The Functions of Rights
Abstract
On the basis of a Hohfeldian analysis of rights, Leif Wenar explains how rights perform six distinct functions. He then argues that his several function theory is preferable to the single function will and interest theories of rights. But in his description of the theories of H. L. A. Hart and Neil MacCormick, he fails to distinguish between essential and non-essential functions. When these are considered, neither is a single function theory. And an ambiguity in Wenar’s descriptions of the functions of rights suggests the distinction between inherent and instrumental functions. This distinction reveals an additional complexity in the theories of Hart, MacCormick, Feinberg and Raz, among others. Therefore, any adequate theory of the functions of rights must recognize the currently ignored distinctions between essential and nonessential functions and between inherent and instrumental functions.
