To close off, two related points of clarification are apposite. The first relates to the use of the “debt” characterisation by some commentators and courts as referring only to the substitutive measure of a trustee’s or custodial fiduciary’s liability pursuant to a falsification order, and not the reparative measure under a surcharging order. It is necessary to appreciate that the use of “debt” in this sense is for a different purpose and meaning than the use of “debt” as a synonym for “a claim for a liquidated sum”. In the latter usage, the quality of a “debt” that is being emphasised is that “the process of quantification is already complete”, this being the “decisive hallmark of a liquidated claim” (see Ian Fletcher, The Law of Insolvency (Sweet & Maxwell, 5th Ed, 2017) at para 6-047). But, in the former usage, the description of a substitutive performance claim as analogous to “debt” is in contradistinction to “damages” as describing a reparation claim, in order to connote that only reparation claims are in the nature of compensation for loss properly so-called, such that the usual rules limiting recoverability of damages – eg, doctrines of causation and remoteness of damage – apply to reparation but not substitutive performance claims (see, eg, the Supreme Court of Western Australia decision of Agricultural Land Management Ltd v Jackson and others (No 2) (2014) 98 ACSR 615 at [334]–[349]; Navigating the Maze at para 42).
