High Court Establishes Rigorous Standards for Interlocutory Injunctions on Migration Projects

Introduction

The case of Croghan & Ors v Collins & Ors (Approved) ([2024] IEHC 607) was adjudicated by the High Court of Ireland on October 31, 2024. The plaintiffs, acting as litigants in person, sought interlocutory injunctions to prevent the housing of migrants at the Coolock Crown Paints site in Dublin. This case revolves around significant legal questions concerning the application of EU principles within domestic law and sets a precedent regarding the standards required for obtaining such injunctions.

Summary of the Judgment

Justice David Holland delivered the judgment, rejecting the plaintiffs' application for interlocutory injunctions. The plaintiffs based their claims on the precautionary principle under EU environmental law (Article 191 TFEU) and obligations under the Aarhus Convention related to public participation. However, the High Court found these legal bases unstateable within Irish law, as they lack direct effect domestically. Furthermore, the court criticized the plaintiffs' pleadings for lacking substantiated evidence and for containing inflammatory and discriminatory remarks against migrants.

Analysis

Precedents Cited

The judgment referenced several key precedents:

Merck Sharp & Dohme Corporation v Clonmel Healthcare Limited [2019] IESC 65: Outlined principles for granting interlocutory injunctions.
Kelly v An Bord Pleanála & National Transport Agency [2024] IEHC 364: Discussed court latitude in assisting lay litigants.
Dromaprop Ltd v Leitrim County Council [2024] IEHC 233: Clarified the strict construction of planning exemption classes.
Jennings v An Bord Pleanála [2022] IEHC 249: Addressed the role of international conventions in domestic law.
Okunade v Minister for Justice, Equality and Law Reform [2012] 3 IR 152: Emphasized judicial restraint in issuing mandamus.

These cases collectively influenced the court’s approach in assessing the stateability of the plaintiffs' claims and the appropriate application of legal principles.

Legal Reasoning

The court’s legal reasoning centered on the necessity for claims to have a direct basis in domestic law. While the precautionary principle and the Aarhus Convention are foundational in EU and international law, respectively, their application within Irish legal proceedings requires explicit incorporation into domestic statutes. The plaintiffs failed to demonstrate how these principles translate into enforceable rights under Irish law, rendering their claims unstateable.

Additionally, the court scrutinized the plaintiffs' narratives, highlighting a lack of substantial evidence to support allegations of racism, genocide, and other severe claims. The court emphasized that accusations in legal pleadings must be supported by credible evidence rather than inflammatory rhetoric.

Impact

This judgment underscores the High Court’s stringent requirements for interlocutory injunctions, especially when grounded in international or EU principles not directly embedded in domestic law. Future cases involving similar claims will need to establish clear stateable grounds within Irish legislation to succeed in obtaining injunctions. Moreover, the court's rejection of unsupported and discriminatory allegations reinforces the imperative for plaintiffs to present evidence-based claims.

Conclusion

The High Court of Ireland, in Croghan & Ors v Collins & Ors (Approved) [2024] IEHC 607, firmly established that interlocutory injunctions must be founded on stateable and evidence-backed legal grounds within domestic law. The court dismissed the plaintiffs' reliance on the precautionary principle and the Aarhus Convention, highlighting the necessity for direct applicability of such principles in Irish law. This judgment serves as a critical reminder for litigants to anchor their claims in the national legal framework and ensures that courts maintain their role as impartial arbiters based on substantiated evidence.

The decision also highlights the court’s vigilance against discriminatory and unfounded allegations, promoting a judicial environment where legal proceedings are conducted with rigor and respect for evidence-based claims. As migration and related legal challenges continue to be significant societal issues, this precedent will guide future litigants and courts in navigating the complexities of applying international principles within the domestic legal context.
