Law and You > Criminal Laws > Bharatiya Nyaya Sanhita, 2023 > Solitary Confinement under BNS (Ss. 11 and 12)
Solitary confinement is one of the most severe forms of punishment recognized under criminal law. It involves the physical isolation of a prisoner from other inmates for a specified period as part of a judicially imposed sentence. Under the Bharatiya Nyaya Sanhita, 2023 (BNS), solitary confinement is permitted as an additional punishment in cases of rigorous imprisonment, but it is subject to strict statutory limitations. Sections 11 and 12 of the BNS regulate the extent and duration of such confinement to prevent abuse and excessive hardship.
Although legally sanctioned, solitary confinement raises serious concerns relating to human dignity, mental health, and constitutional protections. The courts in India have repeatedly emphasized that its imposition must be carefully controlled and must comply with the guarantees of personal liberty under Article 21 of the Constitution. Thus, solitary confinement under the BNS represents a delicate balance between maintaining prison discipline and safeguarding the fundamental rights of prisoners.
Guidelines for the use of solitary confinement in Indian jails are provided by the BNS, the jails Act of 1894, and the Model Prison Manual of 2016. The Model Prison Manual forbids the use of solitary confinement as a form of punishment for inmates who suffer from mental diseases and mandates that inmates in solitary confinement have access to legal and medical assistance.

Meaning of Solitary Confinement under BNS:
Solitary confinement refers to a form of punishment in which a prisoner is kept in complete or near-complete isolation from other inmates for a specified period. The prisoner is confined alone in a separate cell and is denied normal interaction, communication, and association with others, except for limited contact with prison staff. Under the Bharatiya Nyaya Sanhita, 2023, solitary confinement is not an independent sentence but an additional punishment that may be imposed along with rigorous imprisonment. Thus, solitary confinement means keeping a prisoner isolated as a punitive measure, subject to strict legal limits and constitutional safeguards.
Legal Provisions of Solitary Confinement under BNS:
Section 11 BNS:
Solitary Confinement:
Whenever any person is convicted of an offence for which under this Sanhita the Court has power to sentence him to rigorous imprisonment, the Court may, by its sentence, order that the offender shall be kept in solitary confinement for any portion or portions of the imprisonment to which he is sentenced, not exceeding three months in the whole, according to the following scale, namely: —
(a) a time not exceeding one month if the term of imprisonment shall not exceed six months;
(b) a time not exceeding two months if the term of imprisonment shall exceed six months and shall not exceed one year;
(c) a time not exceeding three months if the term of imprisonment shall exceed one year.
Section 12 BNS:
Limit of Solitary Confinement:
In executing a sentence of solitary confinement, such confinement shall in no case exceed fourteen days at a time, with intervals between the periods of solitary confinement of not less duration than such periods; and when the imprisonment awarded shall exceed three months, the solitary confinement shall not exceed seven days in any one month of the whole imprisonment awarded, with intervals between the periods of solitary confinement of not less duration than such periods.
Limit of Solitary Confinement under BNS:
- If imprisonment ≤ 6 months → solitary confinement not more than 1 month.
- If imprisonment > 6 months but ≤ 1 year → not more than 2 months.
- If imprisonment > 1 year → not more than 3 months.
- It cannot exceed 14 days at a time.
- There must be an interval between periods.
Provisions under Prisoner’s Act 1894:
Section 29
Solitary Confinement:
No cell shall be used for solitary confinement unless it is furnished with the means of enabling the prisoner to communicate at any time with an officer of the prison, and immediately on his arrival in the prison after sentence, be every prisoner so confined in a cell for more than twenty-four hours, whether as a punishment or otherwise, shall be visited at least once a day by the Medical Officer or Medical Subordinate.
Section 30:
Prisoners under Sentence of Death:
(1) Every prisoner under sentence of death shall, immediately on his arrival in the prison after sentence, be searched by, or by order of, the Jailor and all articles shall be taken from him which the Jailor deems it dangerous or inexpedient to leave in his possession.
