What this dot point is asking
OCR Component 1 Section B requires you to know the five non-fatal offences against the person, arranged as a ladder of increasing seriousness: assault and battery at common law, then section 47, section 20 and section 18 of the Offences Against the Person Act 1861. The skill is to match each act in a scenario to the right offence and apply its actus reus and mens rea for AO2.
The answer
Assault and battery
Section 47: assault occasioning actual bodily harm
Section 47 of the Offences Against the Person Act 1861 makes it an offence to commit an assault or battery that occasions actual bodily harm (ABH). ABH is harm that is more than transient and trifling (Miller); it includes bruising, a black eye, broken teeth and recognised psychiatric injury (Chan-Fook), but not mere emotions. The mens rea is the same as for the assault or battery: the defendant need not intend or foresee the ABH itself (Savage; R v Parmenter). It is an either-way offence with a maximum of five years.
Section 20: malicious wounding or inflicting GBH
Section 20 makes it an offence to unlawfully and maliciously wound or inflict grievous bodily harm. The actus reus is a wound (a break in both layers of the skin, JCC v Eisenhower) or grievous bodily harm, meaning really serious harm (DPP v Smith; the victim's age and health may be relevant, R v Bollom). The mens rea ("maliciously") requires intention or recklessness as to some (not serious) harm (Mowatt; Parmenter). It is either-way with a maximum of five years.
Section 18: wounding or causing GBH with intent
Section 18 has the same actus reus as section 20 (a wound or GBH) but a more demanding mens rea: a specific intent to cause grievous bodily harm, or an intent to resist or prevent lawful arrest with recklessness as to some harm (Belfon; Morrison). Because of this specific intent, section 18 is the most serious of the ladder, indictable only, with a maximum of life imprisonment.
Examples in context
A strong answer never treats a scenario as one offence: it splits the facts and climbs the ladder act by act.
Try this
Q1. Explain the actus reus and mens rea of the offence under section 47 of the Offences Against the Person Act 1861. [12 marks]
- What the marker wants. Precise AO1: an assault or battery (the actus reus) occasioning actual bodily harm (more than transient and trifling, Miller; includes psychiatric harm, Chan-Fook), with the mens rea being only that for the assault or battery (Savage).
Q2. During a robbery, Liam slashes a guard's arm with a knife, leaving a deep wound, intending to stop the guard chasing him. Discuss Liam's liability for the non-fatal offences. [20 marks]
- Cue. An AO2 application: a wound (Eisenhower) supports s20 or s18; the specific intent here (to resist or prevent his arrest, with recklessness as to harm) points to section 18 (Belfon, Morrison), so conclude on the most serious offence the facts support.

OCR H418/01 2020 (Section B scenario)20 marksIn a queue, Sam raises his fist at Tara, who flinches; he then punches her, giving her a black eye and a deep cut needing stitches. Intending to teach her a lesson, he stamps on her hand, breaking several bones. Discuss Sam's liability for the non-fatal offences against the person. [Section B legal scenario, AO2]Show worked answer →
A scenario testing AO2 application of the ladder of non-fatal offences. Work up the ladder, applying each offence to a distinct act.
Raising the fist: assault (Ireland, Constanza). The actus reus is causing Tara to apprehend immediate unlawful force; flinching shows apprehension. Mens rea: intention or recklessness as to causing that apprehension.
The punch causing a black eye and a cut needing stitches: this is more than transient harm, so s47 ABH (Miller, the harm need not be serious but more than trifling, Chan-Fook includes recognised psychiatric harm). A deep cut breaking both layers of skin could be a wound for s20 (JCC v Eisenhower). Mens rea for s47 is the mens rea for the assault or battery (Savage); for s20 it is intention or recklessness as to some harm (Mowatt, Parmenter).
Stamping to break bones with intent to cause serious harm: s18 GBH with intent (DPP v Smith defines GBH as really serious harm; the specific intent to cause GBH is the key, Belfon). Broken bones are GBH.
A top answer matches each act to the right offence, applies the actus reus and mens rea, and concludes on each.
OCR H418/01 2022 (Section A style)12 marksExplain the difference between the offences under sections 20 and 18 of the Offences Against the Person Act 1861. [a medium-tariff Section A question; true tariff varies between 10 and 15 on the real paper]Show worked answer →
A Section A knowledge question, mainly AO1, rewarding a precise comparison of actus reus and mens rea.
Actus reus. Both require a wound (breaking both layers of skin, Eisenhower) or grievous (really serious) bodily harm (DPP v Smith). The actus reus is essentially the same.
Mens rea is the key difference. Section 20 requires intention or recklessness as to causing some harm (Mowatt, Parmenter), a basic-intent offence. Section 18 requires a specific intent: either intention to cause grievous bodily harm, or intention to resist or prevent lawful arrest with recklessness as to harm (Belfon, Morrison). Section 18 is therefore more serious and carries a maximum of life, against five years for s20.
A top answer states the shared actus reus and contrasts the mens rea precisely.
