As talks continue to try and come up with the solution to the Garth Brooks controversy, the Chief Executive of the Labour Relations Commission says time is of the essence to hammer out a deal, but a solution is still possible.

Kieran Mulvey claims Ireland's international reputation is becoming more damaged - the longer this saga wages on.

Mulvey - who acted as a mediator between residents and Croke Park officials to try to resolve the row over the number of concerts being held - says Dublin City Council's decision cannot be amended or appealed, but wonders if “a new process...within the existing constraints” might be possible.

“Is there a new process that can be put in place within the existing constraints that would allow this matter to be revisited afresh? I think they’re issues that are trying to be worked on at the moment,” Mulvey said.

Dublin City Council has decided to allow only three of the five concerts in Croke Park to take place. But Mr. Brooks says he'll perform five or none at all. Mulvey said he believes time is of the essence and any decision must be made soon.

“In the meantime Garth Brooks is awaiting decisions and I think we have a very short period of time to convince him to change his mind and come to Ireland,” Mulvey said.
