(1985) 66 A.L.R. 299 at pp.314-5), the practical impact of the
grant of interim relief at this stage should be considered. In
thas connection, it 1s important first to estimate the period
over which the "interim" restraint would operate. It would
seem probable that, if now granted, an interlocutory
injunction (or its equivalent in the form of stays in the
event of appeal) could remain in force for as long as two
years. The present litigation, on any view, is complex. At
the heart of 1t lies an investigation of two markets - the New
South Wales hotel and wholesale beer markets. It is plain
that, even if expedited, the final hearing could not take
place in less than three months from now. A realistic
estimate of the time required by all parties to prepare
properly for a final hearing, bearing in mind that, most, 1f
not all, parties will probably call expert evidence, is at
least six months. Moreover, it may be expected that the
final hearing would occupy at least 4 weeks. The trial judge
would probably reserve his decision. During all this time,
the interim injunction now sought would run. Let it then be
assumed that the trial judge were to dismiss the claim for
final relief and to dissolve the interim injunction. It is
likely that CUB (NSW) would then appeal to a Full Court. The
appeal could probably not be ready to be heard within a
further six months. It is likely that, pending the hearing of
the appeal, CUB (NSW) would seek a stay of the order
dissolving the interim injunction. If the appeal failed, an
application for leave to appeal to the High Court is likely,
together with an application to stay further the order
