The court said Vedanta employees could enter the smelter premises for "administrative purposes" but the company was not allowed to resume operations.

The court was hearing Vedanta's request to reopen the plant and the hearing will resume on Aug. 20.

The government of the southern state of Tamil Nadu ordered the permanent closure of the Thoothukudi plant and disconnected its power supply in May, saying the plant was polluting.

Its decision followed protests that turned violent, culminating in police firing on protesters, killing 13 of them. The protesters had demanded a permanent shutdown of the plant, which they said was causing air and water pollution.

Vedanta has said the protests were based on false notions and that the plant was closed due to "political considerations and to appease the public protests."
