The United Nations Standard Minimum Rules for Non-custodial Measures (The Tokyo Rules) was adopted by the United Nations General Assembly on December 14, 1990. The Tokyo Rules sets forth the principles to be followed by member nations in order to promote the use of non-custodial measures, and minimum safeguards for persons subject to alternatives to imprisonment. Creation of Tokyo Rules took its inspiration from the Universal Declaration of Human Rights, the International Covenant on Civil and Political Rights, and many other international human rights instruments relating to rights of persons in conflict with the law.
In addition to adopting the rules, member nations are also required to report the implementation of Tokyo Rules every five years. The United Nations Secretary-General is required to prepare a report every five years on the implementation of the Tokyo Rules for submission to the Committee on Crime Prevention and Control.
