R v Qaumi & Ors (No 46) [2016] NSWSC 938

R v Qaumi & Ors (No 46) [2016] NSWSC 938

The reference to lead in Dr Collins' certificate was inadmissible because no basis or relevant expertise was shown for that opinion. Dr Gunja's evidence was admissible because he had forensic toxicology expertise, made a thorough assessment of possible lead sources, excluded other explanations, and his conclusion that embedded pellets caused H's elevated blood lead levels was not circular. The evidence about future fertility, pregnancy and toxicity risks had high probative value on whether H's injuries constituted grievous bodily harm and was not misleading or unfairly prejudicial.

Procedural Posture

Criminal Trial / Procedural Ruling on Objection to Expert Medical Evidence

Legal Issues

  1. 1 ["Whether evidence that pellets lodged in H's body contained lead and caused elevated blood lead levels was inadmissible as speculative or circular reasoning." 'Whether Dr Collins had a sufficient basis or expertise to state that H had lead pellets behind L5.' "Whether Dr Gunja was qualified to give opinions that elevated lead levels were caused by shotgun pellets remaining in H's body." 'Whether evidence about future risks of hypertension, anaemia, neurocognitive impairment, renal disease, infertility and foetal neurodevelopment impairment was unfairly prejudicial under s 137 of the Evidence Act 1995 (NSW) or misleading under s 135.']

Dr Gunja's evidence was admissible because he had forensic toxicology expertise, made a thorough assessment of possible lead sources, excluded other explanations, and his conclusion that embedded pellets caused H's elevated blood lead levels was not circular. The evidence about future fertility, pregnancy and toxicity risks had high probative value on whether H's injuries constituted grievous bodily harm and was not misleading or unfairly prejudicial.
