Anonymised Summary of Legal Opinion

Factual and Procedural Background

This appeal concerned the relationship between planning control under the Town and Country Planning Act 1990 ("TCPA 1990") and the licensing of caravan sites under the Caravan Sites and Control of Development Act 1960 ("the 1960 Act"). The central factual matrix in the opinion may be summarised as follows (all party and location identifiers have been anonymised).

• The Appellant (the operator of a caravan site, hereafter "Company B") acquired a caravan site ("the site") in 2016 near The City in The State. The local planning authority and licensing authority for the area is Company A.
• The site lay in a sensitive landscape and conservation context and was subject to a historic tree preservation order. The site also benefited from two historical planning permissions (1952 and 1966) permitting up to 60 caravans, the 1966 permission containing a condition restricting the siting of caravan standings to identified areas on an attached plan.
• In 1968 a site licence under the 1960 Act was granted; it referenced the earlier planning permissions and included a condition requiring hardstandings for caravans and specifying the layout areas (A–H) on an attached plan.
• In March 2017 Company B unlawfully felled protected trees and carried out substantial engineering works including reprofiling terraces, constructing retaining walls, a roadway and 27 concrete hardstandings. The Council issued enforcement notices in March 2019 (one notice concerned operational development: the engineering works and hardstandings; the other concerned a material change of use) and a tree replacement notice in January 2021.
• Company B appealed the enforcement notices and sought a CLOPUD (certificate of lawfulness) and other relief. A Planning Inspector (on 20 August 2021) quashed one enforcement notice (material change of use) and granted the CLOPUD as to the lawful use for certain static caravans, but upheld the enforcement notice directed at the operational development (the engineering works and hardstandings) and refused planning permission for those works. The High Court dismissed Company B's s.289 challenge to that decision in July 2022.
• On 26 April 2022 Company A granted a new site licence under the 1960 Act allowing only three caravans in locations said not to interfere with the tree replacement notice or remedial steps required by the enforcement notice. Company B appealed that licensing decision to Tribunal A (the First-tier Tribunal Property Chamber). Tribunal A varied the licence to allow 18 caravans and held that the licensing decision should not have regard to the enforced planning baseline (the enforcement notice) but should have regard to the tree replacement notice in imposing conditions.
• Company A appealed Tribunal A's decision to Tribunal B (Upper Tribunal, Lands Chamber). Tribunal B allowed Company A's appeal, holding that Tribunal A was wrong to disregard the outcome of the enforcement notice appeal and that site-licensing conditions must be consistent with the planning baseline. Tribunal B directed inclusion of additional pitches that lay outside the enforcement notice area.
• Company B appealed to the court whose opinion is summarised here. The court was therefore required to resolve the legal question of how and to what extent a site-licensing decision under the 1960 Act must take into account planning determinations and enforcement notices under the TCPA 1990.

Legal Issues Presented

1. Whether, and to what extent, a licensing authority determining an application under the 1960 Act must disregard "purely planning considerations" when deciding whether and on what conditions to grant a caravan site licence.
2. Whether a site licence can lawfully authorise the siting of caravans (or require operational development such as hardstandings) in locations that are inconsistent with the planning permissions upon which the licence application depends, or that are inconsistent with the planning determinations made through the statutory enforcement process under the TCPA 1990.
3. Whether the grant of a site licence (and the consequential Class B permitted development right under the GPDO 2015) can, in effect, negate or circumvent a final planning determination that operational development already carried out was unlawful and must be removed.

Arguments of the Parties

Appellant's Arguments

• The licensing authority under the 1960 Act must disregard a final determination under the TCPA 1990 that certain engineering operations (hardstandings) were a breach of planning control; licensing decisions should not be influenced by "purely planning considerations".
• Company B argued that the licensing authority could grant a licence subject to a condition requiring hardstandings for mobile homes; once attached, that condition would create a permitted development right (the Class B right in the GPDO 2015) allowing the carrying out of development required by the site licence. Company B said that this would mean future reinstatement of hardstandings could be achieved by relying on that permitted development right even if an enforcement notice required removal.
• Company B maintained it had to be able to rely upon the existing 1952 and 1966 permissions for the use as a caravan site and that permitted development rights are prospective and therefore an enforcement notice cannot prevent future reliance on those rights.
• Company B submitted that conditions on a site licence may only be imposed for site-licensing purposes and not for purely planning purposes, and that the enforcement notice matters concerned planning rather than site-licensing questions.

Company A's (Local Authority's) Arguments

• Company A argued that Tribunal A erred in law by deciding that the enforcement notice and the planning baseline were irrelevant to the site-licensing decision. Tribunal B's earlier UT decision had already held that the FTT should not have decided to disregard the outcome of the enforcement notice appeal.
• Company A submitted that the site licence must be in harmony with the planning permissions on which the licence depends (s.3(3) of the 1960 Act), and that it would be irrational and unlawful for a licensing decision to authorize works that are inconsistent with the planning baseline determined under the TCPA 1990.
• Company A emphasised that if a site operator wishes to depart from planning permissions, the appropriate route is an application under the TCPA 1990 (including s.73 or a new application), not a site-licensing decision that would effectively enlarge planning rights or circumvent enforcement.

