International human rights law (IHRL) governs the obligations of States towards citizens and other individuals within their jurisdiction. Human rights law enshrines the highest of human ideals, that every human being has a set of rights and freedoms. Human rights thus cannot be taken away by States and apply at all times (although specific derogations and limitations are permitted to certain rights and freedoms). Set forth in the Universal Declaration of Human Rights and a host of core treaties, IHRL plays a crucial role in the protection of all people. Human rights law also defines the rights of specific vulnerable groups like IDPs or children.
