Powergen UK Plc v Leicester City Council & Anor

Factual and Procedural Background

The appeal arises from a dispute concerning the interpretation and application of conditions attached to an outline planning permission granted by Leicester City Council ("the Authority") on 25 January 1995 for the redevelopment of a former power station site ("the Total Site") for various uses including retail and business purposes. The outline permission included conditions relating to the timing for submission of reserved matters and commencement of development, intended to comply with section 92 of the Town and Country Planning Act 1990, which prevents accumulation of unimplemented permissions.

The appellant ("Powergen") undertook significant preparatory work on the site but faced delays in submitting reserved matters within the prescribed time limits. Powergen applied to vary certain conditions, specifically to modify the requirement that all reserved matters be submitted and approved before any development could begin, proposing phased approval to allow part of the development ("Food Store Segment") to proceed independently.

The Authority refused applications to extend the time limits and to vary conditions, citing changed planning policies and concerns about piecemeal development undermining comprehensive planning of the site. Powergen appealed against the refusal relating to condition 2, which concerned the requirement for approval of reserved matters before development commencement.

Legal Issues Presented

1. Whether the reference to "the development" in condition 2 of the 1995 outline planning permission should be construed as referring to the whole development or to parts thereof, allowing phased approval and commencement.
2. Whether the dealings between the parties gave Powergen any legal rights or legitimate expectation to proceed with the Food Store Segment without further permissions.
3. The scope and limits of the powers of a local planning authority under section 73 of the Town and Country Planning Act 1990 when considering applications to vary conditions of a prior planning permission, particularly in the context of expired time limits and changed planning policies.
4. Whether it was lawful and rational for the Authority to refuse the section 73 application to vary condition 2 based on current planning policies and the expiry of time limits.

Arguments of the Parties

Appellant's Arguments

• Condition 2's reference to "the development" should be interpreted as allowing phased development, enabling reserved matters to be submitted and approved for parts of the site separately.
• The dealings and communications from the Authority's officers gave rise to a legitimate expectation that Powergen could proceed with the Food Store Segment without further permissions.
• The Authority's refusal to vary condition 2 was legally flawed because it effectively prevented implementation of a lawfully granted permission based on changed policies, which should not be a valid ground for refusal under section 73.
• Granting a new planning permission under section 73 should not restart time limits for reserved matters submission and commencement, and the Authority should not refuse permission simply because it disapproves of the development in principle.
• It was irrational to refuse the variation of condition 2 since the purpose of the condition—to secure approval of reserved matters—had been achieved for parts of the development.

Respondent's Arguments

• The reference to "the development" in condition 2 refers to the entire development as a whole, not parts, consistent with the statutory scheme under section 92.
• The officers lacked authority to create any legitimate expectation that would override statutory time limits and planning controls.
• The Authority was entitled to refuse the section 73 application because the original permission had expired, and planning policies had changed, making implementation undesirable.
• The refusal was rational and lawful, as permitting the variation would undermine the policy objective of preventing accumulation of unimplemented permissions and allow development contrary to current planning policies.

Precedent	Rule or Principle Cited For	Application by the Court
Pye v Secretary of State for the Environment [1998] 3 PLR 72	Clarification of the scope of section 73 applications as applications for planning permission considering only conditions to be varied; the Local Planning Authority must have regard to current planning policies and practical consequences when deciding such applications.	The court concurred with Sullivan J.'s reasoning that the Authority may consider the practical consequences of granting or refusing permission under section 73, including changed policies and the expiry of time limits, and that the original permission remains intact regardless of the section 73 decision.
Frost (cited, no full citation provided)	Illustration of the limited scope of consideration under section 73 depending on the nature of the condition to be varied.	The court referenced the case to support the proposition that the Local Planning Authority's consideration is confined to the conditions subject to variation, with the extent depending on the condition's nature.

Court's Reasoning and Analysis

The court examined the statutory framework of sections 91, 92, and 73 of the Town and Country Planning Act 1990, emphasizing the policy objective behind section 92 to prevent the accumulation of unimplemented planning permissions and to provide certainty for planning authorities and stakeholders.

The court agreed with the lower judge that the term "development" in condition 2 must be construed as referring to the entire development, not parts or phases, consistent with statutory requirements and the absence of any specification under section 92(5) for separate periods for parts of the development.

Regarding the alleged legitimate expectation arising from dealings between the parties, the court found no evidence that officers had the authority to bind the Authority or that Powergen had relied on such representations to their detriment.

In considering the powers under section 73, the court endorsed the view that the Authority must consider only the conditions subject to variation but may impose different or additional conditions as appropriate. The Authority must also have regard to current planning policies and material considerations at the time of the decision, including the practical consequences of granting or refusing permission.

The court rejected the appellant's argument that the Authority was precluded from refusing the application based on changed policies or expiry of time limits, holding that such considerations are material and lawful grounds for refusal under section 73. The court emphasized that permitting the variation would undermine the policy intent of sections 91 and 92 and allow development contrary to current planning objectives.

The court found no irrationality in the Authority's refusal, noting that the application to vary condition 2 was effectively an attempt to circumvent the refusal to extend time limits, which the Authority was entitled to resist.

Holding and Implications

The court DISMISSED the appeal, upholding the Authority's refusal to vary condition 2 of the 1995 outline planning permission.

This decision confirms that local planning authorities retain discretion under section 73 to refuse applications to vary conditions where the original permission has expired or where planning policies have changed, and that the statutory scheme aims to prevent piecemeal or phased implementation of outline permissions absent express provision. The ruling reinforces the importance of adhering to time limits for reserved matters and commencement of development under sections 91 and 92 and affirms that legitimate expectation cannot override statutory planning controls without clear authority and reliance.
