Earlier on Monday, eight accused, one of whom is deceased, were sentenced to two years in prison for causing death due to negligence.
Reacting to the development, representatives of the tragedy's victims and their families who have been protesting outside the court, said they would approach the Madhya Pradesh High Court to allow the slapping of more stringent charges against all those accused in the case.
The Magistrate court in Bhopal on Monday convicted all eight Indians accused in the 1984 Bhopal gas tragedy case. A Rs 500,000 fine has been imposed on UCIL.
Toxic gas leak from a Union Carbide pesticide factory in 1984 killed thousands and left an unspecified number battered with diseases and deformity - the toll of victims is still rising.
Despite Monday's conviction, there is little closure for victims. Legal experts have alleged that there was an attempt to cover up the case. It took the CBI three long years to file a chargesheet that many believed was weak. Then in 1996 the charges were watered down making all sections carry the maximum punishment of 2 years.
The charges were also all bailable and with the prime accused in the case - former Union Carbide (USA) chairman Warren Anderson still on the run and unlikely to present himself in Indian court, there is little hope that justice will be served.
