Application by ATCO Gas Australia Pty Ltd

The case involved ATCO Gas Australia Pty Ltd, which sought leave to review a decision made by the Economic Regulation Authority (ERA) regarding a gas distribution access arrangement. The dispute centred around the ERA's decision to approve a revised access arrangement drafted by itself, rather than the arrangement proposed by ATCO. This decision was made under the National Gas Law (NGL) and related to the National Gas Access (WA) Act 2009. The Australian Competition Tribunal was tasked with determining whether ATCO could proceed with its application for leave to review the ERA's decision, and if so, whether the application met the criteria for such leave as outlined in section 248 of the NGL. Specifically, the Tribunal had to assess whether there was a serious issue to be heard and determined, and whether the asserted grounds of review, if substantiated, would likely result in a materially preferable decision in line with the National Gas Objective (NGO).

The primary legal issues before the Tribunal included whether ATCO's application was made within the stipulated time limit, whether ATCO qualified as an 'affected or interested person or body' under the NGL, and whether the asserted grounds for review were sufficient to warrant a review. Additionally, the Tribunal needed to determine if the ERA's decision was subject to review and if the grounds for review, if upheld, would result in a materially preferable decision aligned with the NGO. The Tribunal also examined the relevance and weight of the affidavits provided by ATCO in support of their application.

The Tribunal found that ATCO's application for leave was made within the 15 business day limit specified by the NGL. ATCO was recognised as an 'affected or interested person or body', and the ERA's decision was deemed a designated reviewable regulatory decision. The Tribunal concluded that the application met the criteria for leave as per section 248 of the NGL, as it identified a serious issue that, if resolved in ATCO's favour, could result in a materially preferable decision in line with the NGO. The Tribunal granted ATCO leave to review the ERA's decision, allowing the application to proceed to the review stage.

The final orders of the Tribunal were that ATCO was granted leave to review the ERA's decision regarding the gas distribution access arrangement, and the application for review was allowed to proceed. The Tribunal's decision provided clarity on the criteria for leave to review under the NGL and confirmed the process for addressing disputes concerning regulatory decisions related to gas distribution access arrangements.
