# §21.9. Time for decision by GAO.

- (a) GAO shall issue a decision on a protest within 100 days after it is filed. GAO will attempt to resolve a request for recommendation for reimbursement of protest costs under [§ 21.8(e)](/cfr/4/21.8.md?p=e), a request for recommendation on the amount of protest costs under [§ 21.8(f)](/cfr/4/21.8.md?p=f), or a request for reconsideration under [§ 21.14](/cfr/4/21.14.md) within 100 days after the request is filed.
- (b) In protests where GAO uses the express option procedures in [§ 21.10](/cfr/4/21.10.md), GAO shall issue a decision on a protest within 65 days after it is filed.
- (c) GAO, to the maximum extent practicable, shall resolve a timely supplemental protest adding one or more new grounds to an existing protest, or a timely amended protest, within the time limit established in [paragraph (a)](#a) of this section for decision on the initial protest. If a supplemental or an amended protest cannot be resolved within that time limit, GAO may resolve the supplemental or amended protest using the express option procedures in [§ 21.10](/cfr/4/21.10.md).
