The bill, initially introduced by California assemblyman Leland Yee, was signed into law in 2005 by governor Arnold Schwarzenegger. The Entertainment Software Association (ESA) quickly sued the state, and a district judge blocked the law on the grounds of First Amendment protection.

A federal judge ruled that the law was unconstitutional in August of 2007. The state of California appealed the decision, leading to another rejection in February of this year by the U.S. 9th Circuit Court of Appeals. Now the Supreme Court could choose to make a final ruling.

Proponents of the law argue a link between violent games and real-world violence. However, in his 2007 ruling, District Judge Ronald Whyte stated that "the evidence does not establish that video games, because of their interactive nature or otherwise, are any more harmful than violent television, movies, internet sites or other speech-related exposures."

Schwarzenneger maintains that the law can only help parents to better protect their children from violent media.

"By prohibiting the sale of violent video games to children under the age of 18 and requiring these games to be clearly labeled, this law would allow parents to make better informed decisions for their kids," said the Governator.

Added Schwarzenneger in a recorded statement: "Stop whining, you son of a bitch!"

The Supreme Court's decision could be known as soon as Wednesday.
