This paper explores the complex iteration of ethnic identity and legal culture amongst the Chakma peoples of the Chittagong Hill Tracts of Bangladesh and the hill territories of Tripura, India. Its hypothesis is that the stigma of tribal identity is more likely to be sustained in situations of ‘weak’ pluralism – that is, where the customary system is formally annexed to the state. However, such stigma is more likely to be dispelled where numerous, competing legal jurisdictions collide in a ‘strong’ pluralism expressed as a relatively autonomous legal domain, overlapping legal jurisdictions and in the presence of a productive and potentially creative ‘interlegality’. Conversely, strong state recognition of identities, such as can be found in India, appears to be linked to weak local pluralism, creating an insular and inward-looking community that embraces stigma and the preservation and use of customary practices. In conclusion, this paper asserts that formal state recognition in a situation of legal pluralism tends to freeze identities in a facsimile of the colonial trope of tribe, whilst conflict between the communities and the state generates new and resistant identities and new iterations of customary law.
