The Murphy Report (November 2009) mentions Bishop Drennan's name in connection with only one case. In that case suspicions and concerns (not allegations of child sexual abuse) about a certain Fr Guido were brought to Bishop Drennan's attention as a time when the latter was an Auxialiary Bishop of Dublin.
The Murphy Report concludes about that particular case: "The archdiocese acted correctly in immediately addressing the concerns and suspicions in this case. It did everything possible to assist Fr Guido to address the issues of concern and, when it was clear that a limited ministry was not possible, it helped him to get started on another career." (Murphy Report, p620)
Nevertheless there were demands in the media that Bishop Drennan resign. The current Archbishop of Dublin Diarmuid Martin was conspicuous by his lack of support for Bishop Drennan.
