The book addresses the current issue of the applicability and application of international human rights law and international humanitarian law in times of armed conflict. Scholars chronologically argued that only international humanitarian law was applicable, that both legal regimes were applicable, and eventually that international humanitarian law was the lex specialis of human rights law. The most recent trend, supported by the research carried out in this book, shows that international humanitarian law and human rights law are slowly merging into a single set of rules. The book examines general issues relating to applicability and the implementation of the two legal regimes as well as provides case studies focusing on specific rights or persons.
