C Scheme of the Limitation Act
13 Three provisions of the Act are of present relevance. The first is contained in Part 2, Division 1, which deals with periods of limitation and related matters. Section 14 relevantly provides:
(1) An action on any of the following causes of action is not maintainable if brought after the expiration of a limitation period of six years running from the date on which the cause of action first accrues to the plaintiff or to a person through whom the plaintiff claims:
(a) a cause of action founded on contract (including quasi contract) not being a cause of action founded on a deed
…
14 As noted above, it is, of course, common ground that any cause of action in relation to the Retainer Debts would have been a cause of action founded in contract.
15 The second provision is in Part 4, Division 1 of the Act. Section 63 in that division is relevantly in the following terms:
(1) Subject to subsection (2), on the expiration of a limitation period fixed by or under this Act for a cause of action to recover any debt damages or other money, the right and title of the person formerly having the cause of action to the debt damages or other money is, as against the person against whom the cause of action formerly lay and as against the person's successors, extinguished.
(2) Where, before the expiration of a limitation period fixed by or under this Act for a cause of action to recover any debt damages or other money, an action is brought on the cause of action, the expiration of the limitation period does not affect the right or title of the plaintiff to the debt damages or other money:
(a) for the purposes of the action, or
(b) so far as the right or title is established in the action.
…
16 The third relevant provision, also contained in Part 4, Division 1 of the Act, is s 68, which provides as follows:
Notwithstanding this Division, where:
(a) a person is in possession of goods, and
(b) the person has a lien on the goods for a debt or other money claim payable by a second person,
the right and title of the first person to the debt or other money claim is, as against the second person and the second person's successors, saved from extinction under this Division for so long as a cause of action of the second person or of a person claiming through the second person for the conversion or detention of the goods or to recover the proceeds of sale of the goods has not accrued or is not barred by this Act, but only so far as is necessary to support and give effect to the lien.
17 The scheme of limitations in New South Wales differs materially to those places in Australia where the effect of the limitation period having run is to bar the remedy rather than the right, because in New South Wales, the cause of action is extinguished upon expiration of the relevant limitation period (this is somewhat of a generalisation because even in places where the bar is on the remedy rather than the right, there are specific legislative provisions in some States or Territories providing for extinguishment of various rights, though those provisions are presently immaterial).
18 Where the effect is to bar the remedy, but not extinguish the right, it follows that the right (or underlying cause of action) remains in existence, but can no longer be enforced by action or set-off. As is explained by Professor Handford in Limitations of Actions - The Laws of Australia (4th ed, Thomson Reuters, 2017) at 75 [5.10.510]:
Thus, a statute-barred debt remains due and may be enforced by other means, such as the enforcement of a lien or security, or if the debt was incurred as the result of a tort, as damages in a tort action. Money paid to a creditor without appropriation can be appropriated to a statute-barred debt provided the debtor has knowledge. A personal representative is bound to plead the Limitation Act only if required to do so by a beneficiary or creditor. It has been held in England that an executor of a solvent estate may pay a statute-barred debt unless a court has adjudged it to be statute-barred, but it seems that this is unlikely to be followed in Australia. A trustee may pay statute-barred debts even if the beneficiaries object, and a personal representative may set off a statute-barred debt against a pecuniary or residuary legacy (but not against a specific legacy). However, statute-barred debts cannot be proved in bankruptcy, or generally in the liquidation of a solvent company.
The Limitation Act 1969 (NSW), unlike any other Australian Limitation Act, is based on the principle that, on the expiration of the limitation period, the cause of action should be extinguished and not merely barred. Accordingly, the right and title of a person having an action for debt, damages and other money recoverable by action or an action for an account is extinguished on the running of the period.

19 As is noted in this passage, it has been held that an executor of a solvent estate may but is not obliged pay a statute-barred debt, but reference has been made to this principle being unlikely to be followed in Australia. I think the situation is somewhat more complicated than that and I will return to this issue below.
