[5] The representations case concerns what happened at a meeting or meetings attended, on the defendant's side, by Mr Harrington, Mr Pisani and Mr Mares. The issues of what was said at these meetings are likely to require findings as to the reliability, if not the credibility, of these witnesses. They are also likely to be relevant witnesses in the defendant's case for issues not proposed for the preliminary trial, more specifically issues involving the alleged breach or breaches of contract and issues of causation of loss. Some of the plaintiff's representations case is admitted, in that, for example, there is an admission that the defendant represented to the plaintiff that if the parties were able to agree on the terms of the proposed sale of the equipment, the defendant would be able to have the sale equipment delivered to the mine site and commissioned by a certain time. The defendant pleads that it had reasonable grounds for making that representation and Mr Mares will be a relevant witness in that respect. The same applies to Mr Pesani. Mr Mares would give evidence in the proposed second hearing as to what occurred on site, relating to questions of causation. Then there are issues concerning the maintenance contract and whether, as the plaintiff alleges, it was an implied term of that contract that the defendant would maintain the equipment so as to achieve what were described as "availability targets". Mr Mares would be a relevant witness on this question.
