Lon Fuller’s fictional Purple Shirt regime, Victor Orbán’s illiberal democracy in today’s Hungary and the Kaczynski brothers’ recently ended unconstitutional republic of Poland are three examples of a ‘broken democratic polity’ in which many aspects of the rule of law and constitutional democracy have been compromised and cannot be fixed without a qualified majority, even if democratic forces come to power. In this article, I address the question of whether illegal state action of a democratic government is an appropriate means of restoring legitimacy to what I call a ‘broken’ polity. Put differently: Is it morally defensible for a new democratically elected government to override and replace the rules of illiberal constitutional reform in violation of formal legality? If so, under what conditions? I argue that a positive answer to this question is justified if we adopt a neo-republican approach to politics and legitimacy.
