"In my opinion Mr Galea's cognitive problems are not satisfactorily explained simply on the basis of his being ill-educated. I have relatively little information to hand but it would seem that the incident of head injury when he was around 10 years of age very likely has left him with a degree of persisting brain injury. ... Mr Galea certainly seems not to have been motivated towards his involvement in drug trafficking because of any personal difficulties with substance abuse. Rather this man seems to have acted out of a misguided sense of obligation to his friend and I believe it is a reasonable proposition that this cognitively impaired man has a limited capacity for consistently exercising proper social judgement, which ought to be regarded as a mitigating factor. ... Given the probability that this man is actually brain injured and, furthermore, that it is my view that the brain injury does have some significance in relation to his offending, I believe Mr Galea would be a candidate for at least partial escaping of general deterrent aspects of sentencing. While he is cognitively impaired, that is not so severe such that specific deterrent aspects of sentencing would be lost to him. As indicated above, there are continuing rehabilitative issues to be addressed. Mr Galea thoroughly castigates himself in relation to his ill-considered conduct which has led to his current charges and, while on the basis of his past history he would have to be regarded as at some risk of reoffending, it would seem unlikely that he might be tempted precisely towards drug trafficking again."
