Background on the Planning Decision
The contested scheme grants outline permission for up to 800 homes plus community facilities on the former Horsham Golf Club site in Southwater. Initially refused by Horsham District Council, the application was later recommended for approval by the Planning Inspectorate. In July 2025, the Secretary of State endorsed the recommendation, overriding local objections.
“Every community deserves a meaningful voice in shaping its future,” a council spokesperson said, framing the legal battle as a defence of neighbourhood planning.
Reasons for the Judicial Review
- Legal Errors: The council argues that both the inspector and the Secretary of State misinterpreted key legislation.
- Conflict with National Policy: Approval allegedly ignored rules that favour development in sustainable locations.
- Neighbourhood Plan Undermined: The adopted Southwater Neighbourhood Plan was deemed “out of date,” challenging local democratic rights.
- Sustainable Transport: Limited active-travel links conflict with national guidance and advice from Active Travel England.
Legal Basis & Process
Judicial review allows the High Court to scrutinise whether a public body acted lawfully. Horsham’s claim, filed last month, centres on alleged misdirection in the inspector’s report and the Secretary of State’s final letter. Formal pleadings run to more than 60 pages, reflecting the complexity of planning law. The council has enlisted environmental barristers and is working closely with Active Travel England to fortify its transport arguments.
“This case could recalibrate the balance of power between Westminster and local planning authorities,” notes a planning law expert from the University of Sussex.
Implications
Should the council succeed, future appeals may place greater weight on neighbourhood plans and robust active-travel standards. Developers nationwide would likely face tighter scrutiny on walkability, cycling links and community-led visions. Conversely, an unsuccessful bid could embolden central intervention in local plans, accelerating housing delivery but potentially sidelining local voices.
Community Reactions
- Southwater Parish Council backs the review, calling it a “vital stand for community planning.”
- Some businesses welcome the development for jobs and spending power.
- Residents concerned about traffic and loss of green space applaud the council’s action.
- The Planning Inspectorate and the Department for Levelling Up, Housing & Communities have declined detailed comment during proceedings.
Potential Outcomes
The High Court could:
- Quash the approval, forcing a fresh decision or significant redesign.
- Order partial reconsideration, sharpening sustainable transport commitments.
- Dismiss the claim, allowing the 800-home project to advance unimpeded.
A preliminary hearing is anticipated this autumn, with a full hearing likely in early 2026.
Conclusion
The judicial review spearheaded by Horsham District Council represents more than a single planning dispute; it is a litmus test for the role of local voices in delivering much-needed housing. Whether the court sides with local autonomy or central decision-making, the judgment will echo through planning committees and council chambers across England.
FAQ
Why is Horsham District Council taking legal action?
The council believes the Secretary of State’s decision was legally flawed, undermined the Southwater Neighbourhood Plan and ignored sustainable transport policies.
Could the development still proceed if the council wins?
Yes. A successful challenge typically quashes the existing approval, but the developer could submit a revised application that addresses the court’s findings.
Does this case affect other neighbourhood plans?
Potentially. A ruling that reinforces neighbourhood plans would strengthen their status in future appeals nationwide.
What role does Active Travel England play?
Active Travel England has provided evidence on walking and cycling provisions, supporting the council’s claim that the scheme falls short of national standards.
When will the court make a decision?
Following the preliminary hearing, a full hearing is expected in early 2026, with judgment usually delivered a few weeks after.
