It is expected the Vatican will give its formal response to the Cloyne report early next week.
It is reported that a 15-page report had been finished by Vatican officials and its release is "imminent".
The Cloyne Report found how the diocese failed to report nine out of 15 complaints made against priests between 1996 and 2005 when child protection procedures were already in place.
It also revealed how the former Bishop John Magee misled a previous inquiry and gave a false account of how he was handling allegations.
