The concept of Law & Order is an administrative and constitutional concept, referring to the enforcement of laws and regulations to ensure justice, uphold legal norms, and maintain peace within society. Its basic structure and the police system are rooted in the colonial-era Police Act of 1861 and the criminal codes established by the British in the 1860s.
In India's federal structure, the maintenance of Law & Order is primarily the responsibility of the State Governments. This is because 'Police' (Entry 2) and 'Public Order' (Entry 1) are explicitly listed as subjects in the State List of the Seventh Schedule to the Constitution of India. State Governments have the primary duty to prevent, detect, and investigate crime. The Union Government, through the Ministry of Home Affairs (MHA), plays an advisory and coordinating role, providing financial assistance for police modernization and sharing intelligence inputs. However, Article 257 allows the Central Government to deploy its own security forces to a state upon request to aid in maintaining order.
An informed reader must distinguish Law & Order from Public Order, a distinction clarified by the Supreme Court in cases like Ram Manohar Lohia v. State of Bihar (1966). Law & Order is the wider concept; a breach of it, such as a simple theft, affects only a few individuals. Public Order is a narrower, "concentric circle" within it, where the disturbance must affect the community or the public at large, disrupting the "even tempo of the life of the community". This distinction was recently reiterated in Banka Sneha Sheela v. State of Telangana (2021), where the Court held that mere contravention of law affects 'law and order' but not necessarily 'public order'. The core legal frameworks connected to this are the Indian Penal Code (IPC) and the Code of Criminal Procedure (Cr.PC).
