The United States Supreme Court is scheduled to address an appeal of a Californian videogame law tomorrow, September 29.

Entertainment Merchants Association v. Schwarzenegger (formerly known as The Video Software Dealers Association (VSDA) v. Schwarzenegger), revolves around a Californian law that banned the sale of certain videogames to anyone under 18 years of age. First signed into law by Schwarzenegger in 2005, the law was rejected again in February of 2009 by the 9th Circuit Court of California, which upheld an earlier 2007 ruling that deemed the law unconstitutional.

Schwarzenegger and California Attorney General Jerry Brown appealed to the Supreme Court in May of this year, marking the first time a case involving the restriction of violent game sales to minors has ever been considered by the top court of the United States.

As part of the proceedings, The Supreme Court will also decide whether to accept the amicus brief filed by California State Senator Leland Yee (D) in July of 2009. In the brief, Lee, who authored the original statute at the center of the whole case, argues why the Supreme Court should approve the state of California’s petition for a full hearing. He was supported in the brief by the California Psychiatric and California Psychological Associations.

The Supreme Court’s decision could take a few days or more. A final decision should be made public by next Monday, October 5.

Update: Just to clarify, The Supreme Court did consider a similar topic when ruling on American Amusement Machine Association et al. v Kendrick et al. in 2001, when it denied the City of Indianapolis' petition for certiorari. That case centered on an attempt by the city to limit the display and operation of currency-based machines deemed harmful to minors.
