Abstract

This paper explores Peter Jaffey’s views on the trust and fusion and some aspects of his wider private law theory which impact on his view on trusts law. It shows that, although he is correct that the trust involves both proprietary and personal rights, in the end his theory is ahistorical and unDworkinian, despite his acceptance of a view of law based on Dworkin. His theory is also based on implausible views of the role of equity post-Judicature Acts and the ownership of value and does not adequately fit how trusts law works.

In a paper some 10 years ago, I examined and critiqued Peter Jaffey’s private law theory and his application of the theory to the law of restitution.Footnote 1 Jaffey’s theory, however, has some profound effects on the law of trusts and that of tracing as well.Footnote 2 Indeed these effects are linked to his views on unjust enrichment in that he rejects altogether the idea of a law or principle of unjust enrichment in favour of many (but not all) such claims being property claims enforced via a trust. Other claims that might be placed into unjust enrichment are reclassified by Jaffey as contractual, and the division between contractual and proprietary is also important to Jaffey’s treatment of trusts. Jaffey argues that both aspects, the property aspect and the contractual or obligationary aspect, are necessary to explain the trust. He denies that the trust is a hybrid and keeps these two dimensions very separate.Footnote 3 Jaffey argues, “The trust has two separate parts which operate together without mixing, and the beneficiary’s equitable interest consists of distinct personal and property rights.”Footnote 4

This paper examines Jaffey’s theory as it applies to the trust and the law of tracing, and also his views on the substantive fusion of law and equity. There has been increased interest in these fundamental questions about the nature of trusts and fusion recently. If correct, however, Jaffey’s theory has some profound and radical implications for the nature of the trust and indeed the nature of ownership and so it is timely to take a look at his views. The article takes two main lines of attack. The first is that Jaffey’s theory of the trust does not fit English law. Jaffey’s division of trusts into a proprietary and contractual aspect, while attractive in some ways, does not appropriately characterise the proprietary rights that the beneficiary does have. In particular, Jaffey mischaracterises the interest of the beneficiary as an interest in ‘value.’

The second line of attack is on Jaffey’s wider private law theory and some of his wider commitments which force him to implausible positions on the trust. The first commitment is to remedial consistency. The requirement of remedial consistency is that the remedy which a court gives must reflect and secure the content of the primary relation between the parties. Jaffey’s second commitment is to the idea that unconscionability has relevance only to a historical rather than a principled account of the law of trusts,Footnote 5 and that a historical account is different from, and cannot help with, a principled account. In its second line of attack, this paper challenges both commitments. The principle of remedial consistency is flawed in theory, but also fails to represent the truth about English trusts law in that the account of administration in common form is a personal remedy dependent on the invalidity of transfers, not on a proven wrong of breach of trust. If the principle of remedial consistency is flawed, however, it also suggests that the need to keep the two sides or dimensions of the trust separate is illusory.

Indeed, historically it seems they were not kept separate and so the principle is ahistorical. Using it to justify the two dimensions of the trust fails to take the development of the trust into account and the paper uses one account of the trust’s development, Lionel Smith’s, to demonstrate that the trust is a classic example of English law (or equity’s) doing precisely what Jaffey says is impermissible, developing a proprietary remedy from a personal right. If so, this suggests deep problems with Jaffey’s commitment to the idea that there is a hard distinction between principled and historical accounts. This is supported theoretically. Jaffey has in the past accepted a version of DworkinFootnote 6 and yet his theory seems to run counter to it. For Dworkin there is no hard distinction between principle and history. Explaining the law involves looking at fit with prior decisions as well as an examination of their justification with an eye to future decision-makers.Footnote 7 It is both forward and backward looking.Footnote 8 Jaffey, however, in insisting on the irrelevance of history, posits a static system that cannot account for the development of concepts over time. This in turn suggests problems with a third commitment of Jaffey’s, which I challenge more indirectly, that each area of the law must be a justificatory category.Footnote 9 By justificatory category, Jaffey means a category comprising claims arising out of a unique normative rationale, so each category has a rationale applicable only to that category.Footnote 10

1. An Outline of Jaffey’s Trusts Theory

In this section of the essay, I clear the ground with a brief summary of Jaffey’s position. The second section critiques some specific aspects of his theory of trusts. Jaffey argues that neither a purely proprietary nor a purely obligational theory can succeed. He takes Ben McFarlane’s view to be an example of the obligational theory. McFarlane argues that the trust is made of a right against a right, i.e., a right that the beneficiary has against the trustee that they use their legal (or equitable) rights in a particular way.Footnote 11 Jaffey argues that this cannot explain the trust. This is because it is contrary to the principle of remedial consistency,Footnote 12 sometimes referred to as the monist principle. The principle of remedial consistency is simply put. A remedy can only be justified by reference to its match with the primary relation between the parties.Footnote 13 A proprietary remedy effective against third parties cannot therefore be justified by reference to a personal obligation between the trustee and the beneficiary, nor can the priority over the trustee’s creditors in bankruptcy.Footnote 14 A purely proprietary theory also fails. It fails because it cannot explain the demonstrable fact that the trustee has an obligation to look after and distribute the trust property according to the trust.Footnote 15 For Jaffey, the trust’s two dimensions are therefore

  1. 1) The allocation of property rights

  2. 2) Undertaking to distribute and hold the rights according to that allocation.

The idea of the two dimensions of the trust therefore exposes different possibilities. One such is a trust in the contractual aspect only; this might reflect the Civilian or mixed jurisdiction view of the trust.Footnote 16 Under such a view, third party recipients could only be liable on the basis of complicity in the trustee’s wrongdoing and there would be no protection against the trustee’s creditors.Footnote 17

The suggestion that the trust is made up of a complex of property and personal rights is not new. Nolan has argued that a trust beneficiary has a negative exclusionary right, which is the common proprietary right linking examples of equitable property and a set of positive rights which can be put together as needed by the circumstances.Footnote 18 Jaffey’s distinctive allocation of rights into two dimensions, however, emerges from the power of the settlor to grant property rights in the asset.Footnote 19 That power explains how the property rights are divided up. For Jaffey, the trustee has the right of control over the property and the beneficiary has the benefit of it. Control rights are at the core of what Jaffey in earlier writing called dispositive title.Footnote 20 The trustee is able to dispose of the asset without reference to the beneficiary. The allocation of benefit (or some part of it) to the beneficiary lies behind the trustees’ having to hold the proceeds on trust, and Jaffey describes property rights as being rights to the benefit or some part of the benefit of property.Footnote 21 The allocation does not explain the trustee’s obligation to distribute and hold the rights according to that allocation. That is explicable by reference to the trustee’s agreement or consent. All that is implied by the property dimension, therefore, is that there is a power in the beneficiary to lay claim to the assets or their surviving value in the hands of the trustee or third parties and consequent immunity from third party creditors’ rights held within the trust. The reference to value is important; the right to trace into exchange products is inherent in ownership because the beneficiary owns the value of the assets, inherent in whatever the proceeds might be.Footnote 22 Jaffey therefore splits legal and equitable ownership but eschews the ‘dual’ or ‘split’ ownership approachFootnote 23 where the beneficiary owns in equity and the trustee at law. That view where both jurisdictions claim their man is the owner and equity prevails,Footnote 24 making the equitable owner the true owner is false.Footnote 25 It also seems a straw man because nobody really argues for that simplistic view. Rather it seems better to see the trust as being where the trustee has a set of rights over the property but has duties regarding the asset’s management. Put differently, the trustee has a set of legal powers regarding the assets, but duties as to how they are to be exercised.Footnote 26

