Imla malik right against builder and tenant

This discussion concerns the rights of an 'Imla Malik' (original owner) who sold a property in Borivali before 2000. Despite the sale, the builder has failed to develop the property and has instead placed it under SRA. The original owner is seeking clarification on their rights against both the builder and existing tenants, especially as the builder had promised an extra flat in the agreement. They are also questioning if they can hire a new builder and are facing challenges from tenants who claim they have no rights.
