As an outside party, the ECA will submit an amicus brief in the case and has set up a website for a petition and more information about the pending arguments. So far, lower courts have judged the proposed law, which would set up legal rules and penalties against selling violent video games to minors, to be unconstitutional. Of course, this time around, we're talking about the United States Supreme Court, so any decision in favor of the bill would overturn previous rulings in lesser courts. Take that, Ninth Circuit Court of Appeals!
Oral arguments in the case begin November 2, and the judges should have a decision soon after that. This will be the first time the Supreme Court looks at video games and the First Amendment, so a ruling either way should be pretty historic.
