The Public Accounts Committee has been told it does not have the legal right to investigate allegations of tax evasion.
The committee has been meeting behind closed doors to take legal advice on the dossier it received last week.
TDs have been told that the documents they received are not protected by whistle-blower laws – and that they cannot interview the whistle-blower himself.
It is understood that the Dáil would need to pass a formal resolution in order to give the PAC the power to investigate.
In the meantime, TDs have asked the public spending watchdog to update them on the collection of taxes due from the holders of accounts at Ansbacher bank.

Anyone who is willing to allow these political self-serving parasites continue in power is equally guilty of this appalling fraud on the Irish nation! We owe it to our children and the next generation to make a stand against totally corrupt system now! We must now make it clear that the next government must bring prosecutions against these tax evaders and every one of these parasites must have their state pensions withdrawn and all of their personal assets taken away as they have accumulated this wealth through criminal actions! This is unbelievable ,how much more are we going to take for God sake???
