An often overlooked tension in liberal theory turns on its commitment to procedural accounts of legitimacy on the one hand, and to the robust protection of the right of citizens to dissent on the other. To the extent that one evaluates legitimate decision-making on the basis of the procedures that bear on it, determining how extra-procedural expressions of dissent fit into the picture becomes a complex undertaking. This is especially true if one accepts that protecting extra-procedural expressions of dissent is (...) itself foundational to the overall legitimacy of the state. My aim in this paper is to explore some of the implications that follow from this tension. The paper proceeds in two parts. In the first part, I review the political grounds that support a protection on dissent. By drawing on its republican foundations, I argue that the functional role that the right to dissent serves in complex political communities is intimately connected to concerns over legitimacy. I claim that for the right to perform its function successfully, protections must be placed on both procedural and extra-procedural forms of dissent. The second part of the paper issues a direct challenge to procedural accounts of legitimacy. If a protection on citizen dissent is vital to legitimating government action, and if that protection necessarily extends to both procedural and extra-procedural forms of dissent, it follows that legitimacy cannot be captured by procedure alone—even procedures that secure the fair and equal participation by all affected parties.
