What does it mean to make a region? What is a region in a world dominated by the model of the sovereign nation-state? And what does a newly established court of law have to do with this? In this talk, Lee Cabatingan begins to address these questions through a discussion of her recently published book, A Region among States: Law and Nonsovereignty in the Caribbean (Univ of Chicago Press, 2023). Based on long-term ethnographic research at the Caribbean Court of Justice, headquartered in Trinidad and Tobago, Cabatingan offers her analysis of the region-making work of this legal tribunal, arguing that the Court “cites to” but does not mimic familiar nation- and state-making techniques. That is, the Court, like much of the postcolonial Global South, walks a fine line between making the region a legible and legitimate entity (by utilizing classic tools of nation-state building, for example) and creating a polity that is better suited to the needs of the small island states of the Caribbean (by refusing sovereignty, for instance). Throughout her talk, Cabatingan also provides insight into how she conducted her ethnographic research, important considerations of her positionality in the field, the development of her arguments, her ethical commitments, and the process of writing the book.
