28 Second, permitting five or six sample members to have their damages claims assessed may well lead to an unacceptable lengthening of the trial. Notwithstanding their enthusiasm for the damages assessment to take place in the course of the trial, counsel were unable to provide an estimate as to the additional length of time that may be occupied in determining the quantum of the claims. Indeed, the expression "how long is a piece of rope" may be the answer. It will not be just a question of calling the sample member to establish his or her loss. In the case of a personal injuries claim, supporting evidence will undoubtedly come from a number of medical practitioners. Actuaries and accountants may play a part, as may friends, relatives and employers. In the property damage cases, the same ballooning out is possible. There may be agricultural experts, agronomists and a number of lay witnesses to give evidence as to a particular form of loss. Claims for pure economic loss will involve, one could surmise at least, evidence from a forensic accountant, as well as body of lay evidence. This is to say nothing of the fact that such evidence in any of these cases may be hotly in dispute and contradictory evidence may be called. In my opinion, the length of time that will be occupied by the assessment of damages of sample group members is totally open ended, notwithstanding the reassuring assertions of counsel to present the issues in a succinct fashion.
