Judicial Review in the Planning System
The planning system is an intricate balance between the needs of development, environmental protection, and public interest. When an individual, business, or community group disagrees with a decision made by a local planning authority or the planning inspectorate, they may consider avenues such as a planning appeal or judicial review. While planning appeals focus on the merits of a planning decision, judicial review is a legal process that determines whether the correct procedures were followed when making that decision. Understanding how judicial review fits within the planning system is essential for anyone engaging with planning law, as it provides a vital check on the exercise of administrative power.
Understanding the Planning System and Planning Appeal
The planning system in the UK is designed to regulate the development and use of land in the public interest. Local planning authorities (LPAs) are responsible for making decisions on planning applications in their area, guided by local and national planning policies. When an application is refused, granted with conditions the applicant finds unacceptable, or isn’t determined within the statutory timeframe, an applicant has the right to lodge a planning appeal.
A planning appeal is typically made to the Planning Inspectorate (in England and Wales), which reviews the decision afresh, considering both the original application and any further evidence. Appeals can relate to a refusal of permission, imposition of conditions, or non-determination. However, there are instances where a planning appeal may not be available, particularly for decisions taken outside the scope of formal applications or where no right of appeal is provided in law.
The Nature of Judicial Review in Planning
Judicial review is not a re-examination of the merits of a planning decision; rather, it is concerned with the lawfulness of the process by which a decision has been made. It is a remedy of last resort in the planning system and is only available once all alternative remedies, such as a planning appeal, have been exhausted or are not available.
In the context of planning, judicial review can be sought by individuals or groups who are directly affected by a planning decision – such as a neighbouring landowner or a community group – if they believe that the decision-maker acted unlawfully. This could mean the decision was made outside the powers conferred by law (ultra vires), the correct procedures were not followed, or that the decision was irrational or unreasonable by legal standards.
Grounds for Judicial Review in the Planning System
The main grounds for seeking a judicial review in planning include:
- Illegality: The public body acted beyond its powers, misunderstood legal requirements, or applied policies incorrectly.
- Irrationality: The decision is so unreasonable that no reasonable authority would make it.
- Procedural Impropriety: There was a failure to follow due process, such as a lack of proper consultation, bias, or a breach of the rules of natural justice.
- Breach of Human Rights or Environmental Obligations: If a decision impinges upon recognised protected rights or fails to comply with statutory environmental assessments.
Crucially, a judicial review does not determine whether a planning decision was ‘right’ in substance but whether it was reached properly, taking into account all legally relevant considerations and proper procedures.
How Judicial Review Differs from Planning Appeal
It’s crucial to distinguish between a planning appeal and judicial review. A planning appeal examines the planning merits and can substitute a new decision for that of the local authority. For example, if a development is refused by a local authority, the Inspectorate can overturn the refusal on appeal after considering all of the evidence.
By contrast, judicial review does not override the planning decision or substitute the judge’s evaluation for that of the planning authority. Instead, if the court finds the decision to be unlawful, it quashes the decision and requires the authority to reconsider, this time in accordance with proper legal procedure. In most cases, a planning appeal is the preferred remedy where available, since courts are slow to intervene in policy decisions best left to planning authorities.
The Process of Judicial Review in Planning
Judicial review in the planning system follows a strict and prompt timetable. If you wish to challenge a planning decision, you must generally do so within six weeks of the decision being issued. The process steps typically include:
- Pre-action Protocol: An applicant notifies the decision-maker and other relevant parties of their intention to seek judicial review, giving them a chance to reconsider or resolve the issue before court proceedings begin.
- Permission Stage: The claimant applies to the High Court for permission to proceed. The court will consider whether there is an arguable case.
- Hearing: If permission is granted, a hearing is held where both parties present their arguments. Third parties can sometimes “intervene” or file evidence if they have a sufficient interest.
- Judgment: The judge delivers a judgment, which may include quashing the decision, requiring the decision-maker to reconsider, or – in rare cases – granting a mandatory order.
A key feature of judicial review is its focus on procedural fairness. If, for instance, a planning inspector failed to give adequate reasons for their decision, or if a necessary consultation was omitted, the court may intervene even if the ultimate decision would otherwise be sound.
Case Studies: Judicial Review and Planning Appeal in Action
To understand how judicial review functions, consider the following hypothetical examples:
- Case 1: Procedural Breach – A local authority grants planning permission for a new supermarket without notifying nearby residents or considering their representations. A resident, having no right of planning appeal against a grant of permission, seeks judicial review. The court finds that the local authority failed to comply with statutory consultation requirements and quashes the decision.
- Case 2: Misapplication of Policy – A planning application is refused, and the applicant appeals. The Planning Inspectorate upholds the refusal but is challenged via judicial review because they misunderstood the local plan. The High Court agrees and orders the Inspector to reconsider.
- Case 3: No Right of Appeal – A council issues an enforcement notice but the recipient was not given the opportunity to make representations. With no right to a planning appeal on procedural issues, the recipient applies for judicial review. The court finds for the claimant and the enforcement decision is set aside.
