Expect legal view on HZL share sale in a month: Govt

"We feel that under this proposal of buying of shares although shareholding pattern will not change but it may amount to change in the status quo. So that is why we are taking a legal opinion on this issue," Kumar said.

When asked when is the legal opinion expected, the secretary said that "may be (it may take) about a month." In 2002, the government sold 26 percent stake in HZL for Rs 445 crore to billionaire Anil Agarwal-led Vedanta. The firm also acquired 20 percent stake from the public. In 2003, it again acquired an additional 18.92 percent in exercise of call option clause in shareholders agreement between the government and the firm.

The government now owns 29.54 percent in HZL.

In October last year HZL CEO Sunil Duggal had said that there have been no talks on buy-back of the government's shares in the integrated zinc producer.

Chairman of mining giant Vedanta Resources, Anil Agarwal has time and again evinced interest in acquiring the government's remaining stake in HZL and aluminium maker Balco.

Earlier, Agarwal had said that stake sale of the government's remaining share in HZL and aluminium maker Balco can fetch it Rs 25,000 crore.

In a setback to the government, the Supreme Court had earlier restrained it from going ahead with any further disinvestment of its minority share in HZL, the management of which is under the control of a Vedanta subsidiary.
