DPP v Mastwyk

The case of the Director of Public Prosecutions v Mastwyk involved a defendant who was charged with refusing to comply with a police officer's requirement to accompany them for a breath test. The defendant argued that the requirement to accompany the officer to the police van for the breath test was unreasonable and amounted to an unlawful detention. The matter was appealed to the Magistrates' Court of Victoria under section 92(1) of the Magistrates’ Court Act 1989 (Vic). The central issues before the court were whether the requirement to accompany a police officer for a breath test must be reasonable, and whether the use of the rear compartment of a police van as a means of transport constituted imprisonment, rendering the requirement invalid.

The court considered the statutory framework and previous case law on the matter. The court noted that the requirement for a person to accompany a police officer for a breath test is a reasonable requirement under the Road Safety Act 1986 (Vic), and that the use of the rear compartment of a police van for this purpose does not constitute imprisonment. The court held that the requirement to accompany the police officer was reasonable and that the defendant's argument that this requirement amounted to unlawful detention was not valid. The court found that the requirement did not breach any statutory provisions and did not amount to an unlawful arrest or detention.

In light of the above, the court dismissed the defendant's appeal and upheld the charge under section 49(1)(e) of the Road Safety Act 1986 (Vic). The court's decision emphasised that the requirement for a person to accompany a police officer for a breath test is a reasonable one, and that the use of the rear compartment of a police van for this purpose does not constitute imprisonment. The court's decision provides clarity on the interpretation of the statutory provisions and the requirements for a breath test under the Road Safety Act 1986 (Vic).
