The binding legal principles established are: (1) When a party fails to comply with a Rule 35(12) notice, the party seeking production must follow the procedure in Uniform Rule 30A, which requires giving 10 days' notice of intention to apply for compliance and then making application to court if there is no compliance; (2) In applications to compel document production, the court exercises a general discretion to balance the conflicting interests of the parties, rather than applying a rigid onus; (3) In exercising this discretion, the court must not fetter its discretion by adopting a predisposition either for or against granting production; (4) In all matters concerning children, including litigation affecting them, their best interests under section 28(2) of the Constitution are of paramount importance and must be accorded adequate weight in the balancing exercise; (5) Children have constitutional and statutory rights to participate in proceedings affecting them, including through representatives acting in their interests or in the public interest; (6) Group representation of children's interests through an organization like the CCL, using confidential consultations and collective presentation of views, is an appropriate form of participation that protects children from potential victimization; (7) Confidentiality undertakings given to children to facilitate their participation in litigation may outweigh a party's interest in document discovery where the party seeking discovery has not demonstrated that its interests outweigh the children's interests in confidentiality.
