Today, the International Committee of the Red Cross (ICRC) has made available on its online, free of charge Customary IHL database an update of State practice of 7 countries and 3 tribunals relating to armed conflicts and humanitarian issues such as the distinction between combatants and civilians, the use of nuclear, biological and chemical weapons, the protection of internally displaced persons, the protection of children and in particular child soldiers, the prohibition of sexual violence and slavery, the integration of international humanitarian law (IHL) into the training and operations of armed forces, and the prosecution of war crimes.
Practice up till the end of 2010 of the following countries has been included for this most recent update of the Database: Armenia, Brazil, Cuba, El Salvador, Georgia, Nepal and New Zealand. Case-law of the Extraordinary Chambers in the Courts of Cambodia, the International Criminal Court and the International Court of Justice dealing with questions of IHL has also been updated. New practice is marked in green throughout the database.
The purpose of the Customary IHL database is to make not only the rules of customary IHL but also the underlying State and international practice easily accessible by everyone interested in the interpretation and application of IHL. The information in the database is easily accessible by means of three search parameters: subject matter, type of practice and country, which can be used separately or can be combined in a powerful search engine.
The database will continue to be updated with practice from about 100 countries and a number of relevant international bodies. The next updates of both national and international practice are scheduled for June and July 2014.
