“It needs to be borne in mind that the EIA process is intended to be an aid to efficient and inclusive decision making in special cases, not an obstacle-race” (Carnwath LJ as he then was, in R (Jones) v Mansfield District Council (Court of Appeal, 16 October 2003).
The courts continually tell us this, despite so many professionals, politicians and objectors still treating the process of environmental impact assessment as some duller version of Gladiators.
Perhaps if we heeded this message the Government wouldn’t need to tie itself up in knots trying to replace environmental impact assessment and strategic environmental assessment with this still vague idea of environmental outcomes reports (reported by Planning Resource this week as now not likely to progress until 2025!).
I thought about this when looking at this week’s (free subscription) Town Library weekly judgments update – it contains amongst other things two Court of Appeal judgments dealing with particular assessment issues that regularly arise – as to cumulative effects and as to defining the “project“.
First we have R (Substation Action Save East Suffolk v Secretary of State (Court of Appeal, 17 January 2024) which concerned a challenge to development consent orders for the construction of the East Anglia One North and East Anglia Two offshore wind farms with associated onshore and offshore development.
The case has attracted some interest in relation to the court’s determination that the sequential test in relation to flood risk does not apply to the risk of flooding from surface water:
“The relevant provisions of EN-1, the Framework and the PPG do not require an applicant for development consent to demonstrate that whenever there is a risk of flooding from surface water there are no other sites reasonably available where the proposed development could be located in an area of lower surface water flood risk. The risks of flooding from surface water are to be taken into account when deciding whether to grant development consent under section 104 of the 2008 Act. The way in which account is to be taken of that risk raises issues of planning judgment in the application of the relevant provisions of the policies. The judge was correct in her interpretation of the policy and in finding that there was no irrationality or other public law error in the way in which the first respondent dealt with this issue when granting development consent.”
However, it was also interesting to read the the court’s consideration of the extent to which the potential effects on the environment arising from other projects need to be taken into account as cumulative effects. The appellant contended that “certain projects (known as the “Nautilus” and “Eurolink” schemes) have been identified as projects which could connect with the new National Grid substation. An assessment of the effect of those two projects was included in an Extension Appraisal document supplied by the second and third respondents. The appellant contends that the first respondent should have taken that information into account when deciding whether to make the development consent orders but he did not do so.” The reference in Schedule 4 of the EIA Regulations that the environmental statement must describe the likely significant effects of the development, including “the cumulation of effects with other existing and/or approved projects” is regarded as somewhat of a minefield.
The court ducked whether these potential future projects were to be regarded as “existing or approved” because the decision maker lawfully deferred consideration of the cumulative effects on the basis that there was not yet any adequate information on which a cumulative assessment could be based. “Such information as was available on the likely effects of other potential projects was not relevant to the assessment of the significant effects of the projects forming part of the applications for development consent in the present case.”
EIA pragmatism exhibit #1.
Secondly we have R (Together Against Sizewell C) v Secretary of State (Court of Appeal, 20 December 2023) which concerned a challenge to a development consent order for the proposed Sizewell C nuclear power station. The challenge related to Habitats Regulations Assessment rather than environmental impact assessment but the principles read across. It was argued that the Secretary of State was wrong in law to treat the permanent supply of water to Sizewell C as not being part of the same project as Sizewell C for the purposes of carrying out an “appropriate assessment” under the Habitat Regulations (“Ground 1”) and that even if the Secretary of State was right to regard the permanent water supply as a separate project, he erred in failing to carry out a cumulative assessment of its effects together with those of Sizewell C itself, as per the Habitats Regulations (“Ground 2”).
Lazily I’m now just going to quote from our Town Library case summary:
“Ground 1
The Court dismissed Ground 1. The Court accepted, firstly, that there was no material difference between the meaning of a “project” under the Habitat Regulations and environmental impact assessment regulations and, secondly, that the principle adopted in previous cases that determining the nature and scope of a project, including whether two or more developments are to be regarded as one project, is a matter for the decision-maker to determine, which can only be subject to judicial review by the court on the grounds of irrationality or other unlawfulness. The Court, although seeking not to be prescriptive, endorsed the factors identified in the Wingfield case as capable of influencing this exercise of judgment.
The Court found no irrationality or any other unlawfulness in the Respondent’s decision, noting not only that he was entitled to reach this decision, but the Court would have reached the same conclusion.
It should also be noted that the Court rejected an argument that the Respondent unlawfully avoided appropriate assessment under the Habitats Regulations and saw the approach taken as a realistic and legitimate use of the “staged approach” previously approved in case law.
Ground 2
Ground 2 was dismissed by the Court for a number of reasons. These reasons included that it is well established that the consideration of cumulative impacts arising from a subsequent development that is still inchoate may be deferred to a later consent stage. Given that insufficient information was available as to the water supply, the decision to defer assessment by the Respondent was rational and lawful.
The Court rejected the argument that no proper assessment of the impacts would be carried out at the later stage because the construction of Sizewell C would result in the inevitable approval of the water supply proposal. There was no evidential basis for assuming that regulators would fail to carry out their statutory duties to assess the adverse effects of the water supply. The Court also rejected the argument that deferral was irrational because of a risk of Sizewell C not being operational in the absence of a water supply, as there was a reasonable level of certainty a permanent water supply would be provided and further the alternatives would still be subject to appropriate assessment.
Accordingly, the appeal was dismissed.”
