The federal government was back in court Monday, arguing that the lawsuits asking the U.S. government to fix cross-border sewage flows should be thrown out. The Department of Justice is trying, for the second time, to have three cross-border sewage lawsuits thrown out before they get to trial. Imperial Beach, Chula Vista and the port of San Diego filed the first lawsuit. SurfRider’s San Diego chapter filed the second. And the state of California filed the third.
