Appellants
against
THE SCOTTISH MINISTERS
Respondents
______________
Appellants: J de C Findlay QC, Colquhoun; Shepherd & Wedderburn LLP
Respondents: McKay QC, N McLean (sol adv); Scottish Government Legal Directorate
14 September 2021
Introduction
[1]
This is an appeal, under section 239 of the Town and Country Planning (Scotland)
Act 1997, against the respondents' refusal of an appeal against a refusal of planning
permission for an energy-from-waste installation at Carnbroe, North Lanarkshire. The
respondents had decided that they, rather than a reporter appointed by them, would
2
determine the appeal. The reporter, and the officials who were advising the respondents,
had recommended that the appeal be allowed. On 18 May 2020 the responsible Minister
emailed his officials that he was "not minded to accept the recommendation" for four
reasons. The appellants contend that only one of these reasons was reflected in the ultimate
decision letter of 3 November 2020. They say that the operative decision was made for the
four reasons; three of which were unlawful. The respondents do not disagree that those
three reasons may have been flawed, but they maintain that, in the absence of any challenge
to the reasons given in the decision letter, the appeal is irrelevant.
The application
[2]
The site consists of 3.6 hectares on the north side of the A8. The eastern boundary is
the railway line between Motherwell and Coatbridge. Since 2014, under a planning consent
granted on appeal on 17 May 2011, the appellants have operated a waste management
facility on the site. The site is identified as an existing waste management facility in the
North Lanarkshire Local Development Plan (see North Lanarkshire Council v Scottish Ministers
2013 SCLR 142). In 2018, planning permission was granted for a 400 dwelling residential
development on the other side of the railway line. The boundary of the existing residential
area in South Carnbroe is 200m from the north-east corner of the site.
[3]
The main features of the existing facility are 30m-high buildings and two 27m
ventilation stacks. The appellants' new application, for what they termed alterations to the
existing permission, involved a change in the use of the site to the processing only of pre-
treated residual waste. The new buildings would be closer to the existing and prospective
residential areas; less than 100m from the latter. There would be one 80m high ventilation
stack. The maximum waste processed per annum would increase from 24,000 to 204,000
3
tonnes. Left over waste, which would be sent to landfill (ie ash and metals), would be
reduced from 31% to between 5 and 8%.
Planning Policy
[4]
Scottish Planning Policy provides (para 191) that planning authorities should
consider the need for buffer zones between houses and waste management facilities. As a
guide, a buffer of 250m for the type of facility envisaged is recommended. For new
installations, local authorities should (para 188) determine whether the development would
constitute an appropriate use of land; leaving the regulation of permitted installations to the
Scottish Environment Protection Agency.
[5]
Policy 11 of the strategic development plan (the Clydeplan, 2017) states that, in order
to meet the targets which are set by the respondents' Zero Waste Plan, waste management
facilities "will generally be acceptable subject to local considerations" on industrial land and
on sites on which there already are or were such facilities. Policy EDI3C of the North
Lanarkshire Local Development Plan (2012) contains similar provisions. Policy DSP4 states
in broad terms that any development should be in keeping with the existing visual amenity
of the area. Criterion 3f requires that the development should integrate successfully into the
local area and avoid harm to the neighbouring amenity.
The decision
[6]
Contrary to their planning officials' recommendations, the Council refused the
application on the grounds of air pollution and visual intrusion. The appellants appealed to
the respondents. The respondents directed that the appeal should be determined by
4
themselves (1997 Act, Sch 4, para 3(1)). A reporter was appointed to make a
recommendation (para 3(7)).
[7]
The reporter's recommendation, in his report of 25 November 2019, was to allow the
appeal. He regarded the application as a new one, rather than a variation of the existing
permission. It had to be determined in accordance with the development plan (ie the
Clydeplan and the LDP). The reporter reasoned that the fact that the site was allocated on
the LDP as an existing waste management facility was a powerful factor in the proposal's
favour. In relation to the site's location, there was significant support for it in Policy 11 of
the Clydeplan and Policy EDI 3C of the LDP. The reporter noted the genuine concerns of
the local residents about health and air quality. He held, however, that air quality and
health impacts were within acceptable limits and would, in any event, be monitored by
SEPA, who had not objected to the proposal.
