Background of the Planning Decision
In July 2025 the Secretary of State approved a proposal for an 800-home development on the former Horsham Golf Club site in Southwater. The scale of the project promised a major boost to local housing supply, yet immediately raised eyebrows over its fit with established neighbourhood and district plans.
Reasons for the Judicial Review
Horsham District Council argues the approval contains several legal and policy missteps:
- Conflict with the Southwater Neighbourhood Plan — adopted in 2021, the plan caps large-scale developments in the area.
- Unclear alignment with national planning policy and sustainable development goals.
- Perceived erosion of local decision-making power, undermining community-led planning.
Legal Process and Involvement
The judicial review, overseen by the Planning Inspectorate, will determine whether the Secretary of State’s decision complied with planning law. Agencies such as Active Travel England have been consulted, reflecting the heightened focus on walkability and cycling infrastructure.
Implications for Local Planning
A ruling in favour of the council could:
- Reinforce the authority of neighbourhood plans when assessing large schemes.
- Compel developers to integrate stronger sustainable transport measures.
- Set a precedent for other councils seeking to defend local policies.
Impact on Sustainable Development & Transport
Critics say the development’s current transport plan lacks sufficient cycling lanes and bus connectivity. The council insists that long-term environmental health demands robust active travel options rather than a car-centred layout.
Current Status & Next Steps
The High Court has granted permission for the case to proceed, though a hearing date is yet to be set. A council spokesperson stated, “This judicial review is about safeguarding our community’s vision for sustainable growth.” Meanwhile, residents follow updates closely via outlets such as the Local Government Lawyer article.
Conclusion
The Horsham judicial review highlights the delicate balance between local autonomy and national housing ambitions. Whether the court sides with the council or upholds the Secretary of State’s approval, the decision will resonate far beyond Southwater, influencing how future developments incorporate sustainability, transport, and community wishes.
FAQ
Why did Horsham District Council launch a judicial review?
The council believes the 800-home approval clashes with the Southwater Neighbourhood Plan and may breach national planning policy, potentially undermining local planning authority.
What is a judicial review in the context of planning?
A judicial review allows a court to examine whether a public body, such as the Secretary of State, made a decision lawfully and followed correct procedures.
Could the development still proceed if the council wins?
Yes. A successful review would likely quash the permission, but the developer could submit a revised application addressing the court’s findings.
How might the case impact sustainable transport planning?
If the court emphasises active travel requirements, future housing schemes across the UK may need to prioritise cycling, walking, and public transport infrastructure.
