Dublin Croke Park residents are preparing to seek a High Court injunction if licences are granted for the Garth Brooks concerts.
At a heated meeting between the GAA, Aiken Promotions and Croke Park residents, it emerged that a written agreement in 2009, where no more than three concerts a year were to be held at the national stadium, was to be ignored.
Peter McKenna, stadium director, told the crowded room that "times move on".
Eamon O'Brien, chairman of the Croke Park Streets Committee, said: "There was uproar when he said it."
Patrick Gates, a member of the residents' association, described the meeting as the "biggest he'd ever seen" and that people were "irate and angry" but very measured in their response to concert promoters and the GAA.
A total of nine major events are to take place in Croke Park this year and tickets to the five Garth Brooks concerts were sold subject to licence.
Promoters have 10 weeks to apply for a licence before the first scheduled gig and the residents will then have five weeks to protest against the concerts.
"We are looking at all our options, which include protests and an injunction," Mr Gates told the Irish Independent.
Mr O'Brien said in 30 years Croke Park has only been refused one application by Dublin City Council.
"People are really, really angry and irate," stated Mr Gates.
"We feel they have contempt for the residents and that Croke Park has broken agreement after agreement with the residents," said Mr Gates.
"The level of anger, frustration and disgust with Croke Park/GAA at the way they went about announcing the Garth Brooks concerts was palpable," stated independent councillor Nial Ring.
There is a complete lack of trust in the GAA, and the lack of communication, consultation and respect has left the GAA in a position where the local residents will do all in their power to stop the concerts," stated the councillor.
The residents are planning another meeting, to take place in the coming days.
