Reaffirming the Interpretation of "Openness" in Green Belt Mineral Extraction under the NPPF

Introduction

The case of Samuel Smith Old Brewery (Tadcaster) & Ors v. North Yorkshire County Council ([2020] UKSC 3) addresses a pivotal issue in the interpretation of the term "openness" within the National Planning Policy Framework (NPPF) as it pertains to mineral extraction in Green Belt areas. The core dispute centered on whether North Yorkshire County Council, acting as the local planning authority, appropriately applied the concept of openness when granting planning permission for an extension of Jackdaw Crag Quarry.

Summary of the Judgment

The High Court initially quashed the planning permission granted in January 2013 due to deficiencies in the environmental impact assessment. The Court of Appeal upheld this decision, asserting that the council had been misled by flawed advice from their planning officer, particularly concerning the "openness" of the Green Belt under paragraph 90 of the NPPF. The council appealed to the Supreme Court, arguing that the Court of Appeal misunderstood both the relevant policies and the officer's report. The Supreme Court ultimately allowed the appeal, thereby affirming the order of the High Court to dismiss the planning permission application.

Analysis

Precedents Cited

The judgment extensively references several key cases and policy documents that have shaped the interpretation of Green Belt policies:

• Redhill Aerodrome Ltd v Secretary of State for Communities and Local Government [2014]: Emphasized that the NPPF was intended to consolidate existing policies rather than introduce significant changes.
• R (Lee Valley Regional Park Authority) v Epping Forest District Council [2016]: Clarified the relationship between appropriate and inappropriate development within Green Belts.
• Europ Oil and Gas Ltd v Secretary of State for Communities and Local Government [2013]: Highlighted the special status of mineral extraction under Green Belt policies.
• Turner v Secretary of State for Communities and Local Government [2016]: Affirmed that "openness" in Green Belt is an open-textured concept influenced by multiple factors, including visual impact.

These precedents collectively underscore the judiciary's approach to balancing development needs with the preservation of Green Belt characteristics, particularly "openness."

Legal Reasoning

The Supreme Court's reasoning hinged on whether the planning officer had correctly interpreted and applied the concept of "openness" as defined in the NPPF. Lord Carnwath, delivering the judgment, examined whether visual impacts should be considered alongside spatial impacts when assessing the preservation of openness. While the Court of Appeal criticized the officer for neglecting visual impact, the Supreme Court concluded that the officer did not err in focusing predominantly on spatial factors. The judgment emphasized that "openness" under the NPPF does not explicitly mandate consideration of visual impacts unless they are so obviously material that their omission would constitute an error of law. In this case, the Supreme Court found that the visual impacts identified were not sufficiently material to invalidate the planning permission if spatial considerations were adequately addressed.

Impact

This judgment has significant implications for future planning applications involving mineral extraction in Green Belt areas. It clarifies that while visual impact is a relevant consideration, it is not an automatic requirement unless deemed clearly material. Planning authorities are thus further empowered to exercise judgment in balancing various factors influencing the openness of Green Belts. Additionally, the decision reinforces the principle that not all aspects of environmental impact need explicit consideration, provided that the overarching aims and specific provisions of the NPPF are adequately fulfilled.

Complex Concepts Simplified

Understanding "Openness" in Green Belt Policy

The term "openness" within Green Belt policies primarily refers to the prevention of urban sprawl by keeping land free from built development. It is about maintaining large areas of undeveloped land to preserve countryside character and prevent towns from merging. However, "openness" does not necessarily equate to visual aesthetics or the absence of any visual changes; it concerns more about the spatial integrity and overall lack of significant development.

Appropriate vs. Inappropriate Development

Green Belt policies classify development into two categories: appropriate and inappropriate. Appropriate developments are those that align with specific exceptions outlined in the NPPF, such as mineral extraction, provided they meet certain criteria like high environmental standards and restoration plans. Inappropriate developments are those that inherently harm the Green Belt's openness and are typically not permitted unless exceptionally justified.

Conclusion

The Supreme Court's decision in Samuel Smith Old Brewery (Tadcaster) & Ors v. North Yorkshire County Council serves as a crucial affirmation of how "openness" should be interpreted within Green Belt policies, especially concerning mineral extraction. By delineating the boundaries of where visual impact must be considered, the judgment provides clearer guidance for both planning authorities and applicants. It underscores the importance of balanced judicial oversight in planning decisions, ensuring that environmental and policy objectives are met without imposing unnecessary legal constraints. This case thus strengthens the framework within which Green Belt land is managed, maintaining its essential role in controlling urban development and preserving the countryside.
