A new report is expected to lay bare the extent of responsibility that successive Irish governments must accept for what went on in Magdalene laundries.
An 18-month investigation into the Catholic-run workhouses will formally reveal state involvement and knowledge of the harrowing life women in the institutions endured between 1922 and 1996.
A committee chaired by Senator Martin McAleese, who has since resigned from politics, spent 18 months establishing the role official Ireland played in the for-profit Church-run operation. Survivors have been campaigning for the last 10 years for an apology from state and Church and a transparent compensation scheme.
Over the 74 years, thousands of single mothers and other women were put to work in detention, mostly in industrial for-profit laundries run by nuns from four religious congregations. Each woman had her Christian name changed, her surname unused and most have since died.
James Smith, associate professor at Boston College and member of the Justice for Magdalenes (JFM) advisory board, said: "I hope the Government listen. The women can no longer be held hostage to a political system. Time is of the essence, it is the one commodity many of these women can ill afford."
Survivors have called for a transparent and non-adversarial compensation process for all to be set up, with pensions, lost wages, health and housing services and redress all accounted for.
Mr Smith said: "Until there is an apology - I have met so many women who will not come forward, and have no intention of engaging in any process - they might still not come forward, but other women might come forward if they get an assurance that they were wronged."
Religious orders the Sisters of Our Lady of Charity ran laundries at Drumcondra and Sean MacDermott Street in Dublin, the Sisters of Mercy in Galway and Dun Laoghaire, the Religious Sisters of Charity in Donnybrook, Dublin, and Cork, and the Sisters of the Good Shepherd in Limerick, Cork, Waterford and New Ross.
JFM is aware of at least 988 women who are buried in laundry plots in cemeteries across Ireland and therefore must have stayed for life. Mass graves have been identified in Mount St Lawrence Cemetery in Limerick, Glasnevin in Dublin, Sunday's Well in Cork and at sites in Galway.
The inquiry into the Magdalene scandal was finally prompted by a report from the United Nations Committee Against Torture in June 2011. It called for prosecutions where necessary and compensation to surviving women.
