The inquiry into the sale of SiteServ has asked a company owned by Denis O'Brien to waive its right of confidentiality on up to 50,000 pages of documents.
The Cregan Commission has found that while SiteServ itself has waived confidentiality over some of its banking arrangements with IBRC, its subsidiaries have not.
SiteServ PLC was wound down after its subsidiaries and other assets were sold to Denis O'Brien's Millington firm, based in the Isle of Man, in a deal that saw IBRC write off corporate debts of over €100 million.
The transaction gained prominence after one of its subsidiaries, GMC Sierra, later won a lucrative contract to install hundreds of thousands of water meters on behalf of Irish Water.
SiteServ PLC has since been reconstituted and has agreed to waive its bank-client confidentiality over some documents - but says it is not in a position to do so on behalf of its former subsidiaries.
As a result, the Commission has written to Millington, which has now been asked to waive its right of confidentiality on those documents.
50,000 pages of documents could require waiver
Millington's solicitors Arthur Cox replied "seeking a list of the documents over which a waiver of confidentiality is being sought".
However the Commission says this process has been delayed because IBRC's liquidators are still gathering documents which must be included on the list of those being sent to Millington.
In an interim report sent to Enda Kenny earlier this month, Justice Brian Cregan said there are over 50,000 pages of documents which were needed before the final list could be sent to Millington.
The interim report - the second published by Cregan's commission - was published by the Department of the Taoiseach last night.
Enda Kenny has extended the Commission's deadline until the end of June, but given that certain other legal roadblocks remain - which have been addressed for several months, due to the general election and subsequent political vacuum - further extensions are likely to be required.
