Lawyers representing the airlines informed Ms. Justice Niamh Hyland that, following a similar application by the airport’s operator, DAA, earlier this week, they also intend to pursue judicial review proceedings.

The daa was granted permission on May 7th to challenge the IAA’s decision, which, according to DAA, would exceed the airport’s annual passenger cap of 32 million.

The IAA’s decision pertains to the ‘Winter 2024 Coordination Parameters’ set by the authority.

DAA argues that these parameters violate the planning permissions that limit the airport’s capacity to 32 million passengers per year and potentially breach EU regulations.

DAA is seeking to have the winter parameters quashed or, alternatively, to have the May 7th decision reopened, temporary parameters set, or other measures implemented to prevent breaching the planning permissions.

On Thursday, Ms. Justice Hyland informed counsel for Aer Lingus and Ryanair that she would consider their applications for leave to bring similar challenges next week.

The airlines are requesting that their cases be scheduled for a case management date already allocated for the DAA case at the end of the month.
