Fiduciary Law as Equity’s Child

Abstract

This chapter challenges the argument that one of Equity’s most distinctive doctrines, fiduciary law, must be fused with a common law doctrine—the law of contract. In particular, it highlights the disadvantages of transforming the equitable duty of loyalty into an ordinary contractual obligation. The chapter first considers the ‘contractarian’ interpretation of fiduciary law according to which fiduciary duties are no more than a species of contractual obligations before explaining why, in contrast with the contractarian argument, Equity was right in claiming that the fiduciary relationship was essentially different from contract. After making the case of why fiduciary law should be treated as a sui generis equitable doctrine, the chapter examines two features of equitable fiduciary law that will change dramatically if the fusion suggestion is adopted (the language in which it is set and the way into the relationship) and shows the adverse consequences of moving in that direction. It concludes with the contention that the concept of ‘conscience’ still has an active role to play in the legal reasoning about fiduciaries.
