This chapter shows that a remedial conception of equity is incomplete, at least in the forms that cast its aim as enjoining opportunists and those who are sticklers for their rights in a bad way. Along with its anti-opportunist domain, equity has a jurisdictional sphere. In its jurisdictional sphere, equity’s concern is determining the rightful scope and exercise of other-regarding powers. An opportunist or a sticker in a bad way is just someone who has abused an other-regarding power. In this respect, equity and its doctrines exhibit a number of striking parallels with the jurisdiction and doctrines of administrative law. From this, the chapter then draws two conclusions. First, both domains express jurisdictional justice. Second, is either closely related to public law, or is really just a branch of public law. This second lesson explains a number of distinctive features of equity, for example its second-order structure, its historical deployment of the concept of conscience, and the characteristic properties of Equitable remedies.
