Children in California who want to buy or rent a violent video game without a parent’s permission could have that right taken away by a federal appeals panel, which heard arguments on the case Wednesday. A state law passed in 2005 that tries to limit access to such games is under consideration by a three-judge panel of the 9th U.S. Circuit Court of Appeals. The state law, which prohibits the sale or rental of the games to anyone under 18 and requires them to be clearly labeled, was struck down last year by a lower court.
