Abstract

How should the fact of state consent to international agreements affect their moral evaluation? Political criticism of the content of international agreements is often answered by invoking the voluntary nature of those agreements: if states did not wish to accept their terms then they were free to reject them; the fact of their having voluntarily accepted them limits the scope for subsequent criticism. This is the “Voluntarist Reply”. This paper examines the Voluntarist Reply to understand the specific moral work that it claims to do, the sense of voluntariness that it requires, and the limits on the capacity of voluntary consent to answer substantive political and moral criticism . It maps those limits across four prominent and plausible accounts of international economic justice to understand the different ways that consent does or does not alter the moral situation.
