The European Court of Justice is certainly turning the screws this year via various cases in relation to the Republic of Ireland, with now three rulings against its Planning Board, An Bord Pleanála. Following People Over Wind (see my 20 April 2018 blog post EU Court Ruling: Ignore Mitigation Measures In Habitats Screening) and Grace, Sweetman (see the second half of my 18 August 2018 blog post What Is Mitigation?) we now have Holohan (CJEU, 7 November 2018).
People Over Wind has removed the ability for the competent authority to screen out the need for appropriate assessment, under the Conservation of Habitats Regulations 2017, on the basis that a significant effect on a Special Protection Area or Special Area of Conservation is unlikely, where that conclusion is reliant on proposed mitigation measures. The result has been far more projects and plans requiring appropriate assessment to ascertain that they will not adversely affect the integrity of the relevant SPA or SAC.
Grace, Sweetman has removed the ability for the competent authority to reach a conclusion at appropriate assessment stage that there will be no adverse effect on integrity, where mitigation measures are relied on that in reality amount to compensatory measures for the loss of habitat.
1. […] an ‘appropriate assessment’ must, on the one hand, catalogue the entirety of habitat types and species for which a site is protected, and, on the other, identify and examine both the implications of the proposed project for the species present on that site, and for which that site has not been listed, and the implications for habitat types and species to be found outside the boundaries of that site, provided that those implications are liable to affect the conservation objectives of the site.
2. […] the competent authority is permitted to grant to a plan or project consent which leaves the developer free to determine subsequently certain parameters relating to the construction phase, such as the location of the construction compound and haul routes, only if that authority is certain that the development consent granted establishes conditions that are strict enough to guarantee that those parameters will not adversely affect the integrity of the site.
If you are relying on an appropriate assessment in relation to a project or plan, I suggest that you urgently check that it addresses these three requirements. An decision taken in reliance upon an appropriate assessment which does not cover off these points will be susceptible to legal challenge. If caught at the right time, deficiencies should be able to be addressed by some extra work. But it will be too late to rectify matters once the appropriate assessment is reached and the decision taken.
These CJEU rulings are unambiguous in their stated conclusions on the law, very different from our common law approach.
“Where environmental principles are contained in specific pieces of EU legislation, these will be maintained as part of our domestic legal framework through the retention of EU law under the EU (Withdrawal) Bill. Any question as to the interpretation of retained EU law will be determined by UK courts in accordance with relevant pre-exit CJEU case law and general principles, subject to the other exceptions and restrictions within the Bill. For example, CJEU case law on chemicals, waste and habitats includes judgments on the application of the precautionary principle to those areas. This will therefore be preserved by the Bill“.
As set out in that blog post, we are still waiting for the draft Bill, required by section 16 of the EU (Withdrawal) Act to be published by Boxing Day 2018, that will set out the environmental principles to be applied post Brexit and the body that will enforce them.
What we now have seen of course is the draft withdrawal agreement published on 14 November 2018. Who knows whether it will be concluded but it envisages that the CJEU will continue to have jurisdiction in any proceedings brought against the UK during the transition period to 31 December 2020.
– Non-regression in level of environmental protection subsisting at the end of the transitional period.
“The United Kingdom shall ensure that administrative and judicial proceedings are available in order to permit effective and timely action by public authorities and members of the public against violations of its laws, regulations and practices, and provide for effective remedies, including interim measures, ensuring that any sanctions are effective, proportionate and dissuasive and have a real and deterrent effect.
Professor Colin Reid’s 15 November 2018 blog post Environmental Commitments in the Withdrawal Agreement is a very good commentary on all of these provisions.
Finally, fabulous timing on the part of UKELA to have secured for next week’s annual Garner lecture Professor Juliane Kokott, Advocate General at the CJEU (who has been at the centre of so much EU case law, including the People Over Wind and Holohan cases referred to above). It will be fascinating to hear her perspective.
PS David Elvin QC has since reminded me that the CJEU also on 7 November handed down its judgment in the Dutch Nitrogen Deposition case, which also contains important rulings in relation to appropriate assessment, for instance the extent to which agricultural activities amount to a “project”, as well as the extent of certainty required if conservation measures are to be relied upon as mitigation. See James Maurici QC’s blog post.
