Criminal Procedure
Dispersal of Unlawful Assemblies under BNSS
Understand BNSS Sections 148 to 151 on commands to disperse, civil force, armed forces, minimum force, constitutional assembly rights and accountability.
The short answer
BNSS permits specified Magistrates and police officers to command an unlawful or peace-threatening assembly to disperse, and to use necessary force if it refuses. Armed forces are a later and exceptional step. Every response must remain lawful, necessary and proportionate, with as little force and injury as the situation permits.
When may an assembly be ordered to disperse?
Section 148 covers an unlawful assembly and an assembly of five or more persons that is likely to disturb public peace, but force follows only through the statutory sequence.
The constitutional starting point is that citizens may assemble peacefully and without arms. A gathering does not lose protection merely because its message is unpopular or inconvenient. The authority must identify the legal basis for treating the gathering as unlawful or likely to disturb public peace.
The statutory command matters. Once a competent officer lawfully commands dispersal, members have a duty to disperse. If they refuse, or their conduct itself shows a determination not to disperse, the authorised officer may use force and make necessary arrests for dispersal or lawful punishment.
Competent authority
An Executive Magistrate, officer in charge of a police station or, in that officer's absence, a police officer not below sub-inspector may issue the Section 148 command.
Two covered assemblies
The provision applies to an unlawful assembly and to an assembly of at least five persons likely to disturb public peace. The second category still requires an objective likelihood, not a bare preference against gatherings.
Civilian assistance
If force becomes lawful, the authorised officer may require assistance from persons other than serving members or officers of the armed forces. Their action remains tied to dispersal and necessary arrest or confinement.
Arrest is not punishment
Confinement during dispersal does not decide guilt for unlawful assembly, rioting or another offence. Any prosecution must still establish the relevant offence and individual participation through ordinary criminal process.
When can armed forces be used to disperse an assembly?
Sections 149 and 150 reserve armed-force intervention for public-security situations where ordinary dispersal is inadequate or a Magistrate cannot be reached.
Magistrate-led requisition
If an assembly covered by Section 148 cannot otherwise be dispersed and public security requires dispersal, the District Magistrate or an authorised Executive Magistrate who is present may call upon armed forces under Section 149.
Minimum force rule
The commanding officer must use as little force and cause as little injury to persons and property as is consistent with dispersal and necessary arrest. This express rule reflects necessity and proportionality.
Emergency without a Magistrate
A commissioned or gazetted armed-force officer may act under Section 150 only when public security is manifestly endangered and no Executive Magistrate can be contacted. Once communication becomes practicable, the officer must seek and follow the Magistrate's instructions.
Escalation must be reasoned
Warnings, avenues to disperse, crowd composition, vulnerable persons, available alternatives and the immediacy of violence all inform whether the chosen level of force was genuinely necessary.
How do constitutional rights limit crowd-control force?
Public order may justify restrictions, but the State must balance peaceful expression, life and bodily integrity with the rights and safety of others.
Articles 19(1)(a) and 19(1)(b) protect expression and peaceful assembly, while Article 19(3) permits reasonable restrictions in the interests of sovereignty, integrity and public order. Article 21 requires fair, just and proportionate State action where life or physical liberty is at stake.
Differentiate peaceful and violent actors
An authority should not treat every participant as violent merely because some persons offend. Individual conduct, practical feasibility and the developing threat must shape warnings, arrest and force.
Least harmful effective response
The question is not whether some force was available, but whether the chosen force was needed, suitable and no more harmful than reasonably required to restore public order.
Section 151 protection
Prosecution for acts purportedly done under Sections 148 to 150 requires Central Government sanction for armed-force personnel and State Government sanction in other cases. Good-faith statutory acts receive protection, but the text does not validate bad faith or force outside the power.
Evidence and review
Contemporaneous orders, video, medical records, deployment logs, warnings and casualty records help a court test good faith, necessity and proportionality. Constitutional compensation or other review may remain available even where criminal prosecution has a sanction requirement.
Leading cases and what they establish
Read each authority for the proposition it proves, the legal question it answers and the reasoning that supports the result.
In Re: Ramlila Maidan Incident
(2012) 5 SCC 1
Held: Crowd-control action must balance public duty with speech, peaceful assembly and life. The perceived threat, immediate need and restraint imposed must be reasonable, bona fide and proportionate.
Why it matters: Use it to test night-time dispersal, inadequate warning, indiscriminate force and compensation for rights violations.
Read the judgmentAnita Thakur v. Government of Jammu and Kashmir
(2016) 15 SCC 525
Held: Police may use reasonable force to control an unlawful or violent assembly, but excessive force against persons who are fleeing or no longer threatening order can violate fundamental rights and justify compensation.
Why it matters: Use it to distinguish legitimate dispersal from force that continues after the necessity has ended.
Mazdoor Kisan Shakti Sangathan v. Union of India
(2018) 17 SCC 324
Held: Peaceful protest is constitutionally protected, while regulation may balance protest rights with residents, movement and public order. Balancing cannot totally extinguish one side's rights.
Why it matters: Use it to frame lawful regulation before deciding whether coercive dispersal is justified.

A clear answer sequence
- Begin with the Article 19 right to peaceful assembly and its public-order limitation.
- Classify the gathering under Section 148 and identify the competent authority.
- Ask whether a lawful command, refusal or determined non-dispersal preceded force.
- For armed forces, apply the higher thresholds and the express minimum-force rule in Sections 149 and 150.
- Conclude on proportionality, Section 151 sanction and available constitutional or criminal accountability.
Points that are often confused
- Assuming every gathering of five persons may be dispersed by force.
- Treating a dispersal command as proof of each participant's criminal guilt.
- Skipping the civil-force and armed-force escalation sequence.
- Reading prosecution sanction as immunity for every use of force.

Rules to retain
- Section 148 covers unlawful assemblies and five-person assemblies likely to disturb public peace.
- A command to disperse ordinarily precedes force unless conduct shows a determination not to disperse.
- Section 149 requires inability to disperse otherwise and necessity for public security.
- Armed forces must use as little force and injury as consistent with the lawful purpose.
- Articles 19 and 21 require necessity, proportionality and meaningful accountability.
Questions to test understanding
- Who may issue a Section 148 command?
- What additional conditions precede use of armed forces?
- Why does Section 151 not end every accountability inquiry?
Questions students ask
Can police disperse any assembly of five or more people?
No. Section 148 requires either an unlawful assembly or an assembly of five or more persons likely to disturb public peace. A peaceful gathering is not removable merely because of its size, message or inconvenience.
Must police always warn the assembly before using force?
Section 148 is structured around a command to disperse, but it also covers conduct that itself demonstrates a determination not to disperse. In either setting, necessity, feasibility of warning and proportionality remain central to review.
Does government sanction under Section 151 legalise excessive force?
No. Sanction is a threshold for instituting specified criminal prosecution. It does not transform bad faith, unnecessary force or conduct outside Sections 148 to 150 into a lawful act, nor does it automatically exclude constitutional review.
