A group representing survivors of the Magdalene laundries has presented a report to the Government alleging widespread state involvement with the notorious workhouses.
The Justice for Magdalenes (JFM) study accuses seven Government departments of being complicit in keeping the Catholic Church institutions running.
The body held a two-hour meeting with Justice Minister Alan Shatter and junior Health Minister Kathleen Lynch over the planned inquiry headed up by newly appointed Senator Martin McAleese.
Report author Professor James Smith of Boston College said survivors hope the details will help move the inquiry forward.
"By no means are we saying that it is comprehensive or complete, but it does document state interaction, what we might call complicity across seven government departments," he said.
Prof Smith met Mr Shatter and Ms Lynch as part of a delegation from JFM.
He said the 50-page report, supported by more than 400 pages of appendices, said they have evidence of complicity by the Departments of Justice, Education, Health, Local Government, Social Protection, Defence, jobs, enterprise and innovation and finance.
Senator McAleese was appointed by Mr Shatter to head up a committee to clarify any state interaction with the notorious workhouses. JFM spokeswoman Claire McGettrick said the meeting with Mr Shatter and Ms Lynch was the first step in the process.
"Nothing was decided, nothing was agreed upon. It was just laying the foundations," she said.
The four Catholic religious orders - the Sisters of Mercy, the Sisters of Our Lady of Charity, the Sisters of Charity, and the Good Shepherd Sisters - have agreed to co-operate with any inquiry.
