Minister for Justice Helen McEntee has denied that she misled the Dáil over legislation that introduced changes in relation to the admissibility of documents in court cases.
The Civil Law and Criminal Law Provisions Bill was passed before the summer recess.
Ms McEntee denied she had been lobbied by vulture funds in relation to the changes.
The minister sought a waiver for prelegislative scrutiny for the legislation.
She said there were changes made when the legislation was finally published.
Ms McEntee was criticised by Sinn Féin, which said the Dáil had not been informed that the changes would be included in the final legislation.
"There was absolutely no attempt to mislead anyone in the Dáil," she said.
Ms McEntee said that stakeholders had been consulted about the legislation and it had been sought for some time.
She said the aim of the bill was to make the legal system more efficient and in the majority of cases people may wish to provide business records without each document being witnessed.
"There was a suggestion at the time that I had been lobbied by vulture funds but I can categorically say nobody contacted me or my Department," she said.
However, Sinn Féin's Martin Kenny said no speaker from Government or opposition was in favour of the provision that was finally included.
"Everybody said it should be deferred. Everybody that I spoke to in the legal profession said there was no urgency," Mr Kenny said.
He said whoever "slipped in" the provision should be held accountable and should be "sacked".
