Fact pattern

Lakefront Outfitters emailed Morgan at 9:00 a.m. on Monday: "We will sell 80 camping stoves for $42 each. Let us know by Friday at 5:00 p.m. if you accept." On Tuesday afternoon, Lakefront mailed a signed revocation. Morgan mailed an acceptance on Wednesday morning after reading the original email and then sent a short follow-up email on Thursday that said, "Confirming that I accepted the stove deal." Morgan received the mailed revocation late Friday afternoon. Lakefront now argues that no contract formed because it mailed the revocation before Morgan received it.

Quick answer

A contract formed on Wednesday morning when Morgan dispatched the acceptance, so Lakefront is bound to sell the 80 camping stoves at the stated price. An offer creates the power of acceptance when it justifies the offeree in understanding that assent will conclude the bargain. A revocation is generally effective only when received by the offeree. By contrast, a properly dispatched acceptance sent by an authorized or reasonable medium is effective on dispatch under the mailbox rule unless the offer says otherwise. If the offeree dispatches an acceptance before receiving a revocation, the acceptance controls and the contract forms at dispatch.

IRAC model answer

Issue

Did Morgan form a contract before Lakefront's attempted revocation became effective?

Rule

An offer creates the power of acceptance when it justifies the offeree in understanding that assent will conclude the bargain. A revocation is generally effective only when received by the offeree. By contrast, a properly dispatched acceptance sent by an authorized or reasonable medium is effective on dispatch under the mailbox rule unless the offer says otherwise. If the offeree dispatches an acceptance before receiving a revocation, the acceptance controls and the contract forms at dispatch.

Application

Lakefront's Monday email was a valid offer because it identified the goods, quantity, price, and a firm deadline. Nothing in the email required acceptance by a single exclusive method, so ordinary commercial methods such as mail or email were reasonable. Lakefront's Tuesday revocation did not terminate Morgan's power of acceptance when Lakefront mailed it. Revocation takes effect only when the offeree receives it, and Morgan did not receive the letter until Friday afternoon. Morgan mailed a clear acceptance on Wednesday morning while the offer was still open. That mailing was an authorized and reasonable medium, so the acceptance became effective as soon as Morgan dispatched it. The Thursday email did not change the result; it merely confirmed a contract that had already formed on Wednesday. Because Morgan's acceptance became effective before any revocation was received, Lakefront could not withdraw the offer in time.

Conclusion

A contract formed on Wednesday morning when Morgan dispatched the acceptance, so Lakefront is bound to sell the 80 camping stoves at the stated price.

Numbered reasoning steps

  1. Identify the offer terms and confirm that the email set a clear acceptance deadline.
  2. Ask when the revocation became effective. Mailing alone is not enough.
  3. Check whether the offeree used an authorized or reasonable method of acceptance.
  4. Apply the mailbox rule to determine the moment of contract formation.
  5. Resolve the timing conflict by comparing the dispatch of acceptance with receipt of revocation.

Why wrong answers fail

The revocation became effective when Lakefront mailed it.

That flips the revocation rule. Revocation requires receipt by the offeree, not dispatch by the offeror.

The Thursday email was the first effective acceptance.

The Wednesday mailed acceptance already formed the contract because the offer did not bar acceptance by mail.

The Friday deadline defeats the mailbox rule.

A deadline limits how long the offer stays open, but it does not change the default dispatch rule unless the offer demands receipt by the deadline.

The UCC makes the mailbox rule irrelevant here.

Even if Article 2 supplies background principles because goods are involved, the timing result is the same: acceptance beat receipt of revocation.

Issue-spotting checklist

  • Spot the offer, the deadline, and any limits on the method of acceptance.
  • Separate dispatch rules from receipt rules before comparing timestamps.
  • Do not treat a mailed revocation as effective when sent.
  • Check whether a later communication is a true second acceptance or only a confirmation.
  • State the exact moment of formation because that drives the breach analysis.
