Fagan v Metropolitan Police Commissioner (1969) established that an unintentional act, such as a car driven onto a policeman's foot, can become an assault if there is a deliberate failure to remove the vehicle, thus combining actus reus (the act) and mens rea (the intent).
Continuing Act Doctrine: The court ruled that an act, such as driving a car onto someone’s foot, can be considered ongoing until the offending party removes the vehicle, thus allowing the mens rea to be formed during the act.
