Introduction of BNS Section 11
BNS Section 11 of the Bharatiya Nyaya Sanhita (BNS), 2023, deals with the use of solitary confinement as part of a prison sentence. It empowers the court to order that an offender spend a certain portion of their imprisonment in complete isolation, away from other prisoners. However, the law sets clear time limits to ensure solitary confinement is used carefully and only in exceptional cases.
The Bharatiya Nyaya Sanhita (BNS) Section 11 replaces the old Indian Penal Code (IPC) Section 73.
What is section 11 of BNS ?
BNS Section 11 allows a court to add solitary confinement to a person’s prison sentence if they commit a serious crime. The time they spend in solitary confinement depends on how long their total prison sentence is, but it cannot be more than three months.

BNS Section 11 in Simple Points
Whenever a person is sentenced to rigorous imprisonment, the court may order that a part of the imprisonment be solitary confinement, subject to the following limits:
– Not more than 1 month if imprisonment is up to 6 months.
– Not more than 2 months if imprisonment exceeds 6 months but does not exceed 1 year.
– Not more than 3 months in any other case.
1. Meaning of Solitary Confinement
Solitary confinement means keeping a prisoner alone in a separate cell, away from other inmates, as part of the punishment. It is not a separate sentence but an additional measure imposed by the court within a prison term.
Purpose:
- To discipline prisoners guilty of serious crimes.
- To add severity to a sentence when the offence requires stricter punishment.
- To deter others from committing similar crimes.
2. Essential Ingredients of the Offence (When Solitary Confinement Applies)
For solitary confinement to be imposed under Section 11, the following must exist:
- Rigorous Imprisonment:
The offender must be sentenced to rigorous imprisonment (involving hard labour), not simple imprisonment. - Judicial Order:
The court must specifically order solitary confinement. - Time Limits Based on Sentence:
- Imprisonment ≤ 6 months → Solitary confinement ≤ 1 month.
- Imprisonment > 6 months and ≤ 1 year → Solitary confinement ≤ 2 months.
- Imprisonment > 1 year → Solitary confinement ≤ 3 months.
Without these conditions, solitary confinement cannot be legally imposed.
3. Punishment under BNS Section 11
- Type: Solitary confinement in addition to rigorous imprisonment.
- Duration: Strictly limited; never beyond 3 months total.
- Judicial Control: Only a court can decide when and how it applies.
4. Nature of the Offence
- Bailable / Non-Bailable: Depends on the main offence, not Section 11 itself.
- Cognizable / Non-Cognizable: Based on underlying offence.
- Compoundable / Non-Compoundable: Based on main offence.
- Trial By: Ordinary criminal courts.
Section 11 is procedural in nature — it regulates punishment but does not define a new crime.
5. Examples of BNS Section 11 in Action
- Example 1 – Long Sentence:
A person is sentenced to 5 years rigorous imprisonment for dacoity. The court may order up to 3 months solitary confinement. - Example 2 – Medium Sentence:
An offender is sentenced to 10 months rigorous imprisonment. The court may order up to 2 months solitary confinement. - Example 3 – Short Sentence:
A convict gets 4 months rigorous imprisonment. The court may order up to 1 month solitary confinement. - Not Applicable:
If a person is sentenced to simple imprisonment, solitary confinement cannot be ordered.
6. Importance of BNS Section 11
- Ensures discipline in prisons by allowing stricter punishment for hardened criminals.
- Balances deterrence with human rights by setting maximum limits (no more than 3 months).
- Continues the framework of IPC Section 73, but under BNS it is more carefully worded to avoid misuse.
- Reflects the judiciary’s role in ensuring fair and proportionate punishment.
Section 11 BNS Overview
BNS Section 11 lets a court add solitary confinement to a person’s prison sentence for serious crimes. The length of solitary confinement depends on the total prison sentence but cannot exceed three months.
BNS Section 11: 10 key points
1. Solitary Confinement as a Punishment
BNS Section 11 permits the court to impose solitary confinement as part of a punishment when a person is sentenced to rigorous imprisonment. This is not a separate punishment but an additional measure that can be attached to the main sentence, especially for serious crimes.
2. Court’s Authority
The power to order solitary confinement rests solely with the court. The judge assesses the gravity of the crime, the conduct of the offender, and the circumstances before deciding whether solitary confinement should be imposed.
3. Duration Based on Sentence Length
The law sets specific guidelines on how long solitary confinement can last, depending on the total term of imprisonment. This prevents excessive use of solitary confinement and ensures proportionality between the crime and the punishment.
4. Shorter Sentences
If a person is sentenced to imprisonment for six months or less, the court can order solitary confinement for up to one month only. This ensures that the punishment is not overly harsh for relatively shorter prison terms.
5. Medium-Length Sentences
When imprisonment is more than six months but does not exceed one year, solitary confinement may be imposed for a maximum of two months. This balances the seriousness of a slightly longer prison term with controlled use of solitary confinement.
6. Longer Sentences
For imprisonment extending beyond one year, the court can impose solitary confinement for up to three months. This is the maximum limit provided under BNS Section 11, ensuring that even in serious cases, solitary confinement cannot be indefinite.
7. Total Confinement Limit
Regardless of how long the imprisonment is, solitary confinement can never exceed three months in total. This safeguard protects prisoners from prolonged isolation, which could have severe mental and physical effects.
8. Portion of Imprisonment
The court may apply solitary confinement to any portion of the overall imprisonment term. For example, it can be ordered at the beginning, middle, or end of the sentence, depending on what the court considers appropriate.
9. Purpose of Solitary Confinement
The main goal of allowing solitary confinement is to add a stricter element of punishment for offenders who have committed serious crimes. However, it is meant to be used sparingly and within limits, not as a routine form of imprisonment.
10. Judicial Discretion
Ultimately, whether solitary confinement is applied or not depends on the discretion of the judge. The court must carefully consider the nature of the crime, the behavior of the accused, and the principles of justice before imposing solitary confinement.
Comparison: BNS Section 11 vs IPC Section 73
| Section | Provision | Maximum Solitary Confinement | Judicial Discretion |
|---|---|---|---|
| BNS Section 11 | Allows solitary confinement as part of rigorous imprisonment, subject to strict limits. | Up to 3 months, depending on total sentence length. | Court decides if and when solitary confinement applies. |
| IPC Section 73 (1860) | Also allowed solitary confinement but under colonial-era framework. | Same 3-month maximum, but with less emphasis on human rights safeguards. | Court discretion applied, though older wording left scope for stricter application. |
