In addition, Gareth has particular expertise in claims concerned with the use of force by the Home Office and its contractors. He acted for Felix Wamala in a successful High Court assault claim against a Capita subsidiary in which, following a two week trial, an rare award of punitive damages was made given the seriousness of the misconduct exposed by the claim.

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.
Gareth has conducted housing, community care and social security cases throughout his career. Previously he was on the executive committee of Housing Law Practitioners’ Association (HLPA). Gareth now focuses on claims of particular complexity, which benefit from his substantial litigation experience and meticulous approach. This includes more serious unlawful eviction and claims concerns with serious building defects, in particular those which benefit from his experience in bringing personal injury claims. He also acts in test cases challenging decisions to cut or restructure housing-related services. He has for many years been ranked as one of the leading housing lawyers in the UK.
