Reduction of sentence for early guilty plea
The Sentencing Act 2017 (SA) sets out a scheme that provides for a reduction in sentence for early guilty pleas. It provides for a reduction of sentence by up to 40% for early guilty pleas in the Magistrates Court [Sentencing Act 2017 (SA) s 39] and up to 35% (up to 25% for serious indictable offences) in the higher courts [s 40].
In determining the relevant reduction in sentence, the court can consider [ss 39, 40]:
- the proportionality of the reduction of sentence as compared to the seriousness of the offence
- the stage in the proceedings at which the defendant first indicated their intention to plead guilty
- whether the defendant was initially charged with a different offence and whether negotiations occurred with the prosecution in relation to the additional offence(s)
- in the case where a defendant has been charged with more than one offence, whether the defendant has pleaded guilty to the other offences
- whether the defendant was made aware of any relevant matters which would have enabled them to plead guilty at an earlier stage
- whether the defendant could not have reasonably pleaded guilty at an earlier stage because of circumstances beyond their control
- whether the defendant disputed the factual basis of the plea, a hearing occurred in relation to the dispute, and the dispute was not resolved in favour of the defendant
- if the prosecution satisfies the court that the defendant intentionally concealed the commission of the offence, and if so, for how long the concealment lasted
- whether the prosecution's case against the defendant is so overwhelming that a reduction in sentence by the contemplated percentage would be so inappropriate that it would, or may, affect public confidence in the administration of justice
- whether any genuine remorse on behalf of the defendant is so lacking that a reduction in sentence by the contemplated percentage would be so inappropriate that it would, or may, affect public confidence in the administration of justice.
Section 41 of the Sentencing Act 2017 (SA) outlines the process the court must follow in applying sentencing reductions.
