An Taisce - The National Trust for Ireland v Minister for Housing & Ors [No. 4] (Approved)

Factual and Procedural Background

This opinion concerns a request for a preliminary ruling regarding the interpretation of several European Directives (91/676, 92/43, 2000/60, and 2001/42) and the validity of Commission Implementing Decision 2022/696. The proceedings arise from a challenge by the Applicant to the validity of Ireland's Fifth Nitrates Action Programme ("NAP") under Directive 91/676 and related implementing measures, as well as a challenge to the validity of the Commission decision permitting a derogation allowing application of livestock manure exceeding the standard limit of 170 kg nitrogen per hectare annually on relevant farms.

The context includes Ireland's implementation of the NAP through national regulations, the role of the Minister for Agriculture, Food and the Marine as the competent authority for derogation authorisations, and the absence in practice of appropriate assessments ("AA") at the farm or individual derogation level under Directive 92/43. The Applicant contends that this results in insufficient environmental assessment of the NAP and related derogations.

Procedurally, the judicial review proceedings were initiated on 31 May 2022, with leave granted on 5 December 2022. Notice parties, including representatives of farming associations, were joined and generally supported the State's opposition. The High Court identified nine questions of EU law and referred these to the Court of Justice of the European Union ("CJEU") for preliminary ruling, staying the proceedings pending the CJEU's decision.

Legal Issues Presented

1. Whether an action programme under Article 5 of Directive 91/676 must be assessed by reference to the environmental effects of nitrate-emitting agricultural activities carried out pursuant to derogations granted under the plan, or only by reference to the protective measures included in the plan.
2. Whether, if the first question is answered negatively, the relevant EU provisions require assessment of individual derogations under domestic law where such assessments are not carried out in practice.
3. Whether assessment of a plan or programme subject to Directives 92/43 and 2001/42 must include an assessment of whether it is sufficiently rigorous to prevent deterioration of water bodies under Directive 2000/60, and whether such assessment must expressly state whether environmental objectives will be met.
4. Whether Member States must refuse to adopt a plan or programme if the protections it affords are insufficient to prevent deterioration of water bodies or jeopardise attainment of environmental objectives under Directive 2000/60.
5. Whether, if assessment of individual derogations under Directive 92/43 is not carried out in practice, the plan-level assessment must compensate by sufficiently assessing impacts on water bodies.
6. Whether a plan or programme with potential to affect water body status may be adopted only if the competent authority satisfies itself that it will not cause deterioration or compromise environmental objectives under Directive 2000/60.
7. Whether the environmental report under Directive 2001/42 must include a sufficiently detailed description of monitoring measures envisaged under Article 10 to demonstrate compliance.
8. Whether the term "material assets" in Annex I(f) of Directive 2001/42 excludes consideration of the value of such assets or broader societal and economic impacts of agricultural activities in assessing an action programme under Directive 91/676, and if so, whether such consideration is unlawful.
9. Whether Commission Implementing Decision 2022/696 is invalid if the adoption of the NAP involved breaches of Directives 92/43, 2000/60, and/or 2001/42.

Arguments of the Parties

Applicant's Arguments

• The NAP must be assessed in relation to the environmental effects of nitrate-emitting agricultural activities carried out pursuant to derogations, not solely by reference to protective measures.
• Where individual derogations are not assessed in practice, the plan-level assessment must consider the impacts of these activities to fulfill EU law requirements.
• There is an obligation to refuse adoption of a plan if its protective measures are insufficient to prevent deterioration of water bodies or to achieve environmental objectives.
• The environmental report must include detailed descriptions of monitoring measures to enable public scrutiny and demonstrate compliance with monitoring obligations.
• The term "material assets" does not exclude consideration of financial or broader societal impacts relevant to environmental assessment.
• The validity of Commission Decision 2022/696 is doubtful if the NAP was adopted in breach of EU Directives, given the decision’s reliance on a valid NAP and proper assessments.

