The former master of the National Maternity Hospital says he won't quit following the row over the new facility.
Dr Peter Boylan, who sits on the board of Holles Street, doubts the hospital will be truly independent from the Sisters of Charity.
The new facility is to be built on the campus of St. Vincent's Hospital which the nuns already own.
Under a deal brokered by the former head of the Workplace Relations Commission, it's understood the Sisters of Charity will be given ownership of the maternity hospital but medics will maintain independence in how it's run.
However Dr Boylan has raised concerns that that may not happen in practise, as many treatments in the area of women's health (like medical terminations or IVF) go against the teachings of the church.
Dr Boylan has cited an interview in last weekend's Sunday Times with the Bishop of Elphin:
"Bishop Doran was crystal clear that any property owned by the church is ecclesiastical property and canon law takes precedence over state law in those institutions and the ultimate person with governance oversight is the pope."
Dr Boylan has revealed that he was asked by text message to resign his position for showing 'disloyalty' to the board in relation to the hospital deal, which is still not set in stone. However he is refusing:
"I don't think I should resign. I didn't cause this problem, I just got involved in it. I feel a responsibility to speak because this is an issue that affects the health of women in Ireland going forward and I can't in all honesty stay silent about this."
