and Practice, published by Legal Action Group. It is the first comprehensive guide to the structures and frameworks of the NHS and has been described by Sir James Munby as “truly a ground-breaking book” which “no one who needs to understand NHS law could afford to be without”.

NHS Law and Practice explains the legal relationships between NHS commissioners and primary care, community and acute providers of NHS services, as well as explaining the structure of NHS regulation. It provides a detailed guide to enforcing patients’ legal rights around NHS continuing healthcare, patient choice and personal budgets.

Hannah also teaches medical law to undergraduates at the London School of Economics, dealing with various legal and ethical matters such as medical malpractice, health resource allocation, mental capacity, mental health, informed consent, organ donation, abortion, assisted dying, fertility treatment and genome editing.


Hannah practises in all areas of planning and environmental law. She advises and acts for developers, individuals, local authorities, local residents’ groups, NGOs and other interested parties. She has substantial experience in High Court proceedings, informal appeal hearings, inquiries and magistrates’ court enforcement proceedings. Her broad public law and local government practice gives her a strong foundation in all aspects of judicial review. As such, Hannah is well placed to deal with planning judicial reviews and statutory challenges (including section 288 challenges) as sole counsel or led.

She also is able to advise clients about their public law and statutory duties in matters such as: conduct of meetings, conflicts of interest, the public sector equality duty and equality impact assessments, advertisement and notification requirements, and consultation.

Landmark's barristers often work at the intersection of our core practice areas; bringing a wide range of skills, knowledge and experience to bear on a particular dispute or issue facing a client.

Our focus is always on achieving the best possible outcome for our client. By viewing the client's objectives in a holistic way - and not purely through the lens of one rigidly-defined legal area - we deliver the best possible advice and representation in complex matters that engage multiple specialist areas of law. 

Whether it's providing support as an individual cross-practice barrister or a cross-disciplinary team of Landmark counsel, we are able to draw on an outstanding array of complementary skillsets and knowledge bases. This often achieves a better result than instructing multiple barristers from different specialist sets. This also improves the quality of client care through increased levels of communication, quicker response times, and a coordinated approach to clerking and fees, made possible by our team-based cross-practice approach.

Please contact our practice management team for more information.
