R v Impey

The respondents were convicted of various drug offences, including supplying a commercial quantity of a prohibited drug, namely tetrahydrocannabinol (THC). The case was heard in the Supreme Court of Victoria. The respondents appealed against their convictions and sentences, arguing that the quantity of THC involved did not constitute a commercial quantity and that their use of the drug was for medicinal purposes.

The primary legal issues before the court were whether the quantity of THC supplied constituted a commercial quantity and whether the respondents' use of the drug was for medicinal purposes. The court also had to consider whether the respondents were guilty of dealing with the proceeds of crime.

The court held that the quantity of THC supplied did constitute a commercial quantity, and that the respondents' medicinal use defence was not applicable in this context. The court found that the respondents had knowingly participated in the supply of a commercial quantity of a prohibited drug. Furthermore, the court held that the respondents were guilty of dealing with the proceeds of crime, as they had financial gain from the drug supply activities.

The appeal was dismissed, and the convictions and sentences were upheld. The court ordered that the respondents be imprisoned for various terms, with the longest being 12 years, and that they be subject to other conditions as specified in the judgment.