I examine the implications of the split in title later, but it is entirely separate from the contractual or obligational aspect of the trust. Agreement is at the heart of Jaffey’s views on how contract is justified. Importantly for Jaffey it is not actually an agreement to do something that matters in a contract. The agreement consists of assumptions of responsibility for the reliance of the other party on their promise.Footnote 27 There are real issues with Jaffey’s explanation of contractual remedies, which I have explored in some depth elsewhere.Footnote 28 Jaffey is not saying that the trust agreement is a contract in its technical sense, however. He expressly accepts that the rules may depend on other considerations, but the trustee cannot be subject to an obligation to look after and distribute the trust property other than by their agreement.Footnote 29 A trustee plainly must consent to be subject to elaborate obligations, such as to invest the trust assets.Footnote 30

2. Specific Critiques of Jaffey’s Trusts Theory

This section is divided into two subsections, which relate to specific aspects of Jaffey’s trusts theory. In the first subsection I examine the rights that a trustee has to control or manage the assets and to sue for interference with those assets, the obligations they have vis-à-vis the beneficiary, how they arise, and, critically, also the remedies available in the case of misapplication of the trust assets. I compare those remedies with the remedies available in knowing receipt. In the second subsection I examine the misrepresentation of value in Jaffey’s theory and argue it is confusing and requires a new, completely unrecognised, proprietary right to be developed.

(A) Control Title and Beneficial Title

This subsection is divided into two. In the first part I examine the control rights that the trustee has. Jaffey’s analysis here has the merit of reflecting the rights that the legal owner has to control the assets and to sue for interference, rights denied to the beneficiary who cannot sue a third-party converter. In the second section, however, I show that Jaffey’s assertion that the agreement of the trustee compels them to hold and distribute the assets is questionable. Knowledge is key, but in the context of the express trust, Jaffey omits any consideration of this. It is also difficult to see how the beneficiary can have property rights in the assets (or their proceeds) when the claim that they be held for them exists in a different contractual dimension. Nolan, for instance, has commented that the duality of title and the negative exclusionary right in the beneficiary is backed up by the action to recover assets and restore the integrity of a fund depleted without authorisation.Footnote 31

(i) Legal Owner as Having Control Rights

Control or managements rights are at the heart of Jaffey’s view of the trustee’s legal title.Footnote 32 Consequently, the trustee has the exclusive right to sue for interference with the asset. That latter point is supported by case law such as MCC Proceeds Ltd v Lehman Bros,Footnote 33 and this aspect of Jaffey’s theory poses few issues. Yet, parenthetically, there is nothing particularly ‘trust-sy’ about control rights. The trustee has these control rights because (in the usual case at least) they have legal title and legal title brings with it a number of powers and incidents, including the ability to possess, use, dispose of the asset, etc.Footnote 34 The important thing is what they can (or not) do with these powers and how they can exercise them.

This is different from the equitable owner’s rights. Returning to MCC Proceeds, the Court of Appeal said conversion was unavailable to a trust beneficiary, who does not have the necessary underlying right to possession. In International Factors Ltd v Rodriguez,Footnote 35 Sir David Cairns appears to suggest that fusion meant equitable rights could give an entitlement to sue in conversion. However, fusion does not change our substantive rights;Footnote 36 it simply compels symmetry between actions protecting similar things. In fact a conversion action was allowed on the basis the claimants had a right to have possession of the cheques in question. Despite suggestions in Shell (UK) Ltd v Total (UK) Ltd Footnote 37 that a trust beneficiary should be able to sue in negligence, conversion protects possession, and since there is no such thing as equitable possession, trust beneficiaries should not be able to sue directly even if they can procedurally take over the trustees’ action if the trustee refuses to sue.Footnote 38 The trustee also has the exclusive right to deal with the dispositive title and transfer it to a third party. If that transfer is unauthorised, the equitable title is not overreached and the transferee acquires legal, but not equitable, title, unless they are a bona fide purchaser.Footnote 39 Absent bona fide purchase the beneficiary has the right to reclaim the asset for the trust, which does not necessarily mean that the third party holds directly on trust for the beneficiary.Footnote 40

(ii) Knowledge, Consent, Breach of Trust, and Knowing Receipt

It is in the relationship between trustee and beneficiary that the problems really begin with Jaffey’s theory. A totally ignorant ‘trustee’ has no obligations. That does not mean that the beneficiary has no rights. They do. They have equitable proprietary rights and therefore immunity to the claims of third-party creditors. Jaffey would probably say there is no trust, or a trust only in the property dimension. To some extent this is semantics.Footnote 41 What matters is that the asset can be claimed in preference to creditors. The beneficiary, assuming they know of the attempt to settle a trust, can simply inform the trustee of its existence. If they do so, the trustee will be liable to a claim for substitutive equitable compensation or, in more traditional terms, an account of administration in common form if unauthorised disbursements of trust funds are made.Footnote 42 This ability in the beneficiary to inform the trustee is not a legal power in any Hohfeldian sense; it is a purely factual ability. If the ‘trustee’ knows, they become liable, and this is sometimes expressed in terms of the trustee’s conscience being affected.Footnote 43 It is pretty much impossible to claim in priority to creditors without telling the ‘trustee’ or their trustee in bankruptcy, so in practice any time a proprietary claim is made for priority it will trigger the trustee’s obligation to keep the assets safe. For any further liability, however, such as for failing to invest the assets, the trustee must consent to the whole package of trust duties involved in the given trust.Footnote 44 The requirement for consent, which is frequently framed in a contract, makes it not completely inapt to talk of a contractual (or certainly consensual) dimension to trust law, and investment obligations (say) are definitely personal. It is plainly impossible to sue a third party because of the negligent investment made by a trustee.Footnote 45

