The Calcutta High Court on Friday rejected all petitions challenging the acquisition of land at Singur for the Tata Motors’ small car plant.

The High Court said that there are no illegalities in the land acquisition.

The verdict comes a week after Ratan Tata unveiled the people’s car, Nano at an auto expo in New Delhi.

Earlier, petitioner Joydeep Mukherjee had moved the writ petition on February 9, 2007 challenging acquisition of the 997.11 acre at Singur in Hooghly district, about 40 km from the metropolis.
