William Upton QC is a barrister specialising in planning, environmental and local government law. As a result, his experience ranges across the civil and criminal courts, as well as planning inquiries. He has acted for local authorities, the Environment Agency, private developers and third parties.

A major part of 2014-2015 was spent on Lawrence v Fen Tigers Ltd and others  UKSC 13 (noise nuisance from motorsports), in which the Supreme Court significantly reviewed the law on private nuisance, including its relationship with the planning regime. The second hearing was held in May 2014,  UKSC 46, on the issues of the landlord’s responsibility for the nuisance and the potential unfairness of the costs (CFA and ATE insurance). The third hearing was heard in February 2015  UKSC 50, on the potential incompatibility of the costs regime with human rights, and there were 8 intervening parties including the Secretary of State for Justice, the Bar Council, and the Law Society. William was involved at the Court of Appeal and the High Court stages, and was the original counsel in the case.
Other recent court cases have included Cooper Estates v Tunbridge Wells BC  (reasons in Local Plan reports), R (Birchall Gardens LLP & Tarmac) v Herts County Council  EWHC 2795 (Admin) (planning, natural justice and costs), Thomas v Merthyr Tydfil Motor Car Auction  Env. L.R. 4 (noise nuisance), R (on the app of Perry) v London Borough of Hackney and another (planning and issues over the confidential viability assessment),  EWHC 3499 and  EWCA Civ 1372 (disclosure).
His planning work has included the skyscraper developments at Lambeth Bondway and Vauxhall Cross planning inquiries, as well as advising and arguing about housing land supply and viability issues at planning inquiries.
He continues to advise local authorities on their development plan work, following his work on the adoption of the first DPD in England back in 2007 (for Maidstone Borough Council). His work has included the Examinations into the Swale Local Plan (2016 and 2017), West Berkshire Site Allocations DPD (2016), West Berkshire Council Core Strategy (2012), the Greater Norwich Area Joint Core Strategy (2010/2011) and Tunbridge Wells Borough Council Core Strategy (2010). He acted for the London Borough of Tower Hamlets on its Community Infrastructure Levy examinations (2014), including issues relating to Crossrail funding and new development at Canary Wharf, and for the CIL examination by the London Borough of Hackney.
Recent advice on Environmental Permits has included dealing with revocation appeals, and the judicial review challenge to the removal of the waste management exemption that failed to comply with the Waste Framework Directive Objectives. He has also advised extensively on flood rights, highways, rights of way, commons and navigation law issues. He appeared for the Environment Agency in the Hampstead Heath Ponds case, R (on the application of the Heath & Hampstead Society v Mayor and City of London and the Environment Agency  EWHC 3868 (Admin), particularly to deal with the issues of safety and the Reservoirs Act (as recently amended). Rights of way cases have included Wild v Secretary of State for Environment Food and Rural Affairs  2 E.G. 85, CA, and Elveden Farms v Secretary of State for Environment Food and Rural Affairs  All ER (D) 183 (Jan). These areas also raise many enforcement and regulatory issues, and William has also found himself defending food safety issues at Smithfield market.