There is, however, no need to prove a breach of trust to obtain an account in common form.Footnote 46 All the beneficiary needs to do is request an account of the stewardship of the property. The language of ‘account’ is entirely appropriate in the colloquial sense. The beneficiary asks for an account in a prescribed form of how the trust assets have been used. The beneficiary may then object to a given entry, and an ancillary order to pay any amount due can be made.Footnote 47 If assets are disbursed without authority, the account is falsified.Footnote 48 Since the law pretends the disbursement never took place the original assets from the trust fund must still be in the trust fund and any expenditure is treated as if it were the trustee’s own; if specific restoration is impossible a money obligation is substituted.Footnote 49 This is a purely personal remedy,Footnote 50 but as a doctrinal matter is bound inextricably to Jaffey’s property dimension. Jaffey repeatedly makes claims along these lines:

Invalidity relates to the transfer of property in the property dimension and breach of trust to breach of the trustee’s duty in the contract dimension. As a matter of remedial consistency, the breach of duty by the trustee generates a claim for compensation against the trustee … and the invalidity of the transfer generates an equitable proprietary claim against the recipient.Footnote 51

Yet this is wrong. There is no need to prove a breach of trust, or to put it in different terms there is no need to prove the breach of a duty. The order against the trustee to pay money is not a secondary obligation to pay compensation, but enforcement of the trustees’ custodianship, and amounts to a kind of substitute performanceFootnote 52 (subject to limitations on the trust’s needing to be continuing and on foot). This is an aspect of the performance interest in trusts: that the trust be performed and that the court be able to step in and perform it if the trustee will not or cannot.Footnote 53 Trusts law therefore focuses, in this context, on restoring the fund to its duly administered state, not on reversing harm.Footnote 54 As Ho and Nolan point out, this is significantly different from the aim of contract damagesFootnote 55 (or for that matter tort damages) and this is reflected in the fact that causation is generally irrelevant to a common account.Footnote 56 Two points come out. First, invalidity of the transfer (which is in the property dimension) triggers the remedy against the trustee. Secondly, the remedy is personal, when presumably remedial consistency demands it be proprietary.

It might be possible for Jaffey to remodel his views. He could first argue for a change in the law to insist on consent, not merely knowledge, and for a proven breach of duty. He might note that it is not unknown to talk of a performance interest in contractFootnote 57 and seek a greater role for causation in the assessment of equitable compensation. Jaffey, however, recognises the lack of need for full agreement in the context of knowing receipt where he refers to a “tort” or “negligence” dimension of trust law.Footnote 58 An alternative open to Jaffey might therefore be to accept a ‘tort’ dimension to express trusts as well.

Currently he does not accept this. Knowing receipt is best seen as a wrong, and one parasitic on the existence of a proprietary claim, and is not, say, an unjust enrichment claim.Footnote 59 The precise degree of knowledge needed remains controversial, but so long as the recipient does not have notice for the purposes of any bona fide purchase defence, they may well be a knowing recipient.Footnote 60 Innocent donees are not knowing recipients, but purchasers for value with sufficient notice are subject to liability, and this is a very old rule.Footnote 61 Knowledge is the critical point; the beneficiary may enforce their interests against party A, who knew of the breach, even after it has been transferred (and re-transferred back) to a bona fide purchaser.Footnote 62

One immediate objection is that Jaffey’s argument is internally inconsistent, which is why the alternative remodelling mentioned earlier of recognising a ‘tort’ dimension in express trusts may be the better option for Jaffey. Why, using Jaffey’s terms, if a (knowing, but un-consenting) recipient, on becoming aware of the invalidity of a transfer, becomes subject to a ‘tort’ duty should the knowing, but un-consenting, trustee not also be subject to a ‘tort’ duty? The second objection to Jaffey’s thesis is that in fact neither is subject to a tort duty. From a remedial perspective the express trustee and knowing recipient are in the same positionFootnote 63 even though the recipient is not subject to the same fiduciary or other duties to which the express trustee is subject.Footnote 64 The recipient must receive property to which the claimant was entitled and has a primary duty to restore the value of the misappropriated property because he is liable “to deal with the property as if he were a trustee.”Footnote 65 This explains references to liability as a constructive trustee: liability as if the recipient were an express trustee even though they are not.Footnote 66

Jaffey rejects the analogy with express trustees,Footnote 67 however, arguing the recipient has not undertaken to act as a trustee. He argues that there are two components of the knowing receipt action: the restitutionary claim to recover the value of the property and the compensatory claim for loss. Jaffey goes on to argueFootnote 68 that knowing receipt is the equitable analogue of conversion; conversion too, he says, is a hybrid of a property action for the return of the value transferred and a compensation action where that is impossible. It is difficult, however, to see the knowing receipt claim as a restitutionary claim. It is frequently available against third parties, and personal restitutionary claims cannot normally reach so far. That leaves only the compensatory aspect of knowing receipt, which is, as noted, dependent on a duty of stewardship triggered by the same event as that of the express trustee: knowledge. It is this, as seen above, that provides the analogy with express trusts. The parasitism on another action (the proprietary claim) provides a disanalogy with conversion.Footnote 69 The tort dimension is not therefore, as Jaffey puts it, “the non-contractual counterpart, in the remedial context, of the contractual dimension in the express trust.”Footnote 70

(B) Value and Tracing

None of these criticisms are, however, fatal. They simply cannot be said to go to the heart of Jaffey’s theory; although Jaffey’s mischaracterisation of the performance interest in trusts as contractual comes close, he may be able to introduce a tort dimension to express trusts. The criticism in this section does seem fatal, though. No amount of remodelling can save Jaffey’s theory from failure.

Many of Jaffey’s problems are caused by his insistence that abstract value can be owned. This lies behind his view that when a mistaken transfer of assets takes place, the transferor retains ownership of the abstract value even though the control of the specific asset has moved. It also lies behind his subscription to a variant of the trust fund theory. Penner also subscribes to such a theory, although, unlike Jaffey’s theory, Penner’s view is a pure proprietary view.Footnote 71 Penner believes that the beneficiary’s interests are essentially future-oriented.Footnote 72 He argues that the beneficiary’s interest is in the power of the trustee to manage the funds through investment and re-investment.Footnote 73 The beneficiary automatically obtains an interest in the proceeds, because an interest in the power to exchange simply is an interest in the fruits of its exercise.Footnote 74 This Penner describes as proprietary reasoning par excellence and reflects the beneficiaries’ real interest in potential wealth,Footnote 75 and the fact that I can never have an asset and its value simultaneously.Footnote 76 Value, or more precisely relational value, is a means of quantifying equivalence between qualitatively heterogenous things. Value is not owned or transferred; it is realised. If I realise the exchange value of my asset, I relinquish the asset and all rights to it to the buyer.Footnote 77 Penner concludes that I do not own the value of the asset; I own the asset itself. Value, not being a separable thing itself, cannot be separately owned.

