in which ''quantum valebant'' was allowed is ''In re Monitor Prods. Co.''.Decisions of the U.S. Comptroller General (July 27, 1976), No. B-182437 In that case, the United States Navy had entered into a contract to buy 160 electronic oscillator units at a specified price. The Navy later decided that it wanted 40 more units. Monitor, the subcontractor, told the Navy's project engineer that it needed substantial price increase for the additional 40 units as well as reimbursement for cost overruns which it was incurring in producing the initial 160 units; otherwise it would have to cease production. No additional formal contract was signed, but the project went ahead and Monitor provided the 200 units. The Navy declined to pay any additional amount, although Monitor insisted that it was induced to incur the additional costs by a representative of the Navy (the project engineer), who appeared to have the authority to commit the Government. The Comptroller General of the United States held that

the courts and our Office have recognized that in appropriate circumstances payment may be made for services rendered on a ''quantum meruit'' basis (the reasonable value of work or labor), or for goods furnished on a ''quantum valebat'' basis (the reasonable value of goods sold and delivered).

According to the ruling, the Navy ratified an agreement for the extra units and cost overrun. Therefore, "Monitor's claim may be paid to the extent that the value of the items furnished exceeds any compensation which Monitor may have received from" the prime contractor for the work.