Court's Reasoning and Analysis

The court's analysis proceeded by identifying the statutory framework and established authorities governing the interaction between the planning regime (TCPA 1990 and the GPDO 2015) and the site-licensing regime (the 1960 Act). The court focused on statutory provisions and established case-law principles and applied them step-by-step to the facts of the present case:

1. Precondition in s.3(3) of the 1960 Act: A site licence may be issued only if the applicant is "entitled to the benefit of a permission for the use of the land as a caravan site granted under Part III" otherwise than by a development order. The court emphasised that express planning permissions and their conditions form the planning baseline for any licence determination and must be read as an integral whole.
2. Statutory effects of enforcement notices and reinstatement: The court explained s.171A, s.172, s.173, s.174, s.180 and s.181 of the TCPA 1990. It stressed that an enforcement notice has continuing, prospective effect (s.181) and that reinstatement of development removed in compliance with an enforcement notice is itself likely to be a contravention unless authorised by a planning permission.
3. Role and scope of the Class B permitted development right: The Class B right in the GPDO 2015 (development required by the conditions of a site licence) only arises consequential upon the grant of a site licence containing conditions requiring development. The court rejected the appellant's submission that a licensing decision could simply authorise, or validate retrospectively, previously unlawful operational development by creating prospective Class B rights.
4. Harmony principle between planning permissions and licence conditions: Drawing on Crittenden, Cartledge and related authorities, the court held that site-licensing decisions must operate in harmony with, and not in conflict with, the planning permission upon which they rely. Licensing cannot be used to expand planning rights or to relax conditions of a planning permission that have been properly imposed or upheld in planning proceedings.
5. Distinction where "pure planning" considerations are irrelevant: The court acknowledged earlier authorities (Esdell, Hartnell, Babbage) that a purely planning objective cannot be used to justify licence conditions that effectively cut down existing planning rights without compensation. Those cases, however, do not support the appellant's position here because the present case involved an express planning determination (the enforcement notice appeal) concluding the operational development was unlawful and requiring removal.
6. Application to the facts: The court accepted Tribunal B's reasoning that Tribunal A erred in treating the enforcement notice and planning baseline as irrelevant. The Class B right did not, and could not, validate the past unlawful engineering operations because those operations were inconsistent with the 1968 licence layout and the 1952/1966 planning permissions as interpreted by the Planning Inspector and as upheld on judicial review. Consequently, it was permissible and necessary for the licensing authority to impose licence conditions that were consistent with the planning baseline and the enforcement notice.
7. Rejection of the appellant's irrationality argument: Company B argued it would be irrational to require compliance with an enforcement notice when future Class B rights could permit similar works. The court rejected this as incoherent because it would require licence authorities to ignore planning permissions and enforcement decisions and would allow licensing to produce Class B rights that undermine the planning regime without scrutiny—an outcome inconsistent with the statutory scheme.

Holding and Implications

Holding: The court UPHELD the decision of the Upper Tribunal and DISMISSED the appeal.

Direct consequences of the decision

• The licence decision must be made taking into account, and consistently with, the planning baseline established by the relevant planning permissions and the final decision on the enforcement notice relating to operational development.
• The Appellant failed to show that the operational development (the hardstandings and engineering works) was required by the 1968 site licence such that it fell within the Class B permitted development right; therefore that operational development remained unlawful and not validated by the licence process.
• The site licence should not authorise any plots that are the subject of the enforcement notice, except where no action under the enforcement notice is required; licence conditions must be consistent with the 1952 and 1966 permissions (including condition 2 of the 1966 permission) and with the final planning determinations made under the TCPA 1990.

Broader implications identified by the court

The court reaffirmed and applied existing principles rather than announcing a novel doctrine: licensing under the 1960 Act operates as an additional layer of control that must be exercised in harmony with the planning regime; it cannot be used to legitimize or to circumvent prior planning determinations or enforcement action. The court accepted and applied prior authorities (including Crittenden and Cartledge) to confirm that planning permissions and their conditions form the relevant planning baseline for licensing decisions, and that permitted development rights consequent upon a licence (Class B) should not be read as a tool to reverse or nullify a properly made enforcement determination.

Outcome

The appeal was dismissed. The decision of the Upper Tribunal (which allowed Company A's appeal against Tribunal A and required the licensing decision to be consistent with the planning baseline) was upheld. The Appellant's challenge to the conclusion that the operational development was not authorised by the relevant planning permissions and did not fall within the Class B right was unsuccessful.
