Chapman v R

In the case of Chapman v R, the appellant, Chapman, appealed against a conviction for supplying a prohibited drug. The appeal arose from a decision of the Court of Appeal of the Supreme Court of Queensland. Chapman argued that the indictment was defective due to duplicity, as it encompassed alternate factual bases of liability. The primary issue before the court was whether the indictment contained two or more distinct charges in a single count, rendering it fundamentally flawed.

The court examined whether the charge of supplying a prohibited drug involved factually alternative cases available. The court considered the principles established in previous cases, such as R v. Johnson, where the High Court held that an indictment is not necessarily defective merely because it alleges facts that are alternative. The court also looked at whether the analogy with manslaughter applied, where the court found that the requirement for distinctness in charges of manslaughter and murder was not strictly applied.

The court held that the indictment was not fundamentally flawed due to duplicity. The court found that the charge of supplying a prohibited drug did not involve factually alternative cases, as the essential elements of the offence were not in dispute. The court concluded that the indictment was valid, and Chapman's appeal was dismissed. The court of appeal affirmed the conviction, and Chapman's appeal to the High Court was subsequently dismissed.
