Original judgment source is linked above.
(1) an appellate court cannot substitute its own opinion for that of the sentencing court merely because the appellate court would have exercised a sentencing discretion differently. Appellate intervention occurs only if the appellant demonstrates either an express or implied material error;
(2) express error involves acting on a wrong principle; for example, by mistaking the law or facts or taking into account an irrelevant matter. Implied error arises where the end result is so unreasonable or unjust that the court must conclude that a substantial wrong has occurred;
(3) implied error will arise if a sentence is manifestly excessive. In order to determine whether a sentence for an individual offence is manifestly excessive or inadequate, the offence should be viewed in light of the maximum sentence prescribed by law for the crime, the standards of sentencing customarily imposed with respect to it, the place that the criminal conduct occupies in the scale of seriousness of crimes of that type, and the offender's personal circumstances; and
(4) the range of sentences customarily imposed for a crime does not establish the range of a sound exercise of the sentencing discretion. Sentences customarily imposed in comparable cases provide a yardstick or reference point for ensuring broad consistency in sentencing, bearing in mind the scope for significant variations in relevant sentencing factors, and that there is no single correct sentence.
Plea of guilty, sentence may be reduced in case of
(1) In this section -
fixed term has the meaning given in section 85(1);
head sentence, for an offence, means the sentence that a court would have imposed for the offence if -
(a) the offender had been found guilty after a plea of not guilty; and
(b) there were no mitigating factors;
victim has the meaning given in section 13.
(2) If a person pleads guilty to a charge for an offence, the court may reduce the head sentence for the offence in order to recognise the benefits to the State, and to any victim of or witness to the offence, resulting from the plea.
(3) The earlier in the proceedings the plea is made, the greater the reduction in the sentence may be.
(4) If the head sentence for an offence is or includes a fixed term, the court must not reduce the fixed term under subsection (2) -
(a) by more than 25%; or
(b) by 25%, unless the offender pleaded guilty, or indicated that he or she would plead guilty, at the first reasonable opportunity.
(5) If a court reduces the head sentence for an offence under subsection (2), the court must state that fact and the extent of the reduction in open court.
(6) This section does not prevent the court from reducing the head sentence for an offence because of any mitigating factor other than a plea of guilty.
(1) in respect of Mr Summers, a fine of $18,000; and
(2) in respect of Mr Roccisano, a fine of $14,000.
