Secretary of State for Levelling Up, Housing and Communities v Caldwell & Anor

Factual and Procedural Background

The case concerns an appeal against an enforcement notice issued under section 172 of the Town and Country Planning Act 1990 ("the 1990 Act") by a local planning authority, Buckinghamshire Council. The enforcement notice required the cessation of residential use and the demolition of a bungalow known as "The Goose House", built without planning permission on land in the Metropolitan Green Belt near Beaconsfield. The bungalow was constructed in 2013-2014 after multiple unsuccessful planning applications by the landowner, hereinafter referred to as the First Respondent.

The Secretary of State for Levelling Up, Housing and Communities (the Appellant) appealed against a decision by an inspector to dismiss an appeal by the First Respondent against the enforcement notice. The inspector also dismissed related appeals by the First Respondent and a second respondent, a company, against refusals or failures to determine applications for certificates of lawful use or development.

The enforcement notice alleged a material change of use of the land from agricultural to residential and operational development comprising the construction of the dwelling and ancillary structures. The First Respondent appealed on multiple grounds, notably ground (d) under section 174(2) of the 1990 Act, which challenges the ability to take enforcement action due to statutory time limits.

Lieven J. quashed the inspector's decision, finding that the inspector misapplied the legal principle from Murfitt v Secretary of State for the Environment [1980] 40 P. & C.R. 254 regarding the scope of enforcement powers to require removal of operational development linked to a material change of use. The Secretary of State obtained permission to appeal this judgment.

Legal Issues Presented

1. Whether the inspector misapplied the principle in Murfitt concerning the scope of the power under section 173(4)(a) of the 1990 Act to require removal of operational development associated with a material change of use.
2. Whether the inspector's application of the Murfitt principle in this case was irrational.

Arguments of the Parties

Appellant's Arguments

• The decisive question is whether the inspector was entitled to find that the construction of the dwelling was "part and parcel" of the unlawful change of use.
• The Murfitt principle is subject to two restrictions: (1) operational development must not exceed what is integral to the material change of use; (2) removal cannot be required for works previously undertaken for lawful use. Only the first restriction is relevant here.
• The judge's limitation on the Murfitt principle lacks basis in the authorities and would lead to "useless" buildings and planning harm.
• The breach of planning control was the material change of use, and the enforcement notice aims to restore the land to its pre-breach condition, including removal of integral structures.
• The inspector lawfully concluded that the building was integral to the unauthorised use, consistent with the Murfitt principle and not Wednesbury unreasonable.

Respondent's Arguments

• An expansive application of the Murfitt principle disrupts the legislative distinction between enforcement time periods for operational development and material changes of use.
• The principle does not permit removal of operational development that is fundamental to or causative of the change of use.
• Operational development must be "ancillary" to the change of use, as emphasised in key authorities including Welwyn Hatfield Borough Council and Newbury District Council.
• The residential use did not "entail" or "result in" the construction of the dwelling; rather, the building preceded and caused the change of use.
• The inspector misunderstood the scope of the Murfitt principle, which is limited by statutory parameters and not reducible to mere planning judgment.

Court's Reasoning and Analysis

The court began by reaffirming the established principle in Murfitt that an enforcement notice requiring removal of operational development integral to an unauthorised material change of use is lawful, as it reflects the statutory remedial power in section 173(4)(a) to restore land to its prior condition. However, this principle is narrow and must operate within the statutory framework, particularly the distinct enforcement time limits set out in section 171B of the 1990 Act.

The court emphasised that operational development must be ancillary, secondary, or facilitative to the material change of use to fall within the Murfitt principle. Operational development that is fundamental to or causative of the change of use is not ancillary and thus not subject to removal under this principle. This distinction preserves the statutory four-year immunity for operational development and the ten-year limit for material changes of use.

Applying these principles to the facts, the court found that the inspector erred by misdirecting himself on the scope of the Murfitt principle. The inspector rejected the requirement that operational development be ancillary or incidental, instead accepting that it was sufficient for the development to be integral or part and parcel of the change of use. This broadened the principle beyond its legal boundaries, effectively allowing enforcement against operational development that should have been immune after four years.

The court agreed with the lower court that the construction of the dwelling was operational development fundamental to and causative of the change of use, not ancillary to it. Therefore, the inspector's decision to require removal of the building under the enforcement notice was legally flawed.

The court declined to decide on the alternative argument of irrationality given the legal error identified.

Holding and Implications

The court DISMISSED the appeal by the Secretary of State.

The direct effect is that the inspector’s decision to uphold the enforcement notice requiring demolition of the dwelling was quashed due to legal error in applying the Murfitt principle. The ruling preserves the statutory distinction between enforcement time limits for operational development and material changes of use, reinforcing that operational development fundamental to a change of use is protected by the shorter four-year enforcement immunity period.

No new precedent was set; the decision clarifies and confirms the existing legal framework and limits on the Murfitt principle’s application. The judgment also notes that forthcoming legislative changes will amend enforcement time limits but do not affect this case’s outcome.
