Story highlights The State Department is expected to release fewer than 1,000 pages of Hillary Clinton's emails recovered from her private server before Election Day, per a federal judge's order Friday

Washington (CNN) A federal judge on Friday ordered the State Department to release some, but not all, of the emails recovered from Hillary Clinton's private server by the FBI ahead of the presidential election in November.

DC District Court Judge James Boasberg said the department must process 1,050 pages of emails between now and November 4, releasing any non-exempt documents aside from those that are determined to be duplicates of those already released.

It is unclear exactly how many pages the State Department will have to release as part of that order, but it is expected to be significantly fewer than 1,000 pages. That's because a "substantial number" of the recovered documents are duplicates or near-duplicates, a Justice Department attorney representing the State Department said in court.

The State Department has appraised approximately 15,000 documents recovered by the FBI, believed to have been sent by or to former Secretary Clinton while she was in office. Of those, over 9,400 have been deemed personal and therefore not subject to release, the attorney said, while approximately 5,600 are believed to be work-related.

Production will begin October 7, with subsequent releases October 21 and November 4 -- four days before the election.
