This article offers a critical discussion of two influential positions in contemporary legal and political theory, which will be referred to as ‘political constitutionalism’ and ‘strong popular sovereignty’. Despite their important differences, both share a sceptical approach to the dominant constitutional practice in liberal democracies, hence they are brought together here under the term ‘weak constitutionalism’. They both highlight the political dimension of the constitution, arguing that democratic legitimacy requires institutional arrangements that give the people and/or their representatives the last word in settling fundamental issues of political morality. By contrast, this article underlines the legal dimension of the constitution as the repository of the moral principles that make possible a practice of public justification in constitutional states. It is from this second constitutional dimension that the critical arguments are developed, both against the desire to take the constitution away from the courts and the aspiration to recognize the constituent power as pre-legal constitution-making faculty.

International institutions underpinning the ‘liberal international order’ are increasingly contested by established Western powers. This article contributes to a better understanding of this novel challenge ‘from within’. We conceptualize four types of contestation frames according to (1) whether contesting states attribute the source of grievances to specific practices or the underlying principles of an international institution; and (2) whether they present their own nation or the international community as the subject of grievances. Combining these two dimensions, we distinguish between globalist-reformist, nationalist-reformist, globalist-revisionist and nationalist-revisionist contestation frames. These contestation frames are consequential as they open up or shrink the discursive space for contested institutions’ re-legitimation. Drawing on the Trump Administration’s contestation of the World Bank, NATO, the UNHRC, and the WTO, we demonstrate that contestation frames and defenders’ responses varied greatly across institutions, ranging from accommodative deliberations about institutional reforms to principled rejection and the justification of the status quo.

The notion of legal space is increasingly being used to address the challenges of multiple and overlapping spheres of legality that the notion of legal order cannot capture. This article shows how legal space can serve as an alternative (or at least complementary) concept to legal order in view of the limitations of the latter. It sketches out a notion of legal space that is inspired by topology, an approach that analyses the qualitative nature of spaces. It is concerned with understanding the ways in which legalities interact, rather than with ‘measuring’ their spatial dimensions. A topology-inspired approach to legal space can contribute to conceptualizing, in a novel manner, the inner structure of legal spaces, the boundaries of these spaces and their interrelations with other spaces. It offers an analytical toolkit for better understanding multiple legalities, providing categories to characterize sets of legal elements as well as phenomena such as overlaps and hybridity. It is conceptually less constrained than the concept of legal order, and thus allows us to address various bodies of law ranging from classical domestic law, EU law and international law to global administrative law, corporate social responsibility law, platform law and lex sportiva.

This article adds nuance to current understandings of the relationship between the populist leader and the public by using the concept of trust. Merging the literature on populism with the growing scholarship on trust from philosophy, psychology and other social sciences, it argues that following on from the populist leader’s appeals to similarity, the populist–public relationship involves an intertwining of two forms of public trust: the public’s trust in the populist and the public’s trust in itself (what we term ‘public self-trust’). Contrary to what political and constitutional theorists have recognized as a tension between public self-trust and the public’s trust in its political representatives, we contend based on the scholarship on trust that in the populist–public relationship these two forms of trust can be mutually reinforcing. This mutual reinforcement, we suggest, has the potential to create a positive feedback loop of public trust that, given the value of public trust to political leaders, empowers the populist.