Jaffey’s views can, however, only be accepted if value can be separated from the concrete asset. Abstract value must be an objective phenomenon, separate from the value anyone might put on it. It bears repetition therefore that according to Jaffey the trust beneficiary owns the abstract value of the fund separate from the individual assets.Footnote 78 There is no need, however, to reify the fund as an object of property.Footnote 79 The fund has no separate legal personalityFootnote 80 or legal identity. It is always the individual assets that matter. The beneficiary has an immediate overreachable interest in particular assets,Footnote 81 which on an authorised transfer are detached and reattached to the proceeds of the old asset. Limitations on the trustee’s authority to deal with the specific assets tells us when, how, and whether the beneficiary’s rights are transferred to another asset. In fact, it makes no sense for Jaffey to say that the trustee has control interests in specific assets, but the beneficiary’s interest is held in a fund, separate from the assets controlled by the trustee. If the beneficiary has a proprietary right of any sort it will be in a specific asset. A trust fund therefore only exists when a set of assets is demarcated by being taken out of the legal owner’s full control.Footnote 82 The trustee’s equitable obligations to the beneficiaries provide this demarcation from other assets to which they have legal title, and a breach of trust obligations can only be identified if an asset misused is identified. Indeed, a fund cannot be identified without identifying the assets within it. The individual assets are consequently the critical feature.

Jaffey’s idea causes real trouble if the trust does not operate normally. Tracing comes in here. The purpose of tracing, Jaffey argues, is in essence to decide where, after an unauthorised payment, the surviving value lies.Footnote 83 Jaffey explains, “[t]here is always a subsisting … property right, though not in a specific asset. Surviving value cannot be duplicated or multiplied, although it can be divided and distributed to different people. Its location is a matter of causation.”Footnote 84 In the money context this is because of the fungibility of money. It matters not which £10 I have, only that I have £10, but Jaffey extends this to all forms of asset. Orthodox English tracing rules reject causation even in equity. Foskett v McKeown Footnote 85 is a classic example of a case where a tracing link was present, but no causation link. The life insurer would have paid out on the policy even had the premiums paid with misappropriated trust money been left unpaid. On Jaffey’s view the life insurance beneficiaries should win, as no causal connection exists between their payout and the trustee’s use of misappropriated funds. A view of tracing that condemns the leading English appellate decision as wrong begins badly.

This insistence on causation also allows for a complete de-mooring of proprietary rights from specific assets, with strange conceptual consequences. Jaffey argues that the basis for the law of tracing is simply that beneficial owners have a right to the exchange value of the asset.Footnote 86 This does not, however, entail any subscription to the exchange product rule or principle.Footnote 87 That rule is that if a cow (to which the claimant has an equitable proprietary claim) is exchanged for a goat, the claimant’s property right is transferred to the goat.

Jaffey argues that there are no theories to adequately explain such a transmission of property rights between individual assets in this way.Footnote 88 He concludes therefore that if no explanation can be given for how property rights move between assets, the claimant cannot have rights over any particular given thing. The claimant has an interest instead in recovering value.Footnote 89 Consequently the defendant’s estate is a body of abstract wealth to which the claimant has a share, that being the part of the abstract value derived, causally, from the invalid transfer. At the time of the invalid transfer, the surviving value will be the value of the asset transferred.Footnote 90 If the asset is destroyed or damaged, it will be worth less and the measure of the claim reduced. There may be surviving value in the estate even after the original asset is disposed of.Footnote 91 A proprietary claim is not a claim to restitution of a specific asset unless the “surviving value … has not diminished and the value of the asset does not exceed the surviving value in the estate.”Footnote 92 This is in effect the (discredited) swollen assets theory and Jaffey endorses it. He endorses it in a particular way though. He suggests that the proprietary right is akin to a floating charge,Footnote 93 in not being attached to particular assets, but it is not a charge because it is not to satisfy the discharge of a debt.Footnote 94

Jaffey’s new proprietary right has no parallel. It is neither a security right, although it is akin to one, nor a right in any particular asset. No case has ever recognised such a property right; indeed, quite the contrary, the courts have repeatedly required that there be certainty as to the asset in which one might have a proprietary right; this explains why one need not—indeed should not—accept Jaffey’s characterisation of a fund. Jaffey’s logic is also troublesome because it extends further than he himself might wish. Section 16 of the Sale of Goods Act 1979 (UK), for example, requires that specific assets be identified before legal title passes in a sale, and Re Goldcorp Exchange Ltd Footnote 95 is often held up as an example of a case requiring certainty of subject matter. Yet it would be conceptually possible on Jaffey’s logic to say that, before assets are identified where a buyer agrees to buy 100 gold bars and the seller has not yet appropriated 100 gold bars from the 1000 in the warehouse to the contract, property in the value passes to the buyer, essentially giving the buyer a 10% tenancy in common interest and an interest in the abstract value held by the seller. The analogy is with quasi-specific goods and with sections 20A and 20B of the Sale of Goods Act 1979 (UK), and would extend the rule in those sections beyond the context of the fungible bulk. This would have difficult insolvency consequences (as indeed do many of Jaffey’s proposals).

The logic of Jaffey’s position is that ownership of a thing carries with it automatic ownership of substitutes and proceeds, i.e., an interest in the abstract value inherent in the thing. Although odd for an English lawyer, the idea of a legal interest in a fund is not completely alien to common law systems. It seems to some courts the best explanation of a security interest under a Personal Property Security Act.Footnote 96 Yet the cases suggest owners do not have automatic common law rights to proceeds of either tangibles or (at least some) intangibles.Footnote 97 If so, automatic rights to traceable exchange products (or traceably surviving value, in Jaffey’s terms) in the hands of a converter do not exist. If I take your cow and swap it for a goat, do you have a legal claim for the goat? No. In the absence of a pre-existing relationship, such as in R v Bunkall, Footnote 98 there is no authority for such automatic exchange product rights at common law. Jaffey suggests, however, that when I convert your cow, the common law lacks the conceptual apparatus to recognise this type of proprietary claim and this type of interest in abstract value, and that the claim be provided by equity instead to fill the gap.Footnote 99

But there are two points. First, as a matter of fit, the cases suggest that no such claim exists, the converter does not hold the cow or the goat on trust,Footnote 100 and yet Jaffey’s theory drives us to creating the claim to compensate for the law’s alleged remedial inadequacy in providing only damages or a statutory order for redelivery.Footnote 101 Secondly, why does substantive fusion not require the common law to develop its own equivalent claim, or to recognise the concept of interests in abstract value? Jaffey argues substantive fusion is about removing a spurious justificatory category (equity) and allowing analogical reasoning to reach its proper potential. That implies the need for an analogous common law proprietary claim to the goat (or some asset of equivalent value in the defendant’s estate), blurring the line between legal and equitable title, extending the type of legal fund analysis used in some Canadian Personal Property Security Act cases, and thereby driving a radical and unacknowledged fusionist outcome.

