Relying upon the cryptic answers provided by a Magic 8-Ball when deciding to file a protest at the United States Court of Federal Claims (COFC) may sound farcical, but a recent decision by a split panel of the United States Court of Appeals for the Federal Circuit may render this method commonplace. In Inserso Corporation v. United States, the Federal Circuit held that the Blue & Gold waiver rule regarding the timeliness of protests against patent solicitation errors barred Inserso’s opportunity to protest the Defense Information Systems Agency’s (DISA’s) allegedly improper disclosure of total evaluated pricing and previously unreleased evaluation methodology during debriefings with certain offerors. In what can only be described as requiring an offeror to possess preternatural foresight of all potential agency errors in a procurement, the Federal Circuit reasoned that Inserso should have known the type of information it challenged was likely to be disclosed in the debriefings. In effect, the majority’s decision unmoors the venerable Blue & Gold waiver rule from its narrow application by requiring – remarkably – that contractors protest non-patent, non-solicitation issues before the deadline for receipt of proposals. Yet the majority’s opinion isn’t the only feature of this decision that should raise contractors’ eyebrows. As noted below, the full-throated dissent questions, inter alia, the continuing validity of Blue & Gold.
