Organized squatters can claim land ownership

Here's a nifty trick. Mumbai's squatters actually have the right to force the government to give them the land they live on, as long as 70% of them come to the table and agree. It's all in a 1976 law that most people have forgotten. That's what architect Chandrashekhar Prabhu tells The Hindu Business Line. If this is true, it's a bloody scandal that more communities haven't petitioned the government for land. Does anyone out there know anything more about this?
