The rule in Re Hastings-Bass is an equitable control on the exercise of powers by trustees. It has developed without satisfactory explanation of its doctrinal basis, resulting in uncertainty as to its scope and application. In Pitt v Holt [2011] EWCA Civ 197 the Court of Appeal began to remedy these defects by deciding that the rule is founded on a trustee’s duty properly to consider the exercise of a power. This thesis argues, first, that Pitt is right to understand the Re Hastings-Bass rule as premised on the duties of trustees, and not on the exercise of a power producing an unintended result. This accords with the reasoning of earlier cases on the rule, and is also consistent with House of Lords authority on fiduciary powers and judicial non-interference in trustees’ decision-making. This duty is not a ‘fiduciary’ duty, or an aspect of the trustee’s duty of care, but is an independent incident of the office of trustee. Secondly, this analysis of the Re Hastings-Bass rule facilitates exposition of its important features: the concept of ‘relevant consideration’ must be carefully circumscribed; the purported exercise of a power in breach of the rule is voidable, not void; the rule does not apply to purely personal powers, or to administrative powers; there are no special rules for pension trusts or the use of the rule to mitigate liability to taxation; trustees can usually avoid a breach of duty by taking professional advice; and in some circumstances, those professional advisers can incur liability to the trust beneficiaries. Finally, the relationship between the Re Hastings-Bass rule and fraud on a power is examined. It is argued that the analogy between the two doctrines is not sound, and that there is reason to doubt aspects of the orthodox account of fraud on a power.

The rapid expansion of the Chinese economy has made China aware if the importance of the rule by law. Perfecting its legal system and expanding its economy are the two goals of modern China. Many laws and regulations have been enacted since the economic reform was launched at the end of 1970s. The enactment of the Chinese Law of Trusts is an important step in the refinement of the Chinese legal system.This thesis aims to identify the deficiencies in the Chinese Law of Trusts by giving a critical and comparative study of the Australian and the Chinese trusts law, so as to propose amendments to the Chinese Law of Trusts. This thesis is divided into two Parts, and seven Chapters. Part One, which comprises five chapters, is a comparative study of the Australian and the Chinese trusts law. It also discusses the laws of trusts in other important Common Law and Civil Law jurisdictions. Chapter 1 of this Part deals with the basic concept of the trust. It introduces and discusses the definition, and the characteristics of the trust, the comparison between the trust and other similar concepts, and the classification of trusts. Chapter 2 deals with the creation of express trusts. With respect to the rights and duties of the trust parties, Chapter 3 gives a detailed discussion. Chapter 4 examines the variation and termination of trusts. The last chapter of Part One, Chapter 5, specifically analyses the charitable trusts.Part Two comprises two chapters: Chapter 6 and Chapter 7. Chapter 6 discusses the practical impact of the Chinese Law of Trusts on the Chinese State-owned enterprise reform, which has been progressing for more than two decades in China. Chapter 7 is a general concluding chapter. It pinpoints the deficiencies in the Chinese Law of Trusts, analyses the reasons for the deficiencies, and suggests two solutions to improve the Law: namely, to improve the existing provisions of the Law and to adopt eclectically the elaborate concepts of the Australian law of trusts.

The central tenet of tracing theory is that in certain circumstances it is possible to show that one asset stands in the place of another, such that any claims in relation to the original asset can be transmitted to its substitute. Since at least 2001 academic and judicial orthodoxy has been that this is done by following the path of value from one asset to the other, and can be aided in more complex cases by the application of evidential rules or presumptions. These ideas are at the heart of existing accounts of proprietary claims against trustees who deal with trust assets without authority, and personal and proprietary claims against strangers to the trust. They are also at the heart of calls to 'unify' the rules of tracing at law and in equity, removing existing distinctions drawn between claimants who are owed fiduciary duties and those who are not. In this thesis it is argued that there are no independent processes of following and identifying value, and that the language of 'tracing value' has lent the appearance of neutrality and conceptual unity to disparate heads of fiduciary and non-fiduciary liability. Most importantly, it has led to the assumption that in any case in which a claimant can demonstrate that a series of transactions links some right in the defendant’s hands with a right previously held by or for the claimant, the claimant can claim that right. In this thesis it is argued that far from creating an arbitrary practical obstacle for claimants seeking to trace and locate value, the fiduciary relationship is at the heart of the justification for any claim that exists to a new right in the hands of someone else.