Jaffey responds to the objection that introducing an equitable proprietary claim in common law restitutionary claims involves substantive fusion by saying we need not go so far “for present purposes.”Footnote 102 The provision of an equitable remedy for a common law claim is common enough, as Jaffey accepts. The relevance of substantive fusion lies instead in whether the common law ought to develop a similar claim of its own: for our purposes, in the conversion context. Jaffey seems, obliquely, to leave this open “as part of the natural process of development over time of the common law”Footnote 103 and therefore to accept at least the potential for these radical implications as to legal title.

Jaffey’s characterisation of the right as a floating right to take assets to the limit of surviving value also implies the availability of change of position. The defence arises in the usual case, for example where A transfers an asset to B by mistake (say) and B then incurs an extra-ordinary expense in reliance. B changes their position. For Jaffey, seeing the proprietary claim contingent on tracing purely as one to surviving value allows us to reorient change of position as a limit to proprietary claims. It does not matter if the claim is against the original asset or against the traceable proceeds of the asset. Change of position is built into the tracing rules. B has less abstract value causally related to the initial transfer than they had at the time of that transfer and their liability should be reduced accordingly.Footnote 104 For Jaffey, it is an advantage of his causal approach that it explains and justifies the availability of the defence to the initial recipient,Footnote 105 but also their successors in title.Footnote 106

Although there is no clear authority on the question, Jaffey is right that the defence should be available to successors in title. Its availability can, however, be better explained in other ways. The third party defendant who, having received a payment (perhaps made in breach of trust), and who then draws on an unconnected bank account in reliance on this receipt to pay for a posh dinner is, morally speaking, in the same position as the initial recipient in a personal claim for a mistaken payment. Their freedom of choice should be respected, and this should not depend on an arbitrary decision as to which bank account to pay from. The defence works differently to its operation in personal claims, where it simply reduces the quantum of relief, in that it becomes set off against the return of the specific asset to which the claimant is making a claim,Footnote 107 but the essence of it is the same.

Two other final points of criticism are worth making for completeness, although neither is fatal for Jaffey. First, let us assume I use money from a trust fund to buy a grandfather clock. If the price of the grandfather clock rises it is reasonable to assume that I would have taken advantage of that and the “value of the asset remains the correct measure of the surviving value.”Footnote 108 But if an innocent defendant increases the item’s market value (perhaps by repairing it), the claimant should not automatically be entitled to the increase in value,Footnote 109 because the innocent defendant should not be left empty-handed after their efforts. Surviving value is here less than the asset value.Footnote 110 It is impossible to avoid the conclusion that ‘value’ can mean different things and confusion is likely to reign. Talk of value becomes unhelpfully metaphorical.Footnote 111

Secondly, if in the cow for goat swap the cow is still there (and the possessor not a bona fide purchaser), presumably the claimant could claim the cow? Does surviving value not causally subsist in the third party’s estate? This is the problem of geometric multiplication, and Jaffey does not adequately deal with the problem as it relates to his ‘value theory.’ He argues value cannot be duplicated or multiplied, but it does seem in this context that it is duplicated; it is causally in both parties’ estates. Jaffey does not suggest double recovery is an option, but there does seem an explanatory gap here.

3. Jaffey’s Wider Private Law Theory

This section relates to Jaffey’s wider views on private law, where his theoretical commitments cause Jaffey to take implausible positions about the trust. I look, in the first subsection, at the effect of Jaffey’s commitment to his principle of remedial consistency. I challenge the principle in a number of ways. It does not fit the law, which does provide a personal remedy against the trustee in the case of an invalid property transfer and historically did create a proprietary right in the beneficiary from personal rights against the trustee. Secondly, the principle is in theoretical terms too narrow. It should not in its own terms in fact require exact conformity to the original right in a remedy, and it amounts to a type of (discredited) sanction theory. The second subsection examines Jaffey’s claim that a historical understanding of the trust cannot help with the development of a principled explanation. The trust can in fact, contrary to Jaffey’s assertion, only be understood in terms of its development, and in particular the way equity strengthened the beneficiary’s rights against the trustee so much as to make them proprietary rights in the asset.

(A) Express Trusts and the Principle of Remedial Consistency

(i) Remedial Consistency and its Implications Explained

Jaffey describes the principle of remedial consistency as a logical, rather than a normative, principle, which means that it hides a remarkably strong claim that a remedy that does not fulfil the objective set out in the quotation below is not merely undesirable, but unintelligible.Footnote 112 Jaffey is clear that while he thinks remedies ought to follow this principle, he accepts that they do not always do so in current law.Footnote 113 Jaffey concedes that responses that do not meet this objective of fulfilling the original right are fineFootnote 114 so long as they are not called remedies, a concession which could render the principle an essentially toothless labelling point. Jaffey says,

[t]he objective of the remedy should be, so far as possible, to secure the claimant C the benefit of the primary relation … The remedy serves to correct an injustice, and this injustice is the injustice as defined by the primary relation. It is not open to the court to seek to remedy an injustice in any broader or unrelated sense.Footnote 115

The principle, also referred to as the ‘monist principle,’ requires that a remedy for a breach of duty be personal, as it cannot affect third parties, and that remedies to protect proprietary interests must themselves be proprietary. This is why there must be two dimensions to the trust. Breaches of the trustee’s duty to the beneficiary must have personal remedies only.Footnote 116 The proprietary remedy available to the beneficiary against third parties is not based on the breach of any duty,Footnote 117 but on the invalidity of the transfer. As Jaffey puts it, in the context of a claim by the trust beneficiary against the third party donee where the trustee has misapplied the assets,

[t]he beneficiary’s property right … persists and binds the recipient because beneficial ownership of the trust property was not validly transferred, and he (the recipient) is accordingly subject to an equitable proprietary claim, by which the beneficiary can enforce his property right in the trust property and recover it for the trust. The equitable proprietary claim arises from the invalidity of the transfer—from the fact that the transfer was not authorised under the trust.Footnote 118

This paper has already demonstrated that in the trusts context the principle breaks down. Since a beneficiary’s personal remedy following an account of administration in common form is not based on a proven breach of duty but on invalidity of the transfer, it should be a proprietary remedy. Jaffey’s view of the law does not fit how English and Canadian law actually works. It also does not accurately represent the way equity behaved in reifying (or part-reifying) obligations and providing proprietary remedies for what were historically personal rights, as seen later in this paper. There may be a parallel, but not identical, development in Scotland, where the third-party recipient as a constructive trustee holds the misapplied trust assets in a separate patrimony immune from their personal creditors, despite the insistence that the Scots trustee only owes personal obligations to the beneficiary.

