What are the points to prove for sexual assault under s.3 Sexual Offences Act 2003?
Sexual assault (s.3(1) Sexual Offences Act 2003) requires: (1) A intentionally touches another person, (2) the touching is sexual (s.78), (3) the other person does not consent (s.74), and (4) A does not reasonably believe the other person consents.
It is triable either way — the maximum on conviction on indictment is 10 years' imprisonment; on summary conviction it is 6 months' imprisonment (s.3(4)).
Sexual assault is defined by s.3(1) Sexual Offences Act 2003: intentionally touching another person, where the touching is sexual, the other person does not consent to the touching, and the defendant does not reasonably believe that the other person consents. Each element has its own statutory definition (ss.74, 78), reproduced verbatim below. It is educational reference, not a charging decision — verify against current law, CPS charging guidance and force policy.

Points to prove — statutory elements
Reproduced verbatim from the Act as published on legislation.gov.uk. These are the statutory elements, not a paraphrase — confirm the up-to-date text and any amendments at the source.
(1) A person (A) commits an offence if—
(a) he intentionally touches another person (B),
(b) the touching is sexual,
(c) B does not consent to the touching, and
(d) A does not reasonably believe that B consents.
(2) Whether a belief is reasonable is to be determined having regard to all the circumstances, including any steps A has taken to ascertain whether B consents.
(3) Sections 75 and 76 apply to an offence under this section.
(4) A person guilty of an offence under this section is liable—
(a) on summary conviction, to imprisonment for a term not exceeding 6 months or a fine not exceeding the statutory maximum or both;
(b) on conviction on indictment, to imprisonment for a term not exceeding 10 years.
For the purposes of this Part, a person consents if he agrees by choice, and has the freedom and capacity to make that choice.
For the purposes of this Part (except sections 15A , 66B to 66D and 71 ), penetration, touching or any other activity is sexual if a reasonable person would consider that—
(a) whatever its circumstances or any person’s purpose in relation to it, it is because of its nature sexual, or
(b) because of its nature it may be sexual and because of its circumstances or the purpose of any person in relation to it (or both) it is sexual.
Powers of arrest & search
A constable may arrest without warrant anyone whom they have reasonable grounds to suspect of committing sexual assault, where an arrest is necessary on one of the s.24(5) grounds (PACE 1984 s.24). There is no separate statutory power of arrest in the Sexual Offences Act 2003 for this offence.

Key points:
Touching is widely defined and includes touching another person with any part of the body, or with anything else. Touching can be through clothing. In R v H (Karl Anthony) [2005] EWHA Crim 732 the Court of Appeal held that the touching of an individual’s clothing was sufficient to amount to ‘touching’ for the purposes of section 3.
Touching includes touching amounting to penetration, for example, kissing. Where there is sufficient evidence, penile penetration of the vagina, anus or mouth should be charged as rape and penetration of the vagina or anus with any part of a person’s body or other object should be charged as assault by penetration.
Sexual assault is an either way offence and attracts a maximum 10 year sentence on indictment.
Charging practice:
If touching does not occur, then consider an attempt.
Various activities previously covered by the offence of ‘indecent assault’ now fall within the definitions of offences under the 2003 Act (for example, assault by penetration, child sex offences and vulnerable adults subjected to a sexual assault). This means that the offence of sexual assault (section 3) will largely now be used in relation to lesser forms of sexual assault, than previously.
The exact nature of the sexual touching involved will be a key factor in assessing the seriousness of the offence. Prosecutors should refer to the harm and culpability factors and the aggravating and mitigating factors set out in the Sentencing Council's Sexual Offences (“sentencing guidelines”) when considering seriousness and the appropriate sentencing category for the offending.
The definition of sexual is contained within section 78 of the Sexual Offences Act 2003 and applies to all offences in part 1 of the Act, with the exception of section 71 (sexual activity in a public lavatory).
Penetration, touching or any other activity is sexual if a reasonable person would consider that:
whatever its circumstances or any person’s purpose in relation to it, it is because of its nature sexual, or
because of its nature it may be sexual and because of its circumstances or the purpose of any person in relation to it (or both) it is sexual.
In deciding whether an activity is sexual look first at the nature of the activity. If the activity is by its nature sexual (for example, sexual intercourse, masturbation) then it is sexual for the purposes of the legislation.
Where the nature of the activity may or may not be sexual prosecutors should consider the circumstances or purpose (or both) of the defendant in deciding whether it is sexual.
Where the nature of the act cannot be sexual, it is not made sexual by a person having a secret fetish.
Touching of clothing might be sexual as in the case of R v H [2005] EWCA Crim 732.
- "Touching" is broadly defined by s.79(8): it includes touching with any part of the body, touching with anything else, touching through anything, and in particular includes touching amounting to penetration.
- Consent is defined in s.74: a person consents if they agree by choice, and have the freedom and capacity to make that choice. Sections 75 and 76 set out evidential and conclusive presumptions about consent that can apply in specified circumstances — they are not reproduced as elements on this card but are relevant to the investigation.
- A conviction for sexual assault attracts notification requirements (registration as a sex offender) in specified circumstances under Part 2 of the Act.
