NPF4 Renewable Energy Support Does Not Displace Geographically-Specific LDP “Countryside Around Towns” Policies: Policy 11’s Balance Is Proposal-Impact Focused, While Plan-Wide Balancing Sits Under Policy 1

Court: Court of Session, Inner House (First Division)
Citation: [2026] CSIH 40
Date: 14 August 2026
Procedure: Appeal under s 239 Town and Country Planning (Scotland) Act 1997

1. Introduction

This appeal concerned the refusal of planning permission for a large anaerobic digestion and biomethane facility (with carbon capture) proposed by Acorn Bioenergy Limited on land at Longmorn, near Elgin. The application was refused by Moray Council, and a Scottish Ministers’ appointed reporter dismissed the appeal. The company then appealed to the Inner House.

The decisive policy conflict was between:

  • strong national support for renewable/low-carbon and negative emissions technologies in National Planning Framework 4 (NPF4), especially Policy 11, and the “significant weight” direction in Policy 1; and
  • the local, geographically-specific restriction on development in designated Countryside Around Towns (CAT) areas in the Moray Local Development Plan 2020 (LDP), especially Policy EP4 (and also EP6 on settlement boundaries).

The appellant argued, in substance, that the reporter wrongly treated “the principle of development” as the key issue and thereby (i) elevated EP4 into an effective embargo on renewable energy development, and (ii) failed to conduct the full “balancing exercise” required by NPF4 Policy 11 (including socio-economic benefits, biodiversity, landscape/visual mitigation, circular economy, and “just transition” considerations).

The court’s decision is significant because it clarifies (a) how NPF4 Policy 11 is to be read alongside geographically-specific LDP constraints, (b) where plan-wide balancing sits in NPF4, and (c) the limited role of the court on a s 239 appeal where the challenge is, in reality, to planning judgment and weight.

2. Summary of the Judgment

The Inner House refused the appeal. It held that:

  • The court’s role is supervisory: it does not re-run the planning merits or re-weight factors (paras [40]–[41]).
  • The reporter was entitled to identify the key issue as the acceptability of the site “in principle” under the development plan, and to treat other matters as secondary where they did not affect that overarching question (paras [42]–[48]).
  • Read fairly and as a whole, the reporter did not misdirect himself, ignore relevant considerations, or misunderstand the meaning/effect of NPF4 or the LDP (paras [49]–[52]).
  • Crucially, the court endorsed the reporter’s approach that the “balancing exercise” within NPF4 Policy 11 relates to assessing the proposal’s detailed impacts, not to a plan-wide override of other development plan policies; the wider balancing across the plan is “provided for” by NPF4 Policy 1 (significant weight to climate crisis) (para [50]).
  • The reporter was entitled to conclude that the development conflicted with the settlement strategy embodied in LDP Policy EP4, and that the emissions savings and other advantages did not justify setting aside that long-term strategy at this location (paras [51]–[53]).

3. Analysis

3.1 Precedents Cited

Tesco Stores v Environment Secretary [1995] 1 WLR 759

The court relied on Tesco for the orthodox proposition that the interpretation of policy is for the decision-maker, and that questions of planning judgment and weight are generally not for the court. The Inner House cited Lord Keith (at 764H) and Lord Hoffmann (at 780H) to reinforce the boundary between:

  • legal error (misdirection, leaving out a material consideration, irrationality), and
  • disagreement on merits/weight (not reviewable).

This framing was decisive: it set the lens through which the appellant’s detailed criticisms were treated as, essentially, an attempt to re-argue the planning balance (paras [40]–[41]).

J29 (Scotland) v Scottish Ministers [2025] CSIH 17

The court cited J29 (Scotland) to the same effect: the Inner House will not re-evaluate a judgment concerning the application of planning policies to the facts (para [40]). The citation anchored the court’s approach in recent domestic authority and emphasised continuity: s 239 appeals are not a merits review.

3.2 Legal Reasoning

(a) The statutory decision framework: “plan-led” decision-making

The court emphasised that the reporter required to determine the appeal in accordance with the development plan unless material considerations indicated otherwise, reflecting the familiar s 25(1) Town and Country Planning (Scotland) Act 1997 duty (para [42]).

Within that plan-led framework, the court accepted that the decisive question could legitimately be expressed as whether the location was acceptable “in principle” under the development plan (para [42]). The appellant’s submission that this formulation “sidelined” NPF4 was rejected as an unduly narrow reading of the decision.

(b) How NPF4 Policy 11 interacts with geographically-specific LDP policies

The core interpretive point endorsed by the court was the reporter’s distinction between:

  • the internal balancing within NPF4 Policy 11 (used to assess the proposal’s detailed impacts and mitigation), and
  • the broader, plan-wide balancing exercise across potentially competing development plan policies, for which NPF4 Policy 1 provides the “significant weight” direction on climate considerations (para [50]).

On this approach, Policy 11’s supportive stance does not operate as a self-contained “code” that displaces geographically-specific LDP constraints (such as CAT designations). Instead:

  • Policy 11 supplies strong support “in principle” for low-carbon/negative emissions technologies; but
  • site acceptability still falls to be tested against the development plan as a whole, including place-specific settlement strategy policies.

