TATA should pay market price to farmers. Since TATA's interest has increase the price of land itself at Singur, TATA should pay the new market price.
TATA bought Corus for twice the price than its market capitalization last year and paid about 4 bn $ more than their first offer.
Why cannot TATA pay about 50-100 crore more for land to the farmers?
Let there be free market forces, and CPI-M state government be neutral mediator to protect rights of both parties rather than enforcement of land acquisition.
Farmers should have a choice to sell their land to the highest bidder, or not sell their land at all if they so wish.
The framework at Singur is incorrect and against the rights of the farmers there.
