The Women of Honour Group has said it is disappointed that the Government has moved to design draft terms of reference for a statutory inquiry before consulting the group or other victims.
It comes after the group met Tánaiste and Minister for Defence Micheál Martin.
He also held meeting with the Defence Women's Network, the Representative Associations (RACO, PDFORRA, RDFRA), the Men and Women of Honour group, the Veteran Associations and with Civil and Civilian Employee Unions.
The Tánaiste shared draft Terms of Reference for the forthcoming inquiry during these meetings.
"We remain with a feeling that the Government seeks to railroad through us and others without any courtesy or respect. It smells of the same institutional abuse as victims endured in the Defence Forces.
"Meetings should have been held to agree a process on terms of reference. Nothing less than a full Public Tribunal to ascertain the truth will work. The people of Ireland deserve the truth," The Women of Honour Group said in a statement following the meeting.
While a statement issued by the Department of Defence said the Tánaiste reiterated the Government's commitment to set up the statutory inquiry that was recommended by the Independent Review Group.
It added that all groups have been given the opportunity to provide feedback to the Tánaiste on the draft Terms of Reference.