Role of Third Parties and Community Groups
One aspect where judicial review plays a vital role is enabling third parties, such as community groups or non-applicants, to challenge planning decisions. Unlike planning appeals, which are mainly accessible to applicants subjected to a refusal or adverse conditions, judicial review provides broader standing. Provided they have a sufficient interest, affected individuals or organisations can seek judicial scrutiny over land use decisions that may impact public rights, environmental interests, or community welfare.
Campaign groups routinely use judicial review to challenge significant infrastructure developments (such as airports, roads, or housing estates), particularly where they believe environmental assessments are lacking or statutory processes have been breached. Notable examples include judicial review challenges to major government infrastructure policies or the grant of permission for controversial developments.
The Importance of Timeliness and Procedural Compliance
Judicial review is governed by certain procedural requirements, chief among them being strict time limits and the need to exhaust alternative remedies like planning appeals. The impetus is on claimants to act quickly and make their submissions within weeks, not months. The courts will only extend time limits in exceptional circumstances, reinforcing the need for prompt legal advice.
Another aspect is the need for claimants to demonstrate they have used any right of planning appeal before approaching the courts. If an appeal was available but not pursued, judicial review is unlikely to be entertained. Conversely, where the law provides no right of appeal, judicial review becomes a crucial safeguard.
Remedies and Outcomes
If a challenge is successful, the usual remedy is for the challenged decision to be quashed, placing the parties back in the position before the decision was taken. The planning authority or inspectorate must then reconsider the application, this time in compliance with applicable legal procedures. Importantly, even after a judicial review, the authority might still reach the same substantive decision after correcting any procedural flaws.
The court may also grant declaratory relief, clarifying the legal position, or – in very rare cases – require an authority to take specific steps. Damages are almost never available in planning judicial reviews.
The Impact on Applicants: Weighing Planning Appeal Against Judicial Review
For applicants, understanding the distinction and sequencing between planning appeals and judicial review is essential. It is common for applicants to pursue a planning appeal first, as this allows for a merits-based reconsideration of their proposal. Only where procedural unfairness or legal missteps may have occurred, or in cases where no appeal is available, will judicial review become the appropriate route.
In practice, the decision between pursuing a planning appeal or initiating judicial review requires careful legal assessment. A planning appeal allows the decision to be reconsidered on its planning merits — including policy interpretation, design considerations, environmental impacts, and housing supply arguments. It provides a second opportunity to persuade an independent inspector that permission should be granted.
Judicial review, however, is concerned with legality rather than planning judgment. It may be appropriate where:
- A decision-maker misunderstood or misapplied statutory policy.
- There was a failure to provide adequate reasons.
- Mandatory consultation requirements were not followed.
- Environmental Impact Assessment (EIA) obligations were overlooked.
- Bias or predetermination affected the decision.
Applicants must be cautious. Judicial review carries cost risk and strict time limits, and courts will not entertain challenges that merely disagree with planning conclusions. A poorly framed claim can be refused permission at the first stage.
Equally, there are strategic circumstances where judicial review can be decisive — particularly in large-scale developments, infrastructure schemes, or where policy interpretation has wider implications beyond a single site.
Judicial Review of Planning Inspector Decisions
Judicial review is not limited to local authority decisions. Decisions made by the Planning Inspectorate — including appeal decisions — may also be challenged in the High Court.
Where a planning inspector:
- Misinterprets the development plan,
- Fails to properly apply the National Planning Policy Framework,
- Provides legally inadequate reasoning,
- Or commits procedural unfairness during a hearing or inquiry,
the court may quash the inspector’s decision.
However, the threshold is high. The court will not interfere simply because another inspector might have reached a different conclusion. The focus remains firmly on legal error, not planning disagreement.
This reinforces the importance of presenting legally robust submissions at appeal stage. Once a decision is issued, options narrow significantly.
Strategic Considerations in Planning Litigation
Judicial review in the planning system is often described as a remedy of last resort — but it is also a powerful accountability mechanism.
For developers and landowners, it may:
- Correct flawed refusals.
- Clarify policy interpretation.
- Protect substantial investment.
- Prevent unlawful conditions or enforcement action.
For community groups, it ensures that statutory duties — particularly environmental and consultation obligations — are respected.
Yet planning litigation requires careful cost-benefit analysis. The compressed timetable, procedural complexity, and potential for adverse costs orders mean early specialist advice is essential.
Judicial Review as a Critical Safeguard in the Planning System
Judicial review in the planning system plays a vital constitutional role. While planning appeals reassess the merits of development proposals, judicial review ensures that public authorities — including local planning authorities and the Planning Inspectorate — act lawfully, fairly, and within their statutory powers.
It is not a mechanism for rearguing planning merits. Instead, it is a focused legal challenge concerned with:
- Procedural compliance
- Proper interpretation of planning policy
- Lawful exercise of statutory powers
- Respect for environmental and human rights obligations
Given the strict six-week time limit for most planning judicial review claims and the complexity of High Court procedure, early specialist advice is essential.
Whether you are:
- A developer challenging an unlawful refusal,
- A landowner facing defective enforcement action,
- A promoter seeking to quash an inspector’s flawed decision,
- Or a third party concerned about procedural irregularity,
strategic legal analysis at the outset can determine whether judicial review — or a planning appeal — is the appropriate course.
