The rules were first adopted on 30 August 1955 during a UN
Congress on the Prevention of Crime and the Treatment of Offenders, held at
Geneva, and approved by the
Economic and Social Council in resolutions of 31 July 1957 and 13 May 1977. Since their adoption by the Economic and Social Council in 1957, the Standard Minimum Rules for the Treatment of Prisoners (SMR) have served as the universally acknowledged minimum standards for the treatment of prisoners. Despite their legally non-binding nature, the rules have been important worldwide as a
source for relevant national legislation as well as of practical guidance for prison management. Although not legally binding, the SMRs provide guidelines for
international and
domestic law for citizens held in
prisons and other forms of custody. The basic principle described in the standard is that "There shall be no
discrimination on grounds of race, color, sex, language, religion, political or other opinion, national or social origin, property, birth or other status". ==Scope==
