To the maximum extent practicable, the Comptroller General shall provide for the inexpensive and expeditious resolution of protests under this subchapter. Except as provided under paragraph (2) of this subsection, the Comptroller General shall issue a final decision concerning a protest within 100 days after the date the protest is submitted to the Comptroller General.

The Comptroller General shall, by regulation prescribed pursuant to section 3555 of this title, establish an express option for deciding those protests which the Comptroller General determines suitable for resolution within 65 days after the date the protest is submitted.

An amendment to a protest that adds a new ground of protest, if timely made, should be resolved, to the maximum extent practicable, within the time limit established under paragraph (1) of this subsection for final decision of the initial protest. If an amended protest cannot be resolved within such time limit, the Comptroller General may resolve the amended protest through the express option under paragraph (2) of this subsection.

The Comptroller General may dismiss a protest that the Comptroller General determines is frivolous or which, on its face, does not state a valid basis for protest.
