Figures show third parties and witnesses have so far claimed some €11.1 million for co-operating with the corruption inquiry. Of these, Judge Mahon has agreed to settle €8.49m in costs.
Several other claims amounting to more than €800,000 remain unresolved with legal accountants.
However, the mounting costs for witnesses and their legal teams only relate to the inquiry’s first few years.
According to the Department of Environment, third-party costs are only being considered for hearings between 1997 and 2002.
“It is understood the chairman proposes to rule on costs applications relating to the period for 2003-2008 once the tribunal’s final report is completed — probably in 2009,” stated the department.
A full breakdown of payments to third parties for the first five years of the tribunal shows costs paid to 35 individuals, as well as 22 corporate claims settled.
