"There is considerable diversity in judicial opinion as to the extent to which, if at all, the rate or (more usually) the period selected for an interest award should as a discretionary matter be moulded adversely to a party that delays in the prosecution or defence of a claim where no resultant detriment to the other party is shown: see eg Geoffrey W Hill & Associates (Insurance Brokers) Pty Ltd v Squash Centre (Allawah North) Pty Ltd (1990) 6 ANZ Insurance Cases SS 61-012 ("[t]he principle of punishment is not borne out by a consideration of the purpose of the statutory discretion"); De Girolamo v South Australia (1991) 56 SASR 40 at 44-45; but cf Keates v Nelson (New South Wales Court of Appeal, Kirby P, Mahoney and Cripps JJA, 16 April 1992, unreported); Golden West Refining Corporation Ltd v Daly Laboratories Pty Ltd (Carr J, 16 February 1995, unreported): Tilbury, above, para 3230; and see also BP Exploration Co (Libya) Ltd v Hunt (No 2) [1979] 1 WLR 783 at 845-847 and McGregor on Damages, 16th Ed, 1997, paras 668-669. Nonetheless, insofar as concerns a successful applicant who has been guilty of unreasonable delay, the view I am prepared to follow in the absence of binding authority is that the period for which the interest award is made can properly be adjusted if to allow interest for the whole period for which it could otherwise be ordered would work an injustice to the respondent in the circumstances: cf Clarke v Foodland Stores Pty Ltd , above, at 400. Such would seem to be consistent with the policy of the s 51A (1) in that an applicant that has been held out of the benefit of its money because of its own unreasonable actions should not be allowed as of course to cast the effects of a `self-inflicted burden' onto the respondent: Keithara Pty Ltd v J G L Holdings Pty Ltd (Supreme Court of Victoria, Smith J, 6 December 1994, unreported)."
