Supreme Court won't hear Calif. human waste case

The U.S. Supreme Court has decided not to step into a legal spat over poop.

The nation's highest court said Tuesday that it won't rule on Kern County's ban of dumping human waste on its fields.

Los Angeles and the sanitation districts of Orange County, which have been hauling sludge to those fields for use as fertilizer, claim the ban violates federal interstate commerce laws and California recycling laws.

The case will go back to a lower federal court.
