The start of the Cervical Check tribunal has been delayed by a number of days.
Hearings had been due to start today, but concerns had been flagged by a number of advocates, including Kilkenny woman Vicky Phelan.
They raised issues about the adversarial nature of hearings, the statute of limitations and the possibility returning to the tribunal at a later date.
In a statement, the Department of Health said there is ongoing engagement between the 221 plus group and Minister Stephen Donnelly, and the start date has been paused for a number of days.
