A decision by the National Consumer Tribunal to grant leave to refer a complaint directly to it under section 141(1)(b) of the National Credit Act is not a "decision" made in "a hearing" as contemplated in section 148(2)(b) and is therefore not appealable to the High Court. Section 141(1)(b) confers on the Tribunal a wide, largely unfettered discretion to permit direct referral and does not require a formal application or public hearing. No formal test applies; the Tribunal should simply consider whether the complaint deserves its attention, having regard to various factors which may include prospects of success, importance of the issue, public interest, allocation of resources, the complainant's interest in the relief sought, and the fact that the Regulator did not consider it merited a hearing. Allowing appeals against such rulings would be contrary to the NCA's purpose of providing quick, informal, and cost-effective resolution of complaints.
