13 The proposed pleading makes allegations of fact against Marr, Hanson and Minshull which, if proved along with other necessary material facts, establish liability on their part. If there are any deficiencies in the pleading, and that is by no means certain, they are deficiencies in particulars. In a case of this nature the authorities make it clear that a plaintiff might reasonably be expected to be unable to give precise particulars of material facts sufficient to establish its cause of action by reason of the very nature of the transactions it is attempting to prove. The cases referred to above support such a position, as does the judgment of Drummond J in State of Queensland v Pioneer Concrete (Qld) Pty Ltd[4] referred to in Gunns Limited v Marr,[5] the first case in which the plaintiffs' claims were considered. A determination as to whether proofs offered by the plaintiffs in respect of the allegations they make against Marr, Hanson and Minshull (and, for that matter, Douglas as well) will permit the necessary inferences, must await a trial. It may be that after interlocutory processes are completed, the plaintiffs will be able to supplement the particulars of their claims already provided. However, whether or not this is so, the plaintiffs' pleading is satisfactory for its purpose and, subject to any other relevant considerations, should be permitted to go forward against Marr, Hanson, Minshull and Douglas.
