This paper agrees with Walker on the existence of a tension between democracy and constitutionalism, but questions whether democracy and (international) constitutionalism necessarily depend on each other. While democracy needs constitutionalism on normative grounds, as an empirical matter it may also rest on alternative political structures. Moreover, it is questionable whether democracy is indeed the solution to the incompleteness of international constitutionalism. Traditional forms of democracy do not lend themselves well to transplantation to the international level and could even intensify some problems of international governance. Attempts to democratize international relations should be carried out prudentially, with due regard for possible counterproductive effects.
