An environmental group's challenge over how the €500m Shannon liquefied natural gas (LNG) terminal and pipeline was included in a list of EU Projects of Community Importance has implications not just for Ireland "but potentially across the EU", the State has told the High Court.
Suzanne Kingston BL, for various State defendants, said the European Commission has been informed of the proceedings, which include a challenge to the validity of Commission decisions, but so far no response has been received from it.
Mr Justice Denis McDonald, who earlier this month granted leave to Friends of the Irish Environment (FIE) to bring the case, said he wants it to progress speedily.
The case centres on the decision-making process that lead to inclusion of the project in a list that entitles it to the "most rapid treatment legally possible".
The proposed development is for four liquefied natural gas tanks, jetties to receive ships of LNG and associated works near Tarbert, Co Kerry.
