The Common Core of the Fundamental Standards of International Humanitarian Law and International Human Rights Law

The presented paper discusses the convergence of international humanitarian law and international human rights law in armed conflicts. International human rights law and the human rights law converge and interact with each other because natural law is at the core of both these disciplines of public international law. Although international humanitarian law is a lex specialis, the general rules regarding the interpretation of treaties clearly indicate that international human rights law must be interpreted in the context of other rules of international law, and its possible derogations must be compatible with other international obligations of the state, including humanitarian law. In the event of a conflict between international humanitarian law and international human rights law, the mechanism for resolving conflicts between the standards was supplemented by an interpretation based on the principle of ‘system integration’ of the International Court of Justice which results in the ‘humanization’ of international humanitarian law. The evolution of the case-law of the European Court of Human Rights, which takes into account the international humanitarian law as the reference norm that should be referred to, demonstrates the close relationship between these areas of law. In the case of the application of universal and regional instruments of international human rights law, we are dealing with the ‘humanitarianization’ of these rights.
