The judgment extensively references established jurisprudence to inform its decision, particularly focusing on the principles set forth in Veolia Water UK plc v Fingal County Council (No. 2) [2007] 2 IR 81 and Chubb European Group SE v The Health Insurance Authority [2020] IECA 183.

• Veolia Water UK plc v Fingal County Council (No. 2) [2007] 2 IR 81: This seminal case established that costs typically follow the event, but emphasized the court's discretion in situations involving multiple issues or partial successes. It highlighted the need to identify the 'event' and allocate costs accordingly, especially in complex litigations.
• Chubb European Group SE v The Health Insurance Authority [2020] IECA 183: Reinforced the Veolia principles, particularly regarding the circumstances under which costs may not entirely follow the event. It underscored that the mere raising of unmeritorious points does not automatically warrant a full costs order against the winning party.
• MD v ND [2015] IESC 66: Clarified that partial success does not preclude a costs award, provided the unsuccessful points were not unmeritorious and did not disproportionately increase litigation costs.
• Connelly v An Bord Pleanála [2018] IESC 36: Emphasized a broad, pragmatic approach to costs, cautioning against meticulous parsing of issues that could lead to unnecessarily prolonged and costly proceedings.

Legal Reasoning

Justice Dignam's legal reasoning navigated the complexities of cost allocation in mixed outcomes. The court recognized that while the defendants did not achieve complete success, their efforts in dismissing significant portions of the plaintiffs' claims justified a partial costs award. The decision hinged on several key principles:

• Identification of the Event: The court determined that the defendants secured a substantive entitlement by successfully challenging claims that were repetitions of previous litigation, thereby constituting an abuse of process.
• Partial Success and Proportionality: Acknowledging that the defendants were not entirely successful, the court considered the proportionality of costs based on the material success achieved versus the unsuccessful but reasonable points raised.
• Discretion Under Statute: Drawing on sections 168 and 169 of the Legal Services Regulation Act 2015, the court exercised discretion to award costs in a balanced manner, reflecting both parties' levels of success and the conduct during litigation.
• Overlap of Issues: The presence of overlapping issues complicated a precise cost allocation. The court deemed it impractical to segregate costs attributable to specific points, leading to a more holistic assessment.

Ultimately, the court opted for a 50% costs award to the defendants, recognizing their substantive achievements while acknowledging the plaintiffs' partial successes.

Impact

This judgment offers several implications for future litigation, particularly in cases of partial success:

• Refinement of Cost Allocation Principles: The decision reinforces the principle that cost awards must reflect the nuanced outcomes of cases, moving away from a binary win-lose framework.
• Encouragement of Reasonable Litigation Practices: By distinguishing between unmeritorious and reasonable points, the court encourages parties to litigate responsibly without fear of disproportionate cost penalties for raising legitimate arguments.
• Guidance for Courts: Provides a pragmatic approach for judges in assessing costs, especially in complex cases with multiple overlapping issues.
• Precedential Value: Bolsters the jurisprudential landscape regarding cost awards, aligning with and expanding upon prior rulings like Veolia and Chubb.

Legal practitioners will find this judgment instrumental in strategizing litigation and anticipating potential costs outcomes in cases where success is not absolute.

Abuse of Process

Definition: Abuse of process refers to the misuse of legal proceedings for a purpose other than resolving the legitimate dispute. This can include re-litigating matters that have already been decided or are unfounded.

Application in Case: The defendants successfully argued that the plaintiffs' claims on certain grounds were repetitive of issues already addressed in previous litigation, thus constituting an abuse of process.

Res Judicata

Definition: Res judicata is a legal principle that prevents the same parties from litigating the same issue more than once once it has been judicially resolved.

Application in Case: One of the defendants contended that the plaintiffs were trying to re-litigate matters previously adjudicated, thereby invoking res judicata to seek dismissal of the current proceedings.

Costs Follow the Event

Definition: This doctrine posits that the losing party in litigation should bear the costs incurred by the winning party.

Application in Case: While traditionally costs follow the event, the court exercised discretion to allocate costs proportionately due to the partial success of both parties.

Legal Services Regulation Act 2015

Relevance: This Act governs the rules surrounding the awarding of costs in civil proceedings in Ireland. Key sections include:

• Section 168: Allows courts to order one party to pay all or part of another party's costs.
• Section 169: Establishes that the entirely successful party is generally entitled to costs, but provides criteria for discretion in awarding costs.
