Hans Kelsen refused to develop a democratic theory of the basic norm. Given that he expounded a strong distinction between law and politics as two separate scientific disciplines he consistently argued against any attempt to politicize legal science and corrupt its object of cognition. As a result, there has been very little discussion of the basic norm in relation to his democratic theory. This article attempts to fill this gap by tracing the relationship between the basic norm and democracy in Kelsen’s legal and political writings. More precisely, it maps Kelsen’s seminal distinction between autonomy and heteronomy onto his reflections on constitutional making and probes the anti-democratic implications of his theory of the basic norm as they undermine the normative foundations of democratic theory. The article concludes by addressing the question of whether it is possible to articulate a theory of the democratic ground norm, of democratic foundings with a normative content, by proposing the idea of an immanent, performative basic norm as the source of validity of a democratic constitutional order.
