Restoration of Equipment After Failed Deal
Umeko Uchida delivered specialized machinery to Urban Logistics under a preliminary agreement that later collapsed. Urban Logistics retained and used the equipment for six months. A court orders return of the machinery itself to eliminate the benefit Urban Logistics obtained without payment.
Indemnity Between Joint Tortfeasors
Uriel Urban paid a full judgment to an injured plaintiff after both he and Uma Upadhyay were found liable for the same accident. Uma Upadhyay received the discharge of her share without contributing. Uriel Urban recovers indemnity from Uma Upadhyay to prevent her retention of that benefit.
Survivorship Title After Divorce Filing
Uriah Urban held a house in tenancy by the entirety with his spouse. He executed a will attempting to leave the house to a third party while divorce proceedings were pending. Upon his death the surviving spouse takes title by operation of law. Equity refuses a constructive trust because no unjust enrichment occurred.
Monetary Award for Services Rendered
Uma Underwood performed extensive network repairs for Upland Industries after the company’s tower failed. No contract formed, yet the company gained reliable service and avoided customer losses. The court awards a sum measured by the reasonable value of the work to prevent the company’s retention of that benefit.
Promise After Gratuitous Benefit
Urban Utley repaired a neighbor’s equipment without any expectation of payment. The neighbor later signed a writing promising substantial compensation. Because the initial work was conferred as a gift, the neighbor was not unjustly enriched and the promise is not binding.
Broadcast of Entire Performance
Ulysses Maritime staged a live human-cannonball act at a fair. A television station broadcast the entire performance without consent. The performer recovers the value of the exclusive publicity right because the station obtained that benefit without payment.
Zacchini v. Scripps-Howard Broadcasting Co.433 U.S. 562 (1977)
Hugo Zacchini performs a "human cannonball" act in which he is shot from a cannon into a net some 200 feet away, with each performance occupying some 15 seconds. In August and September 1972, Zacchini was engaged to perform his act on a regular basis at the Geauga County Fair in Burton, Ohio. He performed in a fenced area, surrounded by grandstands, at the fair grounds, and members of the public attending the fair were not charged a separate admission fee to observe his act.
On August 30, a freelance reporter for Scripps-Howard Broadcasting Co., the operator of a television broadcasting station, attended the fair carrying a small movie camera. Zacchini noticed the reporter and asked him not to film the performance, and the reporter did not do so on that day. On the instructions of the producer of the station's daily newscast, the reporter returned the following day and videotaped the entire act. This film clip, approximately 15 seconds in length, was shown on the 11 o'clock news program that night, together with favorable commentary.
Zacchini then brought this action for damages against Scripps-Howard Broadcasting Co. He alleged that the station showed and commercialized the film of his act without his consent. Such conduct was an unlawful appropriation of his professional property. The trial court granted summary judgment for the broadcaster. The Court of Appeals of Ohio reversed. The Supreme Court of Ohio gave judgment for the broadcaster.
The United States Supreme Court granted certiorari.

Students Frequently Ask...
What must a plaintiff prove to recover under unjust enrichment?
The plaintiff must show that the defendant received a benefit, that retention of the benefit would be unjust, and that the circumstances call for restitution rather than a gift or other justification. Courts measure recovery by the value of the benefit received, not necessarily by the plaintiff’s loss.
Does unjust enrichment require a promise or agreement between the parties?
No. Liability arises from the receipt of a benefit whose retention without payment would result in unjust enrichment even when no promise was made. The duty is imposed by law to prevent inequitable gain.
Supporting sources
When is restitution measured by restoration of a specific thing rather than money?
Restitution takes the form of returning the specific thing when that remedy is available and would prevent unjust enrichment, as when identifiable property remains in the defendant’s possession. Monetary awards are used when specific restoration is impractical.
Supporting sources
How does unjust enrichment interact with indemnity among joint tortfeasors?
When one tortfeasor discharges the common liability, indemnity is available if the other would be unjustly enriched by the discharge. The paying party recovers from the non-paying party to the extent the latter’s share was satisfied without contribution.
Supporting sources
Does a gratuitous benefit support an unjust-enrichment claim?
A benefit conferred as a gift or without expectation of compensation does not create unjust enrichment. The recipient has no duty to pay because the transfer was not unjust.
