We write to follow up on our request in January 2006 that the SEC impose sanctions on the Chevron Corporation for violations of its disclosure obligations regarding its liability for creating a large oil-related environmental catastrophe in the Amazon rainforest of Ecuador... Despite privately admitting to a U.S. government agency that it faces an extraordinary liability that could surpass $10 billion..., Chevron has continued to flout its disclosure obligations... [T]his situation cannot be tolerated further without the imposition of a penalty on Chevron for failing to comply with its obligations. It is beyond doubt that Chevron’s legal position in the litigation...has deteriorated significantly since our last contact.
