The Calcutta High Court has upheld the Singur Land Rehabilitation and development Act, 2011 as constitutional and valid. The Calcutta High Court pronounced its verdict on a plea filed by Tata Motors, challenging the constitutional validity of the legislation. The Supreme Court, on an appeal from Tata Motors, had stayed distribution of the land of the disputed factory site until further orders from the High Court.

Soon after coming to the power in the state, the Mamta Banerjee government passed the Singur Land Rehabilitation and Development Act 2011. On June 22 it took over possession of the land on which Tata Motors had started construction before moving to Sanand in Gujarat. On the next day, Tata Motors moved High Court, challengening the legality of the Act.

Tata Motors sought an interim stay from High Court, when the government announced the plan to start distribution of land to the landlosers on the basis of the enacted legislation. When this move was unsuccessful, the company moved an SLP before Supreme Court. The apex court, while ordering an interim stay on the ditribution of land, urged the Calcutta High Court to complete the hearing on the issue.
