This book explores a specific discursivity at work in international human rights law. It examines the ways in which the discourse on international human rights law constantly expands its domain while preserving its distinctiveness from general international law. It particularly exposes the oscillations between generalist and exceptionalist claims made in international human rights law for the sake of expanding its scope. Reviewing several contemporary controversies on international human rights law, it sheds lights on the possible drivers behind such expansionist discursivity.
