Background of the Planning Decision
The controversial proposal involves redeveloping the former Horsham Golf Club site into a modern community of up to 800 homes, complete with green spaces and local facilities. Initial refusal by Horsham District Council stemmed from concerns over location suitability and limited travel options. In July 2025, the Planning Inspectorate recommended approval, and the Secretary of State formally granted outline permission, overruling local objections.
- Application approved in July 2025 after an appeal.
- Site spans the picturesque edges of Southwater village.
- Community facilities and public green corridors promised by the developer.
Reasons for the Judicial Review
Horsham District Council argues the approval clashes with national and local planning frameworks:
- Misinterpretation of National Planning Policy: alleged failure to apply sustainable development tests.
- Undermining Local Autonomy: the Southwater Neighbourhood Plan 2021 was deemed “out-of-date” despite its recent adoption.
- Sustainability Concerns: limited provision for public transport, cycling, and walking routes.
“It is vital for public confidence in the planning system that such matters are scrutinised by the Courts,” insisted Cllr Ruth Fletcher, Cabinet Member for Planning & Infrastructure.
Legal Basis & Process
The judicial review, lodged in the High Court, focuses solely on the legality of the decision—not the merits of the housing scheme. Grounds include:
- Misapplication of national planning policy.
- Inadequate consideration of neighbourhood-plan status.
- Potential procedural unfairness in the appeal process.
Implications for the Local Community
Residents are divided. Opponents fear infrastructure strain, traffic congestion, and erosion of village character, while supporters emphasise the pressing need for new homes and economic vitality.
- Traffic hotspots on Worthing Road could see peak-hour flows double.
- Local GP surgeries may need to serve an extra 2,000+ patients.
- Proposed green corridors could add 10 ha of public open space.
Stakeholder Perspectives
Horsham District Council: determined to defend neighbourhood planning rights.
Developers: argue the decision delivers much-needed housing.
Residents’ Groups: a mix of guarded optimism and deep scepticism.
Role of Active Travel England
Active Travel England is formally supporting the judicial review, contending that cycling lanes and pedestrian links were “bolt-on afterthoughts” rather than integrated design features. A spokesperson remarked, “New developments must embed active travel from day one if we are serious about decarbonising transport.”
Next Steps & Potential Outcomes
Court hearings are expected later this year. Possible rulings include:
- Decision upheld: development proceeds largely unchanged.
- Decision quashed: a fresh determination required, adding months—or years—of delay.
- Partial quashing: specific conditions revisited, such as transport or environmental mitigation.
Whatever the verdict, it will set a precedent for how future large-scale housing schemes interact with neighbourhood plans across West Sussex and beyond.
FAQs
Why is Horsham District Council challenging the decision?
The council believes national planning policy was misapplied and that the Southwater Neighbourhood Plan was unfairly dismissed.
Does the judicial review stop construction work?
Yes. Until the High Court rules, the developer cannot proceed beyond preliminary site investigations.
What happens if the decision is quashed?
The Secretary of State would need to re-determine the application, taking the Court’s findings into account.
How can residents stay informed?
Updates will appear on the Horsham District Council planning news page and local press outlets.
