The UN system for protection and enforcement of human rights consists of treaties, monitoring bodies, and special rapporteurs. Treaty-based mechanisms, such as the Human Rights Council, oversee the compliance of member states with the international human rights treaties they have ratified. Non-treaty-based mechanisms, like Special Rapporteurs, monitor and report on human rights violations. The UN supports these mechanisms through agencies, such as the Office of the High Commissioner for Human Rights (OHCHR), which ensure the effective promotion, protection, and fulfilment of human rights obligations globally.
