It is clear that the making of a requirement is an essential ingredient of the offence with which the appellant was charged. The authorities on the requirement to furnish a sample of breath, also contained in section 55(1), are equally applicable to the requirement to accompany a member of the police force to a police station. See Scott v Dunstone[1963] VicRp 77; [1963] VR 579 at 581-2 (Sholl J); Walker v DPP(1993) 17 MVR 194 at 195 (Fullagar J, with whom Brooking and McDonald JJ agreed). And the point is made specifically in relation to the offence in issue here in DPP v Foster[1999] VSCA 73 at [15] by Winneke P, with whom Ormiston and Batt JJA agreed.
