“Section 33(3) of LA 1980 requires the court, when exercising its discretion under section 33(1), to have regard to all the circumstances of the case but also directs the court to have regard to the five matters specified in subsections 33(3)(a)-(f). There are numerous reported cases in which the court has elaborated on the application of that statutory direction in the context of the particular facts of the case. In many of the cases the court has stated various principles of general application. The general principles may be summarised as follows. 1) Section 33 is not confined to a "residual class of cases". It is unfettered and requires the judge to look at the matter broadly: Donovan v Gwentoys Ltd[1990] 1 WLR 472 at 477E; Horton v Sadler[2006] UKHL 27 ,[2007] 1 AC307 , at [9] (approving the Court of Appeal judgments in Finch v Francis unrptd 21.7.1977); A v Hoare[2008] UKHL 6 ,[2008] 1 AC 844 , at [45], [49], [68] and [84]; Sayers v Lord Chelwood[2012] EWCA Civ 1715 [2013]1 WLR 1695, at [55]. 2) The matters specified in section 33(3) are not intended to place a fetter on the discretion given by section 33(1), as is made plain by the opening words "the court shall have regard to all the circumstances of the case", but to focus the attention of the court on matters which past experience has shown are likely to call for evaluation in the exercise of the discretion and must be taken into a consideration by the judge: Donovan at 477H-478A. 3) The essence of the proper exercise of the judicial discretion under section 33 is that the test is a balance of prejudice and the burden is on the claimant to show that his or her prejudice would outweigh that to the defendant: Donovan at 477E; Adams v Bracknell Forest Borough Council[2004] UKHL29,[2005] 1 AC 76 , at [55], approving observations in Robinson v St. Helens Metropolitan Borough Council [2003] PIQR P9 at [32] and [33]; McGhie v British Telecommunications plc[2005] EWCA Civ 48 , (2005) 149 SJLB 114, at [45]. Refusing to exercise the discretion in favour of a claimant who brings the claim outside the primary limitation period will necessarily prejudice the claimant, who thereby loses the chance of establishing the claim. 4) The burden on the claimant under section 33 is not necessarily a heavy one. How heavy or easy it is for the claimant to discharge the burden will depend on the facts of the particular case: Sayers at [55]. 5) Furthermore, while the ultimate burden is on a claimant to show that it would be inequitable to disapply the statute, the evidential burden of showing that the evidence adduced, or likely to be adduced, by the defendant is, or is likely to be, less cogent because of the delay is on the defendant: Burgin v Sheffield City Council[2015] EWCA Civ 482 at [23]. If relevant or potentially relevant documentation has been destroyed or lost by the defendant irresponsibly, that is a factor which may weigh against the defendant: Hammond v West Lancashire Health Authority[1998] Lloyd's Rep Med 146 . 6) The prospects of a fair trial are important: Hoare at [60]. The Limitation Acts are designed to protect defendants from the injustice of having to fight stale claims, especially when any witnesses the defendant might have been able to rely on are not available or have no recollection and there are no documents to assist the court in deciding what was done or not done and why: Donovan at 479A; Robinson at [32]; Adams at [55]. It is, therefore, particularly relevant whether, and to what extent, the defendant's ability to defend the claim has been prejudiced by the lapse of time because of the absence of relevant witnesses and documents: Robinson at [33]; Adams at [55]; Hoare at [50]. 7) Subject to considerations of proportionality (as outlined in (11) below), the defendant only deserves to have the obligation to pay due damages removed if the passage of time has significantly diminished the opportunity to defend the claim on liability or amount: Cain v Francis[2008] EWCA Civ 1451 ,[2009]QB 754, at [69]. 8) It is the period after the expiry of the limitation period which is referred to in sub-subsections 33(3)(a) and (b) and carries particular weight: Donovan at 478G. The court may also, however, have regard to the period of delay from the time at which section 14(2) was satisfied until the claim was first notified: Donovan at 478H and 479H-480C; Cain at [74]. The disappearance of evidence and the loss of cogency of evidence even before the limitation clock starts to tick is also relevant, although to a lesser degree: Collins v Secretary of State for Business Innovation and Skills[2014] EWCA Civ 717 , [2014] PIQR P19, at [65]. 9) The reason for delay is relevant and may affect the balancing exercise. If it has arisen for an excusable reason, it may be fair and just that the action should proceed despite some unfairness to the defendant due to the delay. If, on the other hand, the reasons for the delay or its length are not good ones, that may tip the balance in the other direction: Cain at [73]. I consider that the latter may be better expressed by saying that, if there are no good reasons for the delay or its length, there is nothing to qualify or temper the prejudice which has been caused to the defendant by the effect of the delay on the defendant's ability to defendant the claim. 10) Delay caused by the conduct of the claimant's advisers rather than by the claimant may be excusable in this context: Corbin v Penfold Company Limited[2000] Lloyd's Rep Med 247 . 11) In the context of reasons for delay, it is relevant to consider under subsection 33(3)(a) whether knowledge or information was reasonably suppressed by the claimant which, if not suppressed, would have led to the proceedings being issued earlier, even though the explanation is irrelevant for meeting the objective standard or test in section 14(2) and (3) and so insufficient to prevent the commencement of the limitation period: Hoare at [44]-[45] and [70]. 12) Proportionality is material to the exercise of the discretion: Robinson at [32] and [33]; Adams at [54] and [55]. In that context, it may be relevant that the claim has only a thin prospect of success (McGhie at [48]), that the claim is modest in financial terms so as to give rise to disproportionate legal costs (Robinson at [33]; Adams at [55]); McGhie at [48]), that the claimant would have a clear case against his or her solicitors (Donovan at 479F), and, in a personal injury case, the extent and degree of damage to the claimant's health, enjoyment of life and employability (Robinson at [33]; Adams at [55]). 13) An appeal court will only interfere with the exercise of the judge's discretion under section 33, as in other cases of judicial discretion, where the judge has made an error of principle, such as taking into account irrelevant matters or failing to take into account relevant matters, or has made a decision which is wrong, that is to say the judge has exceeded the generous ambit within which a reasonable disagreement is possible: KR v Bryn Alyn Community (Holdings) Ltd[2003] EWCA Civ 783 ,[2003] 3 WLR 107 , at [69]; Burgin at [16].”
