The Calcutta High Court has set aside as constitutionally invalid the legislation introduced by Mamta Banerjee government in West Bengal to recover land leased to Tata Motors in Singur for its small car project.

A division bench comprising Justices Pinaki Chandra Ghosh and Mrinal Kanti Chaudhury observed that President's assent had not been taken for the Singur Land Rehabilitation and Development Act 2011 Act which empowered her Government to take back 400 acres of land from Tata Motors for the Nano small car project. The court observed that what was done in Singur was acquisition of land by the said Act and as such it was void and unconstitutional.

The implementation of the order was, however, stayed for two months by the division bench to allow the aggrieved party to appeal to the Supreme Court.

The division bench set aside the order of Justice I P Mukerji who had held the Act to be constitutional.
