Step 1: Public Prosecutor v Ng Whye Quan
Parity treats like co-offenders alike in substance: the High Court held an offender held in custody before conviction is not in a like position to a co-offender who was not, raising a rioting sentence to 18 months.
As a matter of common sense, an offender who has undergone a pre-conviction custodial period is not at all in a like position as compared to a co-offender who has not.
From the judgment When applying parity between co-offenders, does it matter whether one sentence was backdated for time in custody?
Yes. The High Court held that parity is applied by substance over form, not the gross length of the terms, and allowed the prosecution's appeal, raising the rioting sentence from 13 months to 18 months' imprisonment.

Step 2: Soh Chee Wen v Public Prosecutor
Past sentences guide only as far as their reasoning can be seen: the Court of Appeal gave little weight to sentencing precedents without written grounds and dismissed both appeals against aggregate terms of 36 and 20 years.
sentencing precedents without grounds or explanations will carry little, if any, weight because they are unreasoned.
From the judgment Can defence counsel be made to pay costs personally for unfounded allegations of bias against a trial judge?
Yes, here. The Court of Appeal ordered the second appellant's counsel to pay the Prosecution $10,000 personally for unfounded bias allegations, made without instructions and later falsely downplayed, which caused it unnecessary costs, and dismissed both appeals against sentence.

Step 3: Public Prosecutor v Randy Rosigit
Sentencing frameworks give structure, clarity and consistency rather than fine-grained analysis: the High Court laid down a framework for possessing child abuse material and replaced six weeks' imprisonment with eight months.
In essence, sentencing is not a fine-grained analytical exercise but a broader inquiry that is designed to provide structure, clarity and consistency.
From the judgment How should possession of child abuse material be sentenced?
By weighing harm and culpability in a framework the High Court laid down. Applying it, the court allowed the Prosecution's appeal and replaced six weeks' imprisonment with eight months' imprisonment.

Step 4: Public Prosecutor v Tan Shay Howe
Ranges set in one case are not a benchmark for all: the High Court held the Ho Man Yuk ranges were no generic sentencing benchmark, adopted the Huang Ying-Chun framework for self-laundering, and raised both sentences.
we clarify that the Ho Man Yuk sentencing ranges ought not to be taken as a generic sentencing benchmark.
From the judgment What sentencing framework applies to self-laundering offences under s 54(1) of the CDSA?
The court adopted the five-step Huang Ying-Chun framework and, finding the two CDSA sentences manifestly inadequate, allowed the Prosecution's appeal, enhancing them to 22 and 26 months' imprisonment for an aggregate of 52 months and two weeks.

Step 5: Public Prosecutor v Zheng Jia
A framework can make custody the presumptive starting point: for a director's failure of reasonable diligence under s 157(1) of the Companies Act of the kind before it, the High Court held the custodial threshold presumptively crossed.
In our judgment, the custodial threshold will be presumptively crossed for offences of the present category for the reasons set out at [44]–[47] above and the onus will be on the director to explain why that should not operate in his or her case.
From the judgment Does a professional nominee director who exercises no oversight at all face jail rather than a fine?
Yes, presumptively. The High Court held such a director acts knowingly, if not intentionally, set a framework in which the custodial threshold is presumptively crossed, and allowed the Prosecution's appeal, imposing ten months' imprisonment in aggregate.

Step 6: Jeremiah Ng En You (Huang Enyou) v Public Prosecutor
Placing an offence in a band means looking at the offence as a whole, not one favourable factor: the High Court set new frameworks and upheld seven years' imprisonment for a drunk driver's dangerous driving causing death.
However, it is not open to an offender to isolate one factor which may, on its own, indicate a lower level of culpability and thereafter argue that the offence should fall within a lower band.
From the judgment Do the guilty plea reduction guidelines apply to a drunk driver who caused death by dangerous driving?
Yes. The High Court held the guidelines apply, set new sentencing frameworks, placed the fatal charge at ten years' imprisonment, applied the full 30% reduction, and dismissed the appeal, upholding seven years' imprisonment.

