Citizenship practices in the Indian state of Assam have a serious fault line. The government appears uninterested in policing borders and enforcing the citizen/alien distinction. This has drawn the ire of even the Indian Supreme Court. Certain ambiguities about citizenship in post-Partition India explain these practices. Pragmatic politicians have adapted to the reality of a post-Partition space that does not conform to the idealized notion of a bounded national territory with a clearly defined community of citizens. However, the tensions between ‘the national order of things’ and the reality of a non-national space have consequences: they adversely affect governmental legitimacy. Policies premised on the fiction of hard national borders that are fundamentally at odds with ground realities cannot provide the foundation for a stable legitimate political order.