(ii) Theoretical Problems with Remedial Consistency

There are wider theoretical issues with the principle as well as this practical issue of fit in the trusts context, which should make us question whether it should be a central idea in reasoning about private law generally, not just trusts. Essentially there are two (linked) problems. The first is that Jaffey appears to misunderstand the nature of a primary duty. It is not the case that the remedy is irreducibly linked to the duty so that it must replicate the effect of compliance with the duty. John Gardner put it well: an obligation is no more than a categorical mandatory reason to act in the sense that it acts to the exclusion of (at least some) other reasons.Footnote 119 Further, and this is worth quoting, “[t]hose who say they cannot detach the normative consequences because they are built into the very idea of mandatoriness have simply misunderstood the idea of mandatoriness.”Footnote 120 Gardner’s target here is the sanction theory of duties. Jaffey denies that his theory is a sanction theory, but it really is. Jaffey, reminiscent here of Gardner, argues that the sanction theory gives insufficient attention to the fact that a duty is simply a normative requirement directed at the actor. The sanction for Jaffey is merely additional.Footnote 121 But it is a wholly, completely, apparently logically non-detachable element of the package for Jaffey, and so while he is quite right, like Gardner, to point to independent normative reasons justifying the existence of a duty, he still falls foul of Gardner’s correct insistence that the normative consequences of a breach of duty are in fact logically detachable from the duty.

The second, and related, problem, is that the monist principle is, by its own lights, too narrow. The reasoning behind it does not support such a narrow conclusion as to what is acceptable. Even accepting per arguendo that the purpose of a remedy is to negate the effects of the breach or violation, to tie it in the standard case to factual replication of the fulfilment of the right is too narrow. Jaffey argues that because damages, and not specific performance, are the standard remedy for breach of contract, there is no Hohfeldian duty in contract cases,Footnote 122 but only a right-liability relation, which amounts to an allocation of risk of the other party’s reliance on the (non-forthcoming) performance. If there were a duty, specific performance, which more fully vindicates a Hohfeldian claim-right, would be the standard remedy. Jaffey does not say that damages are never appropriate, quite the contrary, but he insists that specific performance should be the standard remedy, bar where that is oppressive or pointless or where specific performance puts an additional burden on the defendant.Footnote 123 For Weinrib, however, who also maintains that his view of remedies is monistic,Footnote 124 a remedy’s purpose is to negate the negation of the claimant’s right.Footnote 125 This is rather opaque, but essentially Weinrib refers to the consequences of a breach as the wrongdoer having a normative gain and the victim a normative loss. It is this normative imbalance which should be corrected. For Jaffey to be right, that normative imbalance should only be corrected by directly forcing factual performance (unless it is oppressive). Weinrib’s corrective justice account shows that this is not right; the duty can typically be vindicated by money. Damages are a proper response, therefore, to breach of contract.Footnote 126 Of course once you have accepted that damages are sometimes acceptable to avert hardship on the defendant there is a slippery slope in terms of defining when that is so, which could bring Jaffey right back to defending the current law. If so, the principle seems to contribute little if anything to the debate. It becomes trivial.

(B) Normativity, Remedial Consistency, and Historical Development of the Trust

Jaffey ignores history, claiming that a historical understanding of the trust cannot explain it normatively.Footnote 127 Unconscionability is only relevant to a historical, as opposed to a principled, understanding of the trust, and historical and principled explanations are distinct. On one level this is perfectly reasonable. Doing legal history is not the same as doing law. However, there are two reasons to be sceptical; in fact, there are reasons to think that Jaffey is trying to have his theoretical cake and eat it. The first reason is that equity did do what Jaffey says must never be done. The second reason is that Jaffey must, in dividing the two approaches so completely, take a philosophically realist view of concepts at odds with his own espousal of Dworkin.

(i) Historical Development of the Trust

The first reason for scepticism is historical. Lionel Smith describes how the obligation that the feoffee of the land owed to the beneficiary of the use was gradually reified. Initially the third party had to actually interfere with the feoffee’s, later the trustee’s, obligations, but over time the requirement denatured as equity gave greater protection to the obligation.Footnote 128 Essentially by the end everyone bar equity’s darling was assumed to interfere with the trustee’s obligations. The process can be seen in the old case of Brook (Earl) v Bulkeley. Footnote 129 That case involved an obligation to renew a lease. A purchaser of an estate from a tenant in tail, with notice of the latter’s obligation to renew, was obliged to renew the lease. The development of restrictive covenants is similar although limited.Footnote 130 Despite a suggested general principle, the extension of liability to third parties with notice, such that they will be restrained in equity from inconsistent use of the asset, in The Strathcona Footnote 131 is again limited. There the time charterer of a ship was held to have an interest in the ship such as to bind a purchaser with notice of the charterparty. Nonetheless the point is simply that equity has been prepared, in appropriate cases, to make third parties liable and restrain them accordingly, if they have notice of the relevant obligations, and the language of constructive trust has been used to justify this.Footnote 132

Jaffey is quite right to say that any talk of interference by (say) a completely innocent donee is fictional and that there is a proprietary right in the beneficiary to exclude anyone bar a bona fide purchaser (or a thief) from the asset. That exclusionary right is the in rem part of the beneficiary’s rights.Footnote 133 However, what Smith’s theory illustrates is that the normativity ascribed to the beneficiary’s rights is inextricably bound to its history. In essence, equity reified the obligation. It did exactly what Jaffey claims is wholly impermissible, and the idea of a trust (or the restrictive covenant, and possibly The Strathcona) cannot be understood without recognition of this. It gave a remedy for a violation of, or interference with, a personal right and then denatured it to the extent that any violation needed no longer be proven. It made the beneficiary the owner of a property right in the obligation but, because the obligation always relates to particular assets, one that is indistinguishable from a proprietary right in the thing itself. The two cannot be separated, and it is in fact Jaffey’s insistence that they must be that demonstrates the ahistorical nature of his theory. His governing concepts and fundamental principles are delinked from past applications. His is a prescriptive approach,Footnote 134 stating what the law ought to be without charting a path from where the law is (and how it got there) to where it ought to be, which is how an interpretive approach would work.

