D.C. Circuit Creates Split over the Reach of the First-to-File Bar
Client Alert | 1 min read | 04.18.14
In U.S. ex rel. Shea v. Verizon Co., the D.C. Circuit held that (1) two complaints may be "related" even if they involve different agencies or contracts, (2) the bar applies even when the same relator filed the earlier action, and (3) it continues to operate even after the earlier-filed action is resolved. The third holding (which drew a dissent) conflicts with dicta from two other circuits and the Fourth Circuit's 2013 opinion in U.S. ex rel. Carter v. Halliburton Co., petition for cert. filed (discussed here), holding that the first-to-file bar only applies while the earlier action is still pending.

It is well established that “[c]ompetitive prejudice is an essential element of every viable protest.” Yet, for decades, the U.S. Government Accountability Office (GAO) has tempered this requirement with two critical corollaries: protesters need only demonstrate a “reasonable possibility” that they were prejudiced by an agency’s actions, and GAO “will resolve doubts regarding prejudice in favor of the protester.” These principles have been consistent features of GAO’s bid protest jurisprudence for more than 30 years. See, e.g., United Int’l Eng'g, Inc., B-245448, Jan. 29, 1992, 71 CPD ¶ 177.
