Pediatrician permitted to testify as a participant expert in child protection trial with circumscribed scope.
In a child protection trial, the Children's Aid Society sought to qualify a pediatrician as a participant expert.
The Office of the Children's Lawyer and the parents opposed the qualification, arguing the pediatrician was engaged for litigation and his methodology was flawed.
The court applied the White Burgess framework and Rule 20.2 of the Family Law Rules, concluding the pediatrician could testify as a participant expert because his opinions were formed during his involvement as a treating pediatrician, not for litigation.
The court circumscribed the scope of his permissible evidence to his observations, diagnosis, treatment, and prognosis of the children.
