Real Cases: How Hong Kong Courts Sentenced Indecent Assault

About these case summaries: the summaries below were prepared by this site based on our own reading and understanding of the judgments. They are not legal advice, have no legal effect, and must not be cited as authority. Cases are identified by neutral citation only, with no party names; victim anonymity is absolute — the judgments are themselves anonymised, and this article generalises every factual context further, retaining only elements with sentencing significance. Read the originals via the HKLII links. Sentences turn on the totality of each case's circumstances; every figure below is what the cited case actually decided, never a prediction for any other case. Our full verification process for case content — full-text reading of every judgment, corrigendum checks and independent human review — is set out in our methodology .
A hypothetical scenario
Imagine a man charged with indecent assault said to have happened in an MTR carriage. Whether it is the accused or his family asking, the first question is the same: "what do these cases usually mean — immediate prison?" Indecent assault (Crimes Ordinance, s. 122) carries a maximum of 10 years, but actual sentences span an enormous range — weeks to years. Eight real judgments show how the courts placed cases along that spectrum.
The baseline: an established band for public-transport cases
Hong Kong has a long-standing band for opportunistic indecent assault on public transport (from a 1990 Attorney General's review that predates the HKLII database; both cases below quote it in full): 2 to 4 weeks' immediate imprisonment for a first offender on a guilty plea; a starting point of 21 to 42 days after trial.
- In [2023] HKCFI 1323 (CFI magistracy appeal, 2023) — a single indecent assault on an adult woman in an MTR carriage, convicted after trial — the magistrate took 21 days as the starting point (the bottom of the band); appeals against conviction and sentence were both dismissed ( judgment ).
- In [2021] HKCFI 2987 (CFI magistracy appeal, 2021) — an indecent assault on a female railway staff member at her workplace, with related criminal intimidation — the assault carried a 4-week starting point, within a total of 4 months plus 4 weeks; the appeal was dismissed ( judgment ).
In these decided cases, in other words, even a single, non-violent opportunistic assault normally meant immediate custody — deterrence in public places and on public transport recurs throughout the judgments.
Pattern 1: appellate courts cut sentences that overshot
A striking feature of this category is how often appeal courts corrected sentences that departed from the band:
- In [2022] HKCFI 850 (CFI, 2022) — an indecent assault on a 13-year-old girl in an MTR carriage, convicted after trial — the magistrate's 3-month starting point was held manifestly excessive; the court, restating the band, substituted 35 days (above the basic band because the victim's age aggravated) ( judgment ).
- In [2021] HKCFI 150 (CFI, 2021) — a one-off assault on an adult woman by an instructor during a massage in a private setting — the magistrate had lifted the starting point to 6 months for breach of trust, sentencing 4 months. The appeal court held it was "not a clear case of breach of trust" and substituted 2 months ( judgment ).
- In [2022] HKCFI 1820 (CFI, 2022) — a tutorial-centre operator's assault on a girl student — 18 months after trial was held excessive and 10 months substituted ( judgment ).
Note both directions: genuine aggravation (victim age, a real relationship of trust) lawfully pushed sentences above the basic band — but where the aggravation was not made out, the appellate courts intervened.
Pattern 2: the Secretary for Justice reviews lenient sentences too
In [2023] HKCA 1253 (Court of Appeal, 2023) — guilty pleas to two indecent assaults on a colleague who was drunk and asleep (unable to resist) — the magistrate had imposed 12 months' probation. On the SJ's review, the Court of Appeal held "an immediate custodial sentence is the only suitable option", adopted starting points of 3 months and 18 months, applied the one-third plea discount and allowances for the 8 months of completed probation and the review discount, and substituted 8 months' imprisonment overall ( judgment ). The same review mechanism appeared in this series' dangerous-driving article — sentencing gets corrected in both directions.
Pattern 3: the serious end runs to years
Section 122's 10-year maximum exists for the other end of the spectrum:
- In [2022] HKCA 1611 (Court of Appeal, 2022) — an indecent assault count tried alongside graver sexual offences — the judge adopted a basic starting point of 2½ years on the s. 122 count, enhanced to 4 years for multiple aggravating factors, within an overall sentence measured in years; leave to appeal against sentence was refused ( judgment ).
- In [2023] HKCA 1359 (Court of Appeal, 2023) — a home-intrusion case involving indecent assault and indecent conduct towards a 12-year-old girl, on guilty pleas — the court took 10½ years as the overall starting point for the sexual offending (no separate penalty on the indecent assault count, which was subsumed), reduced by one-third to 9 years; leave to appeal was refused ( judgment ).
The eight cases at a glance
| Case | Court / year | Context (generalised) | Actual outcome |
|---|---|---|---|
| [2023] HKCFI 1323 | CFI (appeal), 2023 | Single assault in a train carriage, after trial | 21-day starting point (bottom of band); appeal dismissed |
| [2021] HKCFI 2987 | CFI (appeal), 2021 | Workplace assault + criminal intimidation | 4 weeks on the assault; 4 months + 4 weeks total |
| [2022] HKCFI 850 | CFI (appeal), 2022 | Assault on a 13-year-old in a carriage | 3 months reduced to 35 days |
| [2021] HKCFI 150 | CFI (appeal), 2021 | Private setting; trust uplift not made out | 4 months reduced to 2 months |
| [2022] HKCFI 1820 | CFI (appeal), 2022 | Tutorial setting, student victim | 18 months reduced to 10 months |
| [2023] HKCA 1253 | Court of Appeal, 2023 | Incapacitated colleague; SJ review | Probation replaced with 8 months' imprisonment |
| [2022] HKCA 1611 | Court of Appeal, 2022 | Tried with graver sexual offences | s. 122 starting point 2½ years enhanced to 4 |
| [2023] HKCA 1359 | Court of Appeal, 2023 | Home intrusion; 12-year-old victim; pleas | 9 years overall (assault count subsumed) |
What moved sentences in these cases
- Victim age: minority was a significant aggravator ([2022] HKCFI 850 above the basic band; [2023] HKCA 1359 in years).
- Relationships of trust: an uplift where genuinely established (the tutorial case); corrected on appeal where not ([2021] HKCFI 150).
- Victim incapacity: [2023] HKCA 1253 — immediate custody "the only suitable option".
- Gravity and persistence of the conduct: the gap between a single touch and serious violation was the gap between weeks and years.
- Guilty pleas: consistently earned the one-third discount — but did not convert custody into non-custody; a probation order was overturned on review in these cases.
If you or a family member is involved in such a case
- Rights on arrest: rights if arrested ; bail: bail guide .
- Indecent assault tried in the Magistrates' Courts falls within the Duty Lawyer Scheme — see legal aid and duty lawyer .
- Conviction issues (identity, intent, consent) and mitigation are intensely fact-specific — early criminal-law advice matters to both sides of such cases.
- If you are a victim: indecent assault is a crime you can report directly to the Police, and victim identity is protected by anonymity in the proceedings.
