6. The plaintiffs, on the other hand, do not wish to go through the process of discovery prior to having the question of liability determined. They submitted that discovery would be a lengthy and costly process involving many documents accumulated over many years. Most of the plaintiffs are farmers whose property suffered as a consequence of the fire. To establish their loss, they will need to establish the profitability of their farms so as to ground any claims. Not only would this involve the discovery of documents such as tax returns and books of account, it could involve discovery of all the source documents going back many years. It would not doubt be possible to undertake discovery in waves - that is to say to begin with tax returns and accounts and then only order the production of source documents if that proved necessary in a particular case. But even if the discovery process is undertaken in stages it will be onerous, time consuming and costly. What is more, it will undoubtedly delay the hearing of the action. It would take months for the one firm acting for 61 plaintiffs to prepare adequate discovery for each of them. In my view such a delay should, if at all possible, be avoided.