(ii) Normativity

The second reason for scepticism is that Jaffey thinks he is not being prescriptive, but rather is being interpretive. He has subscribed to a Dworkinian view of law.Footnote 135 As is probably well known, Dworkin illustrates his theory by positing the existence of a hypothetical superhuman judge called Hercules,Footnote 136 attempting to find the right answer in the case before him.Footnote 137 Essentially for Dworkin a proposition of law will be true if the best justification of the practice provides a better explanation for that proposition than for any other.Footnote 138 Hercules uses two dimensions of interpretation. The first is fit, which asks how well the theory fits with the previously decided case law. The second is justification, which asks how good a theory it is in terms of the substantive political morality of the society.Footnote 139 Hercules tests his interpretation of any part of the law by asking whether it could form part of a coherent theory justifying the entire law.Footnote 140 This process of moving to a higher level of generality and testing theories for how they fit at that higher level is known as theoretical ascent.Footnote 141 Hercules then adjusts the theory and moves back to the lower level. The process is dynamic; interpretation is an interaction between interpreters and the practice itself.Footnote 142

Dworkin’s emphasis on fit and therefore with keeping faith with the past, and on developing the law by putting cases in the best possible light, makes his approach explicitly dynamic and developmental.Footnote 143 This dynamic dimension allows theorists to move the law in a direction that is more philosophically or morally justifiable, while remaining grounded in its past application.Footnote 144 Essentially, by interpreting past decisions and justifying them, judges work out what they think the law is, but having decided that this is the best view of the law, they are forced to say not only is this the law, but it always was the law.Footnote 145 Dworkin therefore takes what might be described as an anti-realist position about legal concepts. Consequently, it is unfair to see Dworkin as believing in Lord Reid’s Aladdin’s cave of law.Footnote 146 This can be contrasted with the realistFootnote 147 position where concepts are out there in the world. Some theorists, such as Beever and Rickett, adopt this view that norms are out there to be found.Footnote 148 Jaffey’s view that all categories of law should be justificatory and that all such categories must have a single normative justification unique to that category, which can be found without reference to history, equally suggests a static and geometric view of law where the concept is somehow ‘out there.’ The oddity is, as noted earlier, that Jaffey has in the past favoured a Dworkinian view of law,Footnote 149 but because of his insistence that history cannot assist with a principled explanation, ends up with a realist position on legal concepts, reflecting Hegelian Verstand.Footnote 150

Verstand is typically translated as ‘Understanding,’ and can be contrasted with Vernunft, or ‘Reason.’ Understanding is static and attempts to define the concept as an object separate from itself. Essentially, Verstand requires the criteria to be settled in advance; for Jaffey the concepts and categories are settled in advance. His mono-justificatory category map of the law is a fixed thing against which developments are measured. Jaffey is a philosophical realist in this sense. Vernunft does not require this. As answers given by courts shift, so the map of our categories shifts as well. Like Verstand, it is determinate, but in the sense that it is only once the reasoning process is complete that a person can know what comprises the concept. A Dworkinian and Hegelian view of legal concepts demands Vernunft, not Verstand.

For Hegel, conceptual content arises from the process of applying concepts; the determinate content of a concept is unintelligible apart from the process of development.Footnote 151 His theory of concepts is therefore a conceptual historyFootnote 152 and fits well with Dworkin, whose aspect of fit looks backwards and whose aspect of justification looks forward in a dynamic and developmental manner. Both Dworkin and Hegel hold that law is a seamless web which should seek to resolve any inconsistencies within itself, hence why Brooks puts both philosophers in the “interpretivist” camp.Footnote 153 Law’s normative content develops immanently; what is new in any determination of law’s normative content is only the implicit aspect of content not yet seen. For Hegel, the more explicit the determinations, the richer one’s understanding becomes and the closer to justice the law gets,Footnote 154 exposing a distinction with Dworkin, who denies that in his “one-world” view, justice and law are different.Footnote 155 For my purposes that is not so important. What is important is that if Jaffey wishes to keep fidelity to his espoused Dworkinianism, a more Hegelian view of legal concepts would suit him better and allow him to take historical developments such as Lionel Smith describes into account in his principled theory of trusts.

4. Fusion of Law and Equity

There are two strands to Jaffey’s argument on fusion. The first is a theoretical one based on the structure of his justificatory category system. Essentially Jaffey denies that equity is a justificatory category, and if it is not, it needs to be discarded. He argues that equity contains material drawn from different justificatory categories: primarily contract, tort, and property.Footnote 156 From this premise he suggests that equity is not a substantive category of law. At best, defenders of equity as a separate category have a remedial conception of it. Samuel Bray, for example, argues that equitable remedies should be treated differently because of their different functions.Footnote 157 For Jaffey this makes no sense. Equity is not a justificatory category. Analogical reasoning requires that one take the justificatory category, say of contract, and rationalise it to eliminate false differentiation based on the jurisdictional origin of the rules. That is all Jaffey means by substantive fusion. It is true, of course, that if all equitable doctrines are treated as somehow different purely by virtue of their jurisdictional origins, mistakes will be made.Footnote 158 Equitable duties of care are just as much duties of care as those in the tort of negligence, and where equitable and common law rules seek the same thing as for example in quantifying compensation for negligence, they should do so in the same way.Footnote 159 Yet it should be treated differently where there is a different type of claim in play; protecting an equitable interest is not the same as protecting possession.Footnote 160

So far Jaffey would not demur. He compares his discussion of equity with unjust enrichment. Substantive fusion aims to break up the spurious justificatory category of equity. Unjust enrichment theory creates such a spurious justificatory category.Footnote 161 Both unjust enrichment and equity draw on a range of different principles, but this is what one would expect in any sophisticated legal system. Despite Jaffey’s appeals to Dworkin, it is completely clear from Law’s Empire Footnote 162 that Hercules is not interested in the type of sharp-edged mono-justificatory categories that Jaffey works with. Hercules believes that different principles have different weights across the whole spread of private law. Dworkin would never say that the only principled categories are those that fit within Jaffey’s purist view of doctrinal category. There is no reason why an idea such as equity that draws together features of the law that may be unrelated to the justification of a claim, but might relate to the remedy, should not provide cross-cutting principles. Jaffey’s second point is related to this. Since the labelling of a right as legal or equitable refers only to a defunct procedural division in its enforcement, it has ceased to matter.Footnote 163 In the trusts context Jaffey argues that his division between control and benefit was obscured by that (now obsolete) procedure. One answer is that his project is reconstructionist; he says explicitly that the trust can only be properly understood once dissociated from its historical origins,Footnote 164 the exact opposite of what is argued by this paper.

