The summons was issued by the court of Chief Judicial Magistrate Pankaj Singh Maheshwari on the petition filed by the Bhopal Group for Information and Action (BGIA) and other NGOs fighting for the rights of poison gas victims.
The petition was filed to seeking to force Dow Chemicals to admit its alleged criminal liability in the case since Union Carbide Corporation (UCC) is now a wholly-owned subsidiary of the multinational chemical major.
The court has also directed the Central Bureau of Investigation (CBI) to ensure that summons is served to Dow Chemicals in the United States of America through the Union Ministry of External Affairs.
Meanwhile, a release issued by Amnesty International from its London office said "the time has come for Dow Chemicals to appear in an Indian court and account for the failure of its wholly-owned subsidiary, Union Carbide, to respond to criminal charges against it".
Quoting Amnesty International's Director for Global Issues Audrey Gaughran, the release said that "refusing to comply with the court's summons would be to treat the Indian justice system with contempt, undermining Dow's credibility as an investor in India".
