If circumstances arise that make performance extremely difficult or costly, the contract may be discharged
under the doctrine of commercial impracticability. The anticipated performance must become extremely
difficult or costly. Circumstances of which businesspersons at the time of contracting are or should be
aware, however, do not qualify.
CASE SYNOPSIS
Case 17.3: Merry Homes, Inc. v. Chi Hung Luu
Chi Hung Luu leased premises in Houston, Texas, from Merry Homes, Inc. The lease provided that Luu could use
the promises only to operate a nightclub or bar. After he signed the lease, Luu applied for a liquor license. The
application was denied under a city ordinance that prohibited the sale of alcoholic beverages where the premises were
located (close to a public school). Luu asked Merry Homes to cancel the lease and refund his $6,000 security deposit,
but the landlord refused. Luu filed a suit in a Texas state court against Merry Homes. The court declared the lease void,
and Merry Homes appealed.

Notes and Questions
Contract liability is strict liability, or, as a Latin maxim expresses it, pacta sunt servanda (contracts are to be kept).
In the early years of the common law, courts made exceptions to this rule, and excused a party from fulfilling
contractual duties, when performance became impossible due to the first three situations outlined in the text. In early
cases, however, a supervening event that made performance more difficult or more costly, or that made the contract
less profitable, or even unprofitable, did not excuse performance. The general rule was that commercial
impracticability was not sufficient to excuse performance because excuse of performance required impossibility. As the
law developed through the centuries, this rule changed. Courts came to release parties from their contractual
obligations when performance was not impossible but was highly impracticable.
Literally, the doctrine of impossibility is intended to excuse the performance of a duty because of impossibility.
Could the lease of an apartment located on the top floor of a three-story building be canceled if the tenant became
permanently disabled and unable to reach the apartment? If the lease were assignable, it probably would not be
cancelable. Could an automobile lease be canceled if the lessee were hospitalized and unable to drive? If the lease
could be sold, it probably would not be cancelable.
Does a power failure constitute the kind of unexpected occurrence that relieves a party of the duty to perform a
contract? In what circumstances might a power failure have no effect on a contract? The answer to the first question is
no. In deciding whether a party should be relieved of the duty to perform a contract, a court determines whether the
existence of a specific thing is necessary for the performance of a duty and whether its loss or deterioration makes
performance impracticable. A power failure is the kind of unexpected occurrence that may relieve a party of the duty
CHAPTER 17: PERFORMANCE & DISCHARGE IN TRADITIONAL & E-CONTRACTS 413
to perform if the availability of electricity is essential for performance. Thus, the answer to the second question would
include circumstances in which electricity is not essentiala sale or lease of land, a delivery of goods, or the
performance of any service for which electricity is not necessary.
ANSWER TO “WHAT IF THE FACTS WERE DIFFERENT?” IN CASE 17.3
Suppose that Luu had decided to use the premises for a restaurant, but the wording of the lease was not changed.
In this situation, if Luu sought to cancel the lease, would Merry Homes succeed in a suit for breach of contract? That
Luu’s intended use of the premises (to operate a restaurant) would now be a legal use would not alter the fact that the
probably not be admissible.
ANSWER TO “THE ETHICAL DIMENSION QUESTION IN CASE 17.3
“Ignorance of the law is no excuse.” How does this case affirm that adage? Merry Homes tried to argue that Luu’s
ignorance of the law did not justify voiding the contract. According to Merry Homes, Luu should have checked, before
signing the lease, on whether the premises could be used for a bar or nightclub. Luu’s failure to do so was no one’s
fault but his own, and thus he should held liable under the contract to Merry Homes for damages. The court, however,
stated that the contract called for an illegal act and was thus void—“whether the parties knew the law or not.”

TEACHING SUGGESTIONS
1. Students find the subject of conditions generally difficult. It may be made easier by emphasizing that there are
clearly implied conditions that exist of necessity in every contract. For example, a contract for the performance of
over their contract obligations.
2. Students often believe that only complete performance is valid. It is important to underscore that the law
recognizes various degrees of performance. Have students explain what is required of a party who wants to render
3. You might tell students that in taking notes, they may find it helpful to use some of the terms, abbreviations, and
symbols that law students, lawyers, an judges use in their note-taking and writing. Some of the abbreviations are those
that appear in case citations—”S.Ct.” for the United States Supreme Court, for example. “J.” can be shorthand for
“judge” and “JJ.” for “judges.” Symbols that are commonly used include “K,” which is used to refer to a contract. To
indicate a reference to a plaintiff, the pi symbol—””—is often used, and a defendant is noted by a triangle—”.”

contractual obligations under the doctrine of impossibility of performance include: (1) one of the essential parties to a personal

the contract); (2) the specific subject matter of a contract is destroyed (a fire that destroys a building discharges a contract for
its sale); (3) a change in law renders performance illegal (lowering the usury rate renders contracts to loan money at higher
rates illegal). Commercial Impracticability. To discharge a contract under the doctrine of impracticability, performance must
ACTIVITY AND RESEARCH ASSIGNMENT
Have students draft a simple contract for a small construction project (remodeling a kitchen, for instance) under which
a homeowner hires an independent contractor to do the work. Consider the points of view of (1) the homeowner, (2) the
contractor, and (3) a subcontractor. What clauses would each party want in his or her contract to assure satisfactory
performance by the others? How specific should the details regarding the work be? To whose advantage is it to be specific?
What recourse would each party have if the others did not perform? Should that be spelled out in the contract?
Provisions commonly included in personal service contracts concern amounts and methods of payment; descriptions of
the work to be done; materials that will be used and who will pay for them; deadlines; what constitutes completion of the work;
what happens if the work or payment is late or incomplete; the status of the party performing the work (independent
contractor); responsibility for any injury; indemnity for injury to others; and how disputes should be resolved.

