Ms Nóirín O'Sullivan:

Absolutely. We may be talking about two separate things so I will clarify my position. This letter was received on 24 October 2015. It was quite evident from reading the content of the letter that there was, when I called it "an interpersonal dispute", a difference of opinion in the way that Mr. Barrett was handling things and Mr. Culhane's perception of that and vice versa. It involved a number of other parties. To my mind, what it highlighted was the interpersonal differences between two individuals operating in the same line of management and, most importantly, who had key roles to play in actually fixing the issues at hand. To come to Mr. Barrett, quite rightly he did what was proper and appropriate in bringing the matters to the attention of his then line manager, Mr. Dunne. That was back when he did do that. Then, Mr. Dunne was dealing with these matters and this letter comes into play. It was evident to me at that stage that here were two key people who actually had key roles to play in fixing these issues, which we had committed to doing. My focus was on making sure that those issues were dealt with and that any differences between these two individuals were resolved.
