This article argues that all-affected principle needs to be reconceptualized to account for the differences in the historical and current social position of those who are or who should be making legitimacy claims. Drawing on Butler’s theory of vulnerability, this article advances a new and more robust all-affected principle that affords a stronger claim to legitimacy to those most-deeply affected by both the current decision in question and the historical process and practices shaping the choices available. In particular, this article (...) identifies three sets of exclusions of groups and claims that drive this reformulation: first, cases of historical injustice such as indigenous peoples; second, cases of current processes of minoritization which silence or render some groups and opinions as marginal such as women, ethnic minorities or even people in lower economic classes; and third, cases of state establishment of boundaries and ‘worthy’ citizenship such as refugees making claims for relocation and asylum.
