The Director of Investigation and Research sought to intervene in a tariff application before the Board of Commissioners of Public Utilities for New Brunswick.
The Board refused permission, finding the Director lacked statutory authority to intervene.
The Court of Queen's Bench dismissed an application for judicial review, but the Court of Appeal allowed it.
The Supreme Court of Canada allowed the appeal and restored the Board's decision, relying on its concurrent judgment in a companion case involving Newfoundland Telephone Co.
