Deportation in International Law and Comparative Perspective

Join us for an expert panel discussion to explore comparative perspectives on immigration law and the practice of deportation at an international level.
Event Overview
This is a hybrid event. Please register here to attend virtually on Zoom. Lunch will be provided for in-person attendees.
The last three months have been marked by consequential events involving immigration and deportation law. Some of these included the executive order on birthright citizenship, forceful deportation practices, and the use of deportation as a tool for promoting non-immigration policies. These events raise important legal questions such as whether countries have unlimited ability to deport non-citizens as a function of the precept of state sovereignty. While states exercise a great deal of latitude in shaping immigration law and policy, their powers are also not unconstrained. State prerogatives are generally limited by rule of law, constitutional rights, as well as customary international law and treaty norms connected with expulsion of non-citizens and human rights.
Join us for an event that brings together a panel of authors of a prospective book on comparative migration law on deportation to explore the experience of deportation law and practice at an international level. Moderated by Professor Gerald Neuman, members of the panel, composed of scholars and practitioners from Australia, China, and France and an upcoming judge of European Court of Human Rights, will share their thoughts and findings in the area.
