"The workshop will study the politically salient, yet normatively undertheorized, widespread practice of granting denizens (i.e., ‘non-citizen residents’, ‘resident aliens’) fewer/different political, social-economic, and cultural rights than citizens. How should we theorize practices of legal rights-differentiation? What is the appropriate moral framework for making sense of diverging legal entitlements between citizens and denizens? By reflecting on the concept and possible normative grounds of rights-differentiation, the workshop aims to make real progress on the question of whether priority for citizens in terms of political, socio-economic, and language rights is ever morally justified."
