Key Criminal Law Cases: Assault and Battery

Ever wondered how the law decides whether someone's threatening behaviour counts as a crime? These cases show exactly how courts draw the line between different types of violent offences.

Assault cases demonstrate that you don't need to actually touch someone to commit a crime. In Constanza (1997), 800 threatening letters were enough to constitute assault because the victim feared violence. Even silent phone calls can be assault, as shown in Ireland (1997). However, the victim must genuinely fear immediate violence - in Lamb (1967), no assault occurred because both people thought the gun wouldn't fire.

Battery cases focus on unlawful touching or contact. The famous Fagan (1968) case shows how driving onto a police officer's foot became battery when the defendant refused to move the car. Interestingly, battery can be indirect - in Martin (1881), causing a stampede by shouting "Fire!" in a theatre was still battery even though the defendant didn't touch anyone directly.

Remember: Assault is about fear of violence, whilst battery involves actual unlawful contact - even if it's indirect!

The courts have established that touching someone's clothing counts as touching them (Thomas 1985), and failing to disclose dangers like needles in pockets can create liability $DPP v Santana-Bermudez 2003$. These cases show how mens rea (criminal intent) and actus reus (criminal act) work together to establish guilt.

More serious offences like ABH (s47) and GBH $s20/s18$ build on these basic principles. Cases like Roberts (1972) show that defendants can be liable even when victims injure themselves trying to escape, whilst Burstow (1997) established that severe psychiatric harm can constitute grievous bodily harm.
