The appellant appealed an arbitrator's award that determined it was not in the best interests of the parties' two children to be vaccinated.

The Superior Court of Justice allowed the appeal, finding the arbitrator erred in his gatekeeping function by qualifying the respondent's experts, whose evidence on vaccine safety was unreliable and outside their expertise.

The arbitrator also erred by failing to admit government immunization guides under the public documents exception to the hearsay rule.

Having excluded the respondent's expert evidence and admitted the public documents and fresh expert evidence, the court found that the children's best interests required vaccination.

The appellant was granted sole decision-making responsibility for the children's vaccinations, and the respondent was ordered not to tell the children that vaccines are unsafe.

The appellant father and respondent mother both brought motions to introduce fresh evidence in an appeal from an arbitrator's decision declining to order their children be vaccinated.

The court applied a relaxed Palmer test, given the case involved the best interests of children.

The court admitted the father's fresh expert evidence regarding vaccine safety and the mother's genetic variation, as well as evidence challenging the credibility of one of the mother's experts.

The court also admitted the mother's fresh evidence from the children's family doctor regarding their current health and the psychological impact of the litigation.

A temporary publication ban on the children's health information was made permanent.
