Sheridan Corporation won a federal construction contract for a KC-135 hangar in Maine. After a losing bidder protested, the agency decided to re-solicit revised proposals from the top three bidders instead of defending its original award. Sheridan sued, and the court ruled the agency's decision was illegal because there were no defects in the original bids and no changes to the project requirements. The court enforced Sheridan's contract, protecting it from a do-over competition that had no legitimate basis.
If you win a federal bid, an agency cannot force a re-competition just because someone protests—only if there are actual errors or requirement changes in the original solicitation.
