The Oireachtas Finance Committee looks set to question a number of people in relation to the sale of Siteserv.
Former Anglo Irish Bank chairman Alan Dukes and businessman Denis O'Brien will be asked to appear before hearings.
Siteserv was sold to Mr O'Brien's Millington by the Irish Bank Resolution Corporation (IBRC) at a loss to the taxpayer of more than €100m.
The Committee passed a motion from People Before Profit TD Richard Boyd Barrett, who wanted the sale of Siteserv by IBRC examined.
"We need to hear from the major players from the Government and the Department of Finance, from IBRC itself and some of the big purchasers of IBRC assets, such as Denis O’Brien, to establish whether or not the public interest was properly served and protected, or not," said Deputy Boyd Barret.
"The easiest and most transparent way to, at least, begin the process of investigating the controversial and worrying issues that have emerged from the current IBRC and Siteserv controversy is to have the issues examined in an open and public way by the relevant Dáil committee.”
