The Taoiseach has said he would consider a proposal by the Fine Gael leader for measures to deal with the overpricing of tickets for sporting and musical events.
Mr Ahern said if an old law existed, it probably involved a low fine which was not a deterrent.
"The issue of trying to stop people selling tickets on would not be easily enforced, no matter how it is done," he added.
"As Deputy Enda Kenny wants me to consider the issue, I will raise it and see what happens."
Conceding that there was an issue involved, Mr Ahern said U2 and rugby tickets were like gold dust.
"The reason I wanted to build a national stadium was so that people fit in and we would not have a problem," he added.
Mr Kenny said the Government could introduce legislation which would in some way res-trict, limit or put out of business the touts who were charging exorbitant fees and ripping off genuine fans of sport and music.
He had noticed that two tickets for a U2 concert, normally costing between €60 and €80, were on sale for €500 within minutes of the tickets going on sale. He had read of two terrace tickets for the Ireland-England rugby match in Lansdowne Road attracting a bid of €1,350.
"This is disgraceful," said Mr Kenny. "The only people who profit from this practice are the ticket touts. In France and Britain, there is very strong anti-tout legislation."
He understood that ticket touts were operating at the Point on the previous night. A TD had told him he paid €500 for two tickets for a Pavarotti concert.
