"[AZ's] behaviour can be described as extreme. It is rare, in my experience, to see such clear evidence of such serious sexual offending behaviour against such young victims. [AZ] is the father of the victims and was supposed to be caring for them at the time of the offences. As such, one element of this case is the inherent gross breach of trust. The extremely young ages of the victims make it difficult to predict the long-term consequences for them but it must be the case that [AZ] exposed them to the risk of serious psychological harm. It is quite possible that his actions could also have caused them serious physical harm, although, thankfully, this does not appear to have materialised. The fact that [AZ] was able to offend in such a manner shows that he was capable of breaching innumerable boundaries as to what is viewed as acceptable."
"I conclude that [AZ] displays no evidence of major mental disorder ... But may display some traits suggestive of personality disruption that could have interacted with his subsequent offending behaviour. [...] I have attempted to offer some tentative initial formulation of [AZ’s] offending behaviour - though the nature of the offence is contradictory to many of his experiences and difficult to understand."
"A sentence is unduly lenient, we would hold, where it falls outside the range of sentences which the judge, applying his mind to all the relevant factors, could reasonably consider appropriate."