20 The passing of the Act was preceded by a report of the New South Wales Law Reform Commission, entitled The First Report on the Limitation of Actions [1967] LRC 3 (LR Report), to which I was taken by counsel for the respondents, Ms Castle. It seems to me that the LR Report is of some significance as an aid to construction, particularly as to how one is to approach s 68 of the Act. No party objected to me having regard to the LR Report and it is appropriate to use it as an aid to ascertain the meaning of the provision: see ss 34(1) and 33(2)(b) of the Interpretation Act 1987 (NSW). The LR Report was produced, of course, against the background that the general law of limitations in force in New South Wales in 1967 was the same as was in force in England in 1837 and rested, in main, on Imperial Acts passed many years before. One of the changes addressed in the LR Report was said to be of "basic importance to the principles of the law of the limitation of actions" being the "extinction of rights and titles on the expiration of the limitation periods for actions for their enforcement". At [14] of the LR Report, the following was noted:
Before 1833 in England and 1837 in New South Wales, the expiration of the limitation period only barred the remedy by court action and not the right, whether the right was a debt, a claim for damages, a title to land, or any other right. By the Acts of the 1830's, the expiration of the limitation period for an action to recover land worked an extinction of the title of the claimant to the land, but the law in this respect was otherwise unchanged. The Imperial Act of 1939 extinguishes a title to goods on the expiration of the limitation period for an action for the conversion or detention of the goods, but leaves the law otherwise unchanged. The Wright Committee, indeed, considered the problem and did not recommend that any change be made. We think, however, that the extinction of the claim or title should be made the general rule. Leaving the claim or title in existence without the support of a remedy by action is to leave settled expectations open for ever afterwards to disturbance by accident or by contrivance. We discuss the matter in more detail in paragraphs 306 to 330 of the notes which are appendix C to this report. Of those whom we consulted on the effect of the Bill generally, a substantial majority were in accord with our proposals for the general extinction of rights and titles on the expiration of the relevant limitation periods.
21 The reference to the Wright Committee in the above passage was, of course, to the Law Revision Committee Fifth Interim Report: (Statutes of Limitation) of 1936, which gave rise to legislative change in the United Kingdom. When turning to ss 63 and 68 of the Bill which later became the Act, the following appeared in the LR Report:
[306] This group of sections, sections 63 to 68, embody a major change in principle, although concerned with a problem which has not frequently arisen in the reported cases. It is a change to which we have referred before and the proposal is that it be made a general rule that, on the expiration of the limitation period for a cause of action, the personal right to debt, damages or other money, or the right of property, which the cause of action would enforce is to be extinguished.
…
[313] The fifth case considered by the Wright Committee concerns liens and charges. A solicitor's lien may be enforced after his costs are statute-barred, so may a wharfinger's lien and it may be that any kind of lien can be enforced after the claim which the lien secures is statute-barred. An equitable charge on shares can be enforced, by action for foreclosure or sale, though the debt for which it is security is statute-barred.
[314] The Wright Committee considered that tar the most important matters were dealt with in this fifth case and that here again it seemed very doubtful what effect, if any, the extinguishment of the debt would have on collateral rights against property. The Committee referred to its earlier recommendations that limitation periods be fixed for the recovery of money charged on personal property (twelve years, see now Imperial Act of 1939, s. 18 (l)) ; for the recovery of arrears of interest on money charged on personal property (six years, see now Imperial Act of 1939, s. 18 (5) ; and for foreclosure in respect of mortgaged personalty (twelve years, see now Imperial Act of 1939, s. 18 (2)). Actions to enforce liens and charges (including foreclosure actions) would be governed by those provisions. But those provisions would not affect the case where a creditor has in his possession a security which he could enforce without bringing an action, nor did the Wright Committee think that the right to enforce such a security in such circumstances ought to be limited. A creditor naturally refrained from bringing an action so long as he held an ample collateral security, and it would be inconvenient to both parties if he were compelled to enforce the security or lose his right altogether. The Committee did not desire to bring this about.
[315] We think that the case of a possessory lien on goods requires special treatment. We would save a debt secured by possessory lien on goods from extinction for as long as the owner of the goods has a cause of action for the conversion or detention of the goods or to recover the proceeds of sale of the goods, but only so far as is necessary to support and give effect to the lien. Section 68 of the Bill so provides. A possessory lien is not within the definition of "mortgage" in section 11 (1) of the Bill.
(Italics in original)
22 Having set out the above, it seems to me that the statutory intention is quite plain. The rationale of s 68 of the Act arises by reason of the introduction of the notion of extinguishment in s 63. Without a provision such as s 68, the holder of a lien (of which, as noted above, several types were considered) would be compelled to enforce the security (if such a lien was capable of enforcement) prior to the expiration of the limitation period or lose it altogether on the basis that the underlying debt would, by force of s 63, be extinguished.
23 In circumstances where the type of lien held was, in contradistinction to the current circumstances, one which gave active rights, such as the ability to exercise the power of sale (for example a wharfinger's right to sell the property the subject of a lien) or a charge on shares enforceable by foreclosure or sale, s 68 of the Act acts so as to preserve the right of the holder to exercise the lien. Of course, s 68 does not transmogrify or augment the nature of the right which the lien represents. As I previously explained, the lien in issue here is merely passive and possessory, and hence s 68 does not create any rights in relation to the lien.
24 It follows from the above analysis that the principled construction of s 68 of the Act is that where a person lawfully maintains a lien, the right and title to the debt that it supports is not extinguished, but only insofar as it is necessary to maintain the lien (that is, to exercise whatever rights the particular lien provides, given its nature). As can be seen from the LR Report, s 68 is only necessary because of the concept introduced in s 63 of extinguishment, because a lien is only able to be maintained when the debt, underlying it, exists.
