Illegal Marriage Halls & Noise Pollution

Hello. I live in sector 52 noida. just behind my apartments are 2 marriage halls - FM Gardens & Olive Garden. There is a function here almost daily and the DJs are extremely loud (We all know, no DJ follows the court rulings of 65db during the day) Then there are dhols, drums etc. Also, i believe that these gardens are encroachments and built on space dedicated for green belt (See noita authority map) and check the location of olive garden sector 52, noida / fm garden sector 52 noida. I would like to know the following 1. What is the process to check if these marriage halls are illegal or an encroachment on green belt. If yes, how do we proceed. 2. If all the papers for these are in place, even then, there was a ruling by UP high court banning all use of DJ in the state, which was then put on stay by the honorable Supreme Court. How can we pursue that case. It is high time we all understand that DJs (whether used in marriages or godly processions or other gathering) are high level tortures & they need to be curbed. If one is willing to fight against these, what is the best way to go about it.
