U2 could be hearing from the Dublin City Council over the decibel levels reached at their three concerts in Croke Park earlier this year.
A spokeswoman for the council confirmed that they are still deliberating over a decision about the noise levels reached during those three July dates.
"Dublin City Council has yet to issue a decision regarding the fine which will apply for noise breaches across the three events," she said.
U2 paid a €80,000 deposit for its Public Event License, and bar the noise infringement, the band was in compliance with all other stipulations.
Not that they could not afford the fine given their long and successful career, but, if they incur any penalty it will take them further in the red for the 360 tour.
Despite breaking attendance records and having a hugely popular jaunt around the globe to date, the band still have to break even on the tour and will not do so until it relaunches in spring 2010.
