Keller v R [2006] NSWCCA 204

Keller v R [2006] NSWCCA 204

The expert opinion evidence of Federal Agent Ian Robert Smith should have been excluded as it was not sufficiently based on specialised knowledge and the reasoning process was not adequately exposed. Additionally, the trial judge failed to properly caution the jury about how to assess this opinion evidence. These errors warranted quashing the conviction and sentence, and a new trial was ordered.
