A divided federal appeals court has dealt the federal government a significant setback in its prosecution of Barry Bonds on perjury charges. The 9th U.S. Circuit Court of Appeals ruled Friday that prosecutors may not present positive urine samples and other vital evidence that the government says shows that the slugger knowingly used steroids.
