Hawkins v. McGee: Expectation Damages and the Hairy Hand Case

Hawkins v. McGee is a 1929 New Hampshire Supreme Court decision, often called the “hairy hand case,” that established expectation damages as the standard remedy for breach of contract. The court held that when a doctor guaranteed a patient “a perfect hand, one hundred per cent good” and delivered a worse one, the patient was entitled to the difference in value between the hand he was promised and the hand he actually received.¹ Nearly a century later, that formula still governs how American courts calculate damages when someone breaks a promise.

The Facts of the Case

George Hawkins was a young man in New Hampshire whose right palm had been badly scarred by an electrical burn in childhood. Dr. Edward McGee, a local physician, approached Hawkins and his father and proposed a skin grafting operation to repair the hand. McGee did not merely offer to try. He guaranteed the outcome, promising Hawkins “a perfect hand, one hundred per cent good.”¹ On the strength of that guarantee, Hawkins agreed.

The surgery grafted skin from Hawkins’s chest onto his palm. It went badly. The graft did not repair the scarring, and the transplanted chest skin began growing thick, dark hair on his palm. Hawkins was left in noticeably worse shape than before the operation. His family sued McGee, not for performing the surgery negligently, but for breaking his promise to deliver a perfect hand.

Was McGee’s Guarantee a Contract?

The first question was whether the guarantee counted as an enforceable promise at all. Doctors routinely reassure patients, and courts have long treated general encouragement as professional opinion rather than binding commitment. A statement that a patient will “feel much better” or should expect “a full recovery” does not create a contract.

McGee’s words were different. He did not predict a likely outcome or express hope; he guaranteed a specific result. The jury found that this specificity crossed the line from opinion into warranty and that McGee had made a special contract with Hawkins that he then failed to perform.¹ The test that emerged is whether the statement is specific enough that a reasonable person would treat it as a factual commitment. A promise of a “one hundred per cent good” hand cleared that bar.

The Damages Ruling

Once the guarantee was treated as a contract, the court turned to what Hawkins should recover. The trial judge had instructed the jury to consider the pain and suffering Hawkins endured from the failed surgery. The New Hampshire Supreme Court held that was the wrong measure.

The reasoning was direct. Any surgery involves pain and recovery, and Hawkins knew that going in. He would have experienced pain and suffering even if the operation had succeeded exactly as promised. Those costs were not caused by the broken promise; they were part of the deal itself. The proper focus in a contract case is not what the injured party went through, but what they lost because the promise was not kept.

The correct measure, the court held, was the difference between the value of the perfect hand Hawkins was promised and the value of the damaged hand he actually received. That formula is now known as expectation damages, and its purpose is to put the injured party in the position they would have occupied if the contract had been fully performed.²

The starting point is worth noting. The court did not measure damages from the original scarred hand Hawkins walked in with. He already had that. What he lost was the gap between the perfect hand he was promised and the worse hand he ended up with. That distinction is what makes this an expectation case rather than a claim to be restored to his original condition.

Expectation, Reliance, and Restitution

Hawkins v. McGee is usually taught alongside the two other measures a court can use when a contract is broken, because the comparison shows what expectation damages do and do not cover. The Restatement (Second) of Contracts identifies three distinct interests a court can protect.³

The expectation interest puts you where you would have been if the contract had been performed. You get the full benefit of the bargain. This is what Hawkins was awarded.
The reliance interest puts you where you would have been if the contract had never been made. You recover costs incurred in reliance on the promise, but not the benefit the promise itself would have delivered.
The restitution interest requires the breaching party to return any benefit you conferred. The focus is on preventing unjust enrichment, not on making you whole.

For Hawkins, a reliance measure would have covered his surgical costs and compensated him for ending up worse off than before, but it would not have included the value of the perfect hand. Restitution would have returned whatever fees he paid McGee and nothing more. Expectation was the most generous because it treated the perfect hand as something Hawkins was legally entitled to receive.

The Limit in Medical Cases: Sullivan v. O’Connor

Hawkins established expectation damages as the default remedy for breach of contract, but a later decision pushed back on applying that default rigidly to medical guarantees. In Sullivan v. O’Connor (1973), a Massachusetts court faced a similar scenario: a plastic surgeon had promised a patient a specific cosmetic result and failed to deliver.⁴

The Sullivan court acknowledged the Hawkins framework but concluded that the full expectation measure could be excessive in medical cases, particularly where the doctor was not negligent in performing the procedure but simply failed to achieve a guaranteed outcome. It favored a reliance measure instead, compensating the patient for expenditures made and the worsened condition suffered because of reliance on the promise, without awarding the full value of the promised result.⁴

Sullivan did not overrule Hawkins. Both agree that a specific guarantee of a medical outcome can create an enforceable contract. They differ on the remedy. Hawkins stands for the principle that expectation damages are the default in contract law generally. Sullivan represents a practical adjustment for medical cases, and many jurisdictions have followed its lead, making reliance damages the more common outcome in medical warranty claims even while Hawkins remains the textbook illustration of the expectation principle.

What Happened to Hawkins and McGee

The New Hampshire Supreme Court did not fix a dollar amount. It reversed the trial court’s damages instruction and sent the case back. Rather than retry it, the parties settled for $1,400.

An ironic postscript followed. McGee submitted the settlement to his malpractice insurer, which refused to pay on the ground that the policy covered negligence in medical treatment, not breach of a voluntary guarantee. The First Circuit agreed, holding that McGee’s liability arose from his “special contract to give his patient a perfect hand” rather than from any error in medical judgment.¹ The line between contract liability and malpractice liability left McGee personally responsible for the settlement.

Why the Case Still Matters

Hawkins v. McGee survives in first-year contracts courses because it isolates the core logic of contract damages in a form that is almost impossible to confuse. A man was promised something specific. He received something worse. The remedy is the gap between the two. The same logic applies whenever a deal is broken, whether in a business negotiation, a real estate transaction, or a warranty on consumer goods, and the Restatement (Second) of Contracts codifies it as the injured party’s interest in “having the benefit of his bargain by being put in as good a position as he would have been in had the contract been performed.”³
