The execution of a police officer's duty under s 158 of the Police Administration Act (NT) does not end upon the completion of an arrest. Resistance to police during post-arrest conveyance to a police station is capable of constituting the offence of resisting a member in the execution of his duty. Hallion v Samuels (1978) 17 SASR 558 does not stand for the broader proposition that post-arrest conduct can never constitute resisting police in the execution of duty; it only decided that on a charge specifically framed as resisting arrest, evidence of post-arrest conduct was irrelevant.
