PIL.OT / DEVELOPMENT
PIL.OTv0.62.2
Emil Śliwiński examines how terrorism-based deprivation of citizenship should be assessed for proportionality under the European Convention on Human Rights. The article compares ECtHR cases involving citizenship deprivation on terrorism grounds with citizenship case law arising in other contexts.
The Court’s approach centres on two questions: whether the deprivation is arbitrary and what consequences denationalisation has for the individual. Śliwiński argues that the content of both elements remains insufficiently clear and draws on Article 8 ECHR, Article 3 of Protocol No. 1 and Article 3 of Protocol No. 4 to develop a more coherent set of proportionality criteria.
Whether deprivation of citizenship on terrorism-related grounds is proportionate under the European Convention on Human Rights.
The article frames the proportionality problem raised by terrorism-based deprivation of citizenship under the ECHR. The available material does not establish that it changes or confirms a particular judicial approach, or that it develops a link with another decision or instrument.
