Ian Borrin Lecture 2025
The 2025 Ian Borrin Lecture was delivered by Professor Rosalind Dixon, Anthony Mason Professor and Scientia Professor of Law and Director of the Gilbert + Tobin Centre of Public Law at UNSW Sydney.
It is now widely understood that constitutions are interpreted and enforced by a wide range of actors—not simply courts. Moreover, different actors bring a variety of approaches and perspectives to bear in this process of interpretation. And much of constitutional theory has come to embrace this form of (what Professor Dixon calls) “constitutional polyvocality”, or the idea of “polyvocal constitutionalism”.
In her lecture, Professor Dixon explored different understandings of the idea of polyvocal constitutionalism, and how this thinking helps to understand and situate a range of new works in comparative constitutional theory. She also highlighted the strengths, and weaknesses, of these different theories, especially their capacity to respond to the current political moment—in which many previously stable democracies are seeing widespread forms of “abusive” constitutional change.
