Judicial review & public law

Gareth has many years’ experience in conducting judicial reviews and other public law challenges for individuals and organisations. He has a track record of success at all levels to and including the Supreme Court. This has included successful challenges in areas as diverse as public sector procurement, community care, further education, environmental law, social security, housing, planning, criminal justice, immigration, social security, pensions, and cuts of services by both central and local government. For several years Gareth was the author of the Solicitors’ Journal judicial review updates.

Detention & deprivation of liberty

Gareth is an expert in false imprisonment and/or deprivation of liberty claims, including related claims for assault. Much of his work has been in the context of immigration detention, securing orders for release and damages for unlawful Home Office detention. In addition, Gareth has particular expertise in claims concerned with the use of force by the Home Office and its contactors. Separate to this, Gareth acts for children and vulnerable adults who have been unlawfully deprived of their liberty, for example in hospitals or residential care settings. In doing so, Gareth is able to draw on his substantial mental health and community care expertise.

Failures to protect

Gareth is experienced in conducting claims for damages for failures to protect children and vulnerable adults from abuse and neglect. Gareth is able not only to provide representation in claims for compensation – securing funds that go some way to enabling his clients to move forward positively with their lives – but also to ensure that their community, housing and other essential support needs are met on an on-going basis through the use of judicial review proceedings. Whilst most of Gareth’s work is for children and vulnerable adults in the community, he has also brought successful claims for failures to protect in custodial settings.

Discrimination & equality

Gareth is an expert in discrimination and equality law. He has successfully conducted a wide range of claims securing compensation and injunctions to remedy breaches of the Equality Act, both against private companies and local and central government. For example, he represented a Community Interest Company in a successful equality duty challenge to a decision to terminate a £2 million grant, he has used the Equality Act to secure the discontinuance of a prosecution by the CPS, and he has brought numerous successful reasonable adjustments claims for disabled people.

Gareth also has significant expertise in discrimination claims based on article 14 of the European Convention on Human Rights and on EU law. He acted for Denise Brewster in her ground-breaking appeal to the Supreme Court where for the first time the Court upheld a complaint of unlawful discrimination on grounds of marital status. He has also used article 14 to challenge successfully the way reparations to Holocaust survivors are treated under for social security purposes.

Housing, destitution & social services

Gareth has conducted housing, community care and social security cases throughout his career and was previously on the executive committee of Housing Law Practitioners Association. Gareth focuses on claims of particular complexity, which benefit from his substantial litigation experience. This includes more serious unlawful eviction and disrepair claims which benefit from his experience in bringing personal injury claims, as well as test cases challenging decisions to cut or restructure housing-related services.

Information and privacy rights

Gareth has experience of bringing successful defamation claims and claims for breaches of the Data Protection Act. In particular, Gareth is experienced in claims concerned with the retention and dissemination of false information by public bodies. He is also experienced in securing orders for the deletion or rectification of such information, as well as compensation for the damage that has been caused.
