The U.S. Supreme Court ruled 5-4 against Apple on Monday on a case involving whether or not a group of iPhone users will be allowed to bring an antitrust lawsuit against the company regarding its App Store practices. The iPhone owners allege that Apple’s 30 percent commission on App Store sales is passed along to users, representing an unlawful and unfair use of Apple’s monopoly power.

Apple had moved to have the case dismissed, arguing that consumers were buying their apps from the developers — not from Apple. And it was the developers who were setting the prices. The court disagreed, saying that Apple contracts with the third-party developers to sell the 2 million apps that are live today on its App Store, keeping its 30 percent commission on every sale along the way.
