Introduction

Corbett v Cornwall Council ([2022] EWCA Civ 1069) is a pivotal case in the realm of local planning law in England and Wales. The case centered on the interpretation and application of Policy 3 of the Cornwall Local Plan, specifically scrutinizing the meaning of the term "immediately adjoining" in the context of granting planning permission for residential development. The appellant, William Corbett, challenged the decision of Cornwall Council to grant permission for the construction of a dwelling-house and garage at Beacon House East, Trevarrian, arguing that the policy had been misapplied.

The core issues revolved around whether the council had correctly interpreted "immediately adjoining" a settlement and whether it had considered irrelevant factors in its decision-making process. The Court of Appeal ultimately upheld the lower court's decision, reaffirming the council's interpretation and application of the local plan policy.

Summary of the Judgment

The Court of Appeal dismissed William Corbett's appeal against Cornwall Council's decision to grant planning permission for the development at Beacon House East, Trevarrian. The central question was whether Policy 3 of the Cornwall Local Plan had been misinterpreted and misapplied, particularly concerning the term "immediately adjoining" a settlement.

The court concluded that the council had lawfully interpreted "immediately adjoining" in a broader sense, allowing for an evaluative judgment based on the specific circumstances of the site. The inclusion of functional relationships between the proposed development and the settlement was deemed appropriate and not an irrelevant consideration. Consequently, the court found no error in law, upholding the council's decision.

Legal Reasoning

The court's legal reasoning hinged on the flexible interpretation of planning policy language. It emphasized that terms like "immediately adjoining" should not be construed too narrowly as "contiguous" or "coterminous." Instead, such terms require an evaluative judgment based on the specific context and characteristics of the development site and the existing settlement.

The judgment highlighted that local planning authorities have the discretion to interpret policies in a manner that aligns with the broader objectives of sustainable and coherent community development. The court underscored that the inclusion of functional relationships between the development and the settlement was a legitimate consideration, not an irrelevant one.

Furthermore, the court reinforced that policy interpretations should align with the overarching goals of the local plan and should not be constrained by overly rigid definitions. This approach ensures that planning decisions remain flexible and context-sensitive, promoting sustainable development while accommodating the unique needs of each community.

Impact

The judgment in Corbett v Cornwall Council has significant implications for future planning cases, particularly regarding the interpretation of local planning policies. Key impacts include:

• Enhanced Flexibility: Reinforces the necessity for flexible interpretation of planning terms, allowing for case-by-case evaluative judgments.
• Judicial Deference: Affirms the courts' deference to local planning authorities' professional judgments in policy interpretation, provided there is no legal error.
• Policy Interpretation Standards: Sets a precedent for interpreting policy language in a manner consistent with the broader objectives of local development plans.
• Functional Considerations: Validates the inclusion of functional relationships in planning decisions, expanding the criteria beyond mere physical proximity.
• Precedential Value: Serves as a guiding case for similar disputes over policy interpretation, offering a framework for assessing the adequacy of local authority decisions.

Complex Concepts Simplified

Immediately Adjoining

The term "immediately adjoining" is pivotal in local planning policies, often determining whether a development can proceed in proximity to an existing settlement. In this case, "immediately adjoining" should not be interpreted too literally (i.e., merely touching the settlement boundary) but should allow for a broader evaluative approach that considers both physical and functional relationships.

Previously Developed Land (PDL)

PDL refers to land that has been previously used for residential purposes and is considered more sustainable for new development as it minimizes the impact on greenfield sites. In this case, the proposed development replaced an existing garage and other outbuildings, qualifying the land as PDL under Policy 3.

Evaluative Judgment

Evaluative judgment in planning involves assessing various factors and making discretionary decisions based on the specific circumstances of each case. It contrasts with rigid, formulaic decision-making, allowing for flexibility and context-sensitive outcomes.

Functional Relationship

A functional relationship refers to how a proposed development will interact with and affect the existing settlement beyond mere physical proximity. This includes considerations like the integration of services, the character of the settlement, and the overall impact on the community's functioning.

Conclusion

The Corbett v Cornwall Council case underscores the importance of flexible and context-sensitive interpretation of local planning policies. By upholding a broad and evaluative understanding of "immediately adjoining," the Court of Appeal affirmed the necessity for planning decisions to consider both physical proximity and functional integration within settlements.

This judgment reinforces the principle that local planning authorities possess the discretion to interpret policies in alignment with sustainable development goals and community needs. It also sets a clear precedent for future cases, emphasizing judicial deference to local authorities' professional judgments unless there is a clear legal error.

Overall, the decision enhances the framework within which local planning policies are applied, promoting coherent and predictable decision-making that balances development needs with the preservation of community character and environmental considerations.
