“In considering the seriousness of any offence, the court must consider the offender’s culpability in committing the offence and any harm which the offence caused, was intended to cause or might foreseeably have caused.”

It cannot, we are confident, have been the intention of Parliament to subject defendants to the risk of having their sentences increased -- with all the anxiety that that naturally gives rise to -- merely because in the opinion of this court the sentence was less than this Court would have imposed."
