Frustrated residents of a Denver suburb say state law is forcing them to participate in a major oil and gas drilling project against their wishes, so they launched legal challenges with potentially significant consequences for the industry. Backed by a federal judge, they have a chance this week to ask state regulators to block multiple wells planned within about 1,300 feet of homes in the city of Broomfield.
