Practice Summary

Gwion is a leading barrister in the areas of planning, environmental and public law and took silk after only 16 years in practice. Described by clients as a “force of nature”, he has an established reputation as a litigator, with solicitors consistently commending him for his “brilliant” advocacy, “fearsome” cross-examination and being “a pleasure to work with” (Chambers & Partners).

Gwion regularly appears in high-profile litigation in his areas of expertise. He is most widely known for acting for the successful party in the Hillside Parks litigation about multiple planning permissions for the same land, arguably the most significant planning case to reach the Supreme Court in the last 20 years.

Gwion’s practice also received national attention when a former Secretary of State conceded in the High Court that he had acted with apparent bias when granting planning permission for the Westferry Printworks redevelopment in east London. Gwion acted for the successful party, Tower Hamlets Council.

Gwion’s clients are diverse. He purposely retains a broad client base in both the private and public sectors so that his clients benefit from his understanding of how different parties are likely to approach a problem.

Planning inquiries are a major part of his practice. Gwion has extensive experience of acting for developers in appeals raising difficult issues in relation to design, architectural quality, cultural heritage and viability, especially in and around London. For further details of these cases, please click on the ‘Planning’ tab above.

Highly technical planning and environmental appeals where experts disagree about environmental impacts also feature heavily in Gwion’s practice given his “forensic” approach to evidence and “ability to rapidly absorb, filter and distil” technical material (Chambers & Partners).

Gwion regularly acts for leading national housebuilders across England and Wales, including Persimmon, William Davis and Bloor, and has achieved many successful outcomes for boutique residential developers in both urban and rural locations.

Since taking silk, Gwion has acquired further expertise in promoting market-leading retirement schemes at appeal. Current clients include KYN (a dementia care home and research centre in Cambridge) and Elysian Residences.

He also works frequently with clients from the retail sector. Recent successes include a series of judicial reviews for the Midcounties Co-operative to overturn planning permissions granted to a competitor, and defeating a rival developer’s proposal to demolish the Homebase store in Saffron Walden.

In addition to acting in planning appeals, Gwion has considerable experience of the development consent process for large infrastructure projects, having acted for Natural Resources Wales, the Welsh environmental body, in all the high-profile Welsh DCO hearings of the last 10 years (including the proposal for a new nuclear power station on the Wylfa site on Anglesey; the Awel y Môr offshore windfarm near to the north Wales coast; and the proposal for the world’s first man-made, energy-generating tidal lagoon at Swansea Bay).

Gwion enjoys long-standing relationships with many public bodies in England and Wales, building on his previous experience as a member of both the Attorney-General’s ‘A’ Panel of Counsel, and the Welsh Government’s Panel of Junior Counsel, before taking silk. He is regularly instructed by the Environment Agency in judicial reviews and environmental permitting appeals and is currently leading the Agency’s climate change officials in defending the first tranche of civil penalties imposed on aircraft operators under the UK’s new Greenhouse Gas Emissions Trading Scheme.

Gwion’s regular local authority clients include (to name only a few) Hounslow Council, Tower Hamlets Council, Chichester District Council, Torbay Council, Mid Sussex District Council, South Hams District Council and the South Downs National Park. In the recent directories, a local authority client praised Gwion for his consistently “punchy” and “succinct” written advice that makes “complicated cases look straightforward despite difficult points” (Chambers & Partners). His work for local authorities spans the full range of their functions, including education, elections and ethical standards.

Gwion is based in London but welcomes instructions from all parts of the United Kingdom and from international clients. He is Welsh-English bilingual.

Planning

Gwion advises on all aspects of planning law and he appears regularly in inquiries, in hearings and in court in this area. The main legal directories have recommended Gwion as a leading barrister in planning law for several years: “A go-to barrister for planning disputes”; “A formidable advocate”; “An intellectual star”; “Ferocious in court and on paper” (Chambers and Partners); “Very smart and excellent on his feet”; “Very user-friendly and easy to work with” (Legal 500). Gwion has acted for clients in many of the leading planning cases of the last 20 years, including the long-running Hillside Parks litigation that reached the Supreme Court in 2022, where he acted for the successful party.

Gwion has substantial experience of acting for leading housebuilders (Persimmon; William Davis; Bloor; Jelson; Barwood); the retail sector (Homebase; Co-operative Group; Tesco; Toni & Guy); the residential care sector (KYN; Elysian Residences); the entertainment sector (Andrew Lloyd Webber’s Really Useful Group; Pinewood Studios) and the hospitality sector (Mayfair’s Dorchester Hotel). He also has considerable experience of infrastructure schemes, advising developers, local authorities and regulators on energy schemes and port-related development across England and Wales.

For the last 15 years, Gwion has acted for Natural Resources Wales (and its predecessor bodies) in almost all its environmental litigation in the higher courts. He is also frequently instructed by the Environment Agency, Defra, the Welsh Ministers and the Marine Management Organisation in appeals and judicial review claims that raise issues of environmental law.

Public and Administrative

Public law is at the heart of Gwion’s practice. For several years, the main legal directories have identified Gwion as a leading public law barrister, with clients commending him for being a “top-class advocate” (Legal 500) who delivers “extremely effective” pleadings and “very succinct and focused” advice (Chambers & Partners).

Before taking silk, Gwion was a member of both the Attorney General’s ‘A’ Panel of Junior Counsel and the Welsh Government’s Panel of Junior Counsel. This meant that he regularly acted for the UK and Welsh Governments in their most complex cases. Since taking silk, Gwion has continued to represent both Governments regularly in the higher courts and in international litigation.  

Many of Gwion’s cases feature aspects of planning and environmental law, but his interest in public law and judicial review extends more broadly to issues arising in immigration, human trafficking, education, equality and discrimination law, detention, electoral law, transport, standards and ethics, care standards and property-related public law.

In recent years, Gwion has acted for the UK Government in most of its litigation in the higher courts raising issues under the Council of Europe Convention on Action Against Trafficking in Human Beings and Article 4 ECHR. He has also represented the UK Government in almost all of its significant cases on the Dublin III Regulation since 2016.

Gwion has particular interest in public law issues arising from the devolution settlement for Wales. His regular clients in Wales include the Welsh Ministers, Natural Resources Wales, the Welsh Language Commissioner and the Public Services Ombudsman for Wales. In 2014, Gwion became the first Counsel in history to undertake a High Court trial entirely through the medium of Welsh.

Gwion also has established relationships with several local authorities and National Park authorities across England and Wales. Gwion advises on all aspects of local government work, with a particular expertise in education, elections and ethical standards.

Cross-practice

Landmark's barristers often work at the intersection of our core practice areas; bringing a wide range of skills, knowledge and experience to bear on a particular dispute or issue facing a client.

Our focus is always on achieving the best possible outcome for our client. By viewing the client's objectives in a holistic way - and not purely through the lens of one rigidly-defined legal area - we deliver the best possible advice and representation in complex matters that engage multiple specialist areas of law. 

Whether it's providing support as an individual cross-practice barrister or a cross-disciplinary team of Landmark counsel, we are able to draw on an outstanding array of complementary skillsets and knowledge bases. This often achieves a better result than instructing multiple barristers from different specialist sets. This also improves the quality of client care through increased levels of communication, quicker response times, and a coordinated approach to clerking and fees, made possible by our team-based cross-practice approach.
