Tim practices in information law, public law, local government law, and employment law.

Information law is a fast-moving area of the law, where legal principles often struggle to catch up with technological and social change.  Personal information is both a valuable asset and a essential tool when delivering public services; but its effective exploitation is a legal minefield.  Tim has extensive experience in this field in which he is widely recognised to be a leading expert.  Tim’s knowledge and experience mean that he is ideally placed to advise organisations of all kinds, both in the private and public sector, about novel and complex problems relating to their use of information.

Tim combines his work in information law with a wider practice in public and employment law, having practised in both of these areas throughout his time at the Bar.



Tim has practised in employment law throughout his career, and is equally at home arguing a short point of law in the Court of Appeal or conducting a fact-heavy Tribunal case about discrimination or whistleblowing. He has a particular interest in the law about employment vetting and monitoring, and was involved in the leading Supreme Court case about CRB disclosure.

Recent work includes:

  • Acting for a University in a discrimination claim brought by a current employee
  • Advising and acting for a public authority in a multi-party case under the Transfer of Undertakings Regulations
  • Dealing with litigation arising out of the maintenance of an alleged industry blacklist


Tim’s information law practice covers areas such as data protection, freedom of information, access to environmental information, RIPA, human rights issues, privacy, and breach of confidence. His clients include commercial organisations, the Information Commissioner, numerous regulators, NHS bodies, local authorities, Universities, and private individuals. His freedom of information cases have considered the disclosure of Cabinet Minutes about the Iraq War, MPs’ expenses, abortion statistics, and the risk register relating to the Government’s NHS reforms. He has extensive advocacy experience in information law, at all levels from the First-tier Tribunal to the Supreme Court.He has advised a wide range of commercial organisations (e.g in the banking, insurance, healthcare and outsourcing sectors) about their use of customer and other personal information, and about the implications of sharing confidential business information with public authorities.


In recent years Tim’s wider public law and local government practice has covered issues about public sector pensions, the powers and duties of regulatory bodies, and local authority vires.  He has acted for an against regulatory bodies in judicial review claims arising out of the exercise of their statutory powers.
