On the use of the title “Mayor” or “Cathaoirleach”, under this legislation, with the exception of Dublin, Cork, Galway, Limerick and Waterford city councils, the chairs of local authorities will only be allowed to be called “Cathaoirleach”.

The situation in my own county is that we stuck with the "Cathaoirleach" title, which I firmly believe was the right thing to do.
