The United Nations Standard Minimum Rules for the Treatment of Prisoners were adopted by the United Nations General Assembly on 17 December 2015 after a five-year revision process. They are known as the Mandela Rules in honor of the former South African President, Nelson Mandela. The Mandela Rules are composed of 122 "rules". Not all are rules, but some are principles such as institutional equality and the philosophy of confinement.
