258Between openness and resilience: rethinking citizenship in times of polycrisisEthics and Global Politics. 2026.Under present conditions of multiple, overlapping, and mutually reinforcing crises, both the internal and external dimensions of citizenship have come under pressure. Externally, higher migration flows, growing multiculturalism, and the commodification of transnational belonging make it increasingly difficult – both morally and politically – to sustain hard boundaries between insiders and outsiders. Internally, democratic backsliding and the increasingly oligarchic character of contemporary soci…Read more

342Beyond Myth Busting: How Engagement with Ethical Dilemmas Can Improve Debates and Policymaking on MigrationEthics and International Affairs 39 (1): 26-36. 2025.Many aspects of migration policy involve hard moral dilemmas. Whether the dilemmas are concerned with refugee accommodation and integration, temporary labor migration, or the prospects of rejected asylum seekers, policymakers must sometimes make tough choices between competing and equally compelling moral values. Through in-depth discussion of various concrete examples, contributions to this roundtable argue that recognition and systematic analysis of the “ethics of migration policy dilemmas” ca…Read more

724Debating responses to unauthorised immigrant residence (edited book)EUI Working Paper. 2024.This working paper combines Lukas Schmid’s article “Responding to unauthorized residence: on a dilemma between ‘firewalls’ and ‘regularisations’” with three critical responses as well as a rejoinder by the author. Schmid argues that a set of liberal-democratic commitments gives conscientious policymakers strong reason to implement both so-called ‘firewall’ and ‘regularisation’ policies, thereby protecting unauthorised immigrants’ basic needs and interests and officially incorporating many of the…Read more

556Is Legitimate Exclusion Incompatible with the Sovereign Right to Exclude?AJIL Unbound 118 219-223. 2024.Scholars of international law have been increasingly troubled by states’ vast powers and practices of migrant exclusion. There is no doubt that much of this uneasiness is catalyzed by a keen sense of the demands of a basic liberalism at the international legal order's core. Indeed, the increased construction of border walls,1 the continuously widespread use of deportation as a migration control tool,2 and new digital bordering technologies3 have all come under scrutiny precisely because of the c…Read more

700Responding to unauthorized residence: on a dilemma between ‘firewalls’ and ‘regularizations’Comparative Migration Studies 12 (22): 1-18. 2024.Residence of unauthorized immigrants is a stable feature of the Global North’s liberal democracies. This article asks how liberal-democratic policymakers should respond to this phenomenon, assuming both that states have incontrovertible rights and interests to assert control over immigration and that unauthorized residence is nevertheless an entrenched fact. It argues that a set of liberal-democratic commitments gives policymakers strong reason to implement both so-called ‘firewall’ and ‘regular…Read more

1203Colonial injustice, legitimate authority, and immigration controlEuropean Journal of Political Theory (1): 4-26. 2023.There is lively debate on the question if states have legitimate authority to enforce the exclusion of (would-be) immigrants. Against common belief, I argue that even non- cosmopolitan liberals have strong reason to be sceptical of much contemporary border authority. To do so, I first establish that for liberals, broadly defined, a state can only hold legitimate authority over persons whose moral equality it is not engaged in undermining. I then reconstruct empirical cases from the sphere of int…Read more

1212Freedom‐amelioration, transformative change, and emancipatory ordersEuropean Journal of Philosophy 30 (4): 1378-1392. 2022.Abstract“Freedom” is a fundamental political concept: contestations or endorsements of freedom-conceptions concern the fundamental normative orientation of sociopolitical orders. Focusing on “freedom,” this article argues that the project of bringing about emancipatory sociopolitical orders is both aided by efforts at engineering fundamental political concepts as well as required by such ameliorative ambitions. I first argue that since the absence of ideology is a constituent feature of emancipa…Read more

890Saving Migrants’ Basic Human Rights from Sovereign RuleAmerican Political Science Review 1-14. 2022.States cannot legitimately enforce their borders against migrants if dominant conceptions of sovereignty inform enforcement because these conceptions undermine sufficient respect for migrants’ basic human rights. Instead, such conceptions lead states to assert total control over outsiders’ potential cross-border movements to support their in-group’s self-rule. Thus, although legitimacy requires states to prioritize universal respect for basic human rights, sovereign states today generally fail t…Read more

796Structural Injustice and Socially Undocumented Oppression: Changing Tides in Refugee and Immigration EthicsEthical Theory and Moral Practice 24 (4): 1047-1052. 2021.In this review essay, I discuss two recent works in refugee and migration ethics, Serena Parekh’s No Refuge: Ethics and the Global Refugee Crisis and Amy Reed-Sandoval’s Socially Undocumented: Identity and Immigration Justice. I find that their methodological ambitions overlap significantly and that their arguments represent welcome and largely successful examinations of generally neglected issues. I also explain how both approaches could fruitfully learn from each other, and argue that they lay…Read more

69Deportation, harms, and human rightsEthics and Global Politics 14 (2): 98-109. 2021.In Justice for People on the Move, Gillian Brock constructs an elaborate normative framework, based on human rights practice, to assess how states must treat international migrants in order to legitimate exclusionary claims to self-determination. In this discussion piece, I argue that this framework cannot always satisfactorily explain when and why it is impermissible for legitimate states to remove irregular migrants from their territory (i.e. deport them). I show that Brock’s intuitions about …Read more
