A child protection agency sought to introduce expert psychiatric evidence regarding the impact of parental substance abuse on child parenting capacity.
The court conducted a voir dire to determine the admissibility of the expert evidence.
The respondent parents opposed the evidence on grounds of relevance, necessity, expert qualification, procedural non-compliance, and prejudicial effect.
The court excluded the evidence, finding it lacked relevance and necessity, the expert was not properly qualified in the specific area of substance abuse and parenting, and the probative value was substantially outweighed by prejudicial effect, particularly given inadequate notice and the risk of case delay contrary to the child's best interests.
