Factual and Procedural Background
The notice party, Louth County Council, requested a determination from An Bord Pleanála ("ABP") regarding the proposed development of the N52 Ardee Bypass, involving the construction of a 4.5km road with associated infrastructure including junctions, bridges, pedestrian and cycle facilities, drainage, landscaping, and lighting. ABP made two decisions dated 19 October 2021: directing the local authority not to prepare an Environmental Impact Assessment ("EIA") Report and not to prepare a Natura Impact Statement ("NIS"). The applicants, Friends of Ardee Bog, sought to challenge these decisions by judicial review.
The local authority had previously advanced bypass proposals since 1999, with approvals and compulsory purchase orders issued in the early 2000s. In 2018/2019, hedgerow clearing occurred along the proposed northern route, which the applicants contend amounted to rural restructuring without appropriate EIA or Appropriate Assessment ("AA"). The applicants argue that retrospective consent or consideration of these prior works was required.
The case engages EU environmental directives, including the Habitats Directive, Birds Directive, and EIA Directive, and involves consideration of the statutory framework under the Roads Act 1993, Planning and Development Regulations 2001, and related statutory instruments. The local authority submitted AA and EIA screening reports prepared by an environmental consultancy, which concluded no significant effects on European sites. An Inspector's report supported ABP's determinations.
The applicants challenge the adequacy of these assessments, the failure to require an EIA or NIS, and allege procedural and substantive errors. ABP and the respondents defend the decisions, asserting jurisdictional correctness and sufficiency of the assessments. The court granted leave to proceed with the judicial review on specified grounds.
Legal Issues Presented
- Whether ABP erred in directing the local authority not to prepare an Environmental Impact Assessment Report under s.50(1)(b) of the Roads Act 1993 in respect of the proposed Ardee Bypass development.
- Whether ABP erred in directing the local authority not to prepare a Natura Impact Statement pursuant to regulation 250(3)(a) of the Planning and Development Regulations 2001.
- Whether prior hedgerow clearing by the local authority constituted rural restructuring requiring EIA or AA, and whether ABP failed in its remedial obligations under EU law by not considering such prior works.
- Whether ABP had jurisdiction to make the determinations under the relevant statutory provisions.
- Whether the assessments complied with the requirements of the Habitats Directive, Birds Directive, and EIA Directive, including the application of best scientific knowledge and precautionary principle.
- Whether the decisions adequately specified reasons and considered relevant environmental factors including flood risk guidelines and in-combination effects.
Arguments of the Parties
Applicants' Arguments
- The removal of hedgerows by the local authority in 2018/2019 amounted to rural restructuring requiring an EIA, which was not conducted.
- The decision of ABP was irrational and circumvented EU law by ignoring the prior works and failing to require appropriate assessments.
- The local authority cannot implement only part of development consent; it should be all or nothing.
- ABP was obliged to consider prior works under its remedial obligations and should have required a full EIA and AA.
- ABP failed to take into account relevant selection criteria specified in Annex 3 of the EIA Directive.
- ABP failed to consider the impacts of constructing only one leg of the bypass on traffic flow and environmental effects.
- There was insufficient information on the file, including lack of detailed conservation objectives, management plans for Special Protection Areas ("SPAs"), and absence of consideration of bird disturbance and flood risk.
- The AA screening was invalid as it did not comply with best scientific knowledge, lacked expert evidence, and failed to consider in-combination effects properly.
- The decisions contravened statutory requirements by failing to specify main reasons, features of the development, or measures to avoid significant adverse environmental effects.
- The decision to issue AA screening without an application for development consent was challenged as lacking jurisdiction.
Respondents' Arguments
- The applicant failed to provide sufficient particulars, and their challenge was vague, hypothetical, and unsubstantiated without expert evidence.
- ABP did not have jurisdiction over rural restructuring, which is regulated by the Minister for Agriculture under statutory instruments.
- The prior clearing of hedgerows was not part of the development consent before ABP, and no retrospective consent was sought or identified.
- ABP had authority under regulation 250(3)(a) to make the determinations requested by the local authority.
- The AA and EIA screenings were conducted in accordance with relevant legislation and EU law, including application of the precautionary principle and best scientific knowledge.
- The Inspector's report and local authority screening documents provided adequate reasons and assessments to support ABP's decisions.
- The flood risk guidelines were referenced and considered as appropriate, and the guidelines do not constitute binding specific planning policy requirements in this context.
- The absence of detailed conservation objectives or management plans does not invalidate an AA screening.
- Public participation is not mandated in the circumstances of this screening determination.
- The decisions did not grant development consent and thus did not trigger the full requirements of the EIA Directive regarding public participation.

Court's Reasoning and Analysis
The Court carefully examined the statutory framework, relevant EU directives, and the factual matrix surrounding the proposed development and prior activities. It observed that the local authority's prior hedgerow clearing constituted rural restructuring regulated under specific agricultural environmental regulations, falling within the Minister for Agriculture's remit rather than ABP's jurisdiction.
The Court found that ABP had jurisdiction under the Planning and Development Regulations 2001, specifically regulation 250(3)(a), to make the requested screening determinations, either expressly or by necessary implication, supported by Supreme Court authority.
The Court reviewed the evidence and assessments before ABP, including the comprehensive AA and EIA screening reports prepared by the local authority's consultants and the Inspector's detailed report. It found these assessments to have been conducted in accordance with best scientific knowledge and applying the precautionary principle.
The Court noted that the applicants failed to provide expert evidence or sufficiently particularized grounds to demonstrate manifest error, irrationality, or procedural unfairness in ABP's determinations. The absence of detailed conservation objectives or management plans for the SPAs did not invalidate the AA screening, consistent with EU Commission guidance and recent case law.
The Court also found that the decisions adequately stated reasons, referencing the Inspector's report and supporting documentation, fulfilling legal requirements for transparency and intelligibility.
Regarding flood risk and in-combination effects, the Court accepted that relevant guidelines were considered appropriately in the context of the screening determinations, which were not decisions granting development consent but preliminary assessments.
Overall, the Court concluded that ABP's decisions were lawful, reasonable, and supported by the material before it, and that the applicants had not met the burden to overturn them.
Holding and Implications
The Court REFUSED THE RELIEF OF CERTIORARI, thereby upholding ABP's decisions of 19 October 2021 directing the local authority not to prepare an Environmental Impact Assessment Report or a Natura Impact Statement in respect of the proposed Ardee Bypass development.
The Court declared that prior to the publication of the Stabannan and Braganstown conservation objectives, the State respondents failed to have in place sufficiently specific conservation objectives for the Stabannan-Braganstown SPA, contrary to EU law; this issue was resolved by consent.
The decision confirms the division of jurisdiction between ABP and the Minister for Agriculture regarding rural restructuring and clarifies that ABP's screening determinations under the Planning and Development Regulations are lawful and do not require detailed conservation objectives or management plans to be in place.
No new precedent was established beyond the application of existing principles, and the direct effect is to affirm ABP's authority and methodology in environmental screening for local authority own developments under the relevant statutory and EU frameworks.
