An Taisce - The National Trust for Ireland v Minister for Housing Local Government and Heritage & Ors [No. 6] (Approved)

Factual and Procedural Background

The Applicant challenged the validity of Ireland's Fifth Nitrates Programme ("Fifth NAP") under Directive 91/676 and related implementing measures, as well as the validity of Commission Implementing Decision 2022/696, which permits a derogation allowing livestock manure application exceeding 170 kg nitrogen per hectare annually on relevant farms. The challenge arose in the context of environmental and agricultural regulatory compliance concerning nitrate pollution control.

The procedural history includes multiple public consultations initiated by the Respondent Minister for Housing, Local Government and Heritage regarding the NAP, with submissions made by the Applicant during these consultations from 2020 to 2022. Ireland requested an extension of the derogation in October 2021, which was granted by the Commission in 2022.

The judicial review proceedings commenced on 31 May 2022, with leave granted on 5 December 2022. Notice parties representing agricultural interests were joined and generally supported the State's position. The referring court identified nine questions of EU law for preliminary ruling by the Court of Justice of the European Union ("CJEU"), eight concerning interpretation and one on validity. The court stayed the proceedings pending the CJEU's ruling on these questions.

Legal Issues Presented

1. Whether Article 5(1) and/or 9(1)(b) of, and paragraph (f) of Annex I to, Directive 2001/42 preclude treating material assets as outweighing other environmental factors in environmental assessments, or require selecting the option with the least adverse environmental effects as the preferred outcome.
2. Whether Article 5(1) and/or 9(1)(b) of, and paragraph (h) of Annex I to, Directive 2001/42 require that alternatives be identified, described, and evaluated in a comparable way for the purposes of assessment under Article 3(1) of that Directive.

Arguments of the Parties

Applicant's Arguments

• Material assets cannot be treated as a factor that outweighs other environmental factors; they are one among several environmental considerations to be assessed equally.
• There is no requirement to select the option with the least environmental effects unless all relevant factors have been lawfully assessed.
• The Environmental Report improperly used "material assets" to refer to economic implications for farmers and the agri-food industry, which are non-environmental considerations and should not influence environmental assessment outcomes.
• All reasonable alternatives must be assessed to comparable levels of detail and quality, ensuring fair evaluation as required by Directive 2001/42 and supported by European Commission Guidance and case law from England and Wales.
• The Court of Appeal's approach suggesting less rigorous assessment of alternatives compared to the preferred option is erroneous.

Respondents' Arguments

• The SEA Directive imposes procedural obligations only and does not require selecting the least environmentally harmful option; discretion lies with competent authorities to balance environmental, policy, and economic considerations.
• Article 5(1) requires an environmental report to identify, describe, and evaluate likely significant environmental effects and reasonable alternatives but does not mandate equal weighting or selection based solely on environmental factors.
• Commission Guidance confirms the environmental report is an iterative tool supporting sustainable decision-making but does not impose substantive substantive criteria for choice of alternatives.
• Regarding assessment of alternatives, the Directive envisages only one draft plan or programme to be fully developed and consulted upon; reasonable alternatives need not be subject to full strategic environmental assessment to the same extent as the preferred option.
• Case law and the Directive's text support a disjunctive approach to assessment of alternatives and the draft plan, allowing differing levels of detail.
• Recent Advocate General opinions support that the SEA Directive does not require the preferred option to be assessed less thoroughly but do not impose equal assessment requirements on all alternatives.

Notice Parties' Arguments

• The notice parties, representing agricultural associations, agreed with the Respondents' submissions on both legal issues.

Court's Reasoning and Analysis

The court analyzed the interpretation of Directive 2001/42, focusing on Articles 5(1), 9(1)(b), and Annex I paragraphs (f) and (h), in the context of Ireland's Nitrates Action Programme and Commission derogations allowing higher livestock manure application.

Regarding the first question, the court noted that the Directive prescribes procedural obligations for environmental assessment but does not mandate substantive outcomes or require selection of the option with the least adverse environmental effects. The balancing of environmental factors, including material assets, is a matter of discretion for competent authorities. This interpretation aligns with the CJEU judgment in An Bord Pleanála and Others (Site de St Teresa's Gardens) and recognizes that "material assets" are one environmental factor among others without inherent precedence.

Concerning the second question, the court considered the requirement to assess reasonable alternatives comparably. The Applicant argued for equal and full assessment of all alternatives, citing European Commission Guidance and UK case law. The Respondents contended that the Directive envisages a single draft plan or programme subject to full assessment and consultation, with alternatives assessed less extensively. The court favored the Applicant’s interpretation, emphasizing that the Directive and supporting guidance require that the likely significant effects of the plan and its reasonable alternatives be identified, described, and evaluated in a comparable manner. The court found that the assessment here did not fully meet that standard, as the preferred option was analyzed in more detail than alternatives.

The court acknowledged the complexity of balancing procedural obligations with practical considerations in strategic environmental assessment but underscored the importance of comparable evaluation to ensure informed and transparent decision-making.

Holding and Implications

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

The court noted that the substantive determination of the judicial review proceedings would be adjourned pending the CJEU's judgment. The referral underscores the significance of clarifying the interpretation of Directive 2001/42 in relation to environmental assessments of plans and programmes affecting agricultural practices and environmental protection.

The decision directly affects the parties by pausing the national proceedings and seeks authoritative EU guidance, but it does not establish new precedent at the national level. The outcome will provide clarity on procedural and substantive requirements for environmental assessments in Ireland and potentially across Member States.
