The U.S. Supreme Court on Monday ruled in favor of Microsoft Corp in its bid to

fend off class action claims by Xbox 360 owners who said the popular video game console gouges discs because of a design defect.

The court, in a 8-0 ruling, overturned a 2015 decision by the San Francisco- based 9th U.S. Circuit Court of Appeals that allowed console owners to appeal the dismissal of their class action lawsuit by a federal judge in Seattle in 2012.

Typically parties cannot appeal a class certification ruling until the entire case has reached a conclusion. But the 9th Circuit allowed the console owners to voluntarily dismiss their lawsuit so they could immediately appeal the denial of a class certification.

Justice Ruth Bader Ginsburg, writing on behalf of the court, said such a move was not permitted because a voluntary dismissal of a lawsuit is not a final decision and thus cannot be appealed.

The Xbox console owners filed a proposed class action against Microsoft in federal court in 2011, saying the design of the console was defective and that its optical disc drive could not withstand even small vibrations.
