The Government Accountability Office has been publishing its annual bid protest statistics report to Congress since fiscal year 1995. That year GAO received 2,334 new protests and closed 2,528. For FY 2015, GAO reports that it received 2,496 new protests and closed 2,647.
Given the changes in contract law and the significant increase in expenditures on federal contracts over the last 20 years, these figures are remarkably consistent.
For Fiscal Year 2015, GAO reports that protesters obtained some form of relief in 45 percent of cases closed, either as the result of an agency’s voluntary corrective action or a decision sustaining some or all of the protest grounds. This “effectiveness rate” is marginally higher than it has been in the previous several years, when it hovered between 42 percent and 43 percent.
Winning bases for bid protests
One interesting piece of data added to GAO’s annual report in the last couple of years is the summary of the “most prevalent grounds for sustaining protests.” This new data element is the result of a requirement in a 2013 amendment to the Competition in Contracting Act. See 31 U.S.C. § 3554(e)(2).
In FY 2015, GAO identified five grounds of protest as the most prevalent. Even though it is drawn from only a small subset of protests that are actually resolved on the merits, GAO’s list of reasons for sustaining protests provides a roadmap for future protesters. Here is GAO’s list, along with a brief summary of the decision that GAO cites to illustrate it.
