Hi Rajesh, Since the developer has failed to allow you free user of the common area, you can file case for damages against him in the consumer forum as well.
Hi Rajesh, No construction whatsoever can be carried out on the common area without the consent of the other co-owners. If any construction is commenced or you apprehend that construction may be started without the consent of other co-owners then you may move to court to seek an immediate stay order against the construction.
