Use of common wall of a flat in an apartment

Discuss the issues with your other neighbours / RWA / MC members and sort out amicably. 

However, even then if he is not mending, issue notice through a local lawyer. 

The facts posted suggest that the fixtures (and their use and disturabance) has been complaining of, had been pre-existing when you made the purchase. As such, there appears to be no remedy {if at all any required} than to introspect yourself.

The author has made it amply clear that the common wall (living room of author) has been cut to put granite and tiles loosing its strength (now) i.e., much later than the premises was handed over possession by builder.

Experts may kindly go through contents of query once again.

I reiterate my opinion and advise the author to discuss with his neighbour(s) / RWA / Managing Committee for amicable solution before filing a suit for permanent injunction and / or police complaint. 

Yes, in view of the clarification from the author, he can pursue the remedy if he is really inconvenienced and/or the fixture would have adverse effect on the wall in the long run. He may get expert opinion and pursue the modes for amicably settling the issue before approaching the court. The civil action in tort lies.
