the court may order that the period of limitation for the action be extended so that it expires at the end of 1 year after that date and thereupon, for the purposes of the action brought by the applicant in that court, the period of limitation is extended accordingly."
21 Section 31 confers a discretionary power, and in addition to satisfying the provisions of s 31(a) and (b), the plaintiff must show that it is in the interests of justice to extend time. The onus of satisfying the court that the discretion should be exercised in favour of the plaintiff, rests on the plaintiff - Brisbane South Regional Health Authority v Taylor (1996) 186 CLR 541; 139 ALR 1. Taylor involves the extension of time under these Queensland legislative provisions.
22 As previously stated on 4 November 2000 during the course of an inpatient visit by Professor Delbridge at the Mater Hospital, the plaintiff was informed by Professor Delbridge that her neck and thyroid looked as though they has been "radiation affected" but he would need to wait to get pathology back in a few days. It is not disputed that the 4 December 2000 was the first occasion on which the plaintiff had been informed that there was a direct connection between the condition from which she was then suffering and her exposure to radiation suffered in the course of her employment with Central Coast Area Health Service, Darling Downs Health Authority and Hunter Area Health Service [Plaintiff's aff para 40]. I am satisfied that in November 2000 the plaintiff became aware of a material fact of a decisive factor. The plaintiff became aware that the occurrence of negligence caused her personal injury. The application was made on 14 September 2001. The plaintiff acquired this knowledge within the requisite time frame referred to in s 31(2). She has passed the threshold provision.
23 The more critical issue is that of prejudice caused by delay. In Taylor McHugh J referred to the effects of delay in the now often quoted passage which states:
"The effect of delay on the quality of justice is no doubt one of the most important influences motivating a legislature to enact limitation periods for commencing actions. But it is not the only one. Courts and commentators have perceived four broad rationales for the enactment of limitation periods. First, as time goes by, relevant evidence is likely to be lost. Second, it is oppressive, even "cruel", to a defendant to allow an action to be brought long after the circumstances which gave rise to it have passed. Third, people should be able to arrange their affairs and utilise their resources on the basis that claims can no longer be made against them. Insurers, public institutions and businesses, particularly limited liability companies, have a significant interest in knowing that they have no liabilities beyond a definite period."
24 and;
"Legislatures enact limitation periods because they make a judgment, inter alia, that the chance of an unfair trial occurring after the limitation period has expired is sufficiently great to require the termination of the plaintiff's right of action at the end of that period. When a defendant is able to prove that he or she will not now be able to fairly defend him or herself or that there is a significant chance that this is so, the case is no longer one of presumptive prejudice. The defendant has then proved what the legislature merely presumed would be the case. Even on the hypothesis of presumptive prejudice, the legislature perceives that society is best served by barring the plaintiff's action. When actual prejudice of a significant kind is shown, it is hard to conclude that the legislature intended that the extension provision should trump the limitation period.
In such a situation, actual injustice to one party must occur. It seems more in accord with the legislative policy underlying limitation periods that the plaintiff's lost right should not be revived than that the defendant should have a spent liability reimposed upon it."
25 and;
The discretion to extend should therefore be seen as requiring the applicant to show that his or her case is a justifiable exception to the rule that the welfare of the State is best served by the limitation period in question. Accordingly, when an applicant seeks an extension of time to commence an action after a limitation period has expired, he or she has the positive burden of demonstrating that the justice of the case requires an extension."
