R v Jacobs (No 6)

The case involved a defendant, Jacobs, who was on trial for a serious criminal offence. The prosecution sought to introduce evidence of unfired cartridges found in Jacobs' home, which were of the same calibre and make as the ammunition used in the crime. The cartridges were discovered while Jacobs was hospitalised, not at the time of his arrest or during a search of his home. The matter was heard in the Supreme Court of Victoria. The court had to determine whether the evidence of the unfired cartridges was relevant and whether its probative value outweighed any potential for unfair prejudice to the defendant.

The court considered the relevance of the evidence, noting that the cartridges' similarity to those used in the crime could support an inference that Jacobs had access to ammunition of the same type. The court acknowledged the potential prejudicial effect of such evidence, given it could suggest a propensity towards violence or involvement in criminal activity. However, the court found that the probative value of the evidence, in establishing a link between Jacobs and the ammunition used in the crime, outweighed the prejudicial effect. The similarity in calibre and make was deemed significant enough to support a connection between Jacobs and the ammunition, thus justifying its admission.

In reaching its decision, the court balanced the probative value of the evidence against the risk of unfair prejudice. It concluded that the evidence was relevant and that its probative value was not substantially outweighed by the danger of unfair prejudice. Consequently, the evidence was admissible. The court allowed the prosecution to present the evidence of the unfired cartridges, finding it a permissible link in the chain of reasoning for the jury to consider. The decision underscored the importance of considering both the probative value and potential prejudice of evidence when making admissibility decisions.
