The Pope accepted the resignation of another Irish bishop implicated in the catastrophe:
"[The Pope] Accepted the resignation from the pastoral care of the dioceses of Kildare and Leighlin, Ireland, presented by Bishop James Moriarty, in accordance with canon 401 para. 2 of the Code of Canon Law."

The expectation is that the Pope will be accepting more such resignations in the not too distant future.
