Tan Seng Kiah v The Queen

The appeal concerned the admissibility of a record of interview in criminal proceedings. The appellant, Tan Seng Kiah, challenged his conviction and sentence, arguing that the interview was obtained in breach of Part 1C of the *Crimes Act 1914* (Cth). A key point of contention was whether the appellant was unlawfully detained beyond the prescribed four-hour period for investigation, or if the intervening "down time" rendered the detention lawful.

The Court of Appeal was required to determine two primary legal issues. Firstly, whether the record of interview was admissible, considering potential breaches of statutory rights under the *Crimes Act 1914*. Secondly, the court had to consider whether the denial of the appellant's rights, specifically the right to legal or consular access and the right to an interpreter, created such unfairness as to warrant the exclusion of the confessional material, even if it was not involuntary or unreliable, on public policy grounds.

The court reasoned that the admissibility of the interview depended on whether the detention period complied with the *Crimes Act 1914*. It considered the concept of "down time" in relation to the four-hour limit and whether an application to a magistrate for an extension was necessary. Furthermore, the court examined the interplay between the right to legal or consular access and the right to an interpreter, assessing whether the latter subsumed the former or existed as a separate right. The court applied principles relating to the exercise of discretion to exclude unlawfully obtained evidence and considered public policy implications.
