My neighbor in Kolkata plays loud music all night can I file a case for nuisance

A civil suit for nuisance can be filed before the court in Kolkata seeking a permanent injunction restraining your neighbor from causing noise pollution. You can also file a complaint before the Magistrate under Section 268 BNSS for public nuisance, as noise pollution is a criminal offense. Under West Bengal Premises Tenancy Act 1997, there may be specific noise pollution rules applicable in residential areas of West Bengal. You should record the noise levels with a decibel meter and maintain a log of the timings as evidence. If the authorities do not act on your complaint, you can approach the Calcutta High Court under Article 226 for appropriate directions.
