Judicial Review Boundaries in National Infrastructure Projects: Packham v HS2 Ltd [2020] EWCA Civ 1004

Introduction

The case of Packham v. High Speed Two (HS2) Ltd ([2020] EWCA Civ 1004) stands as a significant judicial examination of the limits of judicial review in the context of large-scale national infrastructure projects. Christopher Packham, an environmental campaigner and television personality, challenged the UK Government's decision to proceed with the HS2 high-speed railway project on environmental grounds, specifically questioning the project's alignment with the Paris Agreement and the Climate Change Act 2008. This commentary delves into the Court of Appeal's judgment, exploring its implications for future judicial interventions in politically charged and economically significant governmental decisions.

Summary of the Judgment

The Court of Appeal upheld the Divisional Court's refusal to grant permission for Mr. Packham's judicial review application against the Government's decision to continue with the HS2 project. The Divisional Court had initially dismissed the claim on the grounds of delay in filing and deemed the issues raised to fall under a "light touch" Wednesbury grounds of rationality. The Court of Appeal reinforced these findings, affirming that the Government's decision was rooted in a political judgment within a statutory framework that already encompassed comprehensive environmental assessments. Consequently, the challenge was deemed unarguable, and no new grounds were found to merit overturning the initial refusal.

Analysis

Precedents Cited

The judgment extensively references several key cases to delineate the boundaries of judicial review in matters of national importance. Notably:

Finn-Kelcey v Milton Keynes Borough Council [2009] Env LR 17: Emphasized the necessity for promptness in judicial review applications related to planning permissions.
Plan B Earth v Secretary of State for Transport [2020] EWCA Civ 214: Addressed the limits of judicial intervention in the designation of national policy statements, particularly concerning climate commitments.
R. (on the application of Assange) v Secretary of State for Foreign Affairs [2012] EWHC 3150 (Admin): Discussed the principle that courts should not weigh in on the merits of politically sensitive decisions.

These precedents collectively underscore the judiciary's restrained role in reviewing decisions that inherently involve political discretion and broad policy judgments, especially those related to national infrastructure.

Legal Reasoning

The Court of Appeal's reasoning pivots on the classification of the Government's decision as a "macro-political" judgment that warrants minimal judicial interference. Several key points emerge from their analysis:

Scope of the Oakervee Review: The panel's mandate was to conduct a cost-benefit analysis within a constrained timeframe, not to re-evaluate the comprehensive environmental assessments previously conducted for HS2 Phase One.
Statutory Framework: The HS2 project had already undergone rigorous environmental impact assessments as part of the High Speed Rail (London-West Midlands) Act 2017, satisfying legal obligations under EU and domestic laws.
Wednesbury Grounds: The court applied the traditional standard of irrationality, concluding that the Government's decision not to revisit earlier environmental assessments was reasonable and within its discretionary powers.
Promptness of the Claim: Initially, the Divisional Court found Mr. Packham's application untimely. However, the Court of Appeal recognized that promptness should be assessed based on the specific circumstances, ultimately finding the application timely.

The Court concluded that the Government's decision was informed by existing statutory processes and that any deviations or additional considerations were appropriately within the executive's discretion.

Impact

This judgment reaffirms the judiciary's limited role in intervening in high-level governmental decisions, especially those enveloped within statutory mandates and comprehensive policy frameworks. Future implications include:

Judicial Restraint: Courts are unlikely to overturn decisions on national infrastructure projects unless there is clear evidence of legal error or irrationality.
Clarification of Grounds for Review: Establishes that challenges based solely on policy disagreements or broad environmental concerns without specific legal violations are insufficient for judicial intervention.
Guidance for Applicants: Demonstrates the importance of adhering to procedural requirements and establishing arguable legal grounds when seeking judicial review of major projects.

The decision thus serves as a benchmark for assessing the thresholds required for successful judicial challenges against significant governmental undertakings.

Complex Concepts Simplified

Several intricate legal concepts underpin this judgment, warranting clarification:

Judicial Review: A legal process through which courts assess the lawfulness of decisions or actions taken by public bodies.
Wednesbury Grounds: Refers to a standard of rationality where a decision is deemed unlawful if it is so unreasonable that no reasonable authority could have made it.
Common Law Power: Authorities derived from judicial decisions rather than statutes, allowing courts to interpret laws and their applications.
Carbon Budget: A cap on the total amount of greenhouse gases the UK can emit over a specific period to meet climate targets.

Understanding these terms is essential to grasp the nuance of the court's decision, highlighting the interplay between legal standards and political discretion.

Conclusion

The Court of Appeal's judgment in Packham v. HS2 Ltd underscores the judiciary's deference to executive decisions in the realm of national infrastructure, particularly when those decisions are anchored in comprehensive statutory processes and environmental assessments. By affirming that the Government's determination to proceed with HS2 was lawful and within its discretionary powers, the court delineates the boundaries of judicial intervention, reaffirming the principle that not all policy-driven decisions are susceptible to successful judicial challenges. This case thus serves as a pivotal reference point for future litigants and policymakers navigating the complex landscape of judicial reviews related to large-scale governmental projects.