[8]
The reporter concluded that the impact on the local landscape was not significantly
detrimental. There would nevertheless be important adverse visual effects. These would be
most notably for the occupiers of the planned residential development, which would be only
around 100m away, and persons travelling on both the M8 and the A8. That was a material
consideration under reference to the guideline buffer of 250m in paragraph 191 of SPP. The
proposal was contrary to criterion 3f of Policy DSP4 of the LDP, but the reporter's overall
judgment was that the development plan supported the principle of the development and
that was the more powerful factor.
[9]
On 7 May 2020, the respondents' planning officials submitted the report to the
Minister for Local Government, Housing and Planning, along with an invitation to agree
with the reporter's recommendation to allow the appeal. On the following day, the
Minister's Private Secretary replied to the officials stating that the Minister had noted the
5
submission and wished to discuss the matter with them at a scheduled meeting on 13 May.
What was discussed at that meeting is not disclosed. On 18 May, the Minister's Private
Secretary wrote to the officials stating that the Minister was:
"... not minded to accept the recommendation for the following reasons:
1.
This is not a variation on the previous application in his opinion, but
is so materially different that it is a new application
2.
An 80 metre high chimney stack will dominate the surrounding area
and is a huge difference from 27 metre stacks
3.
Having a chimney stack only 100 metres from the proposed housing is
unacceptable and goes against planning policy
4.
This is not an energy from waste plant, as while there is electricity
generation proposed, there is nothing within the application to use the
residual heat through a district heating scheme or for industrial use".
[10]
On 28 October 2020, the planning officials submitted a new recommendation to the
Minister to refuse the appeal. A draft decision letter was attached for his approval. The
purpose of the new recommendation was to provide:
"... a follow up submission given your previous advice rejecting the reporter's
recommendation that the above appeal be allowed and that permission should be
granted. We have considered the issues afresh and now seek your agreement to the
attached draft decision letter."
The Minister agreed with the recommendation to refuse planning permission.
[11]
The decision letter, dated 3 November 2020, intimated that the respondents had
disagreed with the reporter's recommendation. They had identified four main issues: the
principle of the use of the site for an energy-from-waste plant; air quality, emissions and
public health; landscape and visual impact; and the proposal's benefits. They agreed with
the reporter that the appellants' application was to be treated as a new proposal. It did have
development plan support. The respondents accepted all of the reporter's conclusions
6
regarding air quality, emissions and public health, and the benefits of reducing landfill and
renewable energy.
[12]
The reason for disagreeing with the reporter was that the respondents placed more
weight on the development's non-compliance with Policy DSP4 of the LDP. Adverse visual
impacts significantly and demonstrably outweighed the support from other provisions of
the development plan and the other benefits of the proposal. DSP4 required that the
development should relate well to the surrounding area and avoid adverse impact on
existing or proposed properties through loss of amenity. Four hundred houses, which
would be only 100m from the ventilation stack, were planned. Existing houses were 350m
away. The reporter had recognised that the distance from the proposed housing would be
significantly less than the 250m guideline buffer, although it was recognised this was a
factor to be considered on its merits and on a case by case basis. The facility's prominent
industrial features would be seen from, and would be out of keeping with, the anticipated
residential development. The ventilation stack would detract from the visual experience of
road users on one of central Scotland's most important transport corridors. This impact
would be high because of the volume of traffic. For these reasons, the respondents
concluded that the significant adverse visual effects on residential and local amenity made
the proposal unacceptable and non-compliant with the development plan.
Submissions
Appellants
[13]
There were two main submissions in support of the appeal. First, the Minister's
decision had been taken on 18 May on the basis of a combination of four reasons; three of
7
which were unlawful. Secondly, if the decision had been taken on 28 October, it was
unlawful as material facts and/or considerations were not taken into account.
[14]
The purpose of the submission to the Minister on 28 October, and the draft decision
letter, was to put into effect the Minister's decision of 18 May. The letter provided a detailed
justification which had not been found in the email of 18 May. The respondents' officials
had not drawn the Minister's attention to, or advised him of the illegality of, or otherwise
provided guidance on, the three unlawful reasons.
