The Bhopal judicial saga has still not offered a dignified solution for victims of the tragedy after more than three decades of litigation. This issue shows paradigmatically the severe limitations of human rights and environmental international law to control and hold accountable transnational corporations. Massive and on-going disasters like this caused by Union Carbide, show that neither the Ruggie’s Guiding Principles on Business and Human Rights, nor the rhetorical mantra of sustainable development can contribute to tackle the vicious circle of impunity. That is why it is necessary to reach a consensus in order to stablish a binding international treaty on the subject that can effectively prevent and punish acts such as those committed in Bhopal.
