Twitter Inc. and Yahoo! Inc. won’t get a chance to respond to efforts by the U.S. Department of Justice to bar the companies from sharing information about grand jury subpoenas, at least for now.

The Justice Department is appealing a federal magistrate judge’s orders that gave Twitter and Yahoo the opportunity to respond to the government’s application to restrict disclosure about grand jury subpoenas. The government is also challenging the judge’s order requiring prosecutors file a public copy of its nondisclosure applications.
