Not Be A Hostile Act
Battery need not be a hostile act. Thus, it may amount to battery to carry out surgery without consent, emergency, or justification or to kiss a woman against her will.
Battery May Be Committed On An Unconscious Person
Battery may be committed on a person not only when the person is conscious, but also while a person is unconscious, such as, when a person is asleep, or unconscious during surgery.
An Omission May Amount To Battery
An omission, especially if it persists may be a battery. For instance, a motorist, who accidentally drove his car on to a police constable's foot while parking his car commits no battery, but he commits battery, if he ignores the constable's plea to 'get off my foot'.
See Fagan v Metropolitan Police Commissioner (1968) 3 All ER 442
The defendant appellant was reversing his car whilst the complainant police constable standing in his front indicated where he should park. He then drove the car onto the policeman's foot and stopped thereon. The constable told the appellant to get off his foot and received an abusive reply. The constable repeated his request several times and the appellant finally said "Okay man, Okay" and slowly reversed off the constable's foot. He was charged with assaulting a police officer in the execution of his duty. The court held that the appellant was liable and his appeal was dismissed. The appellant's conduct could not be regarded as mere omission or inactivity. There was an act of battery which at its inception was not criminal because there was no element of intention, but which became criminal from the moment, the intention was formed to produce the apprehension which flowed from the continuous act of being on the complainant’s foot.
Battery Must Be Intentional, Reckless,
