In this article, we argue that the 2022 Chilean draft Constitution helps to articulate the distinction between a transformative constitutional project and a utopian one. Whereas a transformative project lays down markers for social change that will take time to achieve, a utopian project sets out goals that are unlikely to be achieved within any reasonable timeframe. Utopianism is a product of two relationships. The first is the internal relationship between the transformative goals laid out in a constitution and the institutional pathways through which changes will occur. The second is the external relationship between the goals in the text and the views and support of key groups. In Chile, both relationships were problematic. First, the Convention adopted a draft that was heavy on ambitious programmatic content but lacked a clear vision of how to implement it. Second, the Convention produced a draft that was supported by the ephemeral civil society groups galvanized by the 2019 protests but divorced from the vision of Chile’s parties and public opinion. Some of this was a product of the peculiar electoral context in which the Convention acted, which has already been corrected. But some of it reflects deeper tensions within transformative constitutionalism.