The court therefore rejected the appellant’s attempt to treat EP4 as “superseded” by Policy 11; EP4 remained operative and could legitimately be decisive where conflict was found (para [51]).

(c) “Principle of development” and the role of “secondary” issues

A recurring theme in the appellant’s case was that the reporter’s identification of the “principle” as the key issue caused him to diminish factors such as:

  • economic benefits (NPF4 Policy 11(c));
  • biodiversity (NPF4 Policy 3) and nature-crisis elements of Policy 1;
  • landscape/visual mitigation and other detailed effects (Policy 11(e));
  • circular economy and just transition.

The court’s answer was practical rather than formalistic: the reporter did consider these matters, but was entitled to conclude that they did not alter the overarching “in principle” site acceptability conclusion (paras [43]–[48]). The Inner House treated this as a legitimate planning judgment about relevance and weight, not a legal error.

(d) The CAT policy (EP4) as settlement strategy, not a mere landscape test

The reporter (and the court) treated EP4 as part of a plan-led settlement strategy restricting development pressure around key towns, not merely as an invitation to a case-by-case landscape and visual assessment. The court accepted that the proposed development conflicted with EP4 and EP6, including because it would be “visually detached” from Elgin in a more open countryside setting (para [44]).

Importantly, the court also endorsed the reporter’s reasoning that the appellant had not shown that the CAT location was the only viable option or that there was a “clear and exceptional need” for the plant to be at the particular Longmorn site (para [51]). That finding fortified the conclusion that climate/energy benefits did not compel departure from settlement strategy at that location.

(e) The court’s treatment of “how much emissions saving is enough?”

The appellant criticised the absence of an explained threshold for emissions savings sufficient to overcome EP4. The court did not accept that such quantification was legally required. Instead, it treated the reporter’s conclusion—“not sufficient to overcome the long-term settlement strategy”—as a classic planning judgment on weight and balance, insulated from appellate interference absent legal error (paras [53]–[54]).

3.3 Impact

  • Reinforced survivability of place-specific LDP constraints in the NPF4 era: Even where NPF4 strongly supports a class of development (here, renewable/low-carbon with carbon capture), geographically-specific LDP designations (like CAT/settlement boundaries) can remain determinative where conflict is found.
  • Structural clarification of NPF4 balancing: The judgment supports a “two-level” approach:
    • Policy 11: impacts/mitigation assessment for energy proposals; and
    • Policy 1: plan-wide balancing instruction (significant weight to climate crisis) when reconciling policy tension across the development plan.
    This is likely to be cited in future disputes where applicants argue NPF4 renewable energy support operates as an override.
  • Litigation discipline on s 239 appeals: The decision is a reminder that attempts to re-argue weight—especially by close textual critiques of individual paragraphs—will struggle where the decision “read as a whole” demonstrates awareness of relevant policies and an intelligible balance.
  • “Need for this site” evidential focus: Where a proposal conflicts with a restrictive designation, applicants can expect increased scrutiny of alternative sites and the strength of site-specific locational need (even for net-zero aligned infrastructure).

4. Complex Concepts Simplified

4.1 “Section 239 appeal” (what the court can and cannot do)

A s 239 appeal is not a re-hearing on the merits. The court checks legality: Did the reporter misunderstand policy, ignore something legally relevant, take account of something irrelevant, give inadequate reasons, or reach an irrational conclusion? It does not decide whether it would have granted permission.

4.2 “Plan-led” decision-making and “development plan as a whole”

Decision-makers must decide in accordance with the development plan unless material considerations indicate otherwise. The “development plan” is not a single policy: it is a composite of NPF4 and the LDP. Apparent tensions are resolved through judgment and balance across the plan.

4.3 “Inconsistency” vs “incompatibility” between NPF4 and LDP

The case illustrates that a local policy not expressly accommodating a type of development (e.g., renewable energy) is not necessarily “incompatible” with NPF4 support for that development. Compatibility is assessed in context: supportive national policy can coexist with place-specific local restrictions, leaving a tension to be balanced rather than an automatic override.

4.4 “Principle of development” vs “detailed impacts”

“Principle” refers to whether the type of development is acceptable in that location under the plan (e.g., whether a CAT designation allows it). “Detailed impacts” are matters like noise, landscape/visual effects, biodiversity measures, traffic, and mitigation. The reporter can treat the former as primary if it is determinative of the plan position.

5. Conclusion

[2026] CSIH 40 confirms that strong NPF4 support for renewable and negative-emissions technologies does not, by itself, displace geographically-specific LDP settlement strategy policies such as Moray’s CAT designation. The Inner House endorsed a structured reading of NPF4 in which Policy 11 addresses the balancing of an energy proposal’s detailed impacts, while wider plan-wide reconciliation of competing policies is guided by Policy 1’s instruction to give significant weight to the climate crisis. Above all, the case reiterates that challenges framed as disputes about weight and planning judgment will not succeed on a s 239 appeal absent a clear legal error.
