Chevron's 'sour grapes' over Ecuador ruling

Steven Donziger, the lawyer who has waged a two-decade battle against Chevron Corp over pollution in the Amazonian jungle in Ecuador, is not one to accept defeat quietly.

Hours after a federal judge in New York ruled on Tuesday that he had used bribery and fraud to secure a $9.5 billion judgment against the oil company in Ecuador in 2011, Donziger promised to appeal and said this was a case of 'sour grapes'.
