All five Garth Brooks concerts planned to take place in Croke Park at the end of the month have been cancelled.
Aiken Promotions have said they have exhausted all avenues regarding the staging of the event.
The ticket return process will be outlined tomorrow.
An application to prevent three licensed Garth Brooks concerts from going ahead later this month was expected to be heard by the High Court on Thursday.
Local resident Brian Duff had brought an application against Aiken Promotions and Croke Park seeking an injunction to prevent the shows on 25, 26 and 27 July from taking place.
Mr Justice Paul Gilligan granted permission to lawyers for Mr Duff to bring the injunction application on Thursday morning.
