Before charging a prisoner, a police officer must have ‘an honest belief in the guilt of the accused based upon a full conviction, founded upon reasonable grounds, of the existence of a state of circumstances, which, assuming them to be true, would reasonably lead any ordinary prudent and cautious man, placed in the position of the accuser to the conclusion that the person was probably guilty of the crime imputed.’
Once a plaintiff has established his imprisonment, the onus then lies on the defendant to ‘plead and prove affirmatively the existence of reasonable cause’.
