This book investigates the legal and systemic paradox of non-removable migrants within the European Union, questioning why deportation policies consistently fail to achieve their stated objectives. Diego Ginés Martín, a legal scholar specializing in migration, examines the intersection of administrative law, human rights, and state sovereignty. He argues that the current European migration framework creates a state of permanent legal limbo for individuals who cannot be deported yet are denied formal residence, thereby exposing the structural contradictions inherent in modern migration control.

Legal scholars and policy analysts recognize this work as a critical contribution to the study of European migration law. Experts frequently highlight the text for its rigorous analysis of the administrative failures that perpetuate the precarious status of non-removable individuals.
