Introduction

The case of Sweetman v. An Bord Pleanála & Anor [2021] IEHC 16 adjudicated by the High Court of Ireland on January 15, 2021, centers on a significant environmental and administrative law issue. The applicant, Peter Sweetman, sought judicial review to challenge the decision of An Bord Pleanála ("the Board") which had granted planning permission to Bradán Beo Teoranta for a development involving the abstraction of freshwater from Loch an Mhuilinn on Gorumna Island, Co. Galway. The purpose of this extraction was to facilitate the bathing of salmon in fish farms offshore, aiming to mitigate diseases such as Amoebic Gill Disease and sea lice.

The key issues revolved around the adequacy of consents under Planning and Development Regulations 2001, the correct application of the Habitats Directive concerning the Connemara Bog SAC, the necessity for an Environmental Impact Assessment (EIA) under EU law, and the Board's compliance with the Water Framework Directive (WFD) in assessing the impact on Loch an Mhuilinn.

Summary of the Judgment

The High Court, presided over by Ms. Justice Niamh Hyland, examined the challenges brought forward by Mr. Sweetman against the Board’s decision. The applicant raised four primary arguments:

• Insufficient consent from landowners affected by the water abstraction.
• Error in screening out the Connemara Bog SAC from requiring an appropriate assessment under the Habitats Directive.
• Failure to conduct a necessary Environmental Impact Assessment (EIA) in line with EU directives.
• Breach of the Water Framework Directive (WFD) due to the inability to evaluate the impact of the development on water quality and status.

After thorough examination, the court found that:

• The Board had adequately satisfied consent requirements under PDR 2001.
• The screening out of the Connemara Bog SAC was legally sound, given the distance and nature of the development.
• The applicant's argument concerning the necessity of an EIA for connected developments was inadmissible due to procedural shortcomings.
• The Board failed to comply with the WFD, as the status of Loch an Mhuilinn had not been determined by the Environmental Protection Agency (EPA), rendering the decision to grant permission incompatible with EU law.

Consequently, the High Court quashed the Board’s decision to grant planning permission for the proposed water abstraction development.

Analysis

Precedents Cited

The judgment heavily referenced several key precedents and directives that underpin environmental and planning law within the EU framework:

• Case C-275/09 Brussels Hoofdstedeliljk Gewest: This case addressed the obligations under the EIA Directive when previous stages in a multi-stage consent process lacked a proper EIA.
• Kelly v. An Bord Pleanála [2014] IEHC 400: Clarified the legal test for "screening out" in appropriate assessments under the Habitats Directive.
• Case C-43/10 Nomarchiaki Aftodioikisi Aitoloakarnanias: Emphasized that the WFD imposes binding obligations on Member States to prevent deterioration and achieve good status of water bodies.
• Weser Case: Reinforced that projects causing deterioration or jeopardizing the attainment of good water status must be refused authorization under the WFD.

Legal Reasoning

The High Court's legal reasoning unfolded through a meticulous analysis of both national regulations and EU directives:

• Consent under PDR 2001: The court found that the Board had obtained the necessary consents from landowners directly impacted by the pipeline's physical infrastructure. The applicant failed to prove that the abstraction would significantly affect land under other proprietors.
• Appropriate Assessment for Connemara Bog SAC: The court upheld the Board's decision to screen out the Connemara Bog SAC, given the substantial distance (over 10 km) and lack of direct hydrological connection, rendering the SAC unlikely to be significantly affected by the development.
• Environmental Impact Assessment (EIA): The applicant’s innovative but procedurally flawed argument to compel an EIA for connected developments was dismissed. The court emphasized that the lack of EIA for separate developments does not automatically necessitate a combined EIA unless they form a multi-stage consent process.
• Water Framework Directive (WFD) Compliance: The crux of the judgment lies in the Board’s failure to comply with the WFD. The EPA had not assigned a status to Loch an Mhuilinn, which is a mandatory prerequisite for assessing the environmental implications of any development affecting the water body. Without this status, the Board could not ascertain whether the abstraction would lead to deterioration or impede achieving good surface water status.

Impact

This judgment underscores the critical importance of adhering to the WFD's procedural requirements. It establishes that:

• The determination of a water body's status by the designated authority (EPA) is fundamental before any developmental permissions can be granted.
• Planning authorities cannot rely on proxy evaluations or internal assessments that do not align with the WFD's prescribed methodologies.
• Non-compliance with EU environmental directives, particularly in multi-jurisdictional contexts, can nullify previously granted permissions.

Future cases involving water abstraction and environmental impact will reference this judgment to ensure that all procedural mandates under the WFD are meticulously followed. This decision serves as a caution to planning authorities to coordinate effectively with environmental agencies and adhere strictly to established environmental assessment protocols.

Complex Concepts Simplified

Understanding these concepts is essential for comprehending the legal intricacies involved in environmental planning and the enforcement of directives like the WFD and the Habitats Directive.

Conclusion

The judgment in Sweetman v. An Bord Pleanála & Anor serves as a pivotal reference point in Irish environmental law, particularly concerning the implementation of the EU's Water Framework Directive. It highlights the non-negotiable nature of procedural compliance in environmental assessments and planning permissions. The High Court's decision reinforces the necessity for environmental authorities to exhaustively follow established directives and collaborate seamlessly to safeguard environmental integrity.

For stakeholders in environmental planning and development, this case emphasizes the importance of ensuring that all regulatory prerequisites, especially those related to environmental assessments, are meticulously satisfied. It also serves as a reminder of the judiciary's role in upholding environmental standards and the imperatives of legislative compliance within the EU framework.
