A Brazilian judge moved two $11 billion civil cases against Chevron and drilling-rig operator Transocean related to an offshore drilling accident and spills to a different court in Rio de Janeiro, a decision that removes a crusading prosecutor from the cases. The momentum is shifting in the legal battle stemming from a rupture in November at a well that Transocean was drilling in the Frade field, which Chevron operates. The latest development, published in a court filing on Friday, comes on the heels of another decision in favor of the companies earlier this week from a separate court, in which a judge denied a request to bar the two companies from operating in Brazil. Eduardo Santos de Oliveira, a federal prosecutor based in the interior of Rio de Janeiro state, filed two 20 billion reais ($11 billion) lawsuits against U.S. oil company Chevron and its contractor Transocean after a November spill of 2,400 to 3,000 barrels and a related March seep in the same field. Friday\'s decision to move the two civil cases does not change the content of the charges, but it removes the cases from Oliveira\'s turf and hands them to another team of prosecutors. The decision did not address the criminal charges that Oliveira also brought against the companies and 17 of their employees that could carry jail sentences up to 31 years. Oliveira told Reuters he will appeal the decision. \"I remain convinced that they should be prosecuted here close to where the crimes occurred,\" he said. Judge Tiago Pereira Macaciel said in a court filing released on Friday that \"the magnitude of the environmental damage exceeds the area subject to the competency of Campos ... making it a regional damage.\" Chevron Corp\'s head of media relations, Kurt Glaubitz, said Chevron Brasil Upstream Frade Ltd, its local subsidiary, was pleased with the court\'s decision. Guy Cantwell, communications chief for Transocean, said by email that the company also questioned the validity of a second civil lawsuit, saying the charges lacked technical grounds. Chevron owns 52 percent of the Frade field, Brazil\'s state-led oil company Petrobras owns 30 percent and a Japanese group led by Inpex Corp and Sojitz Corp owns 18 percent.
