Energy Efficiency (Cost of Living) Improvement Amendment Act 2015 (ACT)

The parties involved in the case were the Australian Capital Territory and various retailers and approved abatement providers affected by the Energy Efficiency (Cost of Living) Improvement Amendment Act 2015. The dispute centred around the interpretation and application of certain provisions within the Act, specifically those related to the definition of "emissions multiplier" and "tier 1 NERL retailer," and the transition from the repealed section 22(3) to the new provisions. The case was heard in the Australian Capital Territory Supreme Court.

The primary legal issues the court had to resolve were the correct interpretation of the terms "emissions multiplier" and "tier 1 NERL retailer" as defined in the amended Act, and the transitional provisions that applied to compliance periods ending before the commencement of the new legislation. The court also had to determine the applicability of the repealed section 22(3) to compliance periods before 1 January 2016, and the implications of the new section 55A in relation to penalties for non-compliance and the expiry of certain parts of the Act.

The court examined the legislative language and context to interpret the new definitions and transitional provisions. It found that the term "emissions multiplier" should replace "emissions factor" as per the legislative amendments. The court also clarified that a "tier 1 NERL retailer" is one that had at least 5,000 customers in the ACT and sold at least 500,000 MWh of electricity during the previous compliance period. Regarding the transitional provisions, the court held that the repealed section 22(3) continued to apply to net shortfalls in compliance periods ending before 1 January 2016. Additionally, the court noted that penalties for non-compliance under the new section 55A would apply from the commencement day of section 18 of the Act, and that part 15 of the Act would expire one year after the commencement day.

The final orders of the court confirmed the interpretation of the terms and transitional provisions as outlined in the judgment, providing clarity for the parties involved in compliance with the amended Act.