(2) Every such prisoner shall be confined in a cell apart from all other prisoners, and shall be placed by day and by night under the charge of a guard.
Purpose of Solitary Confinement:
Use of solitary confinement is limited and regulated, and it serves specific penal objectives within the criminal justice system. It is the most rigorous form of punishment which is generally given to those who are threatful not only to society but also to the other prisoners of jail. The key purposes of solitary confinement are:
- Deterrence: One of the primary purposes is to deter offenders from committing serious offences. The severity of isolation is intended to discourage both the offender and others from engaging in criminal conduct.
- Discipline: Solitary confinement helps maintain discipline within prisons. It may be imposed in cases involving grave offences where stricter punishment is considered necessary.
- Punitive Objective: It serves as an additional punishment along with rigorous imprisonment. The isolation intensifies the severity of the sentence in appropriate cases.
- Protection and Security: In certain situations, isolation may help prevent violence, protect other inmates, or maintain institutional security (though this is more administrative than punitive).
- Reflection and Reform (Theoretical Objective): Traditionally, it was believed that isolation would allow the offender time for reflection and repentance. However, modern penology questions this assumption due to psychological impacts.
While solitary confinement aims to achieve deterrence, discipline, and punishment, courts emphasize that it must be imposed cautiously and within statutory limits to safeguard human dignity and constitutional rights.
Constitutional Safeguards:
Although solitary confinement is legally recognized under the Bharatiya Nyaya Sanhita, its imposition is strictly controlled by constitutional protections. The Indian Constitution ensures that even prisoners retain fundamental rights.
Article 21 guarantees that no person shall be deprived of life or personal liberty except according to procedure established by law. The Supreme Court has interpreted this to include the right to live with human dignity. Solitary confinement must not be cruel, inhuman, or degrading. Any arbitrary or excessive isolation violates Article 21.
Solitary confinement can only be imposed by a court of law, not arbitrarily by prison authorities. Proper legal procedure must be followed. The punishment must fall within statutory limits.
International Standards and Guidelines:
The use of solitary confinement is governed by the Mandela Rules, commonly known as the United Nations Standard Minimum Rules for the Treatment of Prisoners. According to the Mandela Rules, solitary confinement should only be utilised in extreme circumstances and for a brief period of time. Additionally, they demand that prisoners in solitary confinement have access to basic amenities like legal representation and medical care. The use of torture and other cruel, inhumane, or humiliating treatment, including lengthy solitary confinement, is prohibited by the United Nations Convention against Torture and other Cruel, Inhuman, or humiliating Treatment or Punishment.
Important Judicial Decisions:
In Sunil Batra v. Delhi Administration (1978) case, the Supreme Court of India ruled that prolonged solitary confinement could amount to cruel and unusual punishment, violating the fundamental rights guaranteed under the Indian Constitution. The court also held that the use of solitary confinement should be limited and subject to regular review.
In Charles Sobhraj v. Superintendent, Central Jail, AIR 1978 SC 1514 case, the court found that the use of prolonged solitary confinement for an extended period of time violated the prisoner’s right to life and liberty under the Indian Constitution.
In Nilabati Behera v. State of Orissa, AIR 1993 SC 1960 case, the Supreme Court held that the use of torture, including solitary confinement, was a violation of the right to life under Article 21 of the Indian Constitution. The court also held that victims of torture were entitled to compensation.
In Kishore Singh v. State of Rajasthan, AIR 1981 SC 62 case it was held that a sentence inflicting solitary confinement for the whole term of imprisonment is illegal if exceeding 14 days. It must bear only a portion of the term of imprisonment.
In PUCL v. State of Maharashtra, AIR 2014 SCW 5940 case, the court ruled that the use of solitary confinement was a violation of the right to life and dignity under the Indian Constitution. The court directed the government to establish guidelines for the use of solitary confinement and to ensure that the use of solitary confinement was subject to regular review.
