R v Martin (No 9)

In this case, the defendant, Martin, was charged with murder. The prosecution sought to introduce evidence that the width of the samurai sword used in the fatal attack was between 2.5 to 3.5 centimetres, despite the fact that the actual measurement of the sword was approximately 2.3 centimetres. The pathologist who gave evidence on behalf of the prosecution had assumed that the sword was 2.5 to 3.5 centimetres wide, but this assumption was later found to be incorrect. The issue before the court was whether the evidence of the sword’s width was relevant and admissible, despite the incorrect assumption made by the pathologist.

The court found that the evidence was relevant, as it was necessary to correct the erroneous assumption made by the pathologist. The court also found that the evidence was not prejudicial, as it was relevant to the case and did not have the potential to unfairly influence the jury against the defendant. The court held that the evidence was admissible to correct the erroneous assumption made by the pathologist. The court also held that the evidence was necessary to assist the jury in understanding the nature of the fatal wound and the weapon used in the attack.

In conclusion, the court found that the evidence of the sword’s width was admissible, as it was relevant and necessary to correct the erroneous assumption made by the pathologist. The court held that the evidence was not prejudicial and did not unfairly influence the jury against the defendant. The court found that the evidence was necessary to assist the jury in understanding the nature of the fatal wound and the weapon used in the attack. The final orders of the court were not provided in the text.
