Dublin city councillors have called for a public hearing into licences for Garth Brooks concerts at Croke Park.
Tickets have been sold for five Garth Brooks concerts in Croke Park this July.
The motion calling for oral submissions to be heard before Dublin City Council planners make a decision on whether the concerts go ahead was proposed by independent councillor Nial Ring.
Councillors agreed the motion with many accusing the Croke Park authorities of breaking an agreement with residents to limit the concerts to three a year.
Many questioned how a promoter could sell €26m worth of tickets before permission is granted.
Fianna Fáil councillor Paul Mc Auliffe said incidents at the Phoenix Park should have been a watershed.
Assistant Manager Philip Maguire said a licence application is due in mid May followed by a five-week public consultation period before the statutory bodies would hold a statutory meeting to consider an event plan.
There will then be an opportunity for a request for further information or oral hearing at that stage.
Mr Maguire said it would not be appropriate to give a commitment for a hearing now but he would "bear in mind" what councillors had said.
He said it was normal for promoters to sell tickets with licences pending.
