COVID-19 Coronavirus: Will Global Pandemic Excuse Contractual Performance?

March 17, 2020

A Review of U.S. Law on Force Majeure, Frustration of Purpose, Impracticability, and Impossibility

The current outbreak of the coronavirus (also known as COVID-19), recognized by the World Health Organization as a global pandemic, has already had a significant effect on certain businesses and appears likely to have an even greater impact, raising widespread concerns about the ability to perform and cost of performing under commercial contracts. Through government-mandated quarantines, travel restrictions, supply shortages, labor shortages, demand reductions and other complications caused by COVID-19, there are many ways in which contractual performance has become and could become even more challenging. Parties to commercial contracts – whether seeking to enforce counterparties’ contractual obligations or seeking to be excused from their own performance – must consider the potential applicability of the following defenses:

  • Force Majeure Contract Clauses; and/or
  • Extra-Contractual Doctrines, such as
    • Impossibility of Performance;
    • Impracticability of Performance; and/or
    • Frustration of Purpose.

In addition, if one of these defenses potentially applies, the party will need to consider the effect of the defense in terms of allocating various costs and expenses between the parties.

Force Majeure Contract Clauses

Force majeure clauses generally provide that upon the occurrence of specified events, and subject to certain conditions, a party to a contract will be relieved to some extent from its duties thereunder. Under U.S. law, enforceability of such clauses is a function primarily of their express language. Courts resolving disputes over force majeure provisions consider the language thereof and apply state law to determine the parties’ intentions.1 Ultimately, the burden of demonstrating entitlement to relief is on the party seeking to have its performance excused.2

In determining whether a force majeure clause applies, the first thing to consider is whether the event at issue is covered by the clause. Typically, covered events include acts of god, war, strikes, and governmental prohibitions, among other things that are out of the parties’ control. Some contracts expressly refer to epidemics and quarantine restrictions. Others also include a catchall provision intended to encompass events that are not expressly identified.

If an event is not specifically listed in the contract, a court is likely to construe the force majeure clause narrowly.3 Some courts further limit the scope of force majeure events by imposing extra-contractual requirements. For example, a non-performing party may be required to “demonstrate its efforts to perform its contractual duties despite the occurrence of the event that it claims constituted force majeure.”4 Such a party may also be required to show that the claimed triggering event was unforeseeable.5

In addition to considering whether a particular event is within the scope of a force majeure clause, it is important to determine whose performance must be impacted. If a clause applies only when one party’s performance is impaired, then an event that impacts the other party will not relieve the first party from performing.6 One must also determine whether the clause conditions relief on the provision of prompt written notice or the satisfaction of any other negotiated criteria.

If a recognized force majeure event occurs and the conditions for relying upon it are met, it is necessary to consider the type and duration of relief available. Most force majeure clauses allow parties to suspend performance for the duration of the force majeure event, take additional time for performance, and/or terminate the contract if the event continues for longer than an agreed time.7

Whether COVID-19 constitutes a force majeure event excusing performance will depend primarily on the language of the relevant contract. Although one court suggested in dicta that the avian flu may have qualified as a force majeure event because it was unforeseeable,8 there could be factual questions about whether and the extent to which COVID-19 was unforeseeable given prior global health emergencies involving SARS, Avian Flu, Swine Flu and the Zika virus. However, factors that could distinguish COVID-19 from previous situations include the dramatic impact COVID-19 has had on business due to the rapid spread of the virus, business closures, and travel restrictions, including the most recent prohibitions on certain travel to the U.S. It will likely be important, as well, to determine whether the virus has delayed or prevented performance under the contract or resulted in significant financial harm, since a change in market conditions – even a substantial one – has been found not to constitute a force majeure in the absence of language encompassing such an event.9 Ultimately, if there is ambiguity about the scope of the clause or factual disputes about the availability of relief, a trial would likely be required to resolve such issues.10

Extra-Contractual Defenses

Regardless of whether a contract contains a force majeure clause and whether it relieves a party from its contractual obligations, performance may also be excused through other defenses11, including frustration of purpose, impracticability and impossibility, though entitlement to these defenses is generally very difficult to establish, especially among sophisticated parties.

Frustration of Purpose

When the essential benefit expected under a contract is no longer available to a party through no fault of its own, the party may wish to consider whether performance may be excused under the doctrine of frustration of purpose. The Restatement, Second, of Contracts § 265 (1981) provides:

Where, after a contract is made, a party’s principal purpose is substantially frustrated without his fault by the occurrence of an event the non-occurrence of which was a basic assumption on which the contract was made, his remaining duties to render performance are discharged, unless the language or the circumstances indicate the contrary.

