R v Singh (No 6)

In the case of R v Singh (No 6), the defendant, Singh, was facing criminal charges in the Supreme Court of New South Wales. The primary dispute was whether expert opinion evidence should be excluded under section 79 of the Evidence Act 1995 (NSW). The court was tasked with determining if the expert opinion was based on facts that were within the expert’s area of specialised knowledge and whether the evidence was ultimately admissible. The expert in question was asked to provide an opinion based on a series of facts that were central to the prosecution's case.

The court was required to assess whether the expert's opinion was reliable and relevant, considering the foundational facts upon which the opinion was based. Specifically, the court needed to determine if these facts fell within the expert's area of specialised knowledge, as required by the statutory provisions. The central issue was whether the expert's opinion could be considered reliable and relevant if the foundational facts were not within the expert's area of expertise.

The court concluded that the expert's opinion was not admissible because it was based on facts that were outside the expert's area of specialised knowledge. The foundational facts were not within the scope of the expert's expertise, and therefore, the opinion could not be deemed reliable or relevant. The court held that the expert's opinion did not meet the threshold requirements set by section 79 of the Evidence Act 1995 (NSW). Consequently, the evidence was excluded from being presented to the jury.

The final orders of the court were that the expert opinion evidence was inadmissible and could not be presented to the jury in the case of R v Singh (No 6). This decision underscores the importance of ensuring that expert opinions are based on facts that are within the expert's area of specialised knowledge, as per the statutory requirements.
