Securing planning permission from a Local Planning Authority (LPA) is a major milestone for any development project. However, when planning consent it is not always immediately immune to legal challenges.

Through a Judicial Review (JR), third parties such as local objectors, parish councils, or environmental action groups can challenge the lawfulness of the LPA's decision in the High Court (Planning Court). Understanding how the JR process works, the statutory timeframes involved, and how to de-risk your consent is essential for keeping your construction program on schedule.

1. What is a Judicial Review in Planning?

A Judicial Review is not an appeal against the planning criteria of a proposed scheme. The High Court does not assess whether a development is "good" or "bad." Instead, JR is a legal supervision system is adopted to determine whether the LPA followed the correct legal procedures and applied planning law properly when issuing consent.

To succeed, a claimant must present one of the primary legal grounds for JR:

• Illegality: The LPA not aligning with statutory planning policies (the National Planning Policy Framework), an overreach of statutory powers (ultra vires), or failing to take into account material planning considerations.

• Unfair Procedures: The LPA failing to follow compulsory statutory procedures, such as consulting with the public, inadequate Environmental Impact Assessment (EIA) screening, or a breach of natural justice.

• Irrationality: When the decision made by the LPA was so unreasonable that no sensible planning authority, acting logically, could have arrived at it.

2. Timelines and the Statutory 6-Week Window

Time limits in planning litigation are strictly enforced to provide commercially verify developers.

• The Statutory Deadline: Under Civil Procedure Rules (CPR Part 54), an application for judicial review of a planning decision should be filed promptly, no later than 6 weeks from the decision notice date.

• Pre-Action Protocol: Before issuing court proceedings, the claimant often sends a Letter Before Claim to the LPA (and the developer as an Interested Party) setting out the legal grounds.

• The Two-Stage Court Process:

  1. Permission Stage: A High Court judge reviews the papers to gage whether the claim is "arguable" and is realistic in succeeding.

  2. Substantive Hearing: If there is permission a full hearing takes place. The overall process from claim issuance to judgment can happen from 6-12 months.

Key Remedy: If the claim succeeds, the High Court issues a Quashing Order, making the planning permission have no legal effect and the application is sent back to the LPA to be re-determined lawfully.

3. How Developers Can De-Risk Planning Consents

While you cannot completely block a third party from filing a claim, developers can take proactive steps to prevent judicial review risks:

A. Ensure Impeccable Audit Trails During the Planning Stage

Work closely with your planning consultants and legal counsel during the application process to ensure the officer's report is legally viable. All environmental statements, consultee responses, and public representations should be explicitly addressed in the LPA's committee report.

B. Audit the Decision Notice and Committee Minutes

Once the LPA approves the application, conduct a thorough legal review of the committee report, decision notice, and draft planning conditions before the formal permission is issued. Solving potential risks or procedural gaps earlier reduces exposure to JR.

C. Delay Major Site Commitments During the 6-Week Challenge Window

Because the 6-week window is strictly enforced, avoid discharging pre-commencement conditions or committing investments to physical site works until the 6 weeks have happened without a claim being served.

D. Secure Judicial Review Insurance

If a threat of JR arises or if a site has a high public-profile risk, developers can consider specialist Judicial Review Indemnity Insurance. This policy covers legal defence costs, financial losses resulting from delays, or wasted build costs if there is ultimatetly no permission.

Judicial Review Risk Summary

Conclusion

A Judicial Review can stall a project and jeopardize financing, but understanding the legal triggers and strict 6-week timeline allows developers to manage exposure effectively. By working alongside the LPA to build a defensible planning record and holding off on capital deployment during the challenge window, you can successfully de-risk your development scheme.
