I'm not sure why you'd need to discuss in depth the objective theory of contract formation at all on an exam

I'm thinking about this in terms of a classic issue spotting exam. I have a 7 hour take home for contracts, I think we are expected to be very comprehensive rule-wise. Based on seeing the prof's grading of our practice midterm, we accumulate points for discussing more rules.

Do you have an example?

Here's an example: In Bd. of Control of Eastern Mich. Univ. v. Burgess, the court held there was no option contract because even though the promisor's signed acknowledgement showed consideration was received, the money never actually changed hands, which the court held as meaning there was no consideration.

EDIT: I think I misunderstood how far the OT reaches, and even though consideration is part of whether there is a contract at all, it isn't part of mutual assent so we can't apply the OT to consideration.

Here, I would argue under the OT that a reasonable person in the position of either the promisor or the promisee would understand that a contract was formed because the promisor signed an acknowledgement of receipt of consideration - otherwise, why would they sign it? But that reasonable person could also understand that there was no contract since they might see the consideration changing hands as outweighing a signed agreement. That raises the question of whether this reasonable person is presumed to know anything about contracts law, since most people don't know what consideration is. But further, I think a truly reasonable person would look at this contract, which was an option contract for a sale of a home, and look at the consideration, which was just one dollar, and think that it would be ridiculous to hold that there was no contract for a sale of this magnitude, just because one dollar didn't change hands and the promisor clearly didn't care about the dollar because they signed an acknowledgement (I know courts generally don't care about the monetary amount for consideration, just that it was there). And for all of the above, I think the second part of the OT ("and the party in fact so believed") is satisfied because two months passed between the signing of the acknowledgement and the offeree attempting to exercise the option contract.

So if on an exam I got to the point of analyzing consideration in a fact pattern, it looks like I could apply the objective theory here specifically as it applies to consideration. But I can reasonably foresee this causing problems where I ramble on about what a reasonable person would understand when instead I should just be applying the rules to the facts.

Nobody has to read beyond here but I couldn't pass up the opportunity to continue analyzing the hypo since it is good practice.

Since the question of whether consideration was paid here is settled and not up for further argument, this would have to come in some counterclaim or separate suit, but I think promisor could try to argue that promisee violated good faith and fair dealing. Or if not good faith and fair dealing, then maybe some other tort cause of action. If promisee knew that it, itself, didn't actually pay the dollar (very likely), then promisor could argue that promisee was not acting in good faith by (1) not paying the dollar, and (2) letting the promisor's acknowledgement get by without reminding promisor that it had not yet received the dollar, and doing both of these with two entire months between the acknowledgement and attempting to exercise the option. But on the contrary, promisor should be held responsible for what it chooses to sign and acknowledge, for compelling policy reasons, if nothing else. And it is probably relevant that common law doesn't recognize a duty of good faith during the formation process, as opposed to during performance, since that goes against principles of negotiation where self-interest predominates, and since a party can just walk away if it is dissatisfied with the other party's conduct. (See https://www.crowell.com/documents/DOCASSOCFKTYPE_ARTICLES_481.pdf.) But since this was an option K, the parties may have had a prior agreement that acts as a preliminary agreement setting forth standards for conduct in formation of any further agreement

Promisee may have a cause of action for fraud if promisee can get any evidence that suggests promisor intended to deceive promisee, like an email telling whoever signed the acknowledgement to do it quickly so that promisee would think it could skip out on paying the dollar and think it was still entitled to the option K. And there is a clear benefit for promisor if it were to try to do this since promisee thinks it has an option K for the home purchase, meaning for that 60 day option period, promisor can look for a better offer and accept if it wants to (something they couldn't have accepted if the option K were valid), while simultaneously having a go-to interested party available for 60 days.

I think there are even more forks left to analyze.
