What is the role of a tribunal at the "high end" of the spectrum?

Bell Canada appears to acknowledge a form of tribunal to which the characterization of administrative tribunals in Ocean Port simply does not apply. In Ocean Port, in the context of a tribunal constituted to adjudicate the policy laden question of whether, and to what degree, a licence holder had breached the conditions of a government administered privilege, the court used broad language that does not really describe the function of tribunals at the “high end” of the spectrum. The decision to grant or withhold a government licence or privilege, or the adjudication of a breach of such a licence or privilege, is a markedly different function from what is required of a tribunal constituted to try, as between citizens, issues arising in relation to a statute governing a realm of private law. As I have observed, the statute itself may reflect government policy in its terms, but adjudication as between private individuals is a judicial function, a point made in another fashion in British Columbia v. Imperial Tobacco.
