The GAO sustained 22.56% of protests decided on the merits in Fiscal Year 2016–nearly double the 12% sustain rate reported in FY 2015.
According to the GAO’s FY 2016 Bid Protest Annual Report, the GAO sustained 139 of the 616 protests decided on the merits (that is, cases where GAO actually reached a “sustain” or “deny” decision). The overall effectiveness rate for protesters–a combination of “sustain” decisions, plus the many cases in which agencies took corrective action in response to protests–was 46%, a slight increase over the prior fiscal year.
