In my view, the circumstances here are clearer than those that applied in Armistead. Here the act of possession the subject of charge 11 was not based upon conduct distinct from the conspiracy to commit armed robbery. It was based upon conduct that took place during the conspiracy and was only discovered when the car in which Kamal was travelling, with Murrell and Ngaa, towards the JD's sports bar, was obstructed by the police when the conspiracy was detected. Moreover, it is also apparent that the judge took into account the conduct that he relied upon in support of charge 11, Kamal's possession of the firearm, as an aggravating factor in the conspiracy to commit armed robbery. In assessing the seriousness of the offending, the judge considered the fact that 'there was a loaded Smith & Wesson revolver found' alongside other aggravating factors including the theft of multiple cars, the fact that disguises and cable ties were to be used, and the consideration that the armed robbery was to take place in broad daylight in a main street of Ballarat. Having treated the possession of the firearm as an aggravating factor in the conspiracy, it was incumbent on the judge not to punish again for the very same conduct.

However, while the maximum penalty for the possession offence is substantial, the imposition of a sentence of four years for possession of a firearm would, as Redlich JA noted in Armistead, usually be reserved for those occasions on which the possession was linked to its use for criminal activity. In my view, the severity of the sentence on charge 11 indicates that the judge took into account the association of the possession of the firearm with criminal activity in sentencing Kamal under charge 11 while also taking into account the possession of the firearm in sentencing for that very same criminal activity.
Moreover, the circumstances here go beyond mere overlap. Analogously to the observations made by Weinberg JA in Kruzenga, here the possession of the revolver was for one reason only, for use in the planned armed robbery. It was thus necessary for the judge to take great care not to treat the possession of the revolver as both an aggravating feature of the conspiracy and a separate and distinct offence requiring a significant measure of punishment as well as a substantial amount of cumulation. Yet there is no reference made in the judge's sentencing reasons to any moderation of sentence to avoid the possibility of doubly punishing Kamal.
In my view, the judge failed to take the care required in sentencing Kamal to four years' imprisonment on charge 11, with a cumulation of one year, when he had taken the possession of the firearm into account as an aggravating factor in sentencing Kamal to six years on charge 1, the conspiracy offence. I consider that the judge erred in doubly punishing Kamal. At the hearing of the appeals, the Crown conceded that an element of double punishment had crept into the sentence of four years. It submitted, however, that some degree of cumulation was necessary and that one year might be appropriate.
The Crown further submitted that, as the double punishment argument was not advanced on the plea, Kamal should therefore be prevented from raising it on the appeal. This submission should be rejected. There was no obligation on Kamal to make submissions in anticipation that the judge would fall into the error of doubly punishing him by treating the possession of the firearm as an aggravating feature of the conspiracy offence without modifying the sentence he imposed on the possession offence, in the absence of any intimation that this is what the judge intended to do. In light of the nature of the error, and the obligation that rested on the judge to take the necessary care to avoid doubly punishing Kamal, I consider that a failure to make the relevant submission on the plea ought not preclude Kamal from relying on the submission on his appeal.
