Peacock v The King

The appellant, a medical practitioner, was convicted of the murder of Mary Davies in the Supreme Court of Victoria. The Crown's case alleged that the appellant performed an illegal operation to procure an abortion on the deceased, who subsequently died from the effects of the procedure. The appellant was further accused of secretly disposing of her body. The evidence presented by the Crown was largely circumstantial, relying on the testimony of an individual named Poke, who claimed to have had conversations with the appellant regarding the deceased's condition, death, and the disposal of her body and belongings.

The legal issues before the High Court included whether the evidence was sufficient to prove the corpus delicti, specifically the fact of death, and whether the appellant caused the death. The Court was also required to consider the impact of the trial judge's failure to caution the jury against convicting on the uncorroborated evidence of an accomplice, and the correctness of the judge's directions regarding a statement made by the appellant to the jury. Additionally, the admissibility of certain evidence tendered by the Crown was in question.

The High Court, by majority, held that the fact of death and the fact that the prisoner caused the death could be proven by circumstantial evidence. However, a majority of the Court found that the trial judge's direction to the jury concerning the appellant's unsworn statement was erroneous and invalidated the conviction. The Court also considered the practice regarding warnings about accomplice testimony, with differing views expressed on whether the omission constituted a legal error or a matter of practice. The majority ultimately determined that a new trial should be granted.
