A federal judge has ordered the General Services Administration to re-evaluate bids for its billion-dollar e-travel contract awarded last June.

GSA, which runs the e-travel program for civilian agencies, awarded a $1.4 billion, 15-year contract to Concur Technologies. But work to transition agencies to the Concur e-travel system was delayed by a protest of the contract award by competitor CWT Sato Travel, an existing e-travel vendor to many agencies.
