Assault charges can arise out of any number of circumstances, such as an argument with a domestic partner, a dispute with a neighbour, or a fight outside a bar. The offence of assault is widely defined. It includes any circumstance where a person, without the consent of the other person, applies force intentionally to that person, directly or indirectly. It also includes certain situations where no actual force is applied. An assault occurs when a person attempts or threatens, by an act or a gesture, to apply force to another person, if he has, or causes that other person to believe upon reasonable grounds, that he has, present ability to effect his purpose.
