Checking Rights at the Border : Migrant Detention in International and Comparative Law

Human rights laws, both international and domestic, present a challenge to the sovereign rights of states. The right to determine who may enter a state is one of the fundamental attributes of sovereignty. Under international law, however, states cannot return a migrant with a potentially valid asylum claim to a place where his life will be in danger, and cannot return any migrant to a place where he might be tortured. States often detain migrants while processing their asylum claims, and pending deportation if those claims should fail. Yet international law, and many states' domestic laws, prohibit prolonged detention and restrict detention conditions. As migration flows and detention rates have swelled globally, high courts have increasingly decided cases involving the rights of detained migrants. On February 27, 2018, the U.S. Supreme Court handed down a critical decision on this issue in Jennings v. Rodriguez, allowing thousands of immigrants and asylum seekers to be detained indefinitely, without bail hearings, while remanding the case for consideration of their constitutional claims. This article compares court cases involving detention of migrants in the United States, Australia, and Europe to determine how states can comply with human rights law while preserving their right to protect their borders. Based on these cases, the article proposes best practices for state compliance with international law on detention. This comparison illuminates how courts strike a delicate balance between human rights and state sovereignty where national security interests are at stake