Step 7: Gao Xiong v Public Prosecutor
For an attempt, the incomplete offence discount comes with the offence-specific factors: the Court of Appeal preferred the three-staged Andrew Kumaravel approach and, for his abuse of process on appeal, cut the plea discount from 20% to 5%.
it is more principled to consider the incomplete offence discount, which engages offence-specific considerations, immediately after (and, in a sense, together with) the other offence-specific considerations relating to the completed offence, separately from the offender-specific considerations.
From the judgment How should a court discount the sentence for an attempted offence?
By a percentage, between the offence-specific and offender-specific stages. The Court of Appeal dismissed the appeal and, for his abuse of process on appeal, enhanced the attempted rape sentence by cutting the plea discount from 20% to 5%.

Step 8: Public Prosecutor v Xavier Yap Jung Houn
The one-transaction rule usually makes sentences run concurrently, but the High Court held it not engaged where the two offences were against two different victims, and ran two seven-year sentences consecutively.
the one-transaction rule states that where two or more offences are committed in the course of a single transaction, all sentences in respect of those offences should generally be ordered to run concurrently rather than consecutively.
From the judgment Should sentences for killing two children in one episode run concurrently?
No, here. The High Court held the one-transaction rule did not apply because two distinct lives were taken, and sentenced the father to seven years' imprisonment per charge, running consecutively for 14 years.

Step 9: Public Prosecutor v DEK
The totality principle checks the global sentence against the most serious offence and for a crushing effect: the High Court declined judicial mercy despite the offender's advanced age and terminal illness, and imposed a global sentence of 21 years.
The first limb requires the sentencing court to examine whether the global sentence it contemplates is substantially above the normal level of sentences for the most serious of the individual offences committed.
From the judgment Does a terminal illness earn judicial mercy for a persistent child sex offender?
No, here. He kept offending after his diagnosis. The High Court sentenced him to 21 years' imprisonment in total, reduced from 26 years under the totality principle given his age and illness, without imprisonment in lieu of caning.

Step 10: Mohamed Erzan Taib Zohri v Public Prosecutor
For young offenders rehabilitation is presumptively primary: applying the Al-Ansari/Boaz framework to scam-related offences, the High Court held a default of custody or reformative training too blunt and substituted probation in four appeals.
In our judgment, a default approach assuming a custodial sentence or RT save in exceptional cases is too blunt, bearing in mind the courts’ longstanding recognition of young offenders’ lack of maturity, the prospects of a long and productive life ahead of them, and the importance of securing their rehabilitation wherever possible.
From the judgment Should young scam offenders who handed over bank accounts normally receive custody or reformative training?
No. A custodial default is too blunt, and rehabilitation remains presumptively primary for young offenders. Allowing the appeals in part, the High Court substituted probation for reformative training in four appeals and dismissed the other three.

Step 11: Public Prosecutor v CPS
Rehabilitation can still be displaced by deterrence: for an offender who was 16 at the time of his rape offence, the Court of Appeal weighed his recalcitrance and attitude and replaced reformative training with eight years' imprisonment and caning.
Considering the above factors cumulatively, in particular the respondent’s recalcitrance and attitude towards his offending, we were of the view that rehabilitation ought to be displaced by deterrence as the predominant sentencing consideration.
From the judgment Is reformative training usually suitable for an offender who was 16 when he committed rape?
No. The Court of Appeal held that rape usually displaces rehabilitation unless exceptional circumstances are strong, allowed the Prosecution's appeal, and replaced reformative training with eight years' imprisonment and three strokes of the cane.

Step 12: Public Prosecutor v Soo Cheow Wee
A mental disorder can lower culpability: absent evidence that the offender knew the substances would make him violent, the High Court found his medical condition substantially impaired his responsibility and cut the aggregate sentence from 33 to 27 months.
in the absence of evidence that the Appellant had sufficient insight that if he ingested certain substances, this would result in violent psychotic behaviour on his part and that he nonetheless voluntarily chose to act in this way, I find his medical condition substantially impaired his responsibility and that this is a mitigating factor.
From the judgment Does a mental disorder triggered by voluntary drug use reduce a violent offender's sentence?
It can, unless the offender knew the drugs would trigger psychosis and violence. The High Court dismissed the Prosecution's appeal, allowed the offender's appeal in part, and cut the sentence from 33 to 27 months.
