R2d § 50: Acceptance of Offer Defined; Acceptance by Performance; Acceptance by Promise

(1) Acceptance of an offer is a manifestation of assent to the terms thereof made by the offeree in a manner invited or required by the offer.

(2) Acceptance by performance requires that at least part of what the offer requests be performed or tendered and includes acceptance by a performance which operates as a return promise.

(3) Acceptance by a promise requires that the offeree complete every act essential to the making of the promise.

What is an acceptance?

R2d § 50(1): acceptance is a manifestation of assent to the terms of the offer, made by the offeree in a manner invited or required by the offer.

Two requirements:

Aaron offers to sell his Honda Civic for $10,000. Benjamin replies "I accept." — contract. Benjamin replies "I accept, but I'll pay next month." — acceptance, or counter-offer?

R2d § 58: Necessity of Acceptance Complying with Terms of Offer

An acceptance must comply with the requirements of the offer as to the promise to be made or the performance to be rendered.

The mirror-image rule

At common law, the offeror is master of the offer: the acceptance must mirror the offer exactly. Any deviation is not an acceptance — it is a counter-offer that terminates the original offer.

Modern courts soften this: a reply that merely requests a change (not conditioned on it) can still be an acceptance.

R2d § 59: Purported Acceptance Which Adds Qualifications

R2d § 59. A reply to an offer which purports to accept it but is conditional on the offeror's assent to terms additional to or different from those offered is not an acceptance but is a counter-offer.

R2d § 61: Acceptance Which Requests Change of Terms

R2d § 61. An acceptance which requests a change or addition to the terms of the offer is not thereby invalidated unless the acceptance is made to depend on an assent to the changed or added terms.

UCC § 2-207 decision tree

UCC 2-207 battle-of-the-forms decision tree tracing the path from offer receipt through the mirror-image test, the conditional-acceptance exception under 2-207 sec. 1, the between-merchants gate, and the three conditions under 2-207 sec. 2 determining when an additional term is excluded.
Today's cases walk the full tree: formation at 2-207 sec. 1, then term inclusion or exclusion at 2-207 sec. 2.

Flender Corp. v. Tippins International, Inc.

830 A.2d 1279 (Pa. Super. Ct. 2003)
Pennsylvania Superior Court

Rule. Under UCC § 2-207, when an offer and acceptance contain conflicting terms on the same subject, both conflicting terms drop out and default rules supply the gap. Forum-selection clauses that disagree are knocked out; jurisdiction is governed by background law.

State Department of Transportation v. Providence & Worcester Railroad Co.

674 A.2d 1239 (R.I. 1996)
Supreme Court of Rhode Island

Rule. An acceptance is not rendered counter-offer by terms that are immaterial or that the offer itself permits. Changes that do not alter the substance of the bargain or impose new burdens on the offeror leave acceptance effective.

R2d § 63: Time When Acceptance Takes Effect

Unless the offer provides otherwise,

(a) an acceptance made in a manner and by a medium invited by an offer is operative and completes the manifestation of mutual assent as soon as put out of the offeree's possession, without regard to whether it ever reaches the offeror; but

(b) an acceptance under an option contract is not operative until received by the offeror.

Mailbox rule: acceptance, then rejection

R2d § 63(a): acceptance is effective on dispatch — the moment it leaves the offeree's possession. Revocations and rejections are effective on receipt.

The cross-over (R2d § 40): if the offeree sends a rejection first, then an acceptance, the mailbox rule is suspended — whichever the offeror receives first governs.

And the mailbox rule does not apply to option contracts: there, acceptance is effective only on receipt.

Worked example: Problem 6.2, An Earnest Letter

Erneste Ardente bid $250,000 for the Horans' residential property. After the bid was accepted, Ardente executed the purchase and sale agreement. His attorney returned the signed agreement plus a $20,000 check along with this letter:

"My Clients are concerned that the following items remain with the real estate: a) dining room set and tapestry wall covering in dining room; b) fireplace fixtures throughout; c) the sun parlor furniture. I would appreciate your confirming that these items are part of the transaction, as they would be difficult to replace."

The Horans refused to include those items and did not sign. Ardente sued for specific performance.

Was Ardente's letter a counter-offer or a valid acceptance with a collateral inquiry?

Stretch: Problem 6.3, Conditional Acceptance of a Court Order

Ibrahim lost a federal-court suit attacking a New Jersey child-support order. He then sent a twelve-page letter to various officials titled "Conditional Acceptance for the Value/Agreement/Counter Offer to Acceptance of Offer," stating that he had "received your offer and accept[ed]" it, subject to conditions, primarily that the recipients justify the existence of various government agencies. The letter asserted that any failure would result in default and an obligation to pay $3.5 million.

Did Ibrahim's "Conditional Acceptance" letter constitute a valid acceptance?

Class summary

Rules. R2d §§ 50, 58, 59, 61, 63 (and § 40 cross-over) · UCC § 2-207.

Cases. Flender Corp. v. Tippins International (knockout) · State Department of Transportation v. Providence & Worcester Railroad Co. (immaterial variation).

Open question. The mirror-image rule controls the common-law side; UCC § 2-207 routes sales of goods. Class 10 walks the full § 2-207 tree branch by branch: when do additional terms join the contract, when do conflicting terms knock out, and what gap-fillers does the UCC supply?
