// CFA: Clarification of Mental Element in Gross Indecency Towards a Child Under 16 //
In HKSAR v F S L [2026] HKCFA 13, the CFA clarified the scope of the offences under s146 of the Crimes Ordinance, ie committing an act of gross indecency towards a child under the age of 16, and inciting a child under the age of 16 to commit an act of gross indecency towards him or her or another.
// Key finding //
Sexual gratification on the part of the offender is not an essential element of an offence under s146.
// Actus reus //
(1) Act or incitement
- D committed an act of gross indecency with or towards a child under 16; or
- D incited a child under the age of 16 to commit an act of gross indecency with or towards D or another. Incitement is an inchoate offence and is complete even if the child does not commit the act incited
(2) Gross indecency
- The act must amount to gross indecency
- Whether an act is grossly indecent is a question of fact, to be determined by whether right‑minded members of the public, applying contemporary moral standards, would regard the act as grossly indecent
// Mens rea //
P must prove that D intended to commit, or intended to incite, the act of gross indecency charged. It must be shown that D intended to commit the act “with or towards” the child. This intention would ordinarily require proof that D knew of the child’s presence and that the child could see or be aware of the act.
// Sexual gratification as an additional requirement? //
- No
- There is nothing in the wording of s146 to indicate such a requirement
- Sexual gratification is not mentioned and cannot properly be implied
- Imposing an additional requirement of sexual gratification would be inconsistent with, and would frustrate, the statutory purpose of protecting children under 16 from acts of gross indecency
- Equal protection is required whether D acts out of sexual desire, spite, anger, or an intention to humiliate the child or a parent
- Motive, including sexual gratification, may be relevant in marginal cases where there is a doubt as to whether an act is indecent, but is irrelevant where the act in question is inherently grossly indecent
