Des Moines Register: The Iowa Supreme Court stopped a lawsuit that claimed the state has failed to adequately protect the public’s interest in the Raccoon River, a major water source for the Des Moines metro area, saying the suit raised political questions that lawmakers, not the courts, should decide. “We … leave this dispute where it stands at present: with the branches of our government whose duty it is to represent the public,” the Supreme Court said in its 4-3 decision today. “In the end, we believe it would exceed our institutional role to ‘hold the state accountable to the public.'”
