Background
Plans to transform the former Horsham Golf Club site into an 800-home estate have long divided Southwater. Horsham District Council originally rejected the scheme citing *sustainability shortcomings* and inadequate active travel routes. However, after an appeal, the Secretary of State overruled the council, leaning on the National Planning Policy Framework to justify the project’s contribution to housing supply.
A flashpoint emerged when inspectors branded the recently adopted Southwater Neighbourhood Plan “out-of-date,” effectively sidelining local guidance. This move has become the heart of the council’s challenge.
Reasons for the Judicial Review
- Alleged legal errors: The council argues inspectors misapplied national policy tests for *sustainable development*.
- Neighbourhood plan status: Declaring the plan outdated, critics say, **undermines local democracy**.
- Sustainable transport: Insufficient weight, the council claims, was given to collaboration with Active Travel England on cycling and walking networks.
Legal Process
Judicial review focuses on the *legality*, not the merit, of decisions. A High Court judge will study written evidence, hear oral arguments, and decide whether the Secretary of State’s approval was lawful.
Key milestones include:
- Exchange of legal submissions.
- Pre-hearing protocol and potential mediation.
- Full hearing, likely late summer.
- Judgment and, if necessary, remedies such as quashing the permission.
Implications
If the challenge succeeds, neighbourhood plans nationwide may gain fresh legal muscle, compelling developers to meet higher sustainability bars. Conversely, a failed challenge could signal that local plans carry less weight when stacked against acute housing targets.
Stakeholder Reactions
“After careful examination, we believe the Planning Inspector failed to properly interpret national policy, particularly regarding sustainable development,” said Cllr Ruth Fletcher. “Public confidence demands judicial scrutiny.”
Southwater Parish Council backs the review, while many residents see the case as a litmus test for *community-led planning*.
Possible Outcomes
- Court upholds the challenge – permission quashed, project paused or redesigned.
- Court dismisses the challenge – development proceeds largely unchanged.
- Partial victory – scheme survives but gains stricter conditions (e.g., stronger cycling links, phased build-out).
FAQs
Why is the Southwater Neighbourhood Plan so important?
Neighbourhood plans allow communities to steer growth. If the court rules it was wrongly sidelined, similar plans across England could gain greater authority.
Does a judicial review stop construction automatically?
No. The approval remains in force unless the court issues an interim order or later quashes the decision.
How long will the review take?
Complex planning reviews typically run for several months, with a judgment expected before year-end.
Could this affect other Sussex developments?
Yes. A precedent on neighbourhood plan weight or sustainability standards could ripple through forthcoming appeals across the county.
