I haven't studied them in depth tbh. The ones I see highlighted seem overly lenient but I don't know if he is always lenient or if it is just that the overly lenient sentences are the only ones that are reported.
A better way of getting a sense of whether or not his sentences are out of kilter would be to see what percentage of them get appealled by the DPP. I don't have an answer to that, but it would be interesting to see if his appeals list are markedly higher than the average.
When Judge Pattwell was in.North Cork, for example, because he was so over the top in his sentences his appeal lists clogged all the Circuit court lists.
