The Government has promised to make a decision before the end of October on whether or not to hold a fresh inquiry into the 1981 Stardust disaster.
Forty-eight people lost their lives when fire engulfed the Stardust nightclub in the Artane area of Dublin on St Valentine's night 25 years ago.
A tribunal into the incident later blamed arson, exonerating the owners of legal responsibility, despite widespread evidence of safety failings.
Relatives of those killed in the blaze met the Taoiseach yesterday to discuss their campaign for a fresh inquiry.
They say they are angry and disappointed that the Government is postponing a decision on the matter until later in the year.
