LLM Group 6 Environment and Legal Order Prevention and Control of Pollution 2016 Question Paper with Solutions

For full marks, cover: two tasks. "Describe" the sources and effects, so classify the sources by where noise is made and describe each class, then describe the effects on hearing, on the body and mind, on vulnerable groups and on society. The second task is weightier: "elaborate the need" means showing, instrument by instrument, what the present patchwork of Indian law cannot do, comparing what specific noise statutes elsewhere provide, and drawing the need out of that comparison, with the judicial observations that support it.

Noise and noise pollution

In Free Legal Aid Cell Shri Sugan Chand Aggarwal v. Government of NCT of Delhi, AIR 2001 Del 455, decided on 23 July 2001, the Delhi High Court said that noise pollution simply connotes unwanted sound in the atmosphere: noise is sound, but it becomes pollution when the effects of the sound become undesirable. Any sound may be noise if circumstances make it disturbing, so the law looks at the level, the hour and the place, and at the harm done to people who have not chosen to hear it.

Transport. Engines, exhaust systems and tyres make road traffic the most widespread source, and the Supreme Court noted that narrow streets and tall buildings create a canyon in which traffic noise reverberates. Horns add a sharper element: in M.S. Appa Rao v. Government of Tamil Nadu, (1995) 1 LW 319, the Madras High Court directed the Director-General of Police to impose a total ban on horn-type loudspeakers and air horns on automobiles. Aircraft, including low-flying aircraft, and railways, with their engines, whistles and shunting yards, affect the communities around them.

Industry and work. Machines working at high speed make factories intensely noisy inside, and fans, motors and compressors on their walls disturb neighbours outside. The Supreme Court recorded that the Factories Act, 1948 contains no specific provision on noise, although noise-induced hearing loss appears in its Third Schedule as a notifiable disease that a medical practitioner must report.

Construction. Pneumatic hammers, air compressors, bulldozers, loaders, dump trucks and pavement breakers are major contributors to urban noise, and they operate close to homes, schools and hospitals.

The effects described

Auditory effects. High and continuous sound damages hearing. Short exposure causes a temporary loss that recovers; prolonged exposure causes permanent loss. The Supreme Court recorded that the risk of hearing loss is negligible only below 75 dB(A) Leq over eight hours.

The list the Supreme Court gave. In Church of God the Court said noise may cause interruption of sleep, interference with communication, loss of efficiency, hearing loss or deafness, high blood pressure, depression, irritability, fatigue, gastrointestinal problems, allergy, distraction, mental stress and annoyance. It added that noise affects animals alike, that the damage depends on the duration and intensity of the noise, and that noise sometimes leads to serious law and order problems.

Effects on sleep and behaviour. In Burrabazar the Calcutta High Court noted research that bad night sleep causes mood changes, reduced cardiovascular performance and poor performance at intellectual and mechanical tasks, and a recommendation that sound in sleeping quarters at night should not exceed 45 dB(A). It noted that loud noise increases anxiety and aggression, an effect that may persist outside the noisy place.

The Environment (Protection) Act, 1986 and the Noise Rules. The Rules supply ambient standards, restrictions on loudspeakers, horns, firecrackers and construction equipment, and complaint and prohibition procedures. But they are subordinate legislation, enforced by police officers and magistrates without technical resources, and they reach a violator's pocket only through a penalty under section 15 of the Act imposed by an adjudicating officer.

The Motor Vehicles Act, 1988. Section 194F imposes a fine of one thousand rupees, two thousand for a repeat, for sounding a horn needlessly or where a sign prohibits it, and section 190(2) punishes driving a vehicle that violates the noise standards. The Jan Vishwas (Amendment of Provisions) Act, 2026 has enacted, subject to notification, a recorded warning for a first contravention of both. These provisions reach only vehicles.

The criminal law. Public nuisance under section 270 of the Bharatiya Nyaya Sanhita, 2023 is punishable under section 292 with a fine of up to one thousand rupees. Sections 152 and 163 of the Bharatiya Nagarik Suraksha Sanhita, 2023 let a magistrate order a nuisance removed or, in urgent cases, direct a person to abstain from an act, but an order under section 163 lapses after two months unless the State Government extends it.

United States. Federal law declared a policy of promoting an environment free from noise that jeopardises health or welfare, and provided for identifying major noise sources, noise emission standards for products in commerce, labelling, and the development of low-noise products.

Japan. Its Noise Regulation Law let the Prefectural Governor designate residential, school and hospital areas, required persons installing specified facilities to report within thirty days and those starting specified construction to report seven days in advance, and made the Governor responsible for monitoring noise levels.

China. Its law of 1996 fixed national noise limits, forbade the manufacture, sale or import of vehicles exceeding them, banned high-pitch loudspeakers where noise-sensitive buildings are concentrated, and gave every victim of noise the right to demand that the polluter eliminate the hazard and to compensation for loss.

Four: a remedy for the person harmed. The Delhi High Court observed in Free Legal Aid Cell that environmental laws have failed to afford sufficient remedies to individual sufferers and that the criminal liability they create is of little avail to victims. A noise statute can give victims a right to have the hazard removed and to be compensated, as the Chinese law did.

Five: durability. Rules can be altered by notification, as the silence zone amendment of 10 August 2017 showed. An Act of Parliament fixes the core protections, such as night-time limits and protected zones, beyond executive revision.

Six: an end to legislation by the courts. In Burrabazar the Calcutta High Court said that the legislature may not rise to the occasion but the court will not keep its hands folded, and in In re Noise Pollution (V) the Supreme Court issued guidelines under Articles 141 and 142 to remain in force until superseded by appropriate legislation. It said India needs one simple but specific and detailed law on noise pollution. Judicial directions are a stopgap, and their own terms invite Parliament to act.
