requiring accommodation. Future plans for the sites were, as at March 2023, inchoate.
Moreover, it was envisaged that the future plans would be subject to a separate planning
consent process. The references relied on by the Claimants in the emails of officials to
‘handling’ questions about the duration of the use of the sites reflected the, then,
uncertainty as to the future.
Application of legal principles to the evidence
94. Turning then to apply the legal principles to the assessment of the evidence.
95. Both the environmental consultants instructed on behalf of the Home Office and the
Planning Response Unit at the Department for Levelling Up, Housing and Communities
proceeded on the basis the proposed development was a temporary 12 month project.
The decision on the project, including its length, is a matter of judgement for the
decision maker, subject to judicial review on the usual public law grounds (Ashchurch).
96. The formal planning document may not necessarily circumscribe the project
(Ashchurch). However, on the facts of the present case, the Class Q route was seen as
a ‘stand-alone’ or discrete solution to the urgent difficulties faced by the Home Office
in light of the Secretary of State’s statutory duty to accommodate asylum seekers. It
was being pursued by the Home Office independent of any prospect of it continuing
beyond 12 months, albeit it was considered likely that longer use of the sites would be
required. The Secretary of State was aware that it might be necessary to decommission
the sites at the end of the 12 month period if planning permission had not been obtained
by then but this was a risk she was willing to take for the benefits afforded by the 12
month permission. Where a development is justified on its own merits and would be
pursued independently of another development, this may indicate that it constitutes a
single individual project that is not an integral part of a more substantial scheme (R
(Wingfield) v Canterbury County Council at §64).
97. The EIA Directive and the jurisprudence of the European Court of Justice recognise
that it is legitimate for different development proposals to be brought forward at
different times, even though they may have a degree of interaction, if they are different
“projects” (R (Larkfleet) v South Kesteven DC [2016] Env LR 4 at §37). The threshold
for irrationality in the making of such a judgement is a difficult obstacle to surmount
(see e.g. Newsmith Stainless Ltd v Secretary of State for the Environment, Transport
and the Regions [2017] P.T.S.R. 1126).
98. I accept the submission on behalf of the Claimants that the duration of use of the site is
relevant for EIA screening and there is evidence to indicate that the use was likely to
continue beyond 12 months. It is one of the criteria for screening set down in Schedule
3 of the EIA Regulations. However, it is also apparent from the evidence that no
decision about the duration of use of the sites had been made by late March 2023.
Moreover, Schedule 3 of the Regulations refers not only to the duration of the
development but to other factors relevant to screening about which there is no
discussion in the contemporaneous Home Office decision making material. These other
factors include the size and design of any future development; the intensity and
complexity of the development; the magnitude and spatial extent of the impact. The
precise location, nature, type, and scale of any potential future use had not been
discussed. It could involve a different type of development (e.g. involving the
construction of permanent buildings, rather than temporary) and/or a different nature of
