The tenants are the petitioners before me. In H.R.C.

While filing the application, he gave the undertaking required of him by section 14 (2) (b) of the Act stating that the work of demolition of the material portion of the building would be substantially commenced by him not later than one month and would be completed before the expiry of three months from the date he recovers possession of the entire building.
