7 Whilst the learned magistrate's decision to obtain a pre-sentence report was entirely consistent with these principles, he directly contravened them by the course he adopted immediately after he had directed the provision of that report. Without foreshadowing the course he had in mind or explaining what he had in mind, the learned magistrate remanded the applicant in custody until 11 October 2006, a period of 26 days, for the preparation of the report. Although the applicant had on past occasions failed to comply with the terms of his bail, he had appeared to the charges being dealt with by the learned magistrate on the last three occasions on which they were before the court, that is, on 2 June 2006, 10 July 2006 and 15 September 2006. The applicant was in employment and had family in Tasmania. Bearing in mind the sentencing principles to which I have referred, there was every reason to continue the applicant's bail and no reason to remand him in custody. The practical effect of the course adopted by the learned magistrate was to impose an immediately effective sentence of 26 days' imprisonment on the applicant. When the learned magistrate came to finally sentence the applicant, he was obliged to take into account the period during which the applicant had been held in custody, Sentencing Act 1997, s16(1). The course adopted by the learned magistrate largely denuded the pre-sentence report that was to be provided of any real utility, and demonstrated that notwithstanding the absence of that report or any detailed information on the applicant's personal circumstances, the learned magistrate had concluded that it was appropriate to imprison the applicant and expose him to the corrupting influences of incarceration. This was plainly an error and counsel for the respondent concedes it to be so. It was an error that was compounded by the learned magistrate's failure to give the applicant notice of what he had in mind and an opportunity to dissuade him from adopting that course. In Parker v Director of Public Prosecutions [1992] 28 NSWLR 282, Kirby P, agreed with by Handley and Sheller JJA, explained at 296 that where a sentencer is contemplating a custodial sentence, he or she should so indicate in order to give the offender a fair opportunity to present contrary argument and persuade the sentencer to take a different course. This was not done by the learned magistrate. Returning to the precipitate decision to remand the applicant in custody for 26 days, I mention that incarceration for that period is a not insignificant penalty for common assault. With effect from 15 December 2003, the maximum penalties for common assault were increased from a fine of $500 or imprisonment for six months to a fine of $2,000 or imprisonment for twelve months. In Sentencing in Tasmania, 2nd ed, Federation Press, Professor Warner analyses the sentences imposed for common assault in southern Tasmania in 1999 and 2000 and, at par14.207, she says that a fine and dismissal were the most common outcomes, with about 22 per cent of offences attracting a sentence of imprisonment, the median sentence being one month. Against the background of this range of penalties, albeit a range based on sentences imposed before the 15 December 2003 increase to the applicable maximum penalties, there was no justification for concluding, prior to the receipt of a pre-sentence report detailing the applicant's personal circumstances, that his offences warranted a penalty of at least 26 days' imprisonment.
