As far as eye can see, there are mounds of wood, tin and tarpaulin, the remains of 6,200 illegal homes, flattened by a heavy excavator running on tank-like tracks and giant motorised claws. ‘‘Such a demolition has never happened before in the state,’’ said Deputy Municipal Commissioner V M Kalam Patil, surveying the end of the sprawling slum of Malvani in the western suburb of Malad. As stunned families of painters, taxi drivers, vegetable vendors and others from Mumbai’s blue-collar workforce watched after a day of anger and hurling stones, Patil explained that 39,000 shanties (target: 44,000 slums, all built after the cut-off date of 1995) were now flattened since the city’s biggest ever demolition drive began 18 days ago. Across town at the Brihanmumbai Municipal Corporation (BMC)—after instructions from Deputy Chief Minister R R Patil— officers were hastily preparing to balance the demolitions by planning action against illegal constructions by builders and shopkeepers. ‘‘In a week, we will have the list of all illegal constructions throughout the city,’’ Municipal Commissioner Johny Joseph told The Indian Express.
