The appeal court said that in criminal cases where it is necessary for the prosecution to prove intention, they must always do just that. Intention can never be presumed, subject to being disproved by the person accused. Hence the phrase that everyone is ‘innocent unless proven guilty’.
Doesn't the bolded clause contradict the other sentences? The first sentence connotes that intention is subject to being proved by the prosecutor. Since the accused person is presumed guilty, he/she has to prove or disprove nothing?
