Negligence – Causation. While it was natural to suspect a link between the significant overdose of pancuronium and the claimant's severe neurological injury, sustained at birth, the evidence did not establish the necessary causal connection between the two. Overall, the claimant's neurological injury was explained by his prematurity and perinatal course. Accordingly, the Queen's Bench Division ruled that causation had not been established and the claim against the defendant NHS Trust was dismissed.
