As per Provision of the Article 19(2) of the Indian Constitution :
Every citizen has the right to assemble peaceably and without arms. It includes the right to hold public meetings, demonstrations and take out processions. This freedom can be exercised only on public land and the assembly must be peaceful and unarmed. This provision does not protect violent, disorderly, riotous assemblies, or one that causes breach of public peace or one that involves arms. This right does not include the right to strike.
The State can impose reasonable restrictions on the exercise of right of assembly on two grounds, namely, sovereignty and integrity of India and public order including the maintenance of traffic in the area concerned.
Under Section 144 of Criminal Procedure Code (1973), a magistrate can restrain an assembly, meeting or procession if there is a risk of obstruction, annoyance or danger to human life, health or safety or a disturbance of the public tranquillity or a riot or any affray.
