David Manknell

Public Law

David has acted in hundreds of claims for judicial review across a broad range of areas including healthcare, prison law, regulatory proceedings, education, licensing, asylum, immigration and national security matters, and often on further appeal to the Court of Appeal. He has particular expertise in cases involving direct challenges to policy changes, including issues about consultation. Many of his cases concern issues of equality and discrimination law.

He has been a member of the Attorney-General’s panel of Counsel since 2006 and was appointed to the A-Panel in 2015. He is regularly instructed in cases that are high profile, and often featured in the national press, and those which relate to very sensitive issues for his clients.

Examples of recent cases include the litigation in respect of the child refugees dispersed from the camp in Calais, Osborn in the Supreme Court on the requirements for Parole Board hearings, Sturnham in the Court of Appeal on damages for Article 5 breaches, the series of joined cases concerning reception conditions in Cyprus for asylum seekers, challenges to local authority taxi licensing policy, and challenges to the prison “book ban”. He has both challenged and defended NHS healthcare decisions in respect of hospital closures, refusal to provide treatment, and health authority reorganisations. In 2015 he was junior counsel to the IPT in the claims about GCHQ surveillance arising from the Edward Snowden leaks.

He has a thorough knowledge of all aspects of procedure for judicial review, including where urgent and immediate relief is needed from the Court.
