Frank McBrearty senior has rejected an appeal by the Minister for Justice for his family to return to the Morris Tribunal.
The family withdrew from the Tribunal in April, in protest at the fact that the state would not guarantee their legal costs would be covered.
Speaking on RTÉ's This Week programme, Mr McDowell said the families' legal teams would be paid promptly but only in arrears.
However, Mr McBrearty said his legal costs amount to ¤1 million and his lawyers will have to wait a considerable amount of time before they are paid, as their costs have to come before the taxing master in the High Court.
The minister also said he would not resign in light of the tribunal's findings of corruption and negligence among some gardaí in Donegal.
Frank Mc Brearty Senior has responded to the Minister's remarks by asking him to take part in a public debate on the Morris tribunal.
