The court has concurrent jurisdiction involving contracts with the federal government, where a contractor has the option of choosing between filing suit with the court or with the agency Board of Contract Appeals. The general rule is that a contractor may either 1) file suit within 90 days with the agency Board of Contract Appeals or 2) file suit within one year with the court. A contractor, however, must choose which forum in which to file; a contractor cannot file suit with both the agency Board and with the court. (However, in a case where a contractor has filed with the Board, and the Government challenges the timeliness of the filing — the 90-day limit is statutory and cannot be extended — the contractor can file with the court within the one-year period to protect its claims).
