Mitigating factors are those which, in the court's opinion, decrease the culpability of the offender or decrease the extent to which the offender should be punished. A plea of guilty by an offender is expressly identified as constituting a mitigating factor by s 8(2) and the earlier in proceedings that it is made, or an indication is given that it will be made, the greater the mitigation. You have pleaded guilty to the charge of manslaughter but only after the trial of the other charges against you resulting in three of the four convictions for which you are now being sentenced.
Johnson [sic], of course, had pleaded guilty to the first three offences charged against him in the indictment, namely the commission of an offence in a dwelling in circumstances of aggravation and the two charges of unlawful detention. It was submitted by your counsel at the original trial there was a good, compelling basis justifying your pleas of not guilty to these charges and that it was to ensure that the evidence of the entire episode emerged in order to reveal, so it was submitted, that your role was quite different from, and subsidiary to, that of Johnson [sic] and hence less culpable. I must say, however, that in relation to the convictions for the first three charges on the indictment I do not entirely accept that submission. Johnson [sic] played the dominant role but I consider that your role was only slightly less culpable than that of Johnson [sic] in relation to those three offences.
The conclusion of the trial and the fact that the DPP has accepted your plea of guilty to the lesser crime of manslaughter does mean, however, that you were successful in pleading not guilty to the charge of murder and in defending yourself at that trial. There is nothing to suggest that the DPP would have accepted a plea by you to manslaughter earlier than he did. Accordingly, your plea of guilty to this crime entered shortly after the order that you be remanded for retrial on the charge of murder, does, in my view, come within s 8(2) of the Sentencing Act and entitles you to a reduction in the sentence for which you would otherwise be liable for the crime of manslaughter. Nor is it insignificant that your plea has avoided the need for a retrial and the expense and effort by the State and the inconvenience to the many witnesses that that would have involved. You are, accordingly, entitled to some credit because of that plea in relation to the sentence to be imposed for that offence but, as already indicated, not in respect of the other offences of which you have been convicted [42] - [44].
