Reaffirming Local Authority Control under Schedule 17: Hillingdon v HS2 Ltd – A New Precedent in Planning Law

Introduction

The case of London Borough of Hillingdon Council, R (on the application of) v. High Speed Two (HS2) Ltd ([2020] EWCA Civ 1005) represents a pivotal moment in the interplay between national infrastructure projects and local planning authorities in England and Wales. The central issue revolves around the High Speed Two (HS2) project, a major high-speed railway initiative designed to link London with the West Midlands.

At the heart of the dispute were the procedural obligations under Schedule 17 of the High Speed Rail (London West Midlands) Act 2017, which delineates the responsibilities of HS2 Ltd, the nominated undertaker, and local planning authorities like the London Borough of Hillingdon Council ("the Appellant"). The London Borough of Hillingdon Council challenged HS2 Ltd's application for plans related to the Colne Valley Viaduct South Embankment wetland habitat ecological mitigation, asserting that HS2 Ltd had failed to provide adequate information necessary for a thorough local planning evaluation.

This commentary delves into the comprehensive judgment delivered by the England and Wales Court of Appeal, examining the legal principles established, the reasoning applied, and the broader implications for future planning law and large-scale infrastructure projects.

Summary of the Judgment

The Court of Appeal delivered its judgment on July 31, 2020, addressing the appeal brought by HS2 Ltd against the decision of the London Borough of Hillingdon Council to refuse approval of its plans for ecological mitigation works. The initial refusal was based on HS2 Ltd's purported failure to supply sufficient information and evidence to enable the Council to perform its statutory duty under Schedule 17.

The central legal query was whether Schedule 17 allowed HS2 Ltd to circumvent providing necessary information by relying on its contractual obligations and guidance documents to conduct future investigations. The Court held that Schedule 17 imposes an exclusive duty on local authorities to evaluate the impact of development proposals. It concluded that HS2 Ltd could not delegate or abrogate this duty through contractual agreements or guidance documents. Consequently, the Council was within its rights to refuse the application due to the inadequacy of information provided, thereby reaffirming the significant role of local authorities in the planning approval process.

The Court quashed the Decision of the Secretaries of State, remitting the matter for reconsideration in light of the judgment, effectively bolstering the authority of local planning bodies against overarching national projects.

Analysis

Precedents Cited

The judgment references several key precedents that shape the landscape of planning law and the balance of power between national undertakers and local authorities. Notably:

Grampian Regional Council v City of Aberdeen District Council (1984): Established the principle that planning conditions related to future events must be rational and fair, ensuring they do not render the primary approval meaningless.
British Railways Board v Secretary of State for the Environment and Others [1993]: Reinforced the necessity for planning conditions to be reasonable and related directly to the development permitted.
Alison Hook v Secretary of State for Housing, Communities and Local Government and Surrey Heath Borough Council [2020]: Clarified the validity of planning conditions, emphasizing that they must serve a planning purpose, relate fairly to the development, and be reasonable.

These precedents collectively underscore the judiciary's commitment to ensuring that planning permissions and conditions remain meaningful and enforceable, preventing authorities from imposing arbitrary or redundant requirements.

Legal Reasoning

The Court's reasoning centered on the interpretation of Schedule 17 of the High Speed Rail (London West Midlands) Act 2017. The key points include:

Exclusive Duty of Local Authorities: Schedule 17 confers explicit responsibilities upon local planning authorities to evaluate the impact of HS2's development proposals, especially concerning ecological and archaeological interests.
Non-Delegable Obligations: The Court emphasized that the duty to assess impact is non-delegable, meaning HS2 Ltd cannot offload this responsibility onto local authorities or shift it through contractual clauses.
Inadequacy of Guidance Documents: Guidance and Environmental Minimum Requirements (EMRs) provided by the Secretary of State do not override statutory duties. They serve as supplementary materials to guide authorities but cannot negate the primary obligations set forth in Schedule 17.
Requirement for Adequate Information: HS2 Ltd is mandated to furnish sufficient information to facilitate the local authority's evaluation. Failure to do so obligates the authority to refrain from making an approval decision until such information is provided.
Procedural Fairness: The Court highlighted the necessity for transparency and accountability in decision-making, ensuring that local authorities are not forced into procedurally deficient positions where they cannot perform their duties effectively.