State's Arguments

• None of the cited provisions require that an action programme be assessed by reference to the effects of nitrate-emitting agricultural activities regulated by that programme.
• There is no obligation to assess individual derogations under the Habitats Directive in practice, and failure to do so does not invalidate the upstream plan or programme.
• No obligation exists to assess the NAP under Article 4(1) of Directive 2000/60 separately from the programme of measures under Article 11.
• The environmental report under Directive 2001/42 does not require a bright-line rule as to the level of detail for monitoring descriptions; this is to be determined case-by-case under the discretion afforded by the Directive.
• The term "material assets" as interpreted in EIA context does not automatically apply to SEA; inclusion of broader societal impacts is permissible.
• Commission Implementing Decision 2022/696 remains valid even if breaches of Directives are found in the adoption of the NAP.

Notice Parties' Arguments (Representatives of Farming Associations)

• Support the State's submissions, emphasizing concerns about imposing impossible standards on agricultural activities.

Court's Reasoning and Analysis

The court undertook a detailed examination of the interplay between the Nitrates Directive (91/676), the Habitats Directive (92/43), the Water Framework Directive (2000/60), and the Strategic Environmental Assessment Directive (2001/42), as well as relevant Treaty provisions and the Charter of Fundamental Rights. It identified critical legal questions concerning the scope and content of environmental assessments required for the NAP and related derogations.

The court noted that the NAP establishes a regulatory framework permitting derogations for livestock manure application above standard limits, which are then implemented at farm level through authorisations by the Minister for Agriculture, Food and the Marine under domestic GAP regulations. However, in practice, appropriate assessments of the environmental effects of individual derogations, particularly under Directive 92/43, are not conducted at the farm level, raising concerns about compliance with EU law.

Legal analysis emphasized that assessments under Directives 92/43, 2000/60, and 2001/42 must consider not only the protective measures included in the plan but also the environmental effects of the activities regulated by the plan, including those arising from derogations. The court reasoned that limiting assessment solely to protective measures would undermine the purpose of these Directives and the Union's objective of a high level of environmental protection under Article 3(3) TEU and related Treaty provisions.

The court further reasoned that where domestic law does not ensure assessment of individual derogations, the plan-level assessment must compensate by adequately addressing the environmental impacts of the nitrate-emitting agricultural activities authorized by the plan. Failure to do so would result in unlawful adoption of the plan.

Regarding the Water Framework Directive, the court held that competent authorities must satisfy themselves that plans and programmes will not cause deterioration of water bodies or jeopardize attainment of good status objectives. This assessment must be sufficiently rigorous and clearly stated in the environmental assessment.

The court also analyzed the requirements of the SEA Directive concerning the content of environmental reports, concluding that these must include sufficiently detailed descriptions of monitoring measures envisaged under Article 10 to enable effective public participation and ensure compliance with monitoring obligations.

In relation to the term "material assets," the court found that while financial valuation of such assets may not be strictly required, the Directive does not prohibit consideration of broader societal and economic impacts in environmental assessments, provided environmental matters are also addressed.

Finally, the court addressed the validity of Commission Implementing Decision 2022/696, which grants the derogation to Ireland. It concluded that the validity of the Commission Decision depends on the valid adoption of the NAP, including compliance with environmental assessment obligations. Given the identified deficiencies in the assessment of the NAP and the lack of farm-level appropriate assessments, the Commission Decision's validity is legitimately questioned and requires determination by the CJEU.

Holding and Implications

The court ordered that the identified nine questions of EU law be referred to the Court of Justice of the European Union pursuant to Article 267 TFEU for preliminary ruling.

The substantive determination of the proceedings is adjourned pending the judgment of the CJEU.

The court emphasized that the questions referred address fundamental issues regarding the interpretation of EU environmental law and the validity of EU secondary legislation, notably Commission Decision 2022/696. The outcome of the CJEU’s ruling will have direct consequences on the legality of Ireland's Nitrates Action Programme and the associated derogation regime.

No new domestic precedent was established by this order; rather, it reflects the procedural necessity of obtaining authoritative EU interpretation on complex and significant questions of Union law raised in the context of these judicial review proceedings.