This thesis examines various aspects of English and Canadian charity law in terms of their relationship with the contested categories of ‘public law’ and ‘private law’. It argues that the law of charities can be regarded as a hybrid legal discipline in both a general or categorical sense, and in the context-specific or functional sense that both the conditions for obtaining charitable status, and the regulation of the conduct of charities and their trustees, are continually being adjusted in such a way as to maintain in a broad sense a functional equilibrium between individual project pursuit and collective project pursuit; that is to say, an equilibrium between the protection of the autonomy of property-owning individuals to control and direct their own wealth, and the furtherance of competing public interests or visions of the good. After sketching out the history and nature of the common law charities tradition and the contemporary English and Canadian regulatory regimes, the thesis pursues its analytical and comparative hypotheses by examining two important features of English and Canadian charity law, the public benefit doctrine and the rules of locus standi that determine who may seek relief for misapplications of charity property. It then addresses the comparatively modern issue of the governmental co-optation of charitable resources, considering to what extent modern pressures associated with the retrenchment of welfare states threaten to destabilize charity law’s hybrid equilibrium in EW and Canada. The thesis then turns to the emerging phenomenon of social enterprise, arguing that shifts to charity law’s functional equilibrium may explain the emergence of this ‘post-charitable’ legal form. The thesis concludes with some observations on the hybrid nature of the law of charities, and on the different functional equilibriums between individual project pursuit and collective project pursuit that have been reached by English and Canadian charity law.

This thesis presents an account of attribution in unjust enrichment. Attribution refers to how and when two parties – a claimant and a defendant – are relevantly connected to each other for unjust enrichment purposes. It is reflected in the familiar expression that a defendant be 'enriched at the claimant's expense'. This thesis presents a structured account of attribution, consisting of two requirements: first, the identification of an enrichment to the defendant and a loss to the claimant; and, secondly, the identification of a connection between that enrichment and that loss. These two requirements must be kept separate from other considerations often subsumed within the expression 'enrichment at the claimant's expense' which in truth have nothing to do with attribution, and which instead qualify unjust enrichment liability for reasons that should be analysed in their own terms. The structure of attribution so presented fits a normative account of unjust enrichment based upon each party's exchange capacities. A defendant is enriched when he receives something that he has not paid for under prevailing market conditions, while a claimant suffers a loss when he loses the opportunity to charge for something under the same conditions. A counterfactual test – asking whether enrichment and loss arise 'but for' each other – provides the best generalisation for testing whether enrichment and loss are connected, thereby satisfying the requirements of attribution in unjust enrichment. The law is stated as at 15 March 2014.

This thesis brings together two responses to the question ‘how can the law extend the timeframe for environmentally relevant decision-making?’ The first response is drawn from the context of institutional investment, and addresses the timeframe and breadth of environmental considerations in pension fund investment decision-making. The second response is related to the context of public environmental decision-making by legislators, the judiciary, and administrators. Three themes underlie and bind the thesis: the challenges to decision-making posed by the particular temporal and spatial characteristics of environmental problems, the existence and effects of short-termism in a variety of contexts, and the legal notion of the trust as a means for analysing and addressing problems of a long-term or intergenerational nature. These themes are borne out in each of the four substantive chapters. Chapter III sets out to demonstrate the theoretical potential of pension funds to drive the reduction of firms’ environmental impact, and, focusing particularly on the notion of fiduciary duty, explores the barriers that stand in their way. Chapter IV provides a practical application of the theoretical recommendations outlined in its predecessor. It provides a framework outlining how pension funds might implement a longer term, more sustainable approach to investing. The second half of the thesis, operating in the context of public environmental decision-making, is centred upon a particularly poignant legal notion with respect to the environment and time: the concept of intergenerational equity. Just as the first half of the thesis deals with the timeframes relevant to investment decision-making by pension funds within the bounds of fiduciary duty, largely a private law affair with public implications, the second half of the thesis is concerned with the principle of intergenerational equity as a means for extending the decision-making timeframe of legislative, judicial and administrative decision-makers. As previous analyses of the concept of intergenerational equity provide little insight into its practical implications when applied to particular factual situation, Chapter V sets out the structure of the principle of intergenerational equity as revealed by case law. Chapter VI brings together the issues from the first three papers by conceptualising intergenerational equity in resource management as an issue of long-term investment. Long-term environmental decision-making faces many obstacles. Individual behavioural biases, short-term financial incentive structures, the myopic pressures of the electoral cycle and the tendency of the common law to reinforce the (often shorttermist) status quo all present significant barriers to the capacity of both private and public decision-makers to act in ways that favour the longer term interests of the environment. Nonetheless, this thesis argues that there is reason for hope: drawing upon the three themes that underlie all of the substantive Chapters, it articulates potential legislative changes and recommends the adoption of particular governance structures to overcome barriers to long-term environmental decision-making.
