Godfrey v New South Wales (No 1)

Godfrey v New South Wales (No 1) involved the plaintiff, Godfrey, bringing an action against the State of New South Wales for injuries sustained during a police operation. The dispute centred on the admissibility and weight of expert opinion evidence provided by the plaintiff's expert witness, which the defendant argued should be excluded due to the witness's lack of relevant experience. The case was heard by the Supreme Court of New South Wales.

The legal issues before the court were whether the plaintiff's expert witness, despite lacking specific experience in the field, could provide admissible expert opinion evidence, and if so, the extent to which the jury should consider such evidence. The court needed to balance the weight and admissibility of the expert opinion against the defendant's argument that the witness's lack of direct experience rendered the evidence unreliable.

In delivering the judgment, the court held that while the lack of specific experience might diminish the weight of the expert's opinion, it did not necessarily render it inadmissible. The court found that the expert's general experience and knowledge in related areas provided a sufficient basis for the opinion, and it was for the jury to determine the appropriate weight to give to the evidence. The court also noted that the expert's opinion, even if somewhat diminished, could still contribute to the jury's understanding of the issues and was not to be entirely disregarded.

The final orders of the court did not directly address the admissibility or weight of the evidence, as it was ultimately left to the jury to consider in their deliberations. However, the court's ruling clarified the parameters within which the jury should evaluate the expert opinion evidence, ensuring that the expert's lack of direct experience was properly accounted for in the assessment of the evidence's credibility and relevance.
