The European Court of Human Rights has declared applications from three Irish women who underwent symphysiotomies in Irish maternity hospitals in the 1960s as inadmissible.

Each of the three applications - identified as LF, KO'S and WM - underwent the procedures either during or in advance of labour in three different maternity hospitals.

A symphysiotomy is a surgical procedure on the pelvis to facilitate child birth.

All three women had alleged that they had not been informed about the procedure and had not given their full and informed consent.

They also alleged that they suffered physical and psychological trauma as a result of the procedure.

In their application to the ECHR, the women complained that the use of the procedure in Ireland had not been the subject of a Convention-compliant domestic investigation.

They also complained that they had been unable to fully litigate their claims at the domestic level.

One applicant also complained that in allowing symphysiotomies to take place, the State had failed in its obligation to protect women from inhuman and degrading treatment.

The ECHR has found that in one case the complaint was inadmissible as the applicant had failed to exhaust domestic remedies in the Irish courts.

In the other two cases, it found the applicants' complaints to be manifestly ill-founded, indicating that a question regarding the exhaustion of domestic remedies also arose.

The court has said that the decisions are final.

While symphysiotomies fell out of favour in western Europe due to safer Caesarean sections, around 1,500 women underwent the procedure in Ireland between the 1940s and 1980s.

In 2014, the Government agreed a redress scheme for women who underwent the procedure. The redress ranges from €50,000 to €150,000.
