Introduction of Section 166 BNS
166 BNS criminalizes the abetment of acts of insubordination by members of India’s armed forces (Army, Navy, Air Force). If a civilian or service member encourages, assists or instigates a soldier, sailor or airman to disobey lawful orders and that disobedience occurs as a result, the abettor can face imprisonment for up to two years, a fine, or both. The provision is aimed at safeguarding the chain of command and military discipline by deterring outside influence or internal provocations that could undermine operational effectiveness.
The Bharatiya Nyaya Sanhita (BNS) Section 166 replaces the old Indian Penal Code (IPC) Section 138.

Key Points of BNS Section 166
- Abetment of Insubordination:
- This section deals with cases where an individual actively supports or encourages military personnel (soldiers, sailors, or airmen) to disobey lawful commands from their superiors.
- The encouragement must lead to the actual act of insubordination for the abettor to be held liable.
- Applicable to Military Personnel:
- This law is specifically meant for military personnel serving in the Army, Navy, or Air Force. It ensures that the discipline within these forces is maintained and that external influences do not encourage disobedience.
- Act of Insubordination Must Occur:
- The punishment under this section applies only if the act of insubordination actually happens due to the encouragement or abetment by the person involved.
- Punishment:
- If found guilty of abetting the insubordination, the accused may face imprisonment for up to two years, a fine, or both. This is intended to act as a deterrent against encouraging military disobedience.
- Imprisonment and Fine:
- The punishment is designed to be flexible, offering a combination of imprisonment and/or fine, depending on the severity and circumstances of the case.
- Cognizable Offense:
- Since it is a cognizable offense, the police have the authority to arrest the accused without the need for a warrant. This allows for immediate legal action to be taken to maintain military discipline.
- Bailable Offense:
- The offense is bailable, which means the accused can apply for bail and does not necessarily need to remain in custody while awaiting trial.
- Non-Compoundable:
- This offense is non-compoundable, which means the case cannot be privately settled between the parties. It must be decided by a court.
- Tried by Any Magistrate:
- The trial of cases under Section 166 can be handled by any magistrate in a court of law, ensuring the case can proceed at any level of the judiciary.
- Importance of Military Discipline:
- The purpose of Section 166 is to maintain the integrity and discipline of the Indian Armed Forces. By punishing those who attempt to influence military personnel to act against their duties, the law ensures the chain of command remains strong and effective.
BNS Section 166 : Examples
Example 1:
A civilian friend of an Army soldier encourages him to disobey a direct order from his commanding officer. The soldier, influenced by the friend’s encouragement, refuses to follow the command. The civilian friend can be punished under Section 166 for abetting the insubordination, and could face imprisonment or a fine.
Example 2:
A sailor in the Indian Navy is convinced by a colleague to ignore a command during a mission. Because the colleague influenced the sailor’s decision to act against orders, the colleague can be held responsible under Section 166, and may be sentenced to jail or fined.

Comparison – BNS Section 166 vs IPC 138
| Section | What it Means | Punishment | Bail | Cognizable? | Trial By |
|---|---|---|---|---|---|
| BNS Section 166 | Addresses abetment of acts of insubordination by soldiers, sailors, or airmen of India’s armed forces. If disobedience occurs because of such abetment, the abettor is punishable. | Imprisonment up to 2 years, or fine, or both. | Bailable (accused can apply for bail). | Cognizable (police can arrest without warrant). | Any Magistrate. |
| IPC Section 138 (Old Law) | Penalized abetment of insubordination by any officer, soldier, sailor, or airman under the Indian Penal Code. Focused on maintaining discipline within the armed forces. | Imprisonment up to 2 years, or fine, or both (similar to BNS 166). | Bailable (same as under BNS 166). | Cognizable offence (warrant not required for arrest). | Any Magistrate. |
| Key Difference: BNS Section 166 refines and modernizes IPC Section 138 by clearly defining that punishment applies only when the act of insubordination actually occurs as a result of abetment. It simplifies language and maintains the same penalty to preserve discipline within the armed forces. | |||||
