The Department of Justice has been in the firing line for months, but worse may be to come for the civil servants, writes Cormac O’Keeffe

The Department of Justice is closed and secretive and requires "fundamental and sustained organisational and cultural change", a high-level report has concluded.

Department of Justice secretary general Brian Purcell is refusing to answer questions about the recent controversial resignation of the Garda commissioner as his future as department chief hangs in the air.

Taoiseach Enda Kenny has said that he has "no problem apologising" to whistleblower Sgt Maurice McCabe for the way the Government handled his warnings of garda malpractice.

Newly appointed Justice Minister Frances Fitzgerald is unlikely to go looking for a scalp in the Garda force or the Department of Justice any time soon, judging by her first few days and actions in government.

Concerns have been raised about the quality of training at Templemore during the Celtic Tiger years, says Cormac O’Keeffe.

The Taoiseach Enda Kenny has apologised to Sergeant Maurice McCabe for the state's failure to investigate his allegations more quickly.

Transport Minister Leo Varadkar has warned that a culture of change is needed in An Garda Síochána as the Cabinet begins talks this week about setting up a full inquiry into allegations of misconduct.

Ireland is very good at producing reports but hopeless about taking action. Regrettably, the reality is that official probes by or into agencies of the State usually end up gathering dust on ministerial shelves.

The Taoiseach has handed the new Minister for Justice a fresh batch of allegations of Garda misconduct.

Sinn Féin has said the new Justice Minister needs to ensure that Garda whistleblowers are protected.

The lowest point may well have been the death threat from another member of the force.

Sergeant Maurice McCabe made complaints about 16 individual incidents relating to failures by gardaí to investigate reported crimes, internal matters including harassment of officers, and allegations of misconduct by individual members of the force. Caroline O’Doherty and Cormac O’Keeffe report on Seán Guerin’s examination of the matters

It is an ironic twist of this political saga that the man who was hailed as the most reforming minister of all time was brought down by behaviour that belongs to a different era.

The word of the Garda commissioner was "accepted without question" by Alan Shatter, the former justice minister, when he examined complaints of misconduct against him in January 2012.

No independent probe or assessment of whistleblower Sgt Maurice McCabe’s complaints about gardaí was ordered by Department of Justice officials, the Guerin report has concluded.

The report by Seán Guerin report documents information which "supports" allegations by whistleblower Sergeant Maurice McCabe of "significant deficiencies" in Garda investigations in Bailieborough.

The wife of Garda whistleblower Maurice McCabe said she got no help from Alan Shatter when she wrote to him about a death threat against her family.

There is a theme running through the narrative of the Guerin report like a thread. Time and again, the same issues arise: A criminal investigation is not conducted properly. Sergeant Maurice McCabe complains about it in a detailed manner. The complaint is investigated by senior officers, more often than not concluding there is little to see here.

The required reading list for the new batch of garda recruits — the first trainees in five years — might be getting a late edition.

It is hard to conceive of a more damning indictment of former justice minister Alan Shatter, the dysfunctional Department of Justice, or of the Garda Siochána, than barrister Seán Guerin’s scathing report on their cavalier handling of, and failure to properly investigate, allegations of wrongdoing brought to light by whistleblower Sergeant Maurice McCabe.

Frances Fitzgerald, the new Minister for Justice, has announced that there will be a commission on investigation as recommended by the Guerin report.
