Battery

Offensive and intentional contact, direct or indirect, which causes injury.

Offensive and intentional contact, or physical force, applied directly or indirectly.

Intentional, unwanted physical contact with a person or a person's clothing.

Battery is a crime as well as an actionable tort.

Although legal theorists argue that injury is not a requirement to make out a tort or personal injury case for battery, de minimis non curat lex would likely extinguish most such claims.

A battery is generally preceded by the distinct crime or tort of assault and is often defeated by a defence of consent, known as volenti non fit injuria. For example, an adult who freely agrees to a street fight cannot later complain of assault or battery as a result of a shiner.