Frustration of purpose is typically asserted by the party required to pay under the contract. This is because the ability to pay is rarely impossible, but the purpose for paying the money may be frustrated. For example, a court discharged a restaurant from its obligation to make lease payments for a neon sign and tubing after the government implemented emergency war measures, ordering the cessation of all outside lighting in the district where the restaurant was located.12

Under New York law, frustration of purpose discharges a party’s performance when a “‘wholly unforeseeable event renders the contract valueless to one party.’”13 For the doctrine to apply, “the frustrated purpose must be so completely the basis of the contract that, as both parties understood, without it, the transaction would have made little sense.”14 And the frustrated purpose must be that of the party seeking to be excused from performance.15

Whether complications from COVID-19 will allow a party to be excused from performing under a contract will likely depend on whether the party seeking relief can persuade a fact-finder that its principal purpose for entering into the contract has been frustrated by such complications, through no fault of its own, and that the complications were unforeseeable.

Impracticability of Performance

When performance has become significantly more burdensome than anticipated due to an unforeseen event, a party may wish to consider whether its performance might be excused under the doctrine of impracticability of performance. The Restatement (Second) of Contracts § 261 (1981) states:

Where, after a contract is made, a party’s performance is made impracticable without his fault by the occurrence of an event the non-occurrence of which was a basic assumption on which the contract was made, his duty to render that performance is discharged, unless the language or the circumstances indicate the contrary.16

For example, where a power company entered into a contract with a contractor to remove and dispose of spent nuclear fuel, the court found the contractor’s performance was impracticable after the federal government unexpectedly discontinued reprocessing of nuclear fuel at that facility.17 The court found that because reprocessing the nuclear fuel was the only viable method of disposal and using an alternative facility would have cost the contractor more than $80 million, the contractor’s performance was impracticable.18

In determining whether relief is available under this doctrine, a court must conduct a highly fact-specific inquiry. Performance may be “impracticable because extreme and unreasonable difficulty, expense, injury, or loss to one of the parties will be involved.”19 “A severe shortage of raw materials or of supplies due to war, embargo, local crop failure, unforeseen shutdown of major sources of supply, which either causes a marked increase in cost or prevents performance altogether may bring the case within the rule....”20 It is not enough for performance to have become economically burdensome; it is also necessary that the cause of the burden be due to an unforeseen contingency, the absence of which was a basic premise of the parties’ agreement.21

Whether complications from COVID-19 will entitle a party to relief under the impracticability doctrine will likely depend not only on whether the complications were reasonably foreseeable but also on whether their impact results in extreme hardship that the parties did not anticipate or could not have reasonably anticipated.

Impossibility of Performance

If performance has become literally impossible due to an unforeseen event, performance might be excused under the doctrine of impossibility. However, the bar for establishing an entitlement to this defense is very high. Under New York law, performance is excused as impossible only where “an unanticipated event that could not have been foreseen or guarded against in the contract” makes performance “objectively impossible.”22 The impossibility defense is not available when performance becomes economically burdensome.23

It is well established that the impossibility defense may excuse performance when parties have been unable to perform due to governmental regulation or order that was not reasonably foreseeable.24 Such regulation or order may be domestic or foreign and may emanate from any level of government, including administrative agencies.25 At least one court has also recognized the viability of the defense in a case where a party claimed that the aftermath of September 11th prevented timely compliance with a termination provision, holding that if the party could establish objective impossibility, she would be entitled to reasonable suspension of her obligation to cancel timely or to a total excuse of untimely cancellation.26

Whether complications from COVID-19 will allow a party to be excused from a contract under the doctrine of impossibility will likely depend on whether and the extent to which the party seeking relief can persuade a fact-finder that performance was objectively impossible as a result of such complications. If performance depends on doing an act that has been prohibited by the government, such as traveling to the U.S., then a court could excuse performance as being objectively impossible. However, if reasonable parties could have taken or could take steps to perform in an alternative way, even if doing so is more expensive than performance would have been as originally contemplated, then a court would likely decide that performance is not excused under the doctrine of impossibility.


When a court finds that one of the extra-contractual defenses is applicable, the party claiming the defense generally has the balance of its performance excused, and the contract is rescinded. However, the court must then decide if additional remedies are applicable. For example, courts will often allow quantum meruit claims and award restitution of any benefits conferred on the non-performing party to avoid its receiving a windfall.27 The court may also grant other relief as justice requires, such as requiring the non-performing party to reimburse the performing party for expenses it incurred in reliance on the contract.28

Courts are generally reluctant to excuse performance based on the doctrines of frustration of purpose, impracticability or impossibility. Under the best circumstances, a court is likely to find there are factual questions about whether the requirements for invoking the doctrines have been met that necessitate a trial. If the court finds that the complications from COVID-19 were reasonably foreseeable, that they could have been addressed in a contract or that they did not have an effect on performance, the court is likely to deny relief under these extra-contractual doctrines.29
