Questions & Answers

Q: What is the mirror image rule?

The mirror image rule states that the acceptance of an offer must precisely mirror the terms of the offer without any variations or additions. Any changes to the terms constitute a counter offer and terminate the original offer.

Q: What happens if an offeree varies the terms of an offer in their acceptance?

If an offeree introduces new or different terms in their acceptance, it is considered a counter offer. The original offer is terminated, and further negotiation is required to reach a mutual agreement.

Q: Can a non-material variation in terms, such as an air freshener, affect the validity of an acceptance?

Yes, even a non-material variation can be fatal to the acceptance under the mirror image rule. The assumption is that any new or different terms introduced in the acceptance require further negotiation.

Q: Can the mirror image rule be bypassed or altered?

Yes, both the offeror and offeree can contract around the mirror image rule. Through explicit agreements or specifying that a counter offer does not terminate the original offer, the parties can modify the default rule.

Summary & Key Takeaways

• In the case Minneapolis and St Louis Railway Company v. Columbus Rolling Mill Company, the court held that no contract was formed when the plaintiff attempted to accept the defendant's offer while modifying the terms.

• The mirror image rule requires total congruence between the offer and acceptance, and any variation in terms is treated as a counter offer, ending the negotiation.

• The mirror image rule makes it more difficult to create contracts, but it provides clarity and limits the potential for confusion or manipulation.
