The UN Nelson Mandela Rules are the United Nations Standard Minimum Rules for the Treatment of Prisoners, a set of 122 standards covering how prisons should be run, from cell conditions and healthcare to solitary confinement and inspections. The General Assembly unanimously re-adopted them in December 2015 under Resolution 70/175, renaming the 1955 original to honor Nelson Mandela, who spent 27 years imprisoned during his struggle for human rights in South Africa.1United Nations.

Are the Rules Legally Binding
No. The Mandela Rules are “soft law.” National law takes precedence, and a prisoner cannot walk into court and enforce Rule 44 the way they could invoke a constitutional right.2United Nations Office on Drugs and Crime. Nelson Mandela Rules History
They still carry weight. The General Assembly adopted them unanimously, so they represent what the international community has agreed is the minimum acceptable standard. Many countries have folded the rules into their own prison legislation, and courts in various jurisdictions use them as a reference point when deciding whether conditions violate domestic constitutional protections. Any facility operating below them is, by global consensus, operating beneath what is acceptable.
Core Principles
Rule 1 is the foundation: every prisoner must be treated with respect for their inherent dignity, and no circumstance justifies torture or cruel, inhuman, or degrading treatment. Rule 2 prohibits discrimination based on race, sex, language, religion, political opinion, national origin, or any other status, and requires reasonable accommodations so prisoners with disabilities can participate in prison life on an equal basis.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)
Rule 5 sets out a principle that shapes the whole framework: prison life should resemble life outside prison as closely as possible. Imprisonment restricts liberty; it is not meant to strip away every other aspect of a normal life.
Living Conditions
Rules 12 through 23 set the physical floor. Every prisoner needs a sleeping area with adequate floor space, enough air volume, natural and artificial light sufficient for reading without eye strain, and ventilation that supplies fresh air at temperatures appropriate to the climate. Clothing provided by the facility cannot be degrading. Facilities must supply water and hygiene materials needed for health and cleanliness. Food must be nutritious, well-prepared, and served at regular hours, and clean drinking water must be available at all times.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)
Rule 23 requires at least one hour of exercise in the open air each day for any prisoner who does not already work outdoors, weather permitting. Prisoners must also be kept informed of important news through newspapers, periodicals, radio, lectures, or similar means, and they must be allowed to practice their religion, keep religious books, and meet with a qualified religious representative where numbers warrant one.
Separation of Categories
Rule 11 requires that different groups be held apart. Men and women go in separate institutions or entirely separate wings. People awaiting trial must be kept apart from those already convicted. People imprisoned for civil matters such as debt must be separated from those held on criminal charges. Young prisoners must be kept apart from adults.
Healthcare
Rule 24 makes healthcare for prisoners a direct state responsibility. The standard is simple: the same quality of care available in the community, free of charge, without discrimination based on legal status. Every prison must maintain a healthcare team with expertise in psychology, psychiatry, and dentistry.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)
Rule 25 requires that these professionals operate with full clinical independence, meaning their medical decisions cannot be overridden by prison management or security staff. In practice this is one of the rules most often compromised, with security concerns overriding clinical judgment in facilities around the world.
Every new arrival must be screened for mental health conditions, contagious diseases, and signs of prior ill-treatment. Under Rule 34, when healthcare staff find evidence of torture or abuse during any examination, they must document it and report it to the appropriate medical, administrative, or judicial authority, taking care not to put the prisoner at further risk. Healthcare workers must also pay particular attention to the mental health of prisoners held in segregation, and when a facility cannot provide needed treatment, the prisoner must be transferred to a civilian hospital or specialized institution.
Solitary Confinement and Banned Punishments
Before any disciplinary sanction is imposed, the prisoner must be told the charges in a language they understand and given a real opportunity to defend themselves, including the right to seek legal assistance. No one may be punished twice for the same offense, and collective punishment is always prohibited.
Rule 43 bans certain punishments outright:
- Indefinite or prolonged solitary confinement. Solitary means 22 or more hours a day without meaningful human contact, and “prolonged” means anything beyond 15 consecutive days.
- Placement in dark cells or in cells where the light is never turned off.
- Reduction of a prisoner’s food or drinking water as punishment.
- Corporal punishment in any form.
- Collective punishment.
Restraints may never be used as a disciplinary sanction, and discipline may never include banning family contact. Any restriction on how a prisoner communicates with family can only be temporary and strictly necessary for security.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)
The 15-day cap on solitary confinement is among the most cited provisions in the framework. It reflects decades of research showing that extended isolation causes serious psychological damage, including anxiety, hallucinations, and cognitive deterioration. Many prison systems still exceed this limit routinely, which is why the 2015 revision made the prohibition explicit.
Restraints and Use of Force
Chains, irons, and any inherently degrading restraint device are prohibited under all circumstances. Other restraints may be used only when necessary to prevent escape during transfer, on the direction of a medical professional, or to stop a prisoner from injuring themselves or others, and they must be removed the moment the immediate risk passes. Restraints are never permitted on women during labor or immediately after childbirth.
