Martyn v Cooper

The case of Martyn v Cooper involved the appellant, Martyn, who was convicted of an offence under the Road Transport (Alcohol and Drugs) Act 1977 (ACT) for refusing to permit a blood sample to be taken. The conviction arose after Martyn was required to give permission to have his blood taken by a doctor following a police officer's advice. Martyn appealed the conviction on the grounds that the doctor lacked the authority to require him to permit the blood sample, as the power to require such a sample was with the police officer alone.

The primary legal issue before the court was whether the doctor had the lawful authority to require Martyn to permit a blood sample to be taken. The court needed to determine whether the power to require a blood sample was solely with the police officer or whether there was an implied power for the doctor to make such a requirement. This issue hinged on the interpretation of the relevant statutory provisions and the role of the doctor in the context of the police officer's authority.

The court found that the statutory framework did not confer an implied power on the doctor to require a blood sample. The authority to require such a sample was explicitly vested in the police officer, and there was no provision that allowed for the delegation of this power to the doctor. The court held that the doctor's request, made without a requirement from the police officer, was not lawful. Consequently, the court set aside the conviction and sentence and dismissed the charge against the appellant.

In summary, the appeal was allowed, and Martyn's conviction and sentence were set aside. The charge of refusing to permit a blood sample to be taken was dismissed due to the doctor's lack of lawful authority to make such a requirement.