Jaffey can be read as making a more sophisticated claim about conceptual change. The abolition of the procedural division in the enforcement of legal or equitable rights to which he refers allowed for an interpretive development of the concept of the trust. On the view of law and concepts espoused in this article, it is the differing possible inferences that can be made in any particular case that allow for conceptual change. If several possible interpretations are open to judges, then when they make a choice, that choice concretises the concept. Such change also occurs when normative notions that previously constrained decisions begin to lose their grip and are experienced with weakening authority. This might be, as it is often in the common law, because of a new problematic case, although Pippin puts it wider than this, suggesting that the notion and nature of normative authority can equally be up for grabs in the extreme case.Footnote 165 Jaffey’s view can only really be defended on the basis of a radical revolution post Judicature Acts, where, in a loose analogy with Thomas Kuhn’s distinction between normal and revolutionary science, one paradigm is completely replaced by another.Footnote 166 In other words, what happens is that the administrative fusion of the courts of Chancery, Queens Bench, and Common Pleas into one abolished a procedure, and by doing that enabled the law to reconstruct the trust around the two dimensions.

The original argument had a huge leap in it. In an appendix to The Nature and Scope of Restitution, Jaffey argued that removing the relevance of whether the right derived from the Chancery Court in itself removed the relevance of whether it is equitable or legal.Footnote 167 If that were right, there would indeed have been a Kuhnian revolution. The jump is too great, however. Substantive differences in the law remain, and further argument is needed. Jaffey provided some of that extra argument in his second book, but the point remains unproven. To prove the point conclusively Jaffey would need to show that fusion has removed all need to look to past arguments. He has not done this.

Jaffey’s argument in his second book is mainly aimed at the procedural fusionist position that equity has a distinct methodology, but in fact does not entirely succeed in countering the position. He suggests, for example, that equity does not systematically prefer discretion over rules.Footnote 168 He argues that it cannot be a justificatory category without the unique underpinning that exists, say in contract law. He argues that unconscionability cannot perform that function as it is at best a statement that there is wrongdoing, a type of modality.Footnote 169

Henry Smith, however, provides important potential counter-arguments, although Jaffey is not Smith’s target. In a range of important contributions, Henry Smith suggests equity provides many of these substantive contributions to the law by providing a second order safety valve,Footnote 170 which he now describes as meta-law.Footnote 171 Originally, Smith argued equity responds to problems of opportunism. He described opportunism as being behaviour technically legal but which in fact tries to extract unintended benefits from a position and often imposes disproportionate costs in doing so.Footnote 172 He has since added issues of multi-polarity, polycentricity, and conflicting rights. Polycentric problems involve many items, people, and ideas which are interdependent in their connections, and such are said to pervade equity.Footnote 173 Equity as meta-law is well suited to competing or conflicting rights. One solution, Smith argues, is to define them better ex ante, but equity instead reconciles them ex post in a more context-sensitive manner.Footnote 174 With regard to opportunism, because it is difficult to detect and define and rule against in an ex ante fashion, equity acts ex post, as for instance in fiduciary duties, but because of the potentially over-expansive nature of such an open-ended ex post jurisdiction, it steps in only when certain factors are triggered, such as bad faith or disproportionate costs and burdens.Footnote 175 The trustee on this view has obligations to the beneficiary precisely because there is the potential for opportunism built into their ability to use and manage legal title.Footnote 176 The burden of proof in the obligation of stewardship is effectively reversed. The beneficiary need not prove a breach; they need only to ask for an account of what happened and demand that anything missing be replaced. This, and associated fiduciary obligations, precludes opportunism and responds effectively to vulnerability in the person of the beneficiary. For Smith, therefore, the safety valve is a second order module, linked to the law by particular interactions. Smith goes further, suggesting that not only is this what functional equity ought to have from a normative standpoint, but that historically Chancery judges have attempted explicitly to do precisely this, referring to their role in preventing fraud or ‘equitable fraud’ in relation to section 53(1)(b), Law of Property Act 1925 (UK), or secret trusts.Footnote 177

Jaffey has rejected this line of argument, although not discussing Smith directly. He suggests that it amounts to a two-stage legal reasoning process, in which a reasoner first decides what the party is allowed to do at law and then modifies that according to a set of principles based on a different method of adjudication or regulation.Footnote 178 Jaffey questions whether that is sensible. First, Smith would agree that it is two-stage, but he argues that the two-stage nature of equity is essential. It is essential because it reduces complexity and uncertainty. He notes that the only way to reduce this to a first order matter is to generate combinations of standards and multi-factorial discretions at law in much the way that American law has. He provides the example of nuisance, which involves assessments of the social value of both the plaintiff’s and the defendant’s use or actions.Footnote 179 This undermines the rule of law in ways equity currently does notFootnote 180 by allowing context free rein without the discipline of restricting it to the equitable points of contactFootnote 181 with the law. By restricting equity and making use of it as a higher order meta-law, it is possible to handle complexity, polycentricity, and interdependence better. By correcting problems from outside, equity allows the common law to be more general and more predictable.Footnote 182

Paul Miller has made the important point that equitable intervention might simply be because it is better at supplementing or adding to the law if the common law were slow to innovate.Footnote 183 It may even be that in some cases, where the action can be easily defined and delineated, that it crosses the line to being common law and tortious.Footnote 184 For Henry Smith, much of equity has a distinct function, one which is not captured effectively by Jaffey’s hermetically sealed justificatory boxes. Indeed, by its very nature, Smith’s second-order equitable function, equity as meta-law, supplements the first order law in a way that is superior to other solutions. Equity’s intervention is not as a doctrinal justificatory category but as a cross-cutting principle, the existence of which cannot be thought surprising on a Dworkinian view. It may be, of course, that opportunism cannot explain all of jurisdictional equity. Functional equity and jurisdictional equity need not coincide, and this might allow slippage of areas into common law.Footnote 185 Breach of confidence (or parts of it) have slipped into common law misuse of private information. The function that Smith claims for equity survived the abolition of the court of Chancery.

5. Conclusion

This paper has sought to explain flaws in Jaffey’s theory of the trust as well as some flaws in his wider private law theory, illustrated by the way it applies to the trust. The paper sought in Part 2 to expose the inadequacies of Jaffey’s failure to recognise the importance of trustee knowledge (as opposed to consent) and the radicalism of his views on ownership of value. It suggested, in Part 3, first that Jaffey’s monist principle does not fit English trusts law and amounts to a discredited sanction theory. Secondly, Part 3 argued that Jaffey’s view that history cannot assist in understanding the trust is unDworkinian. An interpretivist view of the law, and Jaffey maintains that he is an interpretivist, must be faithful to both its history and moral justification. A legal concept can therefore only be understood in the context of its conceptual history and, in our context, that conceptual history can only be understood in terms of the purpose behind the development of the trust and historical understandings of the distinctive contribution of equity. The paper finally exposed, in Part 4, how Jaffey’s views on fusion are unsupported.
