RTÉ has learned that the Director of Public Prosecutions will not oppose an application by former nun Nora Wall that there was a miscarriage of justice in her case.
In 1999 Ms Wall had her conviction for rape quashed and the DPP fully and ungrudgingly accepted that she was entitled to be presumed innocent of all charges.
The Court of Criminal Appeal was due to consider an application for the certificate in a hearing next week.
