Contracts · Mutual assent: offer and acceptance

Revocation of offers

Place the offeree’s knowledge beside the attempted acceptance before deciding whether withdrawal worked. An offeror’s private change of mind does not give the recipient notice, while a dependable report of an inconsistent sale can matter without coming from an authorized agent. For a short timeline exercise, assume an unprotected, revocable offer: the buyer receives a clear withdrawal at noon and tries to accept that afternoon. The later response cannot revive the proposal. Now add a fact supporting protection against withdrawal and analyze that protection separately. A decision deadline alone does not supply it. A paid option, a merchant’s signed goods assurance and justified reliance on a construction bid each call for their own requirements. Even reliance protection has limits: it should not silently become permission to delay while shopping for a better price. Keep notice, effective acceptance and the basis for any hold-open obligation as three distinct findings.

The rule

BLACK-LETTER RULE

A revocable offer can be withdrawn before acceptance through received withdrawal or reliable knowledge of an inconsistent sale. A deadline alone does not establish irrevocability. Supported options, merchant signed assurances and jurisdiction-specific reliance rules require separate analysis.

Elements

  1. An offer still capable of acceptance.
  2. Withdrawal or reliable knowledge before the alleged acceptance.
  3. Evaluation of any independent protection against revocation.

Exceptions and limits

  • Section 2-205 has a three-month limit on its without-consideration protection and a separate-signature rule for an offeree form.
  • Drennan protects justified reliance for a prompt acceptance opportunity, not bid shopping.

When the issue arises

An offeree attempts acceptance after hearing of a sale, receiving a withdrawal, or sending different terms. Separate the offer's continued existence from any claimed right to keep it open.

Knowledge of the sale matters to the sequence

Dickinson had knowledge of the inconsistent transaction before his attempted acceptance. The unpaid hold-open assurance did not prevent withdrawal on those facts. The decision does not treat an undisclosed change of mind as communicated revocation.

Normile adds a different first step: the proposed change in terms was a counteroffer, not acceptance or a purchased option. The buyer also learned of the completed sale before later attempting to accept the original terms.

A protected offer requires its own foundation

A supported option and a model-UCC firm offer have different requirements. Section 2-205 concerns a merchant's signed assurance for goods, with a stated or reasonable protection period capped at three months without consideration under that section.

If the assurance is on the offeree's form, the offeror must separately sign it. Do not turn every printed deadline or casual promise into an irrevocable statutory offer.

Reliance does not equal acceptance

After learning that Star would not honor its quote, Drennan promptly insisted that Star had the subcontract. His later search for another paver addressed the cost of replacing that refused performance. Distinguish that sequence from postponing commitment while trying to improve the original bargain.

James Baird reached a different reliance result on its offer and chronology. Identify the governing approach and any knowledge of a mistake, rather than claiming a nationwide majority or assuming award of the general contract itself accepts every sub-bid.

A simple fact pattern

Facts. An owner offers a motorcycle to a buyer without any supported hold-open promise. Before the buyer responds, the owner telephones and clearly withdraws. The buyer hears the withdrawal but accepts the next day.

Analysis. The received withdrawal precedes acceptance, and the hypothetical provides no protection against revocation. A reply after that sequence does not create the original proposed sale.

A harder fact pattern

Facts. A contractor reasonably uses a subcontractor's bid in a successful general bid. The subcontractor seeks to withdraw; the contractor then waits while seeking a lower price before attempting to accept the original bid. Apply Drennan.

Analysis. The original justified reliance supports examining protection against withdrawal, but the contractor's later price shopping undermines the prompt opportunity Drennan recognized. Do not extend that protection into an unrestricted option or confuse the general-bid submission with acceptance of the subcontract.

Common exam mistakes

  • Treating an undisclosed sale as notice to the offeree.
  • Making a friend's reliable firsthand report legally irrelevant for lack of agency.
  • Assuming every deadline supplies a supported option.
  • Using reliance to justify unlimited delay or bid shopping.

Practice questions

Question 1

A seller makes a revocable land-sale offer with an unpaid decision deadline. Before the buyer accepts, a reliable witness tells the buyer that the seller has completed an inconsistent sale. Under Dickinson's reasoning, what follows if the buyer nevertheless attempts acceptance within the original deadline?

Answer and explanations

Correct answer: B.

Authority: Dickinson: knowledge before attempted acceptance

  • A. Wrong. A gratuitous deadline alone did not establish the supported option claimed in Dickinson.
  • B. Correct. The buyer knows of the completed inconsistent transaction before attempting acceptance. The reliable information matters even without personal withdrawal by the seller.
  • C. Wrong. Dickinson did not require the offeror personally to deliver the information.
  • D. Wrong. The attempted acceptance follows notice ending the power to accept; a deadline does not cure that sequence.

Quick answers

Must the seller personally announce withdrawal?

Not on the facts of Dickinson and Normile. Knowledge of the inconsistent completed sale before acceptance mattered, even though the information came through another person.

Does a three-month limit apply to every option?

No. That limit concerns irrevocability without consideration under UCC 2-205. Do not transpose it to every independently supported option.

Does Drennan protect a contractor who shops the bid?

It does not supply an unrestricted right to delay or seek a better deal. Its justified reliance analysis preserves a prompt opportunity to accept.
