This ruling addresses the admissibility of evidence in a first-degree murder trial.
The court considered the admissibility of crime scene and autopsy photographs, evidence of the accused's knife collection, and proposed expert psychiatric testimony.
The court admitted several panoramic and autopsy photographs, requiring editing for some to minimize prejudice, while excluding others deemed repetitive or overly graphic.
Evidence that the accused possessed a knife collection was deemed admissible through police testimony, but the physical knives or their photographs were excluded due to high prejudicial effect outweighing marginal probative value.
The proposed expert evidence from a forensic psychiatrist, intended to explain the accused's actions based on past trauma, was ruled inadmissible as it failed the necessity criterion, amounted to impermissible oath-helping, and encroached on the jury's function to assess intent and self-defence.
