The controversy around the attempted appointment of Dr Tony Holohan to Trinity College Dublin raises questions over how the Department of Health is run.
That's according to the head of the Oireachtas Committee on Finance, John McGuinness.
It comes as senior civil servants - including Martin Fraser and Robert Watt - are set to be called before the committee.
Mr McGuinness told Newstalk Breakfast they hope to speak to all those involved.
"Before the 21st of this month we hope to compile the necessary reports and paperwork from each department, leading up to the decision regarding Tony Holohan.
"The hearing then will be on the 27th of April.
"The report, which has been issued to the Taoiseach, has been sought - members have sought other information from different departments.
"And we hope to then have the witnesses before the committee - the secretaries-general of each department - to discuss how all of this mess happened".
Asked if this raises questions about how the Department of Health is run, he says: "It does indeed, it would seem that there's a loose management system there to say the least.
"But that needs to be investigated; what we have at the moment is just leaks from various sources relative to the document that was produced by Mr Watt.
"But there are many others that would have knowledge of what was going on in relation to this appointment, and we need to hear from them also.
"And we need to interrogate the report itself as to the detail that's provided in it, and provide clarity for the public".
'Independent report'
Mr McGuinness denies they are out to get anyone, but just want to establish the facts.
"We're not gunning for anyone... we want to establish the facts around this.
"I think that the report that was asked for by the Taoiseach from the Department of Health, that should have been an independent report.
"And that might have brought more clarity to what happened prior to this becoming a very public controversy".
And he believes the appointment of Dr Holohan was too high profile to go without higher approval.
"This was a very high profile individual with a salary attached - at €187,000 - it was not insignificant.
"It should have been brought to the attention of the Minister, it should have been discussed by the high-level management group within the department.
"We don't know whether any of that happened or not - we do know that the [Health] Minister was not informed, and I find that quite peculiar in terms of the management of any department."
