Ingrassi v The Queen

Ingrassi appealed to the High Court of Australia against his conviction for armed robbery. The central dispute concerned the admissibility of evidence obtained through a police interview conducted after the appellant had been arrested and charged.

The High Court was required to determine whether the evidence obtained during the interview was admissible, specifically in light of the appellant's right to silence and the circumstances under which the interview was conducted. The court considered the application of the common law privilege against self-incrimination and the principles governing the admissibility of confessions.

McHugh and Hayne JJ, in their joint judgment, held that the evidence was inadmissible. They reasoned that the police had failed to adequately inform the appellant of his right to remain silent and had continued to question him after he had indicated a desire not to answer further questions. The court applied the principle that a confession obtained in circumstances where a suspect's right to silence has been infringed is generally inadmissible, as it would be unfair to admit such evidence. The appeal was allowed, and the conviction was quashed.