[15]
Three of the reasons were unlawful. Whether the application was a new one, or a
variation of an existing permission, was irrelevant. The reporter had characterised the
application in the same way as the Minister, but recommended allowing the appeal. The
Minister did not suggest that any different planning issues arose. If the Minister was to be
taken to be indicating that that was an issue, that would result in unfairness as the
appellants had not been offered an opportunity to address the point.
[16]
SPP (para 191) did not say that a distance of 100m was impermissible. It was a
guideline only. The Minister was entitled to disagree with the reporter's judgment on
amenity, but was wrong in taking the view that the proposal was thereby contrary to SPP.
The Minister was not entitled to depart from the reporter's determination that the
ventilation stack was within permissible limits.
[17]
It was incorrect to say that the appellants' facility was "not an energy from waste
plant". Use was not of the essence of an energy-from-waste facility. Such usage may be
installed in addition to, or instead of, electricity generation capacity.
[18]
If the operative decision had been contained in the letter of 3 November, it would
have been taken in ignorance of material facts and/or without regard to material
considerations. The Minister failed: adequately to consider whether the decision letter
8
reflected his own reasons for refusing the appeal; and to reconsider that decision and/or
unlawfully delegated his decision making powers to officials.
[19]
Officials were entitled to take decisions in the name of their minister (Carltona v
Commissioners of Works [1943] 2 All ER 560), but this decision purported to have been taken
by the Minister. The knowledge and expertise of officials may be imputed to a minister who
was taking decisions under a delegated statutory power (Bushell v Secretary of State for the
Environment [1981] AC 75, at 95), but that general principle did not apply where the minister
himself made the decision (R (National Association of Health Stores) v Department of Health
[2005] EWCA Civ 154, at paras 33 and 72). The Minister's ignorance could not be cured. The
careful drafting of the decision letter, which was not itself susceptible to successful
challenge, could not cure an unlawful decision.
[20]
The Minister did not require to have read all of the relevant papers in deciding the
appeal, but, where a departmental summary, upon which he may otherwise have
legitimately relied, failed to apprise him of a material fact which he was bound to consider,
he could not be taken to have been aware of that fact because of his officials' awareness
(Minister for Aboriginal Affairs v Peko-Wallsend (1986) 66 ALR 299 at 302; R (Transport Action
Network v Secretary of State f or Transport [2021] EWHC 2095 (Admin) at paras 60 - 79). The
Minister had not been made aware that his earlier views were flawed. That was obviously a
material consideration for him to take into account (R (Friends of the Earth) v Heathrow Airport
[2021] PTSR 190, at paras 119 and 120), but he could not have done so. Officials had, on
instruction, produced a coherent decision letter rejecting the appeal, but the basis for that
instruction had been flawed.
9
Respondents
[21]
The appeal did not question the validity of the decision of 3 November 2020 on a
challengeable basis under section 239 of the 1997 Act. The appellants did not contend that
there was anything unlawful about that decision. The email of 18 May 2020 did not
represent a decision of the respondents. What was being challenged were reasons which did
not form part of the decision. The appellants' analysis, of what were said to be the true
reasons, was irrelevant to the decision actually taken. The documents and correspondence,
which were relied upon by the appellants, constituted administrative work in advance of the
decision letter. The Minister did not fail to reconsider matters, nor did he unlawfully
delegate. The respondents decided to refuse the appeal, having been provided with advice
that there were sound planning reasons for so doing.
[22]
The Minister had been supported in his understanding of the planning issues by the
collective knowledge, experience and expertise of his officials (Bushell v Secretary of State for
the Environment at 95). The amount of information required in order to determine a
planning application was a question of planning judgment (Simson v Aberdeenshire Council
2007 SC 366, at 379). Although fuller reasons were required for disagreeing with a
considered and reasoned recommendation (Horada v Secretary of State for Communities and
Local Government [2016] EWCA Civ 169, at paras 36 and 37; North Lanarkshire Council v
Scottish Ministers 2017 SC 88, at paras [27]-[44]), the respondents were entitled to reject the
reporter's and the officials' recommendations. The respondents differed from the reporter
on: the weight to be attached to the visual impact of the development; whether the proposed
development was, on balance, in accordance with the development plan; and the extent to
which conflict with the development plan was outweighed by other material considerations.
