Wichita ? Attorneys for Facebook and a Kansas man who filed a class-action lawsuit over privacy issues have jointly asked a federal judge to delay proceedings while a panel decides whether to consolidate similar lawsuits elsewhere.

The lawsuit by Leawood resident John Graham is one of more than a dozen filed nationwide alleging Facebook tracked users’ Internet activity without consent while they were logged out of the social networking site.

A document filed Tuesday in Graham’s case asks for a delay while the Panel on Multidistrict Litigation decides on a request by plaintiffs in a California case who want to coordinate or consolidate similar lawsuits. The consolidation request is expected to be heard by the judiciary panel in Miami on Jan. 26.
