Next, all I can say is that half knowledge is dangerous. And arguments for argument's sake is a waste of time. Please get a good lawyer. If I need advice in technology, I shall surely come to you.

I say again none of the writs apply in this case. I do not question the knowledge of competence of any body.

Also go thru RERA and rules notified by your state under RERA.