By meticulously dissecting the statutory language and scrutinizing the interplay between legislative intent and operational processes, the Court reinforced the primacy of local planning authorities in safeguarding local interests even within the framework of expansive national projects.

Impact

The Court of Appeal's decision has profound implications for future infrastructure projects and the authority of local planning bodies:

Strengthening Local Authority Powers: The judgment reasserts the significant evaluative role of local authorities in the planning process, preventing national undertakers from undermining local scrutiny through procedural maneuvers.
Clarification of Schedule 17 Obligations: It provides a clearer interpretation of Schedule 17, delineating the boundaries of HS2 Ltd's duties and reinforcing the necessity for complete information submission.
Precedent for Judicial Review: The case serves as a reference point for judicial reviews involving the balance of power between national projects and local planning controls, ensuring that statutory duties are honored over contractual and procedural guides.
Guidance for Future Project Submissions: National undertakers must ensure comprehensive and timely information provision in line with statutory requirements, aligning their submission processes with the detailed expectations of local authorities.

Overall, the decision fortifies the framework ensuring that major infrastructure developments do not eclipse local environmental and planning considerations, promoting a balanced approach between national ambitions and local stewardship.

Complex Concepts Simplified

Schedule 17 of the High Speed Rail (London West Midlands) Act 2017

Schedule 17 is a statutory provision that governs the planning approval process for HS2 Ltd, the entity responsible for developing the HS2 railway project. It delineates how HS2 Ltd interacts with local planning authorities when seeking approval for specific development actions, particularly those affecting local environments and communities.

Environmental Minimum Requirements (EMRs)

EMRs are documented standards set by the Secretary of State for Transport, outlining the environmental and archaeological protection measures that HS2 Ltd must adhere to during the development process. These requirements are designed to minimize ecological and historical impacts arising from construction activities.

Nominated Undertaker

The nominated undertaker refers to HS2 Ltd, the body designated by the Secretary of State to execute the HS2 project. This entity is responsible for coordinating with local authorities and ensuring compliance with statutory and contractual obligations.

Grampian Conditions

Grampian conditions refer to planning conditions tied to specific events or actions that must occur for a development to proceed. Named after the case Grampian Regional Council v City of Aberdeen District Council (1984), these conditions ensure that certain prerequisites are met before development can commence.

Judicial Review

Judicial review is a legal process whereby courts examine the lawfulness of decisions or actions made by public bodies, such as local councils or government departments. In this case, the Court of Appeal conducted a judicial review of the Secretary of State's Decision supporting HS2 Ltd's appeal against the Council's refusal.

Conclusion

The Hillingdon v HS2 Ltd case marks a significant reinforcement of the authority of local planning bodies within the framework of expansive national infrastructure projects. By meticulously upholding the duty of local authorities to receive comprehensive and adequate information for their evaluative roles, the Court of Appeal has ensured that local environmental and archaeological concerns retain their due consideration.

This judgment not only clarifies the boundaries and responsibilities outlined in Schedule 17 but also serves as a safeguard against the potential erosion of local planning controls by national undertakers. It underscores the necessity for transparent, cooperative processes between national projects and local authorities, ensuring that development does not come at the expense of local interests and statutory obligations.

Moving forward, this precedent will guide both national undertakers and local planning authorities in their interactions, fostering a balanced approach that respects both national development goals and local stewardship. It exemplifies the judiciary's role in interpreting and upholding legislative frameworks to maintain equilibrium between broader infrastructural ambitions and localized concerns.
