GAO Updates Bid Protest Protective Order & Guide to GAO Protective Orders

GAO has updated its Protective Order issued in connection with bid protests to require admitted parties to notify GAO within 1 business day of the filing of any related protest before the United States Court of Federal Claims. This change will be effective for Protective Orders issued on or after June 1, 2019. Additionally, GAO's Guide to GAO Protective Orders will be updated to reflect this change, as well as other changes to the Protective Order that were implemented in 2018 as part of GAO's roll-out of the Electronic Protest Docketing System (EPDS).
