On 18 November 1999 Duke Eastern Gas Pipeline Pty Ltd, DEI Eastern Gas Pipeline Pty Ltd and Duke Australia Operations Pty Ltd (Duke Operations) submitted an access undertaking covering access to the Eastern Gas Pipeline. In its draft decision and final decision the Commission decided that, due to the lack of information available to it, it was unable to determine that it would be appropriate to accept the undertaking. Consequently, it decided not to accept the undertaking. The Australian Competition and Consumer Commission administers gas access undertakings. See access undertakings on the ACCC website for more information.
