West Bengal CM Mamata Banerjee on Tuesday held a meeting with the state law minister Moloy Ghatak and other legal aides to decide on the mode of appeal against an arbitration panel order directing the West Bengal Industrial Development Corp (WBIDC) to pay Tata Motors Rs 766 crore as compensation over losses incurred due to the scrapping of its car factory in Singur. ​​The state is mulling whether to challenge the order in the Calcutta high court or move the Supreme Court directly.
