 Will theorists maintain that a right makes the rightholder “a small scale sovereign” (Hart 1982, 183). More specifically, a will theorist asserts that the function of a right is to give its holder control over another’s duty. Your property right diagrammed in the figure above is a right, says the will theorist, because it contains a power to waive (or annul, or transfer) others’ duties. You are the “sovereign” of your computer, in that you may permit others to touch it or not at your discretion. Similarly a promisee is “sovereign” over the action of the promisor: a promisee has a right because she has the power to waive (or annul) the promisor’s duty to keep the promise. In Hohfeldian terms, will theorists assert that every right includes a Hohfeldian power over a claim. In colloquial terms, will theorists believe that all rights confer control over others’ duties to act in particular ways.
