A clear distinction is seen in the definitions of an act and omission. When the actus reus, and mens rea of a crime exists – an act is an action that have caused harm to a person, or damage to property, while an omission is where an action that could have reduced or prevented the harm or damage is not taken when the person in under a duty.

This decision circumvented the issue of necessitating the mens rea and actus reus of battery to coincide; however, it led to the blurring of the distinction.
Similarly, in the case of R v Miller [1982], the Court of Appeal held that Miller’s accidental falling asleep with a lit cigarette and his movement to the next room was one continuous reckless act.

His consequent omission to put out the fire was said to amount to the actus reus of arson. As such, a distinction could have been drawn in Fagan if his act of driving the car onto the victim was perceived to
