High Court dismisses first challenge by Windrush victims to compensation scheme - May 2023
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 been a member of the Attorney-General’s panel of Counsel since 2006 and was appointed to the A- Panel in 2015 (re-appointed in 2019). 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.
His significant human rights cases include challenges under Articles 3, 5 and 8 to the accommodation of asylum seekers in Napier Barracks (R(NB) v SSHD), the Detention Action case in respect of the use of immigration detention during the Covid-19 lockdown, R(Osborn) v Parole Board in the Supreme Court on the requirements of procedural fairness under Article 5, and R(LW) v Sodexo and SSJ, which is the leading authority on the residual responsibilities of the SSJ for breaches of Articles 3 and 8 by a private prison operator.
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.
