1.

K.K.R. Majestic Colony Welfare Association (2000 (3) KLT 651 (SC). R.3(1) of the Noise Pollution (Regulation and Control) Rules, 2000 provides for the ambient air quality standards in respect of noise for different areas/zones as specified in the schedule annexed to the Rules. Responsibility as to the enforcement of noise pollution control measures has been narrated therein. So also, its consequence. The principle laid down by the apex court was followed by a Bench of this Court in W.A. 3125 of 2001 and the following directions were issued.

"We, therefore, dispose of the writ appeal and the original petition by directing the State of Kerala, the first respondent, to take necessary steps to identify the zones and generally to fulfil all the requirements of R.3 of the Noise Pollution (Regulation and Control) Rules, 2000 within six months from this date. The defined authority under the Rules will, thereafter, be entitled to consider the application for use of loud speakers and permit them strictly in terms of the said Rules and the identification of the zones. The State and the authorities under it, including the Pollution Control Board, will continue to enforce the directions issued by the Deputy Inspector General of Police in the circular dated 22-7-2000 until the required exercise under the Noise Pollution (Regulation and Control) Rules, 2000 is undertaken by the State Government.

It is a matter of serious concern that Environmental Protection laws are not properly implemented and / or enforced by the various authorities and officers of the State including the Pollution Control Board. The State Government is directed to ensure that its officers, the Local Authorities and the Pollution Control Board strictly implement the Environmental Protection Laws, Rules, Regulations and notifications and to take strong action against those who do not implement them strictly and in consonance with the spirit of such laws."

World Health Organisation in its report on human health has stated as follows:
