The lawsuit is backed by indigenous groups and settlers in the region around Lago Agrio, in northeastern Ecuador, supported by a coalition of non-governmental organisations, including the US-based NGOs Amazon Watch and Rainforest Action Network.

The NGOs said the ruling “once again proves that the company is responsible for deliberately dumping billions of gallons of toxic waste sludge into local streams and rivers, which thousands depend on for drinking, bathing, and fishing, and created a public health crisis in the rainforest region”.
