Leon specialises in public and planning law. He often acts in complex and high profile litigation, and has acted in cases up to the Supreme Court and the European Court of Human Rights.

In public law, his cases have included the challenge to Ofqual’s grading system for the 2020 A-level exams, the Alfie Evans litigation, the challenge to the NHS Accountable Care Organisation contract, the challenge to the Yorkshire Ripper’s move from Broadmoor to prison, and the challenge to the UNITE leadership election. In planning law, he regularly appears in the High Court (having six reported judgments in 2019) and regularly appears at inquiries. A full list of his cases is available under the ‘Reported Cases’ tab.

Across Chambers and Partners and the Legal 500, Leon is ranked as a leading junior in four categories: Administrative Law and Public Law, Education Law, Planning Law and Social Housing Law. He is described as “incredibly bright and able to get to grips with cases quickly” (Legal 500 2020) and a “rising star” who is “clear, concise and cuts through excess details” (Chambers and Partners 2020).

He has been appointed to the Attorney General’s B Panel of Counsel, and regularly acts for the Secretary of State in both public and planning cases; and is also on the Equality and Human Rights Commission Panel of Counsel.

Leon is a tutor in Administrative Law at the Faculty of Law, University of Cambridge. He is also a contributing author to both ‘Children’s Social Care Law’ (LAG, 2018) and ‘Adult Social Care Law’ (LAG, 2019). He is co-author of a comprehensive free guide to the law relating to special educational needs, the ‘Noddy Guide to SEN’.

Away from law, he is a Governor of Dr Challoner’s Grammar School (SEN and Diversity Governor and Chair of the Admissions Committee).
