SAN FRANCISCO — The U.S. Court of Appeals for the Ninth Circuit has put the brakes on a class action privacy lawsuit against Facebook Inc. that had been set to go to trial in July.

In an order signed by Ninth Circuit Judges William Fletcher and Consuelo Callahan Tuesday, the court granted an emergency motion for interlocutory review of an April class certification ruling. That ruling certified a class of Illinois Facebook users bringing claims under the state’s Biometric Information Privacy Act (BIPA) over Facebook’s photo scanning technology.
