US Democrat Frank Pallone and 10 other Congress lawmakers have filed an amicus brief in a US Court of Appeals on behalf of the more than 20,000 victims of the Union Carbide chemical disaster at Bhopal in 1984..."It is... a mandate of the Congress to ensure that US corporations and companies investing abroad or undertaking activities overseas comply with local, national and international laws regarding the environment and do not engage in environmental abuses," they said in the amicus brief...Pallone’s office noted that victims have filed numerous lawsuits against the company [Union Carbide, now part of Dow] over the past two decades...but their claims have remained unanswered so far.
