Daniel is recommended by Chambers UK Guide to the Legal Profession as a leading solicitor in civil liberties, police law, prison law and public and administrative law. He "is a giant in the field," of civil liberties, according to the 2013 edition of Chambers, which also says that he is "an expert in public and administrative law and an expert in fighting cases against police forces: with his knowledge and experience he is one of the best around", and an “extremely bright, sharp and experienced lawyer" who is "very astute, very intelligent and very passionate."
Previous editions of Chambers describe him as "a hugely impressive figure and a talented lawyer"; “extremely intelligent and relentless on behalf of his clients” as well as being “cerebral, assured and experienced in high-level cases” with “a first-class ability to think creatively and assimilate the facts of a case swiftly and thoroughly, with a tactical approach”; and a "...fantastically sensible and committed lawyer who is not afraid to get stuck in and take on large challenges."
Daniel qualified as a solicitor in 1988. He joined Hickman & Rose in 1997 as head of the Civil Litigation department and became a partner in 1998.
He specialises in international human rights law, civil actions against the Ministry of Justice, Home Office and police and in representing bereaved families at inquests into deaths in custody. He brought the group action for prisoners alleging assault and systemic management failures in HMP Wormwood Scrubs which lead to compensation payments totalling over £1million and a report by the Chief Inspector of Prisons recommending closure or privatisation of the prison.
His test cases include the right of prisoners to vote, the frequency of review of lifers’ release dates and the application of the Human Rights Act to officials acting outside the United Kingdom. In recognition of his work, Daniel received the Margery Fry Award from the Howard League for Penal Reform for ‘ensuring the protection of prisoners through the tenacious pursuit of legal remedies’.
Daniel’s work for victims of war crimes, torture and crimes against humanity has placed him at the forefront of the movement for universal criminal jurisdiction over the most serious human rights violations and the equal application of the rule of law in all circumstances. In light of his expertise, he has been invited to address members of the International Bar Association and members of the European and UK Parliaments in London and Brussels on the theme of universal jurisdiction.
He has been interviewed and published articles in the mainstream press and legal journals. Daniel is currently Chair of INQUEST, the charity which provides a specialist, comprehensive advice service to bereaved people and others on contentious deaths and their investigation.
