U.S. District Judge Mary Cooper agreed Thursday, and scheduled an Aug. 14 hearing on why the order should not be extended.
The seven troopers were suspended after a college student claimed she had been sexually assaulted in a trooper's Ewing Township home in December after a night out at a Trenton nightclub.
Prosecutors announced earlier this month that the troopers would not be charged, but the troopers still face an internal investigation.
