Grattan v The Queen

The High Court of Australia considered the appeal of Grattan against the conviction entered against him in the Supreme Court of New South Wales. The dispute concerned the admissibility of certain evidence during Grattan's trial for murder.

The central legal issue before the High Court was whether the evidence of a confession made by Grattan to police, obtained after he had been cautioned, was admissible. This question involved an examination of the principles governing the admissibility of confessions, particularly where the confession is made after a caution has been given but before the accused has had an opportunity to seek legal advice.

The High Court held that the caution administered to Grattan was sufficient to render his subsequent confession admissible. The Court reasoned that the purpose of a caution is to inform an accused person of their rights, including the right to remain silent and the right to seek legal advice. Once a caution has been given, the onus shifts to the accused to seek legal advice if they wish to do so. The Court affirmed that a confession made after a proper caution, even if before legal advice is obtained, is not automatically rendered inadmissible. The appeal was dismissed.
