The Iowa Supreme Court has dismissed a lawsuit brought by Iowa Citizens for Community Improvement and Food & Water Watch seeking to compel farmers to reduce levels of nitrogen and phosphorus in the raccoon river. Overturning a lower court ruling, the court held that the plaintiffs did not adequately demonstrate a concrete injury to establish standing, and that “plaintiffs’ effort to repurpose the historically narrow public trust doctrine to solve a complex environmental problem presents a nonjusticiable political question.”
