R v Martin (No 5) [2017] NSWSC 1297

R v Martin (No 5) [2017] NSWSC 1297

The opinion that a Samurai type sword could have caused the injuries was plainly relevant to the issues in the trial. Although the circumstances in which the amended opinion was produced were troubling and highly relevant to credibility and weight, those deficiencies could be exposed before the jury and addressed by directions and warnings. The evidence was not shown to be unfairly prejudicial, misleading or confusing so as to warrant exclusion under s 135.
