Whether Maryland recognizes detrimental reliance as a basis for enforcing a subcontractor's bid in the construction-bidding setting.
Holding
Yes. A general contractor may invoke detrimental reliance to seek enforcement of a subcontractor's bid, but only upon proof of Maryland's four-part detrimental-reliance test.
Reasoning
The Court rejected the view that detrimental reliance is confined to charitable pledges or other narrow factual settings. Construction bidding presents a recurring fairness problem: a general contractor uses subcontractor bids to formulate a prime bid that may become binding, while a subcontractor under traditional offer-and-acceptance principles may withdraw before acceptance. The Court concluded that the benefits of allowing detrimental reliance in this setting outweigh its risks.
The Court adopted Restatement (Second) of Contracts § 90(1), recasting it as a four-part Maryland test. The general contractor must prove: a clear and definite promise; the promisor's reasonable expectation that the promise will induce action or forbearance; actual and reasonable reliance by the promisee; and a detriment that can be avoided only by enforcing the promise. The Court disapproved prior suggestions that detrimental reliance requires proof of fraud.
The doctrine does not automatically make every sub-bid irrevocable. In construction cases, the general must show that the sub-bid was sufficiently definite, that the subcontractor reasonably expected reliance, and that the general actually and reasonably relied. Whether justice requires enforcement is an equitable question for the trial court, and the general contractor must come with clean hands.