In Shatrughan Chauhan v. Union of India, 2014 AIR SCW 793 case, the Supreme Court said that prolonged delay in execution of a sentence of death had a dehumanizing effect and this had the constitutional implication of depriving a person of his life in an unjust, unfair and unreasonable way so as to offend the fundamental right under Article 21 of the Constitution.
Criticism of Solitary Confinement:
Solitary confinement has been widely criticized for its severe psychological impact on prisoners. Extended periods of isolation can cause anxiety, depression, hallucinations, paranoia, and even suicidal tendencies. Since human beings are inherently social, prolonged deprivation of interaction can seriously damage mental stability and emotional well-being.
Another major criticism relates to the violation of human dignity. Even though solitary confinement is permitted under the Bharatiya Nyaya Sanhita, it must comply with constitutional safeguards. Article 21 of the Constitution guarantees the right to life and personal liberty, which includes the right to live with dignity. Harsh or prolonged solitary confinement may amount to cruel, inhuman, or degrading treatment.
Critics further argue that solitary confinement is inconsistent with the reformative theory of punishment. Modern criminal jurisprudence focuses on rehabilitation rather than retribution. Isolation may increase aggression, resentment, and antisocial behaviour instead of encouraging reform and reintegration into society.
Thus, while solitary confinement is legally regulated, it continues to face serious criticism due to its psychological effects, constitutional concerns, and conflict with modern principles of reformative justice.
Alternatives to Solitary Confinement
Although solitary confinement is permitted under the Bharatiya Nyaya Sanhita, modern penology increasingly favours less harmful and more reformative measures. Courts and human rights bodies emphasize that punishment should preserve human dignity and promote rehabilitation.
- Separate Confinement (With Limited Interaction): Prisoner is kept in a separate cell. Allowed controlled communication is allowed and activities are supervised. It is less psychologically harmful than strict isolation.
- Loss of Privileges: Certain facilities like canteen, recreation, and visits are suspended temporarily. It acts as a disciplinary measure without total isolation. It is proportionate response to misconduct.
- Close Supervision Units: There is increased monitoring instead of isolation. It ensures security while allowing social interaction. It is suitable for high-risk inmates.
- Counseliing and Psychological Intervention: Behavioural therapy for violent or disruptive prisoners is given which includes anger management and conflict-resolution programs. It addresses root causes rather than imposing harsh punishment.
- Mediation and Restorative Justice Practices: It encourages dialogue and accountability. It focuses on repairing harm rather than inflicting suffering. It promotes reformative justice principles.
- Transfer to High-Security Facilities: It is suitable for inmates posing serious threats. It maintains safety without complete social deprivation.
- Structured Work and Educational Programs: it includes Vocational training, Literacy and skill development. This productive engagement reduces indiscipline.
Conclusion:
Solitary confinement under the Bharatiya Nyaya Sanhita serves as a legally recognized form of additional punishment for rigorous imprisonment. However, its use is strictly regulated through statutory limits to prevent abuse and safeguard prisoners’ rights. The constitutional framework, particularly Article 21, ensures that solitary confinement must not violate human dignity or constitute cruel and degrading treatment.
While the punishment aims to maintain prison discipline, deter serious offenses, and reinforce accountability, its psychological and rehabilitative drawbacks have drawn widespread criticism. Courts have emphasized that solitary confinement should be imposed cautiously, with judicial oversight, and within the prescribed limits. Modern penology encourages reformative and humane alternatives, such as separate confinement with controlled interaction, counselling, and structured rehabilitation programs, to achieve prison discipline without compromising mental health.
Ultimately, solitary confinement represents a delicate balance between maintaining order within prisons and upholding the fundamental rights of inmates. Its proper application reflects the broader goals of justice: deterrence, discipline, and reform, while ensuring that punishment remains humane and constitutionally compliant.
