The Survivors of Symphysiotomy group has said that a redress scheme to be announced shortly by the Government is fundamentally flawed.
Speaking on RTÉ's Morning Ireland, Chairperson of the group Marie O'Connor said survivors had serious concerns about the proposed scheme.
She said: "First of all there's no admission of wrongdoing, secondly there's the issue of legal rights - survivors will be required to sign away their legal and Constitutional rights as a condition of entry to the scheme, before they know the outcome of a process controlled by the State, in other words before they know what money they will be offered."
Ms O'Connor said they were also concerned about the operation of the scheme itself.
She said: "It will be done by State assessors and State-appointed doctors, run by the State claims agency and we see a conflict of interest here because the State claims agency has a remit to save the State money and this is in completely in conflict with the best interests of survivors."
She also said that, contrary to what was recommended by the United Nations Human Rights Committee, there would be no individualised assessment.
Ms O'Connor said this meant the scheme was simply a box-ticking, paper exercise that will make no distinction between women who were badly injured and those who were not.
The Department of Health said a comprehensive response to the "long-standing and sensitive issue" was announced by the Government in July - including the establishment of an ex-gratia payment scheme and a commitment to the continued provision of medical cards for the women involved.
A spokesperson said Minister Leo Varadkar examined all aspects of the issue over the summer recess and "looks forward to meeting all three groups as soon as details of the scheme are finalised in the coming weeks".
The spokesperson said: "This issue has been going on for a very long time and this is the first Government to seek a resolution for the women concerned.
"There are three groups who represent the women affected by symphysiotomy, two of which have accepted in principle the proposals outlined in the ex-gratia scheme."
