The Ecuadorean judge presiding over a $27 billion environmental lawsuit against Chevron recused himself Friday amid an investigation into allegations of wrongdoing.

Earlier in the week, Chevron released three video recordings in which provincial Judge Juan Evangelista Nunez allegedly told two businessmen — an Ecuadorean with ties to Chevron, Diego Borja, and an American businessman, Wayne Hansen — that he had already made up his mind to rule against the company.
