The respondent father applied for a mistrial in a child protection proceeding, alleging numerous procedural irregularities and disclosure failures by the applicant agency.

The Office of the Children's Lawyer joined the application, while other parties opposed it.

The court reviewed the established test for mistrial, emphasizing it as a measure of last resort for fatally wounded trial processes.

While acknowledging the applicant's chaotic and haphazard disclosure practices and inefficient trial management, the court found that the cumulative effect of the issues did not fatally compromise trial fairness.

The court ordered certain evidence struck and mandated further disclosure from the applicant, but ultimately dismissed the mistrial application, prioritizing the child's best interests and avoiding further delay.

The applicant child protection agency sought to qualify an expert in child maltreatment.

The court conducted a voir dire to determine the admissibility of the expert's opinion evidence.

The court found that "child maltreatment" as a general field of scientific inquiry lacked threshold reliability as a novel science, as there was no evidence of tested theories/techniques, peer review of the general discipline, or established standards for information quality.

Furthermore, the court determined that the expert was engaged for litigation purposes, not as a "participation expert" and thus failed to comply with Rule 20.2(2) of the Family Law Rules.

Consequently, the expert was not qualified, and his report was not admitted, as the risks of admitting unreliable evidence outweighed any benefit.

This corrigendum corrects a clerical error in the reasons for judgment released on June 30, 2016.

Specifically, the date for fixing spousal support arrears in paragraph 2 of the final order is corrected from "November 5, 2011" to "November 5, 2015", thereby fixing the spousal support arrears at $24,187 as of the corrected date.
