"An appellate court does not interfere with the sentence imposed merely because it is of the view that that sentence is insufficient or excessive. It interferes only if it be shown that the sentencing Judge was in error in acting on a wrong principle or in misunderstanding or in wrongly assessing some salient feature of the evidence. The error may appear in what the sentencing Judge said in the proceedings, or the sentence itself maybe so excessive or inadequate as to manifest such error ... Although an error affecting the sentence must appear before the appellate court will interfere in an appeal either by the Crown or by a defendant, a Crown appeal raises consideration which are not present in an appeal by a defendant seeking a reduction in his sentence. Crown appeals have been described as cutting across 'time honoured concepts of criminal administration': per Barwick CJ, Peel v The Queen [1971] HCA 59; (1971) 125 CLR 447at 452. A Crown appeal puts in jeopardy 'the vested interests that a man has to the freedom which is his, subject to the sentence of the primary tribunal:' per Isaacs J, Whittaker v The King [1928] HCA 28; (1928) 41 CLR 230 at 248. The freedom beyond the sentence imposed is, for the second time, in jeopardy on a Crown appeal against sentence. It was first in jeopardy before the sentencing court".