EXPLANATIONS OF SELECTED FOOTNOTES IN THE TEXT
Footnote 5: Su Yong Kim sold an apartment building in Portland, Oregon, to Chon Sik Park, Bok Soon Park, Johan Cen,
William Itzineag, Johnny Perea, and Patricia Maldonado. Kim promised to repair the building’s plumbing, which violated the
Portland Housing Code, within eight months. Twelve months after date of the contract, Kim cut holes in the walls to expose the
plumbing and, seven weeks later, sent plumbers to the building. The owners ordered the plumbers to leave and stopped making
payments under the contract. Kim filed a suit in an Oregon state court against the buyers, seeking the amount due. The buyers
asserted that Kim’s failure to repair the plumbing was a material breach that excused their performance. The court concluded
that Kim’s breach was not material. The buyers appealed.
Can the buyers keep the apartment building without making further payments under the contract? When a party
materially breaches a contract, a non-breaching party has a choice of remedies. He or she can elect rescission and restitution of
the money paid, or can affirm the contract and seek damages for the breach. If the non-breaching party chooses rescission, his
or her contractual obligations are entirely discharged. If, however, the non-breaching party chooses to affirm the contract and
seek damages, his or her obligations are reinstated once the breaching party performs or the failure to perform is otherwise
excused. How do these principles apply in this case? Here, the buyers sought to affirm their contract and obtain damages, and
the lower court awarded damages to them. The appellate court stated, “When plaintiff’s material breach is cured by the
satisfaction of the judgment for damages awarded to defendants, defendants’ obligation to make the payments due under the
contract will resume.
This case might serve to initiate a discussion as to what students expect from the law. Do they believe that it should
guarantee perfection by all parties? Total absolute performance? How far might a contracting “push the envelope” before
being in breach of contract?.
Footnote 21: Cape-France Enterprises owns real property in Bozeman, Montana. Lola Peed and Marthe Moore
In Cape-France Enterprises v. Estate of Peed, the Montana Supreme Court affirmed. Rescission was appropriate
because Cape-France would otherwise be forced to expose itself to substantial and unbargained-for economic risks, to expose
CHAPTER 17: PERFORMANCE & DISCHARGE IN TRADITIONAL & E-CONTRACTS 419
the public to potential health risks, and to expose the environment to possible degradation. “[A]n act is impracticable when it
can only be done at an excessive, unreasonable and unbargained-for cost.” This doctrine applies where, as here, “the public
policy underlying the strict enforcement of contracts is outweighed by the senselessness of requiring performance.”
Literally, the doctrine of impossibility is intended to excuse the performance of a duty because of impossibility. Could
the lease of an apartment located on the top floor of a three-story building be canceled if the tenant became permanently
disabled and unable to reach the apartment? If the lease were assignable, it probably would not be cancelable. Could an
automobile lease be canceled if the lessee were hospitalized and unable to drive? If the lease could be sold, it probably would
not be cancelable.
Why is the risk to Cape-France of the cost of a clean up not interpreted as the same as a risk in the rise or fall in the
price of the land? Here, in the eyes of the court, the rise in cost is due to an unforeseen contingency, which alters the essential
nature of performance. A rise or fall in a market price is the type of risk for which contracts are made, however.

 PERFORMANCE AND DISCHARGE
IN TRADITIONAL AND E-CONTRACTS 
Val’s Foods signs a contract to buy 1,500 pounds of basil from Sun Farms, a small organic herb grower, as long as
an independent organization inspects and certifies that the crop contains no pesticide or herbicide residue. Val’s has a
number of contracts with different restaurant chains to supply pesto and intends to use Sun Farms’ basil in its pesto to
fulfill these contracts. While Sun Farms is preparing to harvest the basil, an unexpected hailstorm destroys half the
crop. Sun Farms attempts to purchase additional basil from other farms, but it is late in the season and the price is
twice the normal market price. Sun Farms is too small to absorb this cost and immediately notifies Val’s that it will not
fulfill the contract. Ask your students to answer the following questions, using the information presented in the
chapter.
1. Suppose that the basil does not pass the chemical-residue inspection. Which concept discussed in the chapter
might allow Val’s to refuse to perform the contract in this situation? The appropriate concept would be discharge by
failure of a condition. Under the contract, Val’s does not have to perform (pay) unless the basil meets the stated
2. Under which legal theory or theories might Sun Farms claim that its obligation under the contract has been
discharged by operation of law? Discuss fully. The theory of commercial impracticability can excuse parties from their
price meets this requirement: doing so would bankrupt Sun Farms.
3. Suppose that Sun Farms contacts every basil grower in the country and buys the last remaining chemical-free basil
anywhere. Nevertheless, Sun Farms is only able to ship 1,475 pounds to Val’s. Would this fulfill Sun Farms’ obligations
to Val’s? Why or why not? Substantial performance is good faith performance that does not vary greatly from the
4. Now suppose that Sun Farms sells its operations to Happy Valley Farms. As a part of the sale, all three parties
agree that Happy Valley will provide the basil as stated under the original contract. What is this type of agreement
called? This is a novationan agreement between the contracting parties to substitute a third party for one of the
original parties. Under a novation, the new contract extinguishes the old contract and discharges the obligations of the
prior party to the contract.

The doctrine of commercial impracticability should be abolished. Contracts are not made to be broken, even if
that is a popular saying. Contracts are made to be respected. Those who seek to avoid their contractual obligations
by using the excuse of commercial impracticability, if successful, reduce the certain of contractual obligations and end
