The view was adopted in Renzella that pre-sentence detention to which s.18 does not apply can, in some circumstances at least, as a matter of justice be taken into account in the exercise of the court's discretion.
Nevertheless, as Callaway, J.A., when considering the manner in which this discretionary exercise is to be performed, pointed out in R. v. Kotzmann [1999] VSCA 27; [1999] 2 VR 123 -
"There can be no question of a person on remand who is subsequently acquitted acquiring a kind of bank balance on which to draw in relation to subsequent offences unconnected with the reason for custody ... ." (at 137)
It is evident from the subsequent cases that have come before this Court, that the reduction in an otherwise appropriate sentence to take account of what is often referred to as "dead time" is not a mathematical exercise and in a number of them allowance has been made for less than the full period involved. It is also to be noted that in none of those to which our attention has been drawn has any reason been given for the decision to discount by less than the full period.
The proper approach to be adopted with respect to pre-sentence detention not falling under s.18(1) was considered by Winneke, P., who expressed the view in R v Chimirri, with which the other members of the Court agreed, that -
" ... remand in custody in the circumstances that we have described counts as time served, in a general sense, awaiting trial on this charge, and it falls to us to consider, in fixing a sentence which we think is appropriate both to the circumstances of the crime itself and to the circumstances that we have been describing, and to fix a sentence which we think fits all the necessary components of this offence.""[5]
In other words, the fact that an individual has been detained unconvicted, albeit for unrelated matters, for some time prior to the imposition of sentence is a relevant consideration in the determination of the appropriate disposition of the matter before the court. Obviously the overall period of incarceration that would result from the imposition of a further period of imprisonment must be taken into account for more than one sentencing purpose. However, there is no need to expatiate on this aspect, as I suggest the reasons are obvious.
