10 Prior to considering the parties' evidence and submissions in detail, I should note that while the Councils seek any documents which record any assessment, advice or recommendation relating to the economic impacts of the East West Project, it is apparent from the Grounds, and the evidence relied upon by the Councils, that the primary target of the discovery application appears to be the business case. This document has been referred to by Ministers of the State in public pronouncements regarding the East West Project, but has not been made public. The business case has been the subject of Freedom of Information applications and reviews before the Victorian Civil and Administrative Tribunal ('VCAT') whereby VCAT has upheld the decisions of the relevant authorities to withhold disclosure of the business case from interested parties. As the business case was not before the Court on this application, it is not possible to conclusively determine whether the business case contains the type of economic and financial information which the Councils contend should have been considered by the Minister when making the approval decision. However, from reviewing a document titled 'East West Link Stage One: Executive Summary: Short Form Business Case: Information for Infrastructure Australia',[1] and in particular, the contents of page 7 of that document, under the heading 'Cost benefit analysis', it seems to me to be tolerably clear that the contents of the business case would fall within that description, and would be quite likely to contain detailed information regarding the economic and financial aspects and impacts of the East West Project. The Minister, in the Reasons, stated that he 'did not rely upon a business case'. However, no evidence was advanced on behalf of the Minister and the State that the Minister did not have, or never had the business case in his possession, or that he has never reviewed or considered the business case for the purpose of making the approval decision, or any other purpose. Rather, they resist the application on the basis that the Councils have not established the necessary facts to ground a discovery application, and that in any event, my discretion to order discovery, which is substantially constrained by the judgment of the Court of Appeal in East Melbourne Group Inc v Minister for Planning and Anor,[2] ('East Melbourne case') should be exercised against the Councils on the basis that the discovery application is a mere fishing expedition.
