It is understood some corruption findings will remain against former minister Ray Burke when the Planning and Payments Tribunal amends its report next week.
A finding of corruption in relation to a payment from Joseph Murphy Structural Engineering is being withdrawn as it is based on the testimony of the late James Gogarty.
However, other findings of corruption in relation to payments of £75,000stg from builders Brennan and McGowan and auctioneer John Finnegan and £35,000 from former head of Century Radio Oliver Barry will remain.
Findings against a number of witnesses based on Mr Gogarty's evidence are being removed following a Supreme Court ruling that the tribunal had not fully disclosed his statements.
Former Dublin city and county manager George Redmond took a successful Supreme Court appeal arguing that corruption findings should be withdrawn.
Witnesses who the tribunal found had failed to cooperate with the inquiry had previously been told they are now entitled to have their legal costs paid by the state.
This follows another Supreme Court ruling that the tribunal was not entitled to make a finding of obstruction in this instances, as that amounted to a criminal offence.
The amended second interim report is expected to be placed on the tribunal's website early next week.
