A federal appeals court has agreed to< rehear a lawsuit over an Alameda County ordinance that banned guns and ammunition on public property.

The 9th U.S. Circuit Court of Appeals issued an order on Monday calling for an 11-judge panel to hear the case.

A three-judge panel of the same court upheld the gun ban in May although it did give opponents a chance to rewrite their lawsuit in light of recent U.S. Supreme Court rulings confirming gun ownership as a fundamental right.

The county's ordinance -- enacted in 1999 -- effectively shut down gun shows at the county fairgrounds. It prompted a lawsuit by gun show promoters Russell and Sallie Nordyke, who said the law violated their Second Amendment rights.
