Legal Principles
A sentence is unduly lenient if it falls outside the range a judge could reasonably consider appropriate.
Attorney-General’s Reference No 4 of 1989
Sentencing is an art, not a science; the trial judge is best placed to assess competing considerations.
Attorney-General’s Reference No 4 of 1989
Justice delayed is justice denied; delays penalize victims and offenders.
Case judgment
In sentencing those under 18, age and maturity are particularly important (no cliff edge at 18th birthday).
R v Hobbs [2018] EWCA Crim 1003
Whether a victim is particularly vulnerable due to being asleep or intoxicated is a case-specific question.
R v Bunyan [2017] EWCA Crim 872; R v Sepulvida-Gomez [2019] EWCA Crim 872; R v Husband [2021] EWCA Crim 1240
Outcomes
Leave to refer the sentence granted.
The judge wrongly categorized the assault by penetration as category 3A instead of 2A, failing to acknowledge the complainant's particular vulnerability (age, intoxication, being asleep).
Original sentences quashed.
Miscategorization of the assault by penetration led to an unduly lenient sentence.
New sentence of 3½ years' imprisonment imposed concurrently for the two counts of assault by penetration.
Reflects the seriousness of the category 2A offenses, considering mitigating factors (age, immaturity, good character, impact on child, delay).
Sentences for sexual assaults remain as originally imposed, but are no longer suspended.
Due to the length of the sentence for assault by penetration, suspension is no longer possible.