The decision letter contained adequate reasons for disagreeing with the reporter.
10
[23]
The respondents agreed with the reporter that this was an application for a new
planning permission. That was not, however, a basis on which the appeal was refused.
They accepted the reporter's conclusion that the proposal received considerable in -principle
support from the development plan. They did not treat the application or appeal as
incompetent, but determined it on its merits. The decision accepted that what was proposed
was an energy-from-waste plant and that it drew support from the relevant provisions of the
development plan, but that it was contrary to its provisions on visual impact. The latter
consideration significantly and demonstrably outweighed the others.
Decision
[24]
The process which was followed by the respondents is not capable of successful
challenge. A reporter recommended allowing the appeal and granting planning permission.
In doing so, he treated the application as if it were for a new facility, although the existing
facility being on the site was a powerful factor in favour of the proposal. Air quality and
health impacts were within acceptable limits. There would be adverse visual effects on the
proposed new housing and on the A8 and M8; the former being in conflict with SPP's
guideline buffer zone. The proposal conflicted with LDP policy DSP4 but, overall, the
support from the development plan in general outweighed the concerns about visual
impact.
[25]
The respondents' planning officials sent the report to the Minister and, in essence,
echoed its terms in inviting the Minister to agree with the reporter's recommendation. The
details of exactly what happened between then and the issue of the decision letter in
November 2020 are unclear, but nothing which has been said by the appellants detracts from
the simple fact that the respondents' decision, and the reasons for it, are contained
11
exclusively in that decision letter. The reasons are not challenged. On that simple basis the
appeal must be refused.
[26]
The appellants recovered the email of 18 May from the Minister's Private Secretary to
the respondents' planning officials. This set out the Minister's thinking at that time;
presumably following the scheduled meeting. It gives four reasons behind that thinking;
that the Minister was "minded" (inclined) to refuse the appeal. That may be interesting
background, but these were not the reasons why the Minister, as the delegate of the
respondents, did in fact refuse the appeal several months later. The decision followed the
second submission by the officials which had been drafted having "considered the issues
afresh". No doubt the officials would have taken into account the content of the email, and
any discussions which occurred before or after that email, but their ultimate
recommendation and reasons were clear. In authorising the issue of the decision letter, the
Minister must be taken to have accepted that new recommendation and approved of the
reasons for it. In the absence of an allegation of bad faith or some form of deception on the
part of the Minister or his officials, which the appellants did not advance, the decision letter
must be taken to represent the whole basis for the decision taken. There is no basis for a
contention that the Minister's reasoning at the time of the decision letter was not that
contained in that letter.
[27]
The Minister may have had four reasons in mind at some point earlier in the process,
but those did not form part of the eventual decision. There is nothing unusual about that. If
one or more of these reasons was considered unlawful or otherwise bad, the Minister's
officials might have been expected to advise him to that effect, and the Minister would have
had to put them out of mind. Alternatively he could have ignored the advice and insisted in
it being in the decision letter. The alternative was not adopted. The evolution of ministerial
12
thinking, such as that seen in the present case, is part of the ordinary process of dialogue,
consideration and reconsideration, that often takes place within government as views pass
back and forwards between ministers and their officials. Eventually the minister reaches a
decision. That final decision cannot normally be picked apart later by reference to some
aspect of the dialogue which led up to it.
[28]
The appellants submit that the Minister was not told that three of the four reasons
were unlawful. There is simply no basis for this proposition. It is speculation and
contradicted by the terms of the second submission from the respondents' officials which
attached the draft decision letter. That letter contained one fundamental reason for refusal
of planning consent. That was that the respondents disagreed with the reporter in balancing
the adverse visual impact with the other factors for and against the proposal. The Minister
endorsed the refusal of the appeal for that reason and that reason alone. There is no ground
for a contention that, in so doing, the Minister took into account any irrelevant consideration
or failed to have regard to a relevant one. The considerations are those, and only those, in
the decision letter itself.
[29]
The appeal is refused.
