Abstract

In this paper I argue that something has gone wrong with the law of restitution for unjust enrichment. I aim to explain what I think has gone wrong, and to propose the beginning of a solution. I argue that scholars and courts have equivocated between seeing unjust enrichment as a cause of action, which can be applied directly to the facts to determine whether a defendant is liable, and seeing it as a principle, whose role is only to say something about a field of law. Many of the arguments that have been made over the last thirty years presuppose that unjust enrichment operates as a cause of action, even though they do not say so expressly. I argue that it cannot be a cause of action, which undermines a great deal of the scholarship and which means, in turn, that the causes of action remain to be described. The second part of the paper begins that task.
