Cleanaway Waste Management Ltd. announced decision of the High Court of Australia to dismiss the special leave application that sought to challenge the legal validity of the works approval to extend Cleanaway's Melbourne Regional Landfill in Ravenhall, Victoria (MRL). In June 2017, the Planning Minister for Victoria issued planning approval for the extension of landfilling operations at MRL until 2046, or such earlier time as the landfill's capacity is exhausted. This planning approval remains on foot. Both planning and works approvals are required to enable ongoing operations. The High Court on 20 May 2021, confirmed the validity of the works approval, first granted to Cleanaway by the Environment Protection Authority Victoria (EPA) in March 2017 and, following a review application, granted by the Victorian Civil and Administrative Tribunal, in June 2019. Cleanaway has also successfully defended challenges to the decision to grant the works approval in the Victorian Supreme Court and the Court of Appeal. The High Court decision on 20 May 2021, finally resolves this matter, securing critical airspace for managing Melbourne's residual waste streams into the future.
