Ford Motor Co. and other defendants in a suit over landfill contamination can’t claim they were akin to “federal officers” in their efforts to comply with consent orders to remediate a Superfund site, a federal judge says.

In remanding a suit back to state court, U.S. District Judge Joel Pisano, of the New Jersey District, rebuffed Ford’s attempt to avail itself of a statute that allows suits against U.S. agency officials and those acting under them to be removed to federal court.