Staff may use force against prisoners only in self-defense, to prevent an escape, or to overcome active or passive resistance to a lawful order. When force is used, it must be the minimum necessary, and the incident must be reported to the prison director. Staff who work in direct contact with prisoners should generally not carry weapons, and no staff member may be issued a firearm without specific training in its use.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)
Searches must respect dignity, privacy, proportionality, and necessity. Strip and body cavity searches must happen only when absolutely necessary, in private, by staff of the same sex as the prisoner, and body cavity searches must be done by a qualified healthcare professional who is not the prisoner’s primary care provider, or at minimum by staff trained in medical hygiene standards. Every strip search, cavity search, and cell search must be logged.
Contact With Family, Lawyers, and Consulates
Rule 58 requires that prisoners be able to communicate with family and friends at regular intervals through letters, phone calls, electronic means, and in-person visits. Rule 59 directs that prisoners be placed in facilities close to their home or place of social rehabilitation whenever possible. Visitors may be searched if they consent, but searches must be proportionate and not degrading, and body cavity searches of visitors must be avoided entirely. Children visiting a facility must never be subjected to body cavity searches.
Legal communication gets the strongest protection. Under Rule 61, prisoners must have adequate time and facilities to consult with their legal adviser without delay, interception, or censorship, and in full confidentiality. Staff may observe these meetings visually but must remain out of hearing range.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)
Foreign nationals must have reasonable access to the diplomatic or consular representatives of their home country. Refugees and stateless persons with no embassy to contact are entitled to similar access through whichever state handles their interests or through a national or international body that protects such individuals.
On admission, transfer, or serious illness or injury, a prisoner must be allowed to notify their family or emergency contact immediately. If a prisoner dies, the director must inform the next of kin at once. A prisoner must also be told promptly if a close family member becomes critically ill or dies, and should be allowed to attend a deathbed or funeral, under escort or alone, when circumstances permit.
Complaints Without Retaliation
Rule 56 gives every prisoner the right to make requests or complaints daily to the prison director or an authorized staff member. Prisoners can also raise issues directly with an inspector during inspections, freely and confidentially, with no prison staff present. Complaints can be submitted to the central prison administration or to judicial authorities with review power, and the content cannot be censored.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)
Rule 57 addresses retaliation directly. Complaints must be dealt with promptly, and if rejected or ignored, the prisoner can escalate to a judicial authority. Safeguards must allow complaints to be made safely and confidentially, and no one who files a complaint can face retaliation or intimidation. Allegations of torture or degrading treatment trigger an immediate, independent investigation. If a prisoner cannot exercise these rights personally, their lawyer, a family member, or anyone with knowledge of the case can file on their behalf.
Rehabilitation: Work and Education
The rules treat rehabilitation as the central purpose of imprisonment for sentenced prisoners, not an optional add-on. Rule 4 requires prison administrations to offer education, vocational training, work, and other support including health, social, and sports-based programs, tailored to each prisoner’s needs.
Sentenced prisoners must have the opportunity to work, provided a medical professional confirms they are physically and mentally fit. The work cannot be punitive. Prisoners cannot be held in forced labor, and no prisoner may be required to work for the personal benefit of any staff member. Workplace safety protections must match those applied to workers outside prison, and prisoners injured on the job are entitled to compensation on terms no less favorable than what free workers receive under law. Hours must be set by law and leave at least one rest day per week plus enough time for education and rehabilitation activities. There must be a system of fair compensation, and prisoners must be allowed to spend part of their earnings, send a portion to their family, and have a portion saved for release.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules)
Education must be available to all prisoners capable of benefiting from it. For illiterate prisoners and young prisoners, it is compulsory, not optional. Programs should integrate with the national education system so a person released from prison can continue their studies without starting over. Vocational training in practical trades must also be offered, with particular emphasis on young prisoners.
Inspections and Oversight
Rule 83 establishes a dual inspection system: internal reviews by the prison administration itself, and external inspections by an independent body. The internal review catches operational failures. The external inspection, which may include international or regional human rights bodies, provides the accountability check no system can give itself.
External inspection teams must include healthcare professionals and reflect balanced gender representation. Under Rule 84, inspectors can access all information about prisoner numbers and conditions, freely choose which prisons to visit including unannounced, select which prisoners to interview, and conduct those interviews privately and in full confidentiality.3United Nations Office on Drugs and Crime. The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules) The unannounced-visit power matters: facilities that know when inspectors are coming can prepare, so the ability to arrive without warning is what gives inspections real teeth.
Every inspection must produce a written report. External inspection reports should generally be made public, with personal prisoner data excluded unless the prisoner consents. The prison administration must then indicate, within a reasonable time, whether it will implement the recommendations.
